Abstract
Example circulatory support devices are disclosed herein. An example percutaneous circulatory support device includes a blood pump including a pump housing having a distal end region and a proximal end region. Further, the circulatory support device includes a blood inlet positioned along the distal end region, a blood outlet positioned along the proximal end region and a pump scaffold positioned within the pump housing. Further, the pump scaffold is configured to draw blood into the pump inlet and pump blood out of the blood outlet. Further, the pump housing and the pump scaffold are configured to shift between a collapsed configuration and an expanded configuration.
Claims20
A percutaneous circulatory support device, comprising:
- a blood pump including a pump housing having a distal end region and a proximal end region;
- a blood inlet positioned along the distal end region;
- a blood outlet positioned along the proximal end region;
- and
- a pump scaffold positioned within the pump housing;
- wherein the pump scaffold is configured to draw blood into the pump inlet and pump blood out of the blood outlet;
- wherein the pump housing and the pump scaffold are configured to shift between a collapsed configuration and an expanded configuration.
A percutaneous circulatory support device system, comprising:
- a console including a processor;
- a cardiac pump including a controller coupled to the console, wherein the cardiac pump includes a pump housing having a distal end region and a proximal end region;
- a blood inlet positioned along the distal end region;
- a blood outlet positioned along the proximal end region;
- and
- a pump scaffold positioned within the pump housing;
- wherein the pump scaffold is configured to draw blood into the pump inlet and pump blood out of the blood outlet;
- wherein the pump housing and the pump scaffold are configured to shift between a collapsed configuration and an expanded configuration.
A percutaneous circulatory support device, comprising:
- a catheter shaft;
- a blood pump positioned at a distal end region of the catheter shaft, the blood pump including a pump housing having a distal end region and a proximal end region;
- a blood inlet positioned along the distal end region;
- a blood outlet positioned along the proximal end region;
- a pump scaffold positioned within the pump housing, the pump scaffold including a plurality of pumping regions;
- and
- a drive shaft coupled to the pump scaffold;
- wherein the drive shaft is configured to cyclically compress and extend the pump scaffold;
- wherein cyclically compressing and extending the pump scaffold draws blood into the pump inlet and pumps blood out of the blood outlet.
