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 transcatheter heart valve implant apparatus includes a frame extending along a frame axis and radially expandable between a first position and a second position. The frame includes a wire extending circumferentially around the frame axis to define a lumen. The wire includes a first peak portion including a first amplitude measured from a plane perpendicular to the frame axis, a second peak portion including a second amplitude measured from the plane, and a valley portion attaching the first peak portion and the second peak portion. The first amplitude is different than the second amplitude, and the first peak portion and the second peak portion are positioned on a first side of the plane and the valley portion is positioned on an opposing second side of the plane. A cover extends along the frame axis and covers an outer radial side of the wire opposite the lumen.
