AI Technical Summary

Technical Problem

Existing implantable devices face challenges in being transported through narrow channels due to their size, and current transmission systems, such as flexible shafts, are prone to wear and require external motors, which are not optimal for lubrication conditions.

Method used

A motor design with a radially compressible and expandable stator and rotor, allowing for axial displacement and reversible deformation, enabling the motor to be compactly transported and expanded at the target location, eliminating the need for external motors and flexible shafts.

Benefits of technology

Enables efficient transport of motors through narrow channels and subsequent expansion for optimal performance, reducing wear and improving lubrication conditions, thus enhancing the usability of implantable devices.

Abstract

The invention relates to a motor with a stator (2, 2') and a rotor (1, 1') that can be driven in an axial direction (4), characterized in that at least one of them, in particular the stator, which has a current-carrying winding arrangement, is radially compressible and expandable.
