Abstract: A medical implant system (1) comprises an access sheath (2) having a lumen (3), an implant system disposed within and axially adjustable relative to the lumen (3) of the access sheath (2) and comprising an implant (6) that is radially adjustable from a contracted delivery configuration to a radially expanded deployed configuration detachably coupled to an implant delivery shaft (4) having a lumen (5), an anchoring system mountable within and axially adjustable relative to the lumen (5) of the implant delivery shaft (4) comprising an anchor (8) that is radially adjustable from a contracted delivery configuration to a radially expanded implant anchoring configuration detachably coupled to an anchor delivery shaft (7), and a handle (9) configured to be operatively coupled to the implant delivery shaft (4) and access sheath (2) and comprising an axial actuator to adjust the axial position of the implant delivery shaft (4) relative to the access sheath (2) to deploy and/or recapture the implant (6).

Abstract: Systems, apparatus, and methods that provide a flexible current sensor capable of measuring current flowing through a conductor without contacting the conductor. In various implementations, a flexible current sensor may have a comparable size, shape, and appearance as a flexible loop of a Rogowski coil, except the current sensor described herein can sense direct current (DC). The current sensors of the present disclosure utilize a novel open loop degaussing mechanism to provide accurate DC current measurements in a conductor. To achieve this, a current sensor includes an AC degaussing coil wrapped around a magnetic core. A driver circuit drives an AC degaussing signal in the AC degaussing core, which operates to reset or degauss the magnetic core, thereby providing more accurate current measurements.

Abstract: A device to occlude a body lumen such as the left atrial appendage of a heart of a subject is described. The device comprises an implantable occlusion apparatus comprising a proximal connecting hub and a radially expansible body configured for radial expansion upon deployment from a contracted configuration to a radially expanded configuration to fluidically occlude the left atrial appendage, an elongated deployment catheter having a central lumen, an elongated delivery catheter disposed in the central lumen of the elongated deployment catheter and having a distal connecting hub detachably attachable to the proximal connecting hub of the implantable occlusion apparatus for transluminal delivery of the implantable occlusion apparatus to the left atrial appendage, wherein the elongated deployment catheter is axially movable proximally relative to the elongated delivery catheter to deploy the implantable occlusion apparatus.
