Abstract: Some embodiments of percutaneous ventricular assist devices have a two-part design that includes a housing component and a separately deployable rotatable inner catheter component. The housing component can include an expandable pump housing. The inner catheter can include an expandable pump impeller and an associated flexible drive shaft. The drive shaft can be coupled to a motor located external to the patient. The motor can rotate the drive shaft to spin the pump impeller inside of the pump housing, causing blood to be pumped within the patient. In some embodiments, the pump impeller is inflatable or self-expandable. The two-part percutaneous ventricular assist devices with inflatable or self-expandable pump impellers are designed to have very small delivery profiles. Accordingly, various deployment modalities, including radial artery deployment, are practicable using the two-part percutaneous ventricular assist devices described herein.

Abstract: A rotor for a pump has a housing and a rotor, and has at least one blade. The rotor is able to be actuated to rotate about an axis of rotation in order to convey a fluid in the axial or radial direction, and the rotor is able to be deformed in the radial direction between a first, radially compressed state and a second, radially expanded state. At a maximum speed of rotation of the rotor at which the power of the pump is at a maximum, the blade is essentially radially oriented, and/or the rotor has its maximum diameter.

Abstract: An improved system for supporting (e.g., localization and/or positioning of) intravascular devices discussed herein provides for example a multi-element arrangement. A set of struts optionally projects from the intravascular device and contacts the vessel walls. The localization and positioning of the pump may be provided by the struts and/or by use of a tether opposing a propulsive force to ensure localization.

Abstract: A connection system for an implantable blood pump including a pump housing having an impeller disposed therein and a motor housing including a motor disposed therein, the motor housing spaced a distance from the pump housing. A flexible outer sheath couples the pump housing to the motor housing, the outer sheath defining a maximum total length between 7 and 10 centimeters. An inner shaft is coaxial with the outer sheath and couples the motor to the impeller.

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