Tissue stabilization and repair device
A device includes an elongated cannula with an opening positioned at its distal end. A tissue engagement structure is affixed proximate the distal end of the cannula and surrounds the opening. The tissue engagement structure includes a tissue engaging portion to engage and control tissue. An adhesive is dispensed through the cannula opening to repair tissue.
1. A tissue stabilization and repair device, comprising:
a single-piece elongated cannula extending from a proximal end to a beveled tip at a distal end and
defining a lumen including an elongated opening at the distal end; and
a tissue engagement structure extending distally beyond the opening and including a base portion located distal the distal end of the cannula, a tissue engaging portion extending from the base portion, and two opposing legs extending from the base portion, wherein the two opposing legs are directly affixed to the cannula proximate the distal end, and further wherein the opening is positioned between the legs;
wherein the device is configured such that a point of attachment of the legs with the cannula is longitudinally fixed relative to the beveled tip.
2. The device of claim 1 , wherein the tissue engaging portion includes a plurality of teeth.
3. The device of claim 1 , wherein the tissue engaging portion deflects relative to the distal end of the cannula upon a force being applied to the tissue engaging portion.
4. The device of claim 1 , further comprising an adhesive positioned within the lumen.
5. The device of claim 1 , wherein the base portion is substantially planar and is positioned between the opening and the tissue engaging portion.
6. The device of claim 1 , wherein the legs can flex relative to the tissue engaging portion.
7. The device of claim 1 , wherein the cannula is rotatably coupled to the legs.
8. The device of claim 1 , wherein the device is configured to be inserted within a sinus cavity.
9. The device of claim 1 , wherein the base portion terminates at opposing, leading and trailing ends, and further wherein the leading end defines a most-distal edge of the base portion, and even further wherein the leading end and the trailing end are both distally spaced from the distal end of the cannula.
