Systems, apparatuses, and methods for cardiovascular cutting devices and valves

A method comprising:

• positioning a first end of a tube against a cardiovascular organ, the tube comprising a first valve;
• inserting a cutting member into the tube;
• opening the first valve to allow the cutting member to pass through the first valve to the cardiovascular organ;
• cutting a first section of tissue out of the cardiovascular organ with the cutting member;
• retracting the cutting member from the tube;
• closing the first valve after the cutting member is retracted through the first valve.

A system comprising:

• a tube with a first end dimensioned to be positioned against a coring site of a cardiovascular organ;
• a cardiovascular coring device adapted to core an opening in the cardiovascular organ, the cardiovascular coring device comprising:
• a cutting member adapted to core the opening in the cardiovascular organ by cutting out a section of cardiovascular organ tissue;
• a tissue retraction member adapted to remove the section of cardiovascular organ tissue from the cardiovascular organ;
• a first valve positioned inside the tube, the first valve being adapted to open to allow the cardiovascular coring device to pass through the first valve to the coring site, the first valve being adapted to close after the cardiovascular coring device is retracted through the first valve, the first valve being adapted to seal the cardiovascular coring device to the tube when the cardiovascular coring device is positioned within the tube;
• a second valve positioned inside the cutting member, the second valve being adapted to open to allow the tissue retraction member to pass through the second valve to the coring site, the second valve being adapted to close after the tissue retraction member is retracted through the second valve.

A method comprising:

• positioning a cutting member against a cardiovascular organ, the cutting member comprising a valve;
• opening the valve to allow a tissue retraction member to pass through the valve to the cardiovascular organ;
• anchoring the tissue retraction member in a first section of tissue of the cardiovascular organ;
• cutting the first section of tissue out of the cardiovascular organ with the cutting member;
• retracting the first section of tissue out of the cardiovascular organ by retracting the tissue retraction member;
• closing the valve after the tissue retraction member is retracted through the valve.
