Abstract: An intravascular blood pump (1) comprises a pumping device and a catheter (5). The pumping device comprises a drive shaft (12), a rotor (10) located at a distal end of the drive shaft (5), a housing (11), in which the rotor (10) is housed, and a distal bearing (14) for rotatably supporting a distal end of the rotor (10). The distal bearing (14) comprises a static support member (18), which protrudes into or up against the distal end of the rotor (10). The rotor (10) and housing (11) may be expandable, and the pin (19) may have a sufficient length to prevent disengagement of the pin (19) from the distal end of the rotor (10) when the rotor (10) and the housing (11) are in a collapsed state.

Abstract: A method of manufacturing a cannula (4) for an intravascular blood pump comprises the steps of forming a first axial section (13) and a second axial section (15) of an elongate tubular body of the cannula (4) by dispensing a first liquid material and a second liquid material, respectively, onto a mandrel (7) by means of at least one dispenser (8). The mandrel (7) is rotated and the dispenser (8) moves relative to the mandrel (7) in an axial direction during dispensing of the liquid materials. The first and second axial sections (13,15) are formed so as to have different bending stiffnesses. The first and second liquid materials are dispensed onto the mandrel (7) such that the first and second liquid materials blend into each other to form a smooth transition area (14).

Abstract: A sheath ( 10) for producing a fully sealed access to the interior of a vessel of an animal or human body comprises a base sheath (20) having a tubular body defining a pass-through channel (22). The base sheath (20) is adapted to be inserted into the vessel through a vessel aperture. A wall of the tubular body of the base sheath has a through channel (27). This channel extends in the wall from the distal end (20a) towards the proximal end (20b). The channel (27) can be present separately from the pass-through channel (22) of the base sheath or can form a sideways extension of the pass-through channel (22), at least at the distal end.. Such through channel (27) is adapted to conduct blood from the vessel to the proximal end of the sheath when the sheath has been inserted into a vessel.

Abstract: A method and an apparatus for use in estimating blood flow in an intravascular blood pump comprise retrieving reference data from a set of reference data obtained in a test environment. The set of reference data comprises, for at least one motor speed at different pump loads, including a first pump load, both a reference motor current (I) of a motor driving the blood pump and an amount of fluid flow through the blood pump. After placement of the blood pump in the patient, a patient-specific motor current for said motor speed at said first pump load is measured, and a motor current deviation value (ΔΙ) is calculated from the reference motor current (I) at said first pump load and patient-specific motor current. Finally, the motor current deviation value ΔΙ is used for estimating a patient-specific blood flow amount through the blood pump.
