Abstract
A suction device includes a suction cup having a vacuum inlet for connection to a vacuum source. The suction cup has a wall defining a cavity that is in fluid communication with the vacuum inlet and an engagement surface for engaging a tissue surface. The suction cup is formed of a material that minimizes injury to the tissue surface contacted by the engagement surface and tissue captured when the vacuum is applied and permits the captured tissue to be perfused during use of the suction device.
Claims8
A suction device for applying vacuum to a tissue surface, the suction device comprising a suction cup portion having a vacuum inlet, the suction cup portion having a wall defining a cavity in fluid communication with the vacuum inlet and an engagement surface for engaging the tissue surface, the suction cup portion being formed of a material having a durometer of less than 40 Shore A.
A suction device for applying vacuum to a tissue surface, the suction device comprising a suction cup portion having a vacuum inlet, the suction cup portion having a wall defining a cavity in fluid communication with the vacuum inlet and an engagement surface for engaging the tissue surface, the suction cup portion being configured to have a controlled leak rate of approximately between 3 and 5 mm Hg/minute.
A method of positioning a heart with a suction device, comprising the steps of:
- providing a suction device comprising a suction cup portion having a vacuum inlet, the suction cup portion having a wall defining a cavity in fluid communication with the vacuum inlet and an engagement surface, the suction cup portion being formed of a material having a durometer of less than 40 Shore A;
- contacting an apex of the heart with the engagement surface of the cup portion;
- supplying a vacuum to the vacuum inlet to capture heart tissue within the suction device;
- conforming a substantial portion of the wall of the suction device to a portion of the apex of the heart;
- and
- repositioning the heart using the suction device while permitting substantial perfusion of the heart tissue captured within the suction device.
