Compressible and expandable turbine blade for a fluid pump

摘要

The blade (2) has two lamellae (3-5) arranged adjacently. Each lamellae is formed with a web extending in radial direction of a rotor shaft (1). The adjacent lamellae are adapted to form a seal on an overlapping lip. The lamellae are pivotable relative to axis of a rotation (1a) of a rotor and movable relative to each other and abut against each other in an expanded state so as to form a continuous blade surface. The adjacent lamellae are connected to each other by a flexible element e.g. strip and membrane. Independent claims are also included for the following: (1) a method for the producing a blade (2) a catheter pump for introduction into human vessels comprising a rotor with a blade.
