Abstract: An example renal support pump includes a renal support device including an outer catheter shaft having a longitudinal axis and a distal end region coupled to a renal pump assembly, wherein the renal pump assembly includes a frame and an impeller assembly, wherein the impeller assembly is disposed within the frame, and wherein the impeller assembly is configured to rotate relative to the frame about the longitudinal axis of the catheter shaft.

Abstract: A percutaneous circulatory support device includes an impeller housing configured to receive a guidewire during delivery of the percutaneous circulatory support device to a patient. A catheter is coupled to a proximal end portion of the impeller housing, the catheter including a lumen being configured to receive the guidewire during delivery of the percutaneous circulatory support device to the patient. An impeller is rotatable in the impeller housing after delivery of the percutaneous circulatory support device to the patient to cause blood to flow through the percutaneous circulatory support device.

Abstract: A percutaneous circulatory support device includes an impeller portion having a proximal end portion and an impeller being rotatable to cause blood to flow through the percutaneous circulatory support device. A catheter is coupled to the proximal end portion, and the catheter includes a preformed curve.

Abstract: The present invention relates generally to medical devices and, in particular, to an introducer sheath that includes a shaft including a tubular portion, an expandable portion coupled to the tubular portion and a longitudinal axis. Additionally, the expandable portion includes a first pair of leaflets and a second pair of leaflets and both the first pair of leaflets and the second pair of leaflets extend along the longitudinal axis. Additionally, the second pair of leaflets are spaced radially inward of an inner surface of the first pair of leaflets and the expandable portion is designed to shift between a first configuration and a second radially expanded configuration.
