Abstract: Sensors for catheter pumps are disclosed herein. The catheter pump can include a catheter assembly comprising a catheter and a cannula coupled to a distal portion of the catheter. The cannula can have a proximal port for permitting the flow of blood therethrough. The catheter assembly can include a sensor to be disposed near the proximal port. A processing unit can be programmed to process a signal detected by the sensor. The processing unit can comprise a computer-readable set of rules to evaluate the signal to determine a position of the cannula relative to an aortic valve of a patient.

Abstract: A catheter pump assembly is provided that includes an elongate polymeric catheter body, a cannula, and a tubular interface. The elongate polymeric catheter body has a proximal end and a distal end. The cannula has an expandable portion disposed distally of the elongate polymeric catheter body. The cannula can also have another tubular portion that is proximal to the distal portion. The tubular interface has an outer surface configured to be joined to the tubular portion of the cannula and an inner surface. The inner surface is disposed over the distal end of the elongate polymeric catheter body. The tubular interface has a plurality of transverse channels extending outward from the inner surface of the tubular interface. An outer surface of the elongate polymeric catheter body projects into the transverse channels to mechanically integrate the elongate polymeric catheter body with the tubular interface.

Abstract: A catheter pump includes a catheter body having at least one lumen therethrough, and comprising a distal end and a proximal end. An expandable impeller assembly includes an expandable impeller and an expandable cannula coupled to the distal end of the catheter body and housing the expandable impeller, the expandable cannula comprising a substantially straight segment having a distal inlet and a proximal outlet, the substantially straight segment configured to straddle an aortic valve. The catheter body comprises a proximal vessel contact zone and a distal vessel contact zone that are each proximal to the substantially straight segment, the proximal vessel contact zone and distal vessel contact zone configured to provide a force against an aortic arch to stabilize the expandable impeller assembly across the aortic valve.

Abstract: In one embodiment, a catheter pump assembly is disclosed. The catheter pump assembly can include an impeller assembly. A catheter body can be coupled with the proximal end of the impeller assembly, the catheter body having a reduced stiffness section disposed proximally of the impeller assembly. A sheath assembly can be configured to be translate over the catheter body relative to the impeller assembly from an impeller assembly delivery position to an impeller assembly deployment position. When the sheath assembly is in the impeller assembly deployment position, a reduction in stiffness is provided between the distal end of the sheath assembly and the impeller assembly.

Abstract: A method of coupling components of a catheter pump assembly includes providing an elongate polymeric tubular body having a proximal end and a distal end, and also providing a metallic tubular body having a proximal portion and a distal portion. The method further includes positioning a mechanical interface having a first interface zone and a second interface zone such that the first interface zone is disposed over a portion of the elongate polymeric tubular body adjacent to the distal end thereof. The method also includes flowing the polymer into the first interface zone, whereby the elongate polymeric tubular body becomes joined with the first interface zone of the mechanical interface, and coupling the metallic tubular body with the second interface zone of the mechanical interface.
