Abstract: Disclosed herein is a nickel-titanium alloy comprising nickel, titanium, and at least one rare earth element. The nickel-titanium alloy comprises from about 34 at. % to about 60 at. % nickel, from about 34 at. % to about 60 at. % titanium, and from about 0.1 at. % to about 15 at. % at least one rare earth element. The nickel-titanium alloy may further include one or more additional alloying elements. In addition to radiopacity, the nickel-titanium alloy preferably exhibits superelastic or shape memory behavior. Medical devices comprising the nickel-titanium alloy and a method of making them are also disclosed.

Abstract: A handle for receiving an elongate medical device is provided. The handle includes a housing defining an elongate hollow interior portion, the hollow portion defining a first portion proximate the distal end and the aperture, a second portion. A core is slidably disposed within the interior portion and includes a ramp portion extending from an outer surface of the core at an oblique angle to the longitudinal axis, and two or more arms extending outwardly from a proximal end of the core and biased toward an extended configuration where a proximal end of each arm extends radially outside of an outer surface of the core, wherein the two or more arms combine to define the proximal opening. A button is movably disposed within the aperture substantially blocking communication with the hollow portion through the aperture, comprising an inclined surface that slidably engages the ramp surface.

Abstract: Devices are illustrated which provide for accurately controlling the extension of a needle from a protective sheath to increase accuracy and improve the outcome of the treatment procedure.

Abstract: A stent is provided. The stent includes an elongate body comprising a tightly coiled wire disposed therealong, the coiled wire spanning between a first end portion and a second end portion, and defining a lumen therethrough. A safety wire is disposed through the lumen and fixed with respect to each of the first and second end portions. Proximal and distal end caps are fixed to the ends of the safety wire. At least one of the proximal and distal end caps comprises a window configured to receive the safety wire therethrough, and configured to allow access to the safety wire to weld the safety wire and the respective end cap.
