Stent introducer apparatus
First Claim
1. A stent introducer apparatus comprising:
- a catheter having a proximal end portion and a distal end portion;
a guide wire movably disposed within the catheter, the guide wire having a proximal end portion and a distal end portion;
a deployable stent, the stent being disposed within the distal end portion of the catheter and being engaged by the distal end portion of the guide wire; and
a handle fixedly connected to the proximal end portion of the guide wire,wherein the stent is deployed by moving the catheter in a proximal direction relative to the guide wire, the proximal end portion of the catheter being engaged by and split by the handle as the catheter is moved in the proximal direction,wherein the handle comprises a first portion and a second portion, the first portion being axially movably connected to the second portion, further wherein the proximal end portion of the catheter is connected to the first portion and the proximal end portion of the guide wire is connected to the second portion, whereby movement of the first portion relative to the second portion causes the proximal end portion of the catheter to be split by the second portion of the handle.

Abstract
A stent introducer apparatus includes a handle with a proximal end and a distal end and having a portion that is coaxially slidable from the distal end to the proximal end and vice versa. A catheter having a proximal end and a distal end is provided with a pair of open end slits each of which defines a tab that is connected to the slidable portion of the handle. A guide wire is disposed within the catheter and has a proximal end and a distal end such that when the slidable portion of the handle is moved from the distal end to the proximal end, the distal end of the guide wire is exposed. The guide wire has a stent carrying portion at its distal end to carry a stent that is deployed when the distal end of the guide wire is exposed.

14. A stent introducer apparatus comprising:
-
a catheter having a proximal end portion and a distal end portion, a pair of tab portions each having a proximal end and a distal end, the distal ends of the tab portions being connected to the proximal end portion of the catheter; a guide wire movably disposed within the catheter, the guide wire having a proximal end portion and a distal end portion; a deployable stent, the stent being disposed within the distal end portion of the catheter and being engaged by the distal end portion of the guide wire; and a handle having a first portion and a second portion, the first portion being axially movably connected to the second portion, the proximal ends of the tab portions being fixedly connected to the first portion of the handle and the proximal end portion of the guide wire being fixedly connected to the second portion of the handle, wherein the second portion of the handle is adapted to engage and split the proximal end portion of the catheter at a location where the distal ends of the tab portions are connected to the proximal end portion of the catheter, and wherein the stent is deployed by moving the first portion of the handle in a proximal direction relative to the second portion of the handle so as to cause the proximal end portion of the catheter to be engaged and split by the second portion of the handle, whereby the catheter is moved in a proximal direction relative to the guide wire. - View Dependent Claims (15, 16, 17, 18)
