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; and

(d) a suture attachment wire for attaching at least one suture to secure the probe body to a predetermined sensor site, the suture attachment wire extending through the flexible tube and being releasably connected to the front of the elongate probe body, at least a portion of the suture attachment wire between the flexible tube and the front of the probe body extending exterior of the elongate probe body;

whereby the elongate probe body 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.

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

3. The implantable, extractable probe of claim 1 wherein the biological sensor is attached to the probe body such that upon implantation, said sensor will reset at a 5°

-85°

angle to the predetermined sensor site.

4. The implantable, extractable probe of claim 1 wherein the suture attachment wire is friction or compression loaded into a channel located in the front end of the probe body.

5. The implantable, extractable probe of claim 4 wherein the suture attachment wire is bent or looped to form two substantially equal lengths of wire, the two ends of the suture attachment wire being releasably connected to the front of the elongate probe body and extend through the flexible tube, at least a portion of each length 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.

6. The implantable, extractable probe of claim 1 wherein the suture attachment wire is bent or looped to form two substantially equal lengths of wire, the two ends of the suture attachment wire being releasably connected to the front of the elongate probe body and extend through the flexible tube, at least a portion of each length 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.

7. 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; and

(d) 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, wherein the suture attachment wire is bent or looped to form two substantially equal lengths of wire, the two ends of the suture attachment wire being releasably connected to the front of the elongate probe body and extend through the flexible tube, at least a portion of each length 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;

wherein the probe body has sides and is provided with two cut-outs on each side, and where one length of suture attachment wire extends through both cut-outs on one side of the probe body, while the other length of suture attachment wire extends through both cut-outs on the other side of the probe body, whereby the exposed lengths of suture attachment wire are spaced a predetermined distance from the probe body and provide suture attachment points to secure the probe in place at a monitoring site

whereby the elongate probe body 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.
