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 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.

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.
