Abstract: Described herein are systems and methods from delivering prosthetic devices, such as prosthetic heart valves, through the body and into the heart for implantation therein. The prosthetic devices delivered with the delivery systems disclosed herein are, for example, radially expandable from a radially compressed state mounted on the delivery system to a radially expanded state for implantation using an inflatable balloon of the delivery system. Exemplary delivery routes through the body and into the heart include transfemoral routes, transapical routes, and transaortic routes, among others.

Abstract: A sheath assembly can comprise a removable hub. The removable hub can have a lumen extending therethrough and comprise a first circumferential hub portion that spans a first circumferential segment about a longitudinal axis of the removable hub, a second circumferential hub portion that spans a second circumferential segment about the longitudinal axis of the removable hub, and first and second connector portions connecting the first circumferential hub portion and the second circumferential hub portion. The second circumferential segment can be greater than the first circumferential segment. The sheath assembly can comprise a removable shaft configured to extend distally from a distal end of the removable hub, the removable shaft being configured such that separation of the first circumferential hub portion from the second circumferential hub portion causes a first circumferential shaft portion to separate from a second circumferential shaft portion.

Abstract: A method comprises delivering a first implant to an orifice of a chamber of a heart, anchoring the first implant at the orifice, delivering a sensor device to the orifice, and coupling the sensor device to the first implant.

Abstract: A sensor implant system comprises a shunt implant comprising a central flow portion configured to maintain an opening through a tissue wall and a sensor implant device.

Abstract: Embodiments of a catheter assembly are disclosed. The catheter assembly comprises a shaft; a connector assembly comprising a first connector portion and a second connector portion, wherein the first connector portion is fixedly coupled to a distal end of the shaft, and is rotatably coupled to the second connector portion by at least one radially extending pin retained within at least one slot on the second connector portion, wherein the at least one slot has an oversized circumferential dimension that allows limited rotation of the second connector portion relative to the first connector portion about a longitudinal axis of the shaft.

Abstract: Embodiments of a catheter assembly are disclosed. The catheter assembly comprises a shaft; at least one connector assembly. The connector assembly can comprise a first connector portion and a second connector portion, wherein the first connector portion is fixedly coupled to a distal end of the shaft, and is coupled to the second connector portion with a limited degree of freedom of movement by at least one radially extending pin retained within at least one slot on the second connector portion. The at least one slot can have an oversized circumferential dimension that allows limited rotation of the second connector portion relative to the first connector portion about a longitudinal axis of the shaft.

Abstract: A sensor implant device includes a shunt body that forms a fluid conduit, the fluid conduit having an axis, a first anchor structure associated with a first end of the shunt body, and a first sensor device coupled to the first anchor structure such that a sensor transducer of the first sensor device projects into a channel area defined by a radial boundary around the axis of the fluid conduit, the radial boundary being defined by the fluid conduit.

Abstract: A prosthetic valve can comprise a body member having a first end and a second end, the body member defining a conduit and being configured to assume a compressed configuration and an expanded configuration, a lateral dimension of the body member being larger in the expanded configuration than that in the compressed configuration. An elongate member can have a first end associated with the first end of the body member, the elongate member being configured to move between a longitudinal orientation and a diametrical orientation. A covering can be coupled to the elongate member and configured to cover at least a portion of the conduit at the first end of the body member when the elongate member is in the diametrical orientation.

Abstract: A delivery sheath includes an outer tubular layer and an initially folded inner tubular layer. When an implant passes therethrough, the outer tubular layer expands and the inner tubular layer unfolds into an expanded lumen diameter. The sheath may also include selectively placed longitudinal support rods that mediate friction between the inner and outer tubular layers to facilitate easy expansion, thereby reducing the push force needed to advance the implant through the sheath's lumen.
