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.
Core Innovation
The sensor implant device comprises a shunt body formed by a continuous helical wire coil defining first and second anchor flanges and a shunt fluid conduit. A sensor-support arm extends from an anchor flange to hold a sensor over the conduit channel area beyond an axial boundary of the flange. This configuration establishes an axial flow gap that presents an unobstructed flow channel in the plane of the flange boundary.
In another configuration, the coil-wireform sensor implant features an integrated sensor-support arm formed from a continuous wire extension emanating from a flange anchor portion. The support arm follows a curved path over the channel area and includes sensor-retention means holding the sensor beyond the flange while preserving the axial flow gap. Disclosed variants include alternative support arrangements, conduit covers or seals, and placement across cardiac tissue.
Claims Coverage
The claims recite two independent claims providing two inventive features directed to sensor implant configurations formed from a helical wire coil or coil wireform.
Helical coil shunt with sensor-support arm
A continuous helical wire coil forms a shunt body with first and second anchor flanges and a shunt fluid conduit, wherein a sensor-support arm continues from the second anchor flange and holds a sensor device over the conduit channel area distally beyond the flange axial boundary, presenting an axial flow gap that provides an unobstructed flow channel.
Coil-wireform shunt with integrated sensor-support arm
A coil wireform comprises a shunt body portion, first and second flange anchor portions, and a sensor-support arm formed of a continuous wire extension integrated with the first flange anchor portion, wherein the arm follows a curved path over the channel area and retains a sensor beyond the flange anchor portion to present an axial flow gap.
The independent claims cover coil-based shunt implants that secure a sensor beyond an anchor flange while presenting an axial flow gap, differing in specific coil parameters, continuous wire extensions, and sensor-retention structures.
Stated Advantages
The sensor positioning creates an axial flow gap that provides an unobstructed flow channel in the plane of the anchor flange axial boundary.
Documented Applications
Wireless physiological-pressure monitoring in a clinical context using a sensor implant communicating with external, secondary-local, or remote monitors.
Cardiac shunt implantation across cardiac tissue, including the left and right atria, using catheter delivery configurations and vascular access routes.
