Slotted anchor device
A slotted anchor that secures to a connector as part of an anchor assembly is disclosed. The slotted anchor includes a pair of spaced apart prongs which join together at a slot inception. The prongs are shaped and sized of a configuration and of a rigidity to substantially prevent deflection of the prongs. The prongs include inwardly facing protrusions that are configured to capture and deform the connector between the protrusions and prevent the connector from disengaging from the slotted anchor once engaged.
1. An anchor assembly for applying retractive pressure to tissue, the anchor assembly comprising:
a distal anchor, wherein the distal anchor includes a head portion that is connected to a tail portion via a connecting mid-section portion, wherein the tail portion is oriented transverse to the head portion;
a suture, wherein the suture is attachable and tensioned to the distal anchor; and
a slotted proximal anchor for securing a suture as part of a proximal end of an anchor assembly, the slotted anchor device comprising:
a tubular back end having a partially flattened cross-section; and
at least two pairs of spaced apart prongs extending from the back end of the slotted proximal anchor to a front end of the slotted proximal anchor, wherein the pairs of prongs join together at a slot inception, and wherein the prongs are are oriented to receive a tensioned portion of the suture;
wherein the prongs include inwardly facing protrusions that are configured to capture and deform the suture between the protrusions and prevent the suture from disengaging from the slotted proximal anchor once engaged; and
wherein inner surfaces of the prongs near the slot inception have a plurality of edges of engagement that deform and compress the suture between the prongs.
2. The anchor assembly of claim 1 , wherein the front end of the slotted proximal anchor faces the tensioned portion of the suture.
3. The anchor assembly of claim 1 , wherein terminating ends of the prongs are linearly tapered inwardly to facilitate receiving a section of the connector.
4. The anchor assembly of claim 1 , wherein the spaced apart prongs commence at a slot inception that steps outwardly to a wider dimension, thereby defining a space between the prongs.
5. The anchor assembly of claim 4 , wherein the space between the prongs of the slotted anchor has a dimensional interference, relative to the diameter of the connector.
6. The anchor assembly of claim 1 , wherein the inwardly protrusions comprise serrated teeth.
7. The anchor assembly of claim 1 , wherein the inwardly facing protrusions comprise barbs.
8. The anchor assembly of claim 1 , wherein the inner surfaces of the prongs are configured as corresponding inwardly facing U-shaped prongs, and wherein the inner surfaces of the prongs protrude into the connector.
9. The anchor assembly of claim 1 , wherein the prongs have a straight lead-in between terminating ends and a linear taper.
10. The anchor assembly of claim 1 , wherein the slotted proximal anchor is formed from a folded member.
11. The anchor assembly of claim 1 , wherein the slotted proximal anchor includes a seating portion spaced from the slot inception.
12. The anchor assembly of claim 1 , wherein the slot inception includes at least one barb.
13. The anchor assembly of claim 1 , wherein the prongs include terminal ends including inwardly directed protrusions.
14. The anchor assembly of claim 1 , wherein the prongs include interior planar surfaces leading to internal curved surfaces.
15. The anchor assembly of claim 1 , wherein the prongs include interior curved surfaces along their length.
