Abstract

An implantable, extractable probe for attachment to a vessel or organ. The probe is made up of an elongate probe body having front and rear ends, and top and bottom sides, the elongate probe body terminating in a flexible tube. The probe has at least one biological sensor attached to the bottom side of the probe body with at least one lead wire connected to the biological sensor, and the lead wire extends through the flexible tube. The probe includes a suture attachment wire for attaching at least one suture to secure the probe body to a predetermined sensor site, the suture attachment wire being releasably connected to the front of the elongate probe body and extending through the flexible tube, at least a portion of the suture attachment wire extending between the front of the elongate probe body and the flexible tube such that it is spaced a predetermined distance from the probe body. The probe may be secured to a predetermined sensor site by attaching at least one suture to the suture attachment wire, such that when the suture attachment wire is released, the probe body is released for extraction from the body.

Claims

1. An implantable, extractable probe for attachment to a vessel or organ comprising:

(a) an elongate probe body having front and rear ends, the elongate probe body terminating in a flexible tube;

(b) at least one biological sensor attached to the probe body;

(c) at least one lead wire connected to the biological sensor, said lead wire extending through the flexible tube;

(d) an inflatable balloon situated on the probe body; and

(e) suture securing means attached to the probe body and looped over the balloon, such that the probe body is secured by inflating the balloon and released for extraction from the body by deflating the balloon.

2. The implantable, extractable prove of claim 1 wherein the biological sensor is an ultrasound transducer.

3. The implantable, extractable probe of claim 2 wherein the biological sensor is attached to the probe body so that upon implantation, said sensor will rest at a 5°

-85°

angle to a predetermined sensor site.
