AI Technical Summary

Technical Problem

Guide catheters face challenges in maintaining position within the anatomy, compatibility with specific medical devices, balancing insertion and bending capabilities, and determining orientation once inserted, which can lead to difficulties in delivering medical devices accurately.

Method used

A pre-shaped guide catheter with proximal and distal curved zones, an enlarged tip, and markings to indicate orientation, designed to specifically engage with and maintain position relative to implantable medical devices, ensuring precise delivery and retrieval of devices.

Benefits of technology

Enhances the ability of guide catheters to maintain position, facilitate precise delivery and retrieval of medical devices, and improve procedural outcomes by aligning with anatomical pathways, reducing the risk of device misalignment and damage.

Abstract

A system for implanting a flow modification device in the heart includes a flow modification device comprising a tubular body having first and second openings located at first and second ends of the tubular body and a reduced diameter section positioned between the first and second openings, and a guide catheter having a flexible elongate shaft having a proximal portion with a coupling for receiving an insertion tool and a distal portion with an enlarged distal tip for preventing the flexible elongate shaft from passing through the flow modification device. A guide catheter for cannulating the coronary sinus from the superior vena cava includes a pre-shaped distal portion with a proximal straight zone, a proximal curved zone extending along a first curved path, a distal straight zone extending along a straight path, and a distal curved zone extending along a second curved path. The guide catheter can have different stiffnesses.
