Abstract
A rotor for a fluid pump which is flexible in handling and compressible. A conveying blade has at least two struts and a membrane spanned between them in the expanded state. At least one of the struts has at least one joint which enables an angling in a first direction in a first movement plane and bounds an overelongation beyond an elongation angle in an opposite second direction.
Claims19
A catheter having a distal end and a proximal end, the catheter comprising:
- a rotor disposed at the distal end of the catheter, the rotor comprising a hub and a conveying blade for a radially compressible and expandable rotor of a fluid pump, the conveying blade having at least two struts and a membrane held thereby in an expanded state;
- wherein at least one of the two struts has a first section connected to the hub, and a second section rotatably connected to the first section by at least one joint, wherein the joint permits angling of the second section in a first movement plane, wherein the angling of the second section relative to being collinear with the first section is more limited in a second direction than in a first direction, wherein the first direction is the direction of rotation of the blade during operation;
- and
- wherein the joint bounds angling of the second section beyond an elongation angle in the second direction.
