AI Technical Summary

Technical Problem

Catheter devices face challenges in avoiding tissue damage, maintaining flexibility without kinking, reducing wear and tear, and managing heat generation during high-speed rotation, particularly in blood pumps where friction and heat can lead to material melting and blood protein denaturation.

Method used

A catheter device with a drive shaft cover that includes a distal bearing with a hollow space around the drive shaft, a pliable section for bending, and a heat conducting part to manage heat transfer, ensuring the drive shaft remains flexible and prevents tissue entanglement while reducing wear and heat-related damage.

Benefits of technology

The solution effectively prevents tissue damage, maintains drive shaft flexibility, reduces wear and tear, and manages heat transfer, enhancing the longevity and safety of the catheter device by minimizing friction and heat-related issues.

Abstract

The invention relates to a catheter device (1), comprising a drive shaft (4) extending from a driving region (16) of the catheter device (1) to a distal end region (8) of the catheter device (1), a rotor (2) which is attached to the drive shaft (4) in the distal end region (8) and a distal bearing (9) for bearing a distal end of the drive shaft (4). The distal bearing comprises a drive shaft cover (11) which is configured to cover a section of the drive shaft (4) extending distally of the rotor (2). On a distal side of the rotor (2), a radially inner part of the rotor (2) is recessed with respect to radially outer parts of the rotor (2) to form a hollow space (2.3) surrounding the drive shaft (4), wherein a proximal end of the drive shaft cover (11) lies in said hollow space (2.3).
