Abstract: A catheter pump system includes a catheter assembly having a proximal end, a distal end, and an elongate body extending therebetween, the elongate body defining at least an inner lumen; a motor assembly comprising a shaft assembly extending at least partially within the elongate body of the catheter assembly, the shaft assembly configured to rotate about an axis; a flow diverter housing defining a chamber and a fluid pathway through which a proximally-conveyed fluid flows, wherein the shaft assembly extends outward from the chamber into the inner lumen of the elongate body; and a seal mounted to and extending around the shaft assembly, the seal configured to inhibit fluid within the elongate body of the catheter assembly from entering the chamber at least about an outer periphery of the shaft assembly.

Abstract: A catheter pump system includes a catheter assembly having a proximal end, a distal end, and an elongate body extending therebetween. The catheter pump system also includes a motor assembly including a shaft assembly extending at least partially within the elongate body of the catheter assembly. The shaft assembly is configured to rotate about an axis. The catheter pump system further includes a flow diverter housing defining a chamber and a fluid pathway through which a proximally-conveyed fluid flows. The shaft assembly extends outward from the chamber into an inner lumen of the elongate body. The catheter pump system also includes a seal configured to extend around and engage the shaft assembly to inhibit fluid within the elongate body of the catheter assembly from entering the chamber at least about an outer periphery of the shaft assembly.

Abstract: A catheter pump system includes a shaft assembly, an impeller coupled to a distal portion of the shaft assembly, and a motor assembly coupled to a proximal portion of the shaft assembly. The motor assembly is configured to drive the impeller via the shaft assembly. The motor assembly includes a rotor, a stator disposed radially outward of the rotor, and a rotor chamber disposed radially between the stator and the rotor. The rotor chamber at least partially encloses the rotor. The rotor chamber is at least partially filled with a lubricant to reduce a friction of the rotor during rotation thereof.

Abstract: A tissue interface module has an applicator chamber on a proximal side of the tissue interface module and a tissue acquisition chamber on a distal side of the tissue interface module. The applicator chamber may include: an opening adapted to receive the applicator; an attachment mechanism positioned in the applicator chamber and adapted to attach the tissue interface module to the applicator; a sealing member positioned at a proximal side of the applicator chamber; and a vacuum interface positioned at a proximal side of the applicator chamber and adapted to receive a vacuum inlet positioned on a distal end of the applicator. The invention also includes corresponding methods.

Abstract: Systems, methods and devices for creating an effect using microwave energy to specified tissue are disclosed herein. A system for the application of microwave energy to a tissue can include, in some embodiments, a signal generator adapted to generate a microwave signal having predetermined characteristics, an applicator connected to the generator and adapted to apply microwave energy to tissue, the applicator comprising one or more microwave antennas and a tissue interface, a vacuum source connected to the tissue interface, a cooling source connected to said tissue interface, and a controller adapted to control the signal generator, the vacuum source, and the coolant source. The tissue may include a first layer and a second layer, the second layer below the first layer, and the controller is configured such that the system delivers energy such that a peak power loss density profile is created in the second layer.
