Introduction

The Medtronic® Model 7432 Physician Programmer isdesigned for use by a physician to noninvasivelyprogram Medtronic neurostimulators. In addition tostimulation mode and parameter value programmingcapabilities, the physician programmer receives andprocesses telemetry signals transmitted from theneurostimulators. See the appropriate MemoryMod®

Software Cartridge technical manual for specificparameter and mode programming capabilities.

The physician programmer is an advancedmicroprocessor-based device with functions andoperations controlled by software contained withinplug-in cartridges called MemoryMod SoftwareCartridges. This interchangeable software featureallows the programmer console capabilities to beexpanded as new neurostimulators and programmingfunctions become available. New software cartridges

are easy to install and allow the physicianprogrammer to be kept current in a rapidly changingtechnical environment.

To accommodate the flexibility of the replaceablesoftware system, the technical instructions for theprogrammer are divided into two parts. The first partis this manual, which describes the programmersystem “hardware” and provides service informationfor changing the batteries, replacing the printer paper,etc. This manual is designed to fit in the programmerstorage case and should be kept with the system.

The second part is a separate technical manualsupplied with each software cartridge. The “software”manual describes specific applications and functionswhich are controlled by that particular softwarecartridge. Software cartridges are programmed byMedtronic and cannot be reprogrammed by the user.Refer to the appropriate software cartridge technicalmanual for specific instructions.

195232_e_004.qxd 12/21/01 11:18 AM Page 1

WarningDevice Compatibility—The Physician Programmermust be used only for programming the Medtronicneurostimulators listed as applicable units. A list ofapplicable model numbers is included in the softwarecartridge technical manual supplied with eachsoftware cartridge. The physician programmer is notcompatible with programmable devices made by othermanufacturers.

PrecautionsPreparation for Programming—Programmingshould be done only after careful study of theneurostimulator or system technical manual. Refer tothe neurostimulator or system technical manual fordetails of neurostimulator operation and a completelist of indications, contraindications, warnings, andprecautions.

Reprogramming—DO NOT make large changes inthe programmable parameters. Parameter changesshould be made gradually and in small increments orundesirable stimulation could result.

Operating Temperature—If the physicianprogrammer was transported or stored attemperatures above or below the specified operatingtemperature range (listed in “System Specifications”),the physician programmer should be allowed tostabilize at a temperature within the range specifiedbefore it is used for programming.

Programming Different Neurostimulator Models—The Model 7432 Physician Programmer must beturned off and turned back on before attempting toprogram a different neurostimulator model (forexample, if programming a Soletra Model 7426neurostimulator immediately after programming anItrel II Model 7424 neurostimulator). If theprogrammer is not turned off and on, the programmer

2

195232_e_004.qxd 12/21/01 11:18 AM Page 2

will display “NO TELEMETRY, POSITION HEAD ANDTRY AGAIN” and the software will not allow thedifferent neurostimulator to be programmed.

Programming Head Placement—If the programminghead is not properly aligned over the neurostimulator,programmed parameters may not change. Theprogramming head must be held steady over theneurostimulator for at least three seconds after thePROGRAM key is pressed.

Figure 1. Model 7432 Physician Programmer.

The Medtronic Model 7432 Physician Programmer ispart of a neurostimulation programming system(Figure 1). The programming system consists of theprogrammer, programming head, printer, softwarecartridge, and carrying case. The MemoryModSoftware Cartridge is packaged separately and isrequired for programmer operation.

Programmer Console DisplaysThe programmer console has two liquid crystaldisplay (LCD) panels that operate continuouslythroughout a programming sequence to provide allthe instructional messages and entry options requiredto complete a programming sequence. Both displaysare divided into segments that coincide with anadjacent row of unlabeled keys. This allows the userto select the desired option from a displayed “menu”of choices by pressing the associated key (see thesoftware cartridge technical manual for more details).

Programming SystemDescription

195232_e_004.qxd 12/21/01 11:18 AM Page 4

The interaction of the upper and lower displays andthe associated keys will guide the user through acomplete programming sequence.

Lower Display

The lower display consists of two lines of 40characters each. During a programming sequence,this display typically shows instructional messages orprompts on the first line and a list of appropriatechoices on the second line. Graphics along the bottomborder of the display divide it into eight segmentswhich coincide with eight multi-function or “soft” keyslocated below the display. Some informational messagesrequire both lines of the display.

Upper Display

The top line of the upper display is designed primarilyto display the neurostimulator parameter values asobtained by telemetry. The appropriate parameterdesignations appear at fixed locations within theoutlined sections of the display. These sectionscoincide with the ten parameter selection keyslocated above the display. The lower line of the upperdisplay is used for prompts and selection messages.

195232_e_004.qxd 12/21/01 11:18 AM Page 5

Viewing Angle and Contrast Adjustment

Liquid crystal displays like those used in theprogrammer console have an optimum viewing anglewhich provides the greatest contrast between thedisplayed characters and the background. Theprogrammer console has a control located on thelower left end of the device that rotates the displayviewing angle, starting at perpendicular and rotatingdownward. To adjust the viewing angle, turn thecontrol clockwise or counterclockwise as required formaximum contrast (Figure 2).

Note: Under fluorescent lighting, the programmerconsole displays may appear to flicker. This isnormal and does not indicate a malfunction.

Keyboard FunctionsAll functions of the programmer console aremicroprocessor controlled according to the entriesmade on the programmer console keyboard.Functional layout of the keyboard (Figure 3) dividesthe keys into three groups as follows:

• ten keys across the top are used with the upperdisplay to select a parameter for programming

• eight keys across the bottom are used with thelower display to select the parameter value, orspecial function

• twelve dedicated function keys and the on/off keyto the right of the display are used to select orinitiate a specific function.

Note: Pressing an inactive key will not result inany programming or item selection.

The Programmer ConsoleThe programmer console is a battery-powered devicedesigned to noninvasively program the adjustablefunctions of Medtronic neurostimulators. Theprogrammer console can receive and processtelemetry signals from neurostimulators with telemetrycapabilities.

All keys controlling operation of the system are laidout in three functional groups around two liquidcrystal displays (LCDs) on the face of theprogrammer console. Other external features include:two sockets on the top edge of the programmerconsole for connecting the printer and programminghead; a control knob on the left-hand edge foradjusting the display viewing angle; a battery accesspanel on the right-hand edge; and a compartment inthe upper left-hand corner for a MemoryMod SoftwareCartridge.

A switch labeled AC/BATT is also located on the topedge of the programmer console. This switch must bein the BATT position to operate the programmer usingthe batteries. The jack near the switch is for theMedtronic Model 9740 AC Adapter. Do not use thisjack for anything other than the Model 9740 ACAdapter.

The programmer console is powered by three,commercially available, 9-volt alkaline batteries. Foradditional information about the programmer console,see Table 2.

27

195232_e_004.qxd 12/21/01 11:18 AM Page 27

The Programming HeadThe Medtronic Model 7432V Programming Head mustbe connected to the programmer console and heldover the neurostimulator during a programmingtransmission and telemetry reception. Theprogramming head contains transceiver componentsincluding a radio-frequency (RF) transmitting andreceiving antenna.

A gain switch at the base of the programming headenables the user to improve telemetry reception. Ithas five positions ranging from L (low) to H (high).The presence of electrical interference strong enoughto interrupt reception of telemetry from theneurostimulator can affect the operation ofprogramming confirmation.

Communication between the programmer consoleand the neurostimulator for both programming andtelemetry is via transmission of binary-coded RFpulses. The PROGRAM and REVIEW keys on theprogramming head may be used as alternatives tothose keys on the programmer console.

During each programming sequence, a red indicatoron the programming head (and programmer console)labeled POSITION HEAD comes on to indicate thatthe programming head must be centered over theneurostimulator prior to initiating a programmingtransmission.

The programming head plugs into the RF HEADsocket located on the top of the programmer console.The plug and socket are color-coded blue.

28

195232_e_004.qxd 12/21/01 11:18 AM Page 28

The PrinterThe Medtronic Model 7451 Printer plugs into theprogrammer console to provide a hard copy of eachuse of the programmer console. The printer has bothalphanumeric and graphic printing capabilities.Information printed includes telemetered mode andparameter settings and battery status. An informationheading is automatically included on the printout.

The printer uses a replaceable cartridge-type ink penand prints on 4 1/2 inch-wide paper fed from areplaceable roll. Thermal (heat sensitive) paper is notused. The printer is self-powered by four, 9-voltalkaline batteries of the same type as those used inthe programmer console. The printer has a built-inmemory for storing data that accumulates when thedata is received faster than it can be printed. Thisfeature allows the user to continue a programmingsequence without interruption even though the printermay lag behind the operation.

The printer has three controls: ON/OFF key, PAPERADVANCE key, and PEN CHANGE key that allowsreplacement of the pen cartridge. The printer will notrespond to commands from the programmer consoleunless the printer power is turned on. An amberindicator above the ON/OFF key indicates when theprinter power is on. The indicator flashes when theprinter batteries are low and should be replaced. Theprinter paper can be advanced by pressing andholding the PAPER ADVANCE key.

The printer plugs into the PRINTER socket on the topof the programmer console. The plug and socket arecolor-coded gray. The programmer console may beoperated without the printer if desired. A switchlabeled AC/BATT is located along the right-hand edgeof the printer. This switch must be in the BATTposition to operate the printer using the batteries. Thejack near the switch is for the Medtronic Model 9740AC Adapter. Do not use this jack for anything otherthan the Model 9740 AC Adapter.
