ABSTRACT:
In one embodiment, there is disclosed a device adapted to be used for percutaneous minimally invasive heart surgery including a catheter having a proximal end and a distal end adapted to be fed through a blood vessel, a pump associated with the distal end of the catheter, and a tool associated with the distal end of the catheter. The tool is adapted to be used for percutaneous minimally invasive heart surgery. Examples of the tools include a tool for excising natural tissue, a tool for excising a natural valve, and anthretomy device, a prosthetic valve delivery system, a balloon catheter, a knife, a stapler, and a screwdriver. The pump is used for maintaining blood flow around the site of the heart surgery while the surgery is taking place without the use of cardiopulmonary bypass.
