Abstract: A catheter pump is disclosed. The catheter pump can include an impeller and a catheter body having a lumen therethrough. The catheter pump can also include a drive shaft disposed inside the catheter body. A motor assembly can include a chamber. The motor assembly can include a rotor disposed in the at least a portion of the chamber, the rotor mechanically coupled with a proximal portion of the drive shaft such that rotation of the rotor causes the drive shaft to rotate. The motor assembly can also comprise a stator assembly disposed about the rotor. The motor assembly can also include a heat exchanger disposed about the stator assembly, the heat exchanger may be configured to direct heat radially outward away from the stator assembly, the rotor, and the chamber.

Abstract: A catheter pump is disclosed. The catheter pump can include an impeller and a catheter body having a lumen in which waste fluid flows proximally therethrough during operation of the catheter pump. The catheter pump can also include a drive shaft disposed inside the catheter body. A motor assembly can include a chamber. The motor assembly can include a rotor disposed in the at least a portion of the chamber, the rotor mechanically coupled with a proximal portion of the drive shaft such that rotation of the rotor causes the drive shaft to rotate, the rotor including a longitudinal rotor lumen therethrough. The motor assembly can also comprise a stator assembly disposed about the rotor. During operation of the catheter pump, the waste fluid flows from the lumen into the chamber such that at least a portion of the waste fluid flows proximally through the longitudinal rotor lumen.

Abstract: A catheter pump is disclosed herein. The catheter pump can include a catheter assembly that comprises a drive shaft and an impeller coupled to a distal end of the drive shaft. A driven assembly can be coupled to a proximal end of the drive shaft within a driven assembly housing. The catheter pump can also include a drive system that comprises a motor and a drive magnet coupled to an output shaft of the motor. The drive system can include a drive assembly housing having at least one magnet therein. Further, a securement device can be configured to prevent disengagement of the driven assembly housing from the drive assembly housing during operation of the pump.

Abstract: A multi-axis system (30) for positioning a workpiece measuring sensor (54) on a metrology machine. Preferably, each sensor is positionable via a system comprising movement along and/or about at least linear directions/axes (X, Z, A, B) so as to control linear and/or rotational movement of a sensor automatically to a predetermined position without operator intervention. The multi-axis positioning system allows faster setup times when a workpiece or tooling on a machine is changed.

Abstract: A method and machine comprising at least one non-contact sensor (52) on a functional testing platform (50) for workpiece inspection and/or measurement. The inclusion of at least one non-contact sensor on the functional testing platform results in the combination of two machine platforms into a single machine and provides the user with measurement characteristics of both methods, functional and analytical, saving significant cycle time and significant space.

Abstract: A thermoelectric module (10) which is adapted to selectively heat or cool the inside of a container includes an exterior heat exchanger (51) having a plurality of spaced and generally parallel undulating fins (52). An exterior fan (31) is positioned adjacent to the exterior heat exchanger (51) and is adapted to move air from the outside of the container through the spaces between the fins (52) of the exterior heat exchanger (51). An interior heat exchanger (54) has a plurality of spaced and generally parallel undulating fins (55). An interior fan (42) is positioned adjacent to the interior heat exchanger (54) and is adapted to move air from the inside of the container through the spaces between the fins (55) of the interior heat exchanger (54). A motor (28) drives the fans (31, 42) and is cooled by air drawn in through apertures (34) in the hub (32) of the exterior fan (31).
