MINIMALLY-INVASIVE PROCEDURE FOR MONITORING A PHYSIOLOGICAL PARAMETER WITHIN AN INTERNAL ORGAN
First Claim
1. A minimally-invasive surgical procedure for placing a sensing device through a wall of an internal organ of a living body to sense a physiological parameter in an internal cavity of the organ, the procedure comprising:
- making a first incision in the living body to enable access to the internal organ;
inserting an endoscopic instrument through the first incision and making a second incision therewith through an external wall of the organ and into the internal cavity thereof;
placing a sensing unit in the second incision such that a distal end of the sensing unit is within the wall or extends into the internal cavity and 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 internal cavity and an anchor to which the sensing device is secured;
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 minimally-invasive surgical procedure for monitoring a physiological parameter within an internal organ of a living body. The procedure entails making a first incision in the body to enable access to the organ. An endoscopic instrument is then inserted through the first incision and a second incision is made therewith through an external wall of the organ and into the internal cavity thereof. A sensing unit is placed in the second incision such that the second incision is occluded by the unit and a proximal end of the unit is outside the organ. The unit includes 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 first incision is closed, after which a readout device outside the body telemetrically communicates with the sensing device to obtain a reading of the physiological parameter.
