Abstract
A device and method for performing anastomosis is described. In one embodiment according to the present invention, the device comprises a ring that has a plurality of pins extending from various locations on the ring. During a procedure, the pins are passed through portions of tissue and the ring is everted or radially flipped inside out to connect the tissues together.
Claims15
A method of connecting two biological passages within a patient, comprising:
- inserting pins of a connection device through tissue in proximity of a first opening of a first biological structure;
- inserting pins of the connection device through tissue in proximity of a second opening of a second biological structure;
- everting a ring of the connection device so as to change an orientation of the pins such that the ring and the pins of the connection device conform to a tubular shape and thereby press the tissue in proximity of the first opening and the second opening against each other.
A method of connecting two biological passages within a patient, comprising:
- piercing tissue around an opening of a first biological passage with pins extending from a connecting ring;
- positioning distal ends of the pins of the connecting ring into a second biological passage;
- and
- radially everting the connecting ring to cause the pins to pierce tissue of the second biological passage such that the connecting ring and the pins conform to a tubular shape so as to press the tissue of the first biological passage and the tissue of the second biological passage against each other.
1 more element
A method of connecting two biological passages within a patient, comprising:
- everting a connecting ring from a first position, in which a plurality of pins on the connecting ring are positioned in a first direction, to a second position in which the plurality of pins on the connecting ring are positioned in a second direction;
- wherein the everting of the connecting ring connects the two biological passages together when the connecting ring and the pins conform to a tubular shape.
