Abstract:
1. A multi-functional wire guide assembly, comprising: an elongate tubular housing having a length and defining a lumen extending from an open proximal end of the elongate tubular housing to an open distal end of the elongate tubular housing; a first mandril positioned within the lumen, extending a majority of the length of the elongate tubular housing, having a portion of an outer surface attached to an inner surface of the elongate tubular housing at an attachment joint, and having a fixed position relative to the elongate tubular housing, and a segment of the attachment joint being remote from a distal end of the first mandril and being remote from the distal end of the elongate tubular housing; and a second mandril positioned within the lumen, having a length greater than the length of the elongate tubular housing, and axially movable relative to the elongate tubular housing; wherein the multi-functional wire guide assembly has a first configuration in which a distal tip of the second mandril is proximally spaced from a distal segment of the elongate tubular housing and a second configuration in which the distal tip of the second mandril is axially aligned with the distal segment; and wherein the first mandril and the second mandril are exposed to fluid passing through the lumen.
