Abstract

Claims (30)

1 . An implantable medical system, the system comprising:

a first device carrying one or more first electronic components and configured to be implanted in a patient;

a second device carrying one or more second electronic components and configured to be implanted in the patient; and

a communication assembly extending between and physically coupling the first device and the second device, wherein the communication assembly includes—

one or more first wires having a helical configuration, wherein the one or more first wires are configured to wirelessly transmit and/or receive data, and

one or more second wires having a linear configuration and extending within the one or more first wires, wherein the one or more second wires are configured to conductively transfer power from the one or more second electronic components to the one or more first electronic components.

2 . The system of claim 1 wherein the communication assembly is flexible.

3 . The system of claim 1 wherein the communication assembly has a length, and wherein the one or more first wires extend along less than the length of the communication assembly.

4 . The system of claim 3 wherein the one or more first wires extend between about 50% and 95% of the length of the communication assembly.

5 . The system of claim 1 wherein the communication assembly further comprises an insulation sleeve, and wherein:

the one or more first wires are wrapped around a radially outer surface of the insulation sleeve, and

the one or more second wires extend coaxially within the insulation sleeve.

6 . The system of claim 5 wherein the insulation sleeve is composed of a thermally insulative material.

7 . The system of claim 5 wherein the insulation sleeve is composed of an electrically insulative material.

8 . The system of claim 5 wherein the insulation sleeve is a first insulation sleeve, and wherein:

the communication assembly further comprises a second insulation sleeve, and

the one or more first wires are positioned between the first insulation sleeve and the second insulation sleeve.

9 . The system of claim 1 wherein the one or more second wires include at least two second wires.

10 . The system of claim 1 wherein the one or more first wires have:

a pitch between about 0.5 mm and about 5 mm,

an outer diameter between about 0.8 mm and about 1.4 mm, and

an inner diameter between about 0.7 mm and about 1.3 mm.

11 . The system of claim 1 wherein the one or more first wires include a ribbon wire.

12 . The system of claim 8 wherein the one or more first wires are configured to wirelessly transmit and/or receive data within a first frequency range of from 800 MHz to 1 GHz.

13 . The system of claim 1 wherein the one or more first electronic components include a sensor or a microcontroller, and wherein the one or more second electronic components include an energy storage component.

14 . A method of operating an implanted medical device having a first canister housing one or more first electronic components and a second canister housing one or more second electronic components, the method comprising:

wirelessly transmitting data between the first canister and a controller positioned external to the patient via one or more first wires, wherein the one or more first wires have a helical configuration and extend at least partially between the first canister and the second canister; and

conductively transmitting power from the one or more second electronic components to the one or more first electronic components via one or more second wires extending between the first canister and the second canister, wherein the one or more second wires have a linear configuration and extend within the one or more first wires.

15 . The method of claim 14 wherein the one or more first electronic components include a sensor or a microcontroller, and wherein the one or more second electronic components include an energy storage component.

16 . The method of claim 14 wherein wirelessly transmitting data between the first canister and the controller includes wireless transferring data within a frequency range of from 800 MHz to 1 GHz.
