  • Patent number: 11903865
    Abstract: According to some embodiments of the invention, an anchoring system includes a sleeve having an inner surface defining a first lumen, a first annular sealing mechanism disposed at a proximal end of the sleeve, and a second annular sealing mechanism disposed at a distal end of the sleeve. The anchoring system further includes a pressure tube in fluid connection with an outer surface of the sleeve, a sheath in mechanical connection with the sleeve, the sheath forming a second lumen, the second lumen being in fluid connection with the first lumen, and open-cell foam disposed on the outer surface of the sleeve. Application of negative pressure to the pressure tube causes a seal to form between the first and second annular sealing mechanisms and an inner surface of a tissue cavity. Application of negative pressure to the pressure tube also creates a frictional force that resists displacement of the sleeve.
