Abstract

A medical device is provided. The device includes a generally elongate member with distal and proximal end portions and a longitudinal axis and a lumen disposed therethrough, wherein the lumen is configured to allow the passage of a wireguide therethrough. The proximal end portion defines a trough for accepting a tip of the wireguide and urging the tip into the lumen from a varying angle of attack with respect to the longitudinal axis. The trough is defined from an open proximal end that provides communication with the lumen. The trough includes a proximal end face with an arcuate first edge that traverses only a portion of a total circumference of the elongate member. The proximal end face transitions to a second face disposed distally of the proximal end face. The second face defines a second edge that traverses another portion of the total circumference of the elongate member.
