IPC: A61M1/10

Abstract: Devices and methods for assisting blood flow are provided. The device includes a housing with an inlet and an outlet, and a fluid barrier separating the housing into a first section containing the inlet and outlet, and a second section. The device also includes an impeller shaft coupled to an impeller and a first magnet in the first section of the housing, and a drive shaft coupled to a second magnet in the second section of the housing. The first and second magnets are arranged such that rotation of the drive shaft rotates the second magnet causing rotation of the first magnet, which drives the impeller.

Abstract: Polypectomy devices and methods for making and using polypectomy devices are disclosed. An example polypectomy device may include an elongate sheath having a proximal end region and a distal end region. A shaft may be slidably disposed within the sheath. A handle may be coupled to the proximal end region of the sheath. The handle may be designed to axially shift the shaft relative to the sheath. A snare may be coupled to the shaft. The snare may include a first region, a traction region, and a distal tip region. The first region may have a non-circular cross-sectional shape. The traction region may include a plurality of traction members. At a position between two adjacent traction members the snare may have a reduced cross-sectional area relative to the first region. The distal tip region may have a circular cross-sectional shape.

Abstract: A percutaneous circulatory support device includes a housing having an inlet and an outlet. A shaft is rotatably fixed relative to the housing. An impeller is disposed within the housing and is rotatably supported by the shaft. The impeller is configured to rotate relative to the shaft and the housing to cause blood to flow into the inlet, through the housing, and out of the outlet. A keeper is coupled to the shaft distally relative to the impeller, and the keeper inhibits axial motion of the impeller relative to the shaft.
