AI Technical Summary

Benefits of technology

The present patent relates to a catheter for deploying an implantable medical device and an advancing device for use with the catheter. The catheter has a stable zone at its distal end, a protection zone, a flexibility zone, a pushability zone, and a strain relief area. The catheter is designed to have a flexibility index of less than 3000 mN in the protection zone, less than 3500 mN in the flexibility zone, less than 4500 mN in the pushability zone, and less than 6000 mN in the strain relief area. The advancing device includes a base member and a deployment extension with two tubular members that can be moved longitudinally over the deployment extension to deploy the implantable medical device. The technical effects of the invention include improved flexibility and pushability of the catheter, as well as improved maneuverability and accuracy in device deployment.

Problems solved by technology

However, handling the imaging modality, introduction, and access equipment, and the delivery catheter can often be a clumsy process when using multiple devices especially where by the two devices easily disassociate from each other.
Moreover, since many delivery catheters, for one reason or another, cannot be adequately managed with one hand, additional personnel are required when handling the scope and the delivery catheter.

Deployment of an Implantable Medical Device

[0092]An introducer sheath is inserted in an appropriate site in order to gain access to a vessel or lumen.

[0093]A guide wire is inserted through the introducer sheath and advanced through the vessel or lumen to span the area where the implantable medical device is to be deployed.

[0094]The tip 41 of the catheter device 40 is advanced onto the guide wire and the catheter device 40 is advanced through the introducer sheath into the vessel or lumen. The catheter device 40 is advanced through the vessel or lumen such that the stabilization zone 42 is advanced beyond the deployment site and the implantable medical device on the protection zone 43 is directly within the deployment site.

[0095]The protective sheath is withdrawn by pulling handle 24 toward base handle 11, thereby exposing the implantable medical device at the deployment site.

[0096]The implantable medical device is deployed at the site by pulling handle 34 towards handle 24 and base ...

Abstract

A system for deploying an implantable medical device into a body lumen is disclosed. The system comprises a catheter having functional zones for stability, protection, flexibility, trackability and pushability. The system further comprises a device for deploying an implantable medical device with the catheter. A method for deploying an implantable medical device into a body lumen using the system is also disclosed.

Description

[0001]This application Continuation of application Ser. No. 15 / 227,608, filed on Aug. 3, 2016, which is a Continuation of application Ser. No. 13 / 952,334, filed on Jul. 26, 2013, now U.S. Pat. No. 9,414,943, which is a Continuation of application Ser. No. 13 / 486,249, filed on Jun. 1, 2012. The entirety of the aforementioned applications is incorporated herein by reference.FIELD[0002]The present application relates generally to medical devices and, in particular, to a delivery system and method for introducing implantable medical devices into a body cavity.BACKGROUND[0003]Implants may be placed in the human body for a variety of reasons. For example, stents are placed in a number of different body lumens such as blood vessels and biliary ducts; vena cava filters are implanted in the vena cava to catch thrombus sloughed off from other sites within the body; and vaso-occlusive devices are used for the treatment of intravascular aneurysms.[0004]Interventional practitioners, regardless o...
