Abstract
A system and method for percutaneous ventricular assist devices are provided, where the percutaneous ventricular assist devices include a pump assembly and a cannula assembly. The pump assembly includes one or more connectors at or near a distal end. The cannula assembly includes a cannula and an inflow cage, as well as a mating connector engageable with the connectors of the pump assembly such that the first cannula assembly is attachable to the pump assembly. In various embodiments, the cannula assembly may be fixedly attached or removably attached from the pump assembly.
Claims22
A percutaneous ventricular assist device, comprising:
- a pump assembly having a distal end and proximal end, the pump assembly having one or more connectors at or near the distal end;
- and
- a first cannula assembly including a first cannula, the first cannula assembly having a distal end and a proximal end, the proximal end including one or more mating connectors engageable with the one or more connectors of the pump assembly;
- wherein the first cannula assembly is configured to be attached to the pump assembly by a clinician before a medical procedure.
A kit comprising:
- a pump assembly having one or more connectors at or near a distal portion;
- a first cannula assembly having one or more mating connectors at or near a proximal portion of the first cannula assembly;
- a second cannula assembly having one or more mating connectors at or near a proximal portion of the second cannula assembly, the second cannula assembly being different than the first cannula assembly;
- wherein the one or more mating connectors of first cannula assembly engage with the one or more connector of the pump assembly such that the first cannula assembly is coupled to the pump assembly.
20-55. (canceled)
A percutaneous ventricular assist device, comprising:
- a pump assembly having a distal end and proximal end;
- a first cannula assembly having a first cannula and a sensor, the first cannula assembly having a distal end and a proximal end, the proximal end attached to the pump assembly, the distal end having one or more connectors;
- a second cannula assembly having a second cannula and a first inflow cage, wherein the second cannula includes one or more mating connectors engageable with the one or more connectors of the first cannula assembly such that the second cannula assembly is attachable to the first cannula assembly by a clinician before a medical procedure.
