PROCEDURE AND SYSTEM FOR MONITORING A PHYSIOLOGICAL PARAMETER WITHIN AN INTERNAL ORGAN OF A LIVING BODY
First Claim
1. A surgical procedure comprising:
- making a first incision in a living body to expose at least a portion of an internal organ of the living body, the organ having an internal cavity within which an internal physiological parameter is desired to be sensed;
making a second incision through an external wall of the organ and into the internal cavity;
placing a sensing unit in the second incision such that a proximal end of the sensing unit is outside the organ, the sensing unit consisting essentially of a sensing device having a sensing element adapted to sense the physiological parameter within the organ and an anchor to which the sensing device is secured, the sensing unit being placed in the second incision so that a distal end of the sensing unit does not extend more than one centimeter into the internal cavity;
securing the anchor to the external wall of the organ such that the sensing device is secured within the second incision by only the anchor and the second incision is occluded by only the sensing unit;
closing the first incision; and
thentelemetrically communicating with the sensing device to obtain a reading of the physiological parameter using a readout device located outside the living body.

Abstract
A system and surgical procedure for monitoring physiological parameters within an internal organ of a living body. The procedure entails making a first incision to expose the organ and a second incision through an external wall of the organ and into an internal cavity. A sensing unit is placed in the second incision such that a proximal end thereof remains outside the organ. The unit includes a sensing device having a sensing element for sensing the physiological parameter within the organ, and an anchor to which the sensing device is secured. The unit occludes the second incision and a distal end of the unit does not extend more than one centimeter into the cavity. The anchor is then secured to the wall of the organ, after which the first incision is closed and a readout device telemetrically communicates with the sensing device to obtain a reading of the physiological parameter.
