Appl. No.:

12/111954

Inventors:

Nader Najafi - Ann Arbor MI, US
Sonbol Massoud-Ansari - El Dorado Hills CA, US
Catherine Hook Morgan - Ann Arbor MI, US

Assignee:

Integrated Sensing Systems, Inc. - Ypsilant MI

International Classification:

A61B 5/07

US Classification:

600302

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.

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.

International Classification:

A61B 5/00

US Classification:

600561

Abstract:

An anchor for an implantable sensing device, a sensor unit formed by the anchor and sensing device, and a surgical procedure for implanting the sensor unit for monitoring a physiological parameter within a cavity of a living body, such as an intracranial physiological property. The anchor includes a shank portion and a head portion. The shank portion defines a distal end of the anchor and has a bore defining an opening at the distal end. The head portion defines a proximal end of the anchor and has a larger cross-sectional dimension than the shank portion. The sensor unit comprises the anchor and the sensing device placed and secured within the bore of the anchor so that a sensing element of the sensing device is exposed for sensing the physiological parameter within the cavity.

US Classification:

600486, 600483, 600485

Abstract:

A delivery method and system for noninvasively monitoring cardiac physiologic parameters used to evaluate patients with cardiovascular conditions. The system includes an implantable sensing device configured for chronic implantation in a cavity of the cardiovascular system, such as the heart, pulmonary artery (PA), etc. The method involves introducing the sensing device through a cardiovascular cavity that is upstream in the vasculature from the cavity where implantation is intended and has a larger diameter than the intended cavity, and thereafter blood flow through the cardiovascular system delivers the device to the intended cavity. The device is sized and configured so as to secure itself within the intended cavity when the device moves through the cavity to a point where the diameter narrows sufficiently to secure the device and so as to be oriented once secured to sense a pressure either within, upstream (wedge), or downstream (distal) of the cavity.

US Classification:

128899, 72324

Abstract:

An anchor for a medical implant, methods of manufacturing the anchor, and procedures for placing a medical implant, such as for diagnosing, monitoring and/or treating cardiovascular diseases. The anchor has a base portion with first and second longitudinal ends and a cage therebetween. The anchor further has flexible arms, flexible legs, features for securing the medical implant within the cage of the base portion, and a coupler portion connected to and spaced apart from the second longitudinal end of the base portion. The anchor is adapted to have a deployed configuration in which the arms and legs radially project away from the base portion, the arms axially project toward the second longitudinal end of the base portion, and the legs axially project toward the first longitudinal end of the base portion. Convex surfaces of the arms and legs are adapted to clamp the anchor to a wall.

US Classification:

606 1

Abstract:

A delivery system and method for placing a medical implant, such as for diagnosing, monitoring and/or treating cardiovascular diseases. The delivery system includes a hollow catheter, an anchor coupled to the catheter, and an implant secured within the anchor. The anchor has a base portion with first and second longitudinal ends and a cage therebetween. The anchor further has flexible arms, flexible legs, features for securing the medical implant within the cage of the base portion, and a coupler portion connected to and spaced apart from the second longitudinal end of the base portion. Surfaces of the arms and legs are adapted to clamp the anchor to a wall. The system further includes a pusher wire adapted to cause the anchor to acquire a stowed configuration in which the legs axially extend from the base portion, permitting the anchor to be retrieved after its deployment.
