Abstract: Balloon catheters for delivery of prosthetic hear valves is provided. The balloon catheters are configured to deploy a prosthetic heart valve through inflation. The balloon catheters are further configured with one or more retention bumpers to reduce or prevent migration of the prosthetic heart valve during delivery. Balloon catheters described herein are configured with substantially incompressible retention bumpers that promote longitudinal inflation fluid flow.

Abstract: A transcatheter heart valve delivery assembly includes a first shaft portion including a first wall surrounding a first chamber. A second shaft portion is attached to a distal end of the first shaft portion and includes a second wall surrounding a second chamber. A funnel portion is attached to a distal end of the second shaft portion and includes a funnel wall surrounding a funnel chamber. The funnel portion moves between a radially-compressed position, in which the funnel chamber includes a first diameter that is less than or equal to a diameter of the second chamber, and a radially-expanded position, in which the funnel chamber includes a second diameter that is greater than the first diameter. The funnel portion is biased into the radially-compressed position. Methods of recapturing a heart valve prosthesis are provided.

Abstract: An expandable introducer includes a hub having a distal end and a proximal end, and a sheath coupled to the hub and extending distally therefrom, the sheath defining a central lumen. The sheath is configured to radially expand from a radially unexpanded, folded state having a first diameter and to a radially expanded, unfolded state having a second diameter larger than the first diameter in response to a device passing through the central lumen. A wall of the sheath includes a thick wall region having a first wall thickness and a thin wall region having a second wall thickness smaller than the first wall thickness, wherein the thick wall region includes a coil embedded within the wall of the sheath.

Abstract: A system includes an inflow loading assembly configured to compress an inflow portion of the implantable medical device as the implantable medical device is advanced through the inflow loading assembly. The system also includes an outflow loading assembly removably coupled to the inflow loading assembly. The outflow loading assembly is configured to partially compress an outflow portion of the implantable medical device during coupling to the inflow loading assembly. The inflow loading assembly includes one or more biasing features that are configured to asymmetrically compress the inflow portion of the implantable medical device.
