A catheter pump having a rotor shaft rotatably arranged in the inner catheter for driving an expandable conveyor element provided at the pump head. The conveyor element is rotatably mounted between a. distal hearing point and a proximal bearing point, wherein the outer catheter has a sleeve section on the distal end thereof surrounding the proximal bearing point, and wherein the proximal bearing point can be moved in the axial direction relative to the sleeve section in order to expand the conveyor element, wherein the proximal bearing point comprises a bearing receiver having a rotational bearing point for a rotary head rotationally fixed to the distal end of the rotor shaft, and a force application point at an axial distance to same for a force application section provided at the distal end of the inner catheter for axially moving the proximal bearing points relative to the sleeve section.

Described are methods, systems, and devices for facilitation of intraluminal medical procedures within the neurovasculature including catheters and catheter advancement elements.

Catheters for infusion of cardiovascular fluids into blood are disclosed. The cardiovascular fluid may, for example, comprise water highly supersaturated with a gas such as oxygen. Each catheter comprises one or more capillary tubings (or capillaries) through which a cardiovascular fluid flows. The distal end of each capillary is mounted (e.g., potted) preferably flush with an external surface of a catheter sidewall, while the proximal end of each capillary is in fluid communication with a cardiovascular fluid flowing through the lumen of the catheter. The combination of the catheter shape and the orientation of the distal end of each capillary relative to the longitudinal axis of the catheter provides control over the mixing pattern of the cardiovascular fluid with blood flowing within a vascular space such as an aorta.

A suction pump system for aspirating fluids and other materials from a human body comprises a power source, an aspiration pump, and an electrical motor coupled to the power source and the aspiration pump, wherein the aspiration pump is pulsed at a frequency below 100 Hz.

A medical device comprises a catheter and an aspiration pump. The catheter has a hybrid reinforcement to improve performance characteristics. The aspiration pump is cycled to improve aspiration efficacy.

A ventricular assist device includes a stent for placement within a cardiac artery and arranged for placement, the stent arranged to have an open configuration defining a flow path, a rotor sized to fit within the stent and arranged for percutaneous placement the flow path, the rotor including a surface disposed about a central portion and angled with respect to the flow path and having a first plurality of magnets. A collar is sized for placement about the cardiac artery and includes a stator. A power source is coupled to the stator, and the stator and the rotor are arranged to rotate the rotor about an axis. A timing control module controls a rotational speed of the rotor. Accordingly, the surface of the rotor is arranged to move blood along the flow path in response to rotation of the rotor.

An endovascular catheter has an elongate catheter body having a distal portion, a proximal portion, multiple transition portions and a central lumen extending longitudinally through the catheter body. The catheter has a hybrid reinforcement, an angulated radiopaque marker and an angulated distal tip to improve the catheter's ability to navigate vasculature and to improve clot aspiration.
