CATHETER PUMP WITH PUMP HEAD FOR INSERTION INTO ARTERIAL BLOOD SYSTEM Russian patent published in 2020 - IPC A61M1/10 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment. Disclosed is a catheter pump with a pump head for insertion into an arterial blood system, with an external catheter placed in an external catheter with an internal catheter and rotatably mounted in the internal catheter by a rotary shaft for actuation of a pump head provided for expansion of the delivery element. Feeding element is installed with possibility of rotation between the distal support part and the proximal support part. Outer catheter on its distal end has a sleeve section surrounding the proximal support portion. Proximal support part for expansion of the feeding element is made with possibility of movement in axial direction relative to the sleeve section. Proximal support part includes a support receiving element, which has a rotary support part for rotary shaft rotationally connected to the distal end of the rotor shaft and an axially distal portion of force application for a portion of force application provided at the distal end of the internal catheter for axial movement of the proximal support portion relative to the sleeve portion.

EFFECT: technical result is providing improved proximal support part for catheter pump.
