Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing robotic catheter-based systems face challenges in navigating complex vasculature due to the need for multiple operators to manage over-the-wire catheters, particularly in tortuous or calcified vasculature, and rapid-exchange catheters lack adequate distal support, complicating procedures like neurovascular intervention, percutaneous coronary intervention, and peripheral vascular intervention.

Innovation Solution

A data capture system that generates profiles based on operator inputs, using sensors to detect motion and load parameters, and a processing unit to convert these parameters into adaptive guidance for robotic systems, enabling single-operator control of elongated medical devices with improved navigation and support.

AI summary

An example data capture system generates profile using captured parameters from a reference operator. The data capture system includes a user interface to receive inputs from a reference operator for operation of one or more elongated medical devices (EMDs); a sensor system to capture parameters associated with the inputs from the reference operator, and a processing unit to generate at least one profile using the captured parameters, the profile being associated with a characteristic of the reference operator.
