    摘要： A catheter apparatus for assessing denervation comprises: an elongated catheter body; a deployable structure coupled to the catheter body, the deployable structure being deployable outwardly from and contractible inwardly toward the longitudinal axis of the catheter body; one or more ablation elements disposed on the deployable structure to move outwardly and inwardly with the deployable structure; one or more stimulation elements spaced from each other and disposed on the deployable structure to move with the deployable structure, the stimulation elements being powered to supply nerve stimulating signals to the vessel; and one or more recording elements spaced from each other and from the stimulation elements, the recording elements being disposed on the deployable structure to move with the deployable structure, the recording elements configured to record response of the vessel to the nerve stimulating signals.

    摘要： A prosthetic heart valve includes an annular frame that is adapted for (1) delivery into a patient's native heart valve annulus in a circumferentially collapsed condition, and (2) circumferential re-expansion when in the annulus, the frame, in an expanded condition. The frame having a longitudinal axis, an inflow end and an outflow end, a first portion of the frame adjacent the inflow end inclining radially outwardly in a direction toward the inflow end, and a second portion of the frame between the first portion and the outflow end bulging radially outwardly, the second portion of the frame being positioned between a first axial distance from the inflow end and a second axial distance from the inflow end. The frame also includes a plurality of commissure members. The heart valve further includes a flexible leaflet structure disposed in the frame.

    摘要： A delivery system for delivering a collapsible prosthetic heart valve includes a valve support structure for supporting a collapsible prosthetic heart valve, and a distal sheath movable in a longitudinal direction relative to the valve support structure between a first position in which the distal sheath is adapted to surround a collapsible prosthetic heart valve supported on the valve support structure, and a second position in which the distal sheath is adapted to expose the collapsible prosthetic heart valve for deployment. The distal sheath is at least partially formed of an inner polymer layer, an outer polymer layer, and a tubular supporting member sandwiched between the inner polymer layer and the outer polymer layer.

    摘要： A delivery system for delivering and deploying a medical implant, such as a prosthetic heart valve, includes an elongated support member, a sheath, and a tip. The sheath is movable relative to the elongated support member between a distal position overlying the medical implant and a proximal position exposing the medical implant for release from the delivery system. The tip is attached to the elongated support member and is positioned at a distal end of the sheath when the sheath is in the distal position. The tip has a compressed condition and an expanded condition, and a maximum diameter in the expanded condition that is larger than the outer diameter of the sheath.

    摘要： A prosthetic heart valve includes an annularly collapsible and re-expandable supporting structure extending between an inflow end and an outflow end and including a plurality of struts, the inflow end having an inflow edge, a plurality of leaflets disposed inside the supporting structure and operative to allow flow in an antegrade direction from the inflow end to the outflow end but to substantially block flow in a retrograde direction from the outflow end to the inflow end, a first material disposed on a luminal surface of the supporting structure adjacent the inflow end, and a second material disposed on an abluminal surface of the supporting structure adjacent the inflow end, the first material and the second material being secured to selected struts of the supporting structure, and separately secured to each other adjacent the inflow edge.
