Abstract

A variable scale medical implant deployment device comprising a variable inner diameter scale sleeve insert is provided. Also described are kits containing the variable scale medical implant deployment device and methods for deploying a medical implant into a body lumen using a variable scale medical implant deployment device.

Claims

1. A method for implanting a medical implant into a body lumen of a subject in need thereof, comprising:

attaching a catheter comprising a medical implant at or near its distal end to a variable scale medical implant deployment device, comprising;

a variable inner diameter (ID) scale sleeve insert,

a base handle comprising a base tubular member with a central longitudinal lumen, a proximal palm rest handle and a deployment extension, and

a first tubular member having a first tubular body with a distal floating luer fitting and a first handle, wherein the base tubular member has a proximal end and a distal end,

wherein the variable ID scale sleeve insert is inserted into central longitudinal lumen of the base tubular member from the proximal end of the base tubular member, and wherein the first tubular member slides over the base tubular member of the base handle from the distal end of the base tubular member,

establishing an entry portal,

introducing the distal end of the catheter through the entry portal,

advancing the catheter to the desired body lumen such that the medical implant is located in the desired location, and

deploying the medical implant.

2. The method of claim 1, wherein medical implant is a stent.

3. The method of claim 2, wherein the stent is a self-expanding stent.
