Multi-functional wire guide assembly and method of using same
First Claim
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.

Abstract
A multi-functional wire guide assembly includes 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 is positioned within the lumen, extends a majority of the length of the elongate tubular housing, and has a fixed position relative to the elongate tubular housing. A second mandril is positioned within the lumen, has a length greater than the length of the elongate tubular housing, and is axially movable relative to the elongate tubular housing. 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.

10. A method of performing a percutaneous vascular procedure using a multi-functional wire guide assembly, wherein the multi-functional wire guide assembly includes 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, the method comprising steps of:
-
moving the multi-functional wire guide assembly into a first configuration to provide a first tip load; advancing the multi-functional wire guide assembly through a vessel of a patient at the first tip load; moving the multi-functional wire guide assembly into a second configuration to provide a second tip load that is different than the first tip load; further advancing the multi-functional wire guide assembly through the vessel of the patient at the second tip load; and moving a fluid through the open distal end of the elongate tubular housing; exposing the first mandril and the second mandril to the fluid moving through the lumen of the elongate tubular member; wherein the steps of moving the multi-functional wire guide assembly include moving the second mandril relative to the first mandril, which has the portion of the outer surface between opposite ends attached to the inner surface of the elongate tubular housing. - View Dependent Claims (11, 12, 13, 14, 15)
