Abstract

An antenna implantable through minimally invasive techniques, preferably comprising a coil with conductive probes is provided. The antenna is preferably superelastic nickel-titanium having an insulative coating. The antenna may conduct a signal originating from a device external to the body of the implantee, or from another implanted device connected to the antenna depending on whether the antenna is employed for sending, receiving, or transceiving signals. Signals may contain data, operational commands, and may be used to transfer power. The implantable antenna may be connected to another implanted device, such as a blood pressure monitor, or may be implanted as a stand-alone device for purposes such as stimulating tissue.

Claims

1. An implantable inductive device comprising an antenna having a coil section, including one or more windings, and a lead section including at least one lead positioned a predetermined distance from the coil section, at least one of the one or more windings of the coil section and the at least one lead of the lead section being formed from a superelastic material, the antenna being configurable for implantation via minimally invasive medical instruments.

2. The implantable inductive device according to claim 1, wherein the superelastic material comprises a nickel-titanium alloy.

3. The implantable inductive device according to claim 2, wherein the nickel-titanium alloy comprises from about 50 weight percent to about 60 weight percent nickel and the remainder titanium.

4. The implantable inductive device according to claim 1, wherein the antenna is coated with a biocompatible, insulative coating.

5. The implantable inductive device according to claim 1, wherein the antenna is configured for communication with other devices.

6. The implantable inductive device according to claim 1, wherein the antenna is configured as a stand alone device.

7. The implantable inductive device according to claim 1, wherein the at least one lead is configured for direct stimulation of body tissue at the implant site.

8. The implantable inductive device according to claim 1, wherein the device comprises a receiver.

9. The implantable inductive device according to claim 1, wherein the devices comprises a transmitter.

10. The implantable inductive device according to claim 1, wherein the devices comprises a transceiver.
