Abstract
A sensor implant device can include a shunt body that forms a fluid conduit, a first anchor structure associated with a first axial end of the shunt body, a second anchor structure associated with a second axial end of the shunt body, and a first sensor device coupled to the first anchor structure, the first anchor structure being configured to hold the first sensor device in a sensing position over a channel area of the fluid conduit.
Claims22
A sensor implant device comprising:
- a first sensor device;
- and
- a shunt body formed by a continuous helical wire coil, the helical wire coil defining:
- a first anchor flange at a first axial end of the shunt body formed by a first segment of the helical wire coil having a first diameter;
- a shunt fluid conduit adjacent to the first anchor flange, the shunt fluid conduit formed by a second segment of the helical wire coil having a second diameter that is less than the first diameter;
- a second anchor flange at an opposite axial end of the shunt fluid conduit from the first anchor flange, the second anchor flange formed by a third segment of the helical wire coil having a third diameter that is greater than the second diameter;
- and
- a first sensor-support arm formed of a fourth segment of the helical wire coil continuing from an end of the second anchor flange, the first sensor-support arm continuing in a winding path that reduces to a coil having a fourth diameter that is less than the second diameter and is configured to hold the first sensor device over a channel area of the shunt fluid conduit at a position distally beyond an axial boundary of the second anchor flange such that an axial flow gap is presented between the axial boundary of the second anchor flange and the first sensor device to provide an unobstructed flow channel in a plane of the axial boundary of the second anchor flange.

A sensor implant device comprising:
- a coil wireform winding in a first direction and comprising, in a deployed configuration:
- a shunt body portion formed of a plurality of winds of coil of the coil wireform and having a first diameter;
- a first flange anchor portion formed of one or more first winds of coil of the coil wireform emanating from a first axial end of the shunt body portion and having a second diameter that is greater than the first diameter;
- a first sensor-support arm formed of a continuous wire extension integrated with and emanating from the first flange anchor portion, the first sensor-support arm following a first curved path in the first direction and deflected radially over a channel area radially defined by the shunt body portion, a distal portion of the first sensor-support arm including a sensor-retention means holding a first sensor device;
- and
- a second flange anchor portion formed of one or more second winds of coil of the coil wireform emanating from a second axial end of the shunt body portion;
- wherein the first sensor-support arm is configured to hold the first sensor device at a position that is spaced beyond the first flange anchor portion such that an axial flow gap is presented between an axial boundary of the first flange anchor portion and a proximal-most portion of the first sensor device.
