Title: Magnetic connector for steerable medical device
Inventor: HAUBERT ZACHARY HAMILTON
IPC: A61M25/01
Filed: 2021-07-07
Abstract: To provide a robot-assisted steerable medical device capable of executing a bending motion.SOLUTION: In a robot-assisted steerable medical device, such as a catheter, a magnetic connector hub is configured to establish mechanical and magnetic connection between a drive wire and an actuator or between multiple pairs of drive wires and actuators in a single insert-and-twist motion. The connector hub creates a magnetic breakaway feature for automatically decoupling the actuator from the drive cable, while the catheter remains attached to the hub. This prevents damage to the catheter when excessive force is applied to the drive wire and enhances safety of treatment to be performed to a patient. When a magnetic breakaway occurs, a system automatically re-engages the catheter so that normal operation can resume. The connection between the drive wire and the actuator can be broken at any point of time in the operation on the basis of threshold force or emergency situations.SELECTED DRAWING: Figure 2
