Surgical method and system for performing the same

A system for repairing biological tissue, the system comprising:

• a catheter having a lumen in communication with a cooling subsystem;
• a guide having a cooling surface configured to be placed against a tissue surface of the biological tissue;
• and
• a driver configured to releasably attach a helicoidal member, the helicoidal member configured to reshape at least a portion of the biological tissue by rotating a distal end of the helicoidal member in a helical direction such that the distal end penetrates into the biological tissue, the driver being operative for rotating the helicoidal member to (i) allow the helicoidal member to advance along the guide and penetrate into the biological tissue and (ii) be withdrawn out of the biological tissue without removing the biological tissue;
• wherein the cooling subsystem is configured for cooling the cooling surface to a predetermined temperature, the predetermined temperature being low enough to cause adhesion between the cooling surface and the tissue surface.

A system for repairing biological tissue, the system comprising:

• a guide having an adhering surface configured to be placed against a tissue surface of the biological tissue;
• a driver having a lock configured to releasably attach an anchor configured to penetrate in at least a portion of the biological tissue, the driver being operative for advancing the anchor along the guide to penetrate into the at least the portion of the biological tissue by rotating a distal end of the anchor in a helical direction such that the distal end penetrates into the biological tissue, wherein the driver is also operative to withdraw the anchor out of the biological tissue without removing the biological tissue;
• and
• a tissue adherence subsystem operatively coupled to the guide to selectively cause adhesion between the adhering surface and the tissue surface, wherein the adhesion is caused by cooling the adhering surface.
