Abstract

A leadless intravascular sensor (100, 200) uses the body tissue as a communication medium. The implantable intravascular device has a tubular stent-like structure (102) for intravascular fixation with embedded microcircuits to allow bipolar and unipolar sensing of cardiac and neurologic electrical activity, sensing of other physiologic signals, local electrical stimulation (cardiac pacing and defibrillation; neurologic stimulation and seizure therapy) as well as the ability to communicate with other implanted and non implanted devices via radio frequency and/or optical communication and/or analog signal communication using the body tissue as the conducting medium. The device can also be used in the extravascular or perivascular space. In this form, it has an open/flexible ring that can be adjusted, or self-adjusts to provide no pressure or required contact around the vessel or target region.

Claims

1. A intravascular device (100) comprising:

a body (102) generally forming an elongated tubular shape and an electronic component (106) secured to the body.

2. The device of claim 1, wherein said electronic component includes a wireless transmitter for wireless communication.

3. The device of claim 1, wherein said body comprises a support structure having a pattern, and said electronic component comprises a coil secured to the support structure.

4. The device of claim 3, wherein the coil has a pattern that follows the support structure pattern.

5. The device of claim 1, wherein said device can be secured at a target intravascular site.

6. The device of claim 1, wherein said electronic component senses electrical conditions of a patient.

7. The device of claim 1, wherein said electronic component senses physiologic conditions of a patient.

8. The device of claim 1, wherein said electronic component imparts a stimulation to the patient.

9. The device of claim 1, wherein said electronic component imparts an electrical stimulation to the patient.

10. The device of claim 1, wherein said device is expandable.

11. The device of claim 10, wherein said device is delivered intravascularly to a target site and expanded at the target site to be fixed in position at the target site.

12. The device of claim 1, wherein the device is leadless.

13. The device of claim 1, wherein the body has a stent-like structure.

14. The device of claim 1, wherein said device can be networked with other extravascular or intravascular devices.

15. An extravascular sensor comprising:

a body generally forming an elongated tubular shape having a longitudinal opening and an electronic component secured to said body.

16. The device of claim 15, wherein said body comprises a support structure having a pattern, and said electronic component comprises a coil secured to the support structure.

17. The device of claim 16, wherein the coil has a pattern that follows the support structure pattern.
