Patent number: 11964144Abstract: 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.Type: GrantFiled: February 12, 2021Date of Patent: April 23, 2024Assignee: TC1 LLCInventors: Richard L.
