Abstract:
1. A medical device comprising: an elongate member with a distal end portion and a proximal end portion with 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 of the elongate member comprises a proximal end face, the proximal end face has a first edge, the first edge traverses only a portion of a total circumference of the elongate member, the proximal end face transitions to a second face that is disposed distally of the proximal end face, the second face defining a second edge that traverses another portion of the total circumference of the elongate member, wherein each of the first edge and the second edge define at least a portion of a trough that allows for communication into the lumen from the proximal end portion, wherein a cross-section of the trough when viewed in a direction coaxial with a longitudinal axis of the device includes a first cross-sectional area, and a second cross-section of the trough when viewed from a perpendicular angle with respect to the longitudinal axis includes a second cross-sectional area that is greater than zero.
