Magnetic Linear Actuator For Deployable Catheter Tools
Patent Number: WO 2008/150582 Al
Date Filed: December 11, 2008
Country Filed In: WIPO
Product Application: CGCI

Description:

Using the linear forces that are provided by an electromagnetic solenoid applied near the distal end of a medical catheter, various surgical instruments can be actuated or deployed for use in interventional medicine. The linear actuator uses the principles of magnetic repulsion and attraction as a means for moving a bobbin that can be attached to various types of moving components that translate linear movements into the actuation of a tool that is attached to the linear actuator. Using independent solenoid coils movement modality is increased from two possible positions to three.
Field of Use: The Catheter Guidance Control and Imaging (CGCI) system was created to provide physicians the ability to guide a catheter through a patient's body using a robotically-controlled magnetic guidance system. Such a system provides the physician unprecedented accuracy in being able to navigate within the dynamic environment of the patient, create a detailed 3-D mapping, and perform a variety of catheter-based operations with precision control and an ability to return to target at the push of a button. Initial applications for the technology were for the field of Electrophysiology and specifically for the ablation of the heart to treat patients with AFib.
