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 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.

2. The device of claim 1, further comprising:

a second tubular member having a second tubular body with a distal floating luer fitting and a second handle, wherein the second tubular body slides over the first tubular body.

3. The device of claim 1, wherein the variable ID scale sleeve insert is a replaceable insert and has an external diameter that allows the variable ID scale sleeve insert fits securely within the central longitudinal lumen of the base handle.

4. The device of claim 1, wherein the variable ID scale sleeve insert comprises an internal channel with an inner diameter.

5. The device of claim 4, wherein the variable ID scale sleeve is made of a rigid material.

6. The device of claim 1, wherein the variable ID scale sleeve insert further comprises rigid support tube that is inserted into the internal channel of the variable ID scale sleeve, wherein the rigid support tube comprises a tube body and an internal lumen.

7. The device of claim 6, wherein the internal lumen of the rigid support has a diameter that accommodates a catheter.

8. The device of claim 6, wherein the internal lumen of the rigid support has a diameter in the range of 1-20 in French scale.

9. The device of claim 8, wherein the internal lumen of the rigid support has a diameter in the range of 3-15 in French scale.

10. The device of claim 1, wherein the variable ID scale sleeve insert is secured in the central longitudinal lumen of the base handle by an end cap at a proximal end of the central longitudinal lumen.

11. The device of claim 1, further comprising a safety tab that prevents premature deployment of the medical implant.

12. The device of claim 1, wherein the medical implant is a stent.

13. A kit comprising variable scale medical implant deployment device of claim 1.

14. The kit of claim 13, further comprising a catheter.

15. The kit of claim 13, further comprising a guide wire.

16. The kit of claim 13, further comprising a plurality of variable ID scale sleeve inserts for insertion into the variable scale stent deployment device.

17. The kit of claim 13, further comprising one or more medical implants for insertion into a body lumen.

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

attaching a catheter of the desired scale size to the variable scale medical implant deployment device of claim 1, wherein the catheter comprises an medical implant at or near its distal end,

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.

19. The method of claim 18, wherein medical implant is a stent.

20. The method of claim 19, wherein the stent is a self-expanding stent.
