Abstract

A system for monitoring blood pressure and other physiologic parameters is provided. The system is designed such that it can be delivered to the patient with ease and minimal invasion. The system contains at least one self contained implantable sensing device consisting of a sensor, an electrical circuit for signal conditioning and magnetic telemetry, a biocompatible outer surface and seal, an anchoring method, and an external readout device. The implant is small in size so that it may be delivered to the desired location and implanted using a catheter, although direct surgical implantation is also possible. The circuit, sensor, and antenna for telemetry are packaged together and sealed hermetically to the biologic environment. The larger readout unit remains outside the body but proximal to the implant for minimizing communication distance.

Claims

1. A miniature implant for measuring physiologic parameters for medical applications, comprising:

Implantable self-contained sensor module for measuring physiologic parameters wherein the module;

senses physiologic parameters with a sensor;

receives operating power from a magnetic field with an inductor coil;

conditions a sensor signal;

transmits a conditioned sensor signal to an external signal detection system via magnetic telemetry;

outer shell to house sensor module fit with anchoring mechanism for implantation.

2. The miniature implant of claim 1 wherein the implant is delivered and implanted with a catheter.

3. The miniature implant of claim 1 wherein the anchoring mechanism passes through a septum wall and opens on either side of a septal wall, clamping the implant to the wall.

4. The miniature implant of claim 1 wherein the anchoring mechanism is a helical screw.

5. The miniature implant of claim 1 wherein the anchoring mechanism is a tine that expands and catches on a trabeculated area of the heart.

6. The implant of claim 1 wherein said module is used for applications including but not limited to one or more of the following

cardiovascular diseases,

congestive heart failure,

congenital heart diseases,

diseases related to intracranial pressure,

abdominal aortic aneurysm,

intraocular pressure for eye related diseases including but not limited to glaucoma,

7. The implant of claim 1 wherein the sensor measures one or more of the following

parameters

pressure,

temperature,

flow,

blood composition,

blood gas content,

chemical composition,

acceleration,

vibration.
