Publication number: 20240016516Abstract: Surgical devices having a plurality of outwardly-biased flexible fins capable of both inward convergence and outward flexion, provide for fluid retention and soft tissue retraction during surgical procedures. The outwardly-biased flexible fins also provide for soft tissue compression, decreasing the length of the interior central lumen or passageway through which instruments pass, allowing for a wider range of movement of instruments and better access to the surgical site, especially in patients with greater amounts of fat tissue that would otherwise require longer lumen lengths in prior art endoscopic cannulas. An exterior central lumen is formed above the interior central lumen, and has an opening at a top end, and a bottom wall separating the exterior central lumen from the interior central lumen. One or more slits are formed in the bottom wall of the exterior central lumen.Type: ApplicationFiled: July 20, 2023Publication date: January 18, 2024Inventor: Daniel A. Worrel

Publication number: 20230404567Abstract: A knotless surgical suture system having a means for shuttling a suture having a locking limb portion having a tapering thickness for mounting to an anchor point, thereby providing a knotless anchor provided by the interference fit of the suture itself. The system can be used in conjunction with various traditional “knotted” anchors, which can be loaded with the knotless suture shuttling and anchoring system, creating a knotless fixation solution. The knotless suture shuttling and anchoring system enables a surgeon to load the sutures to the anchor and lock them in place with the tapered locking limb portion. The combination of the knotless suture shuttling and anchoring system having a shuttling limb with a suture loop allows a surgeon to load sutures onto existing anchors, with the tapered locking limb portion used to create an interference fit, locking it into place.Type: ApplicationFiled: June 16, 2023Publication date: December 21, 2023Inventor: Daniel A.

An obturator assembly including a cannulated handle member with a cannulated shaft attached to said handle member, said shaft extending distally and terminating at a cannulated obturator tip. A hood structure found on such obturator tip may be used to secure one or more flexible fins prior to deployment.Type: ApplicationFiled: April 4, 2023Publication date: November 2, 2023Inventor: Daniel A.

Publication number: 20230115451Abstract: A graft compression system for compressing soft tissue grafts used in connection with reconstructive surgery. The graft compression system includes an upper press body and lower press body, pivotally couple to one another, each having inner sides having a plurality of parallel semi-circular shaped channels formed thereon. The plurality of parallel semi-circular shaped channels have sequentially decreasing channel widths. The upper press body and said lower press body of the graft compression system are configured to pivot about a pivot pin such that the inner sides abut one another, and such that the two sets of semi-circular shaped channels are substantially aligned with one another so as to receive a graft for compression. A screw press barrel is attached to the lower press body, on a side opposite the pivot pin, and is configured to compress the upper press body and lower press body.Type: ApplicationFiled: December 9, 2022Publication date: April 13, 2023Inventor: Daniel A.

Patent number: 11607322Abstract: A graft compression system for compressing soft tissue grafts used in connection with reconstructive surgery on the anterior cruciate ligament (ACL). The graft compression system includes a compression chamber having an elongate hollow shaft body having two ends that are threaded to mate with correspondingly threaded collet nuts. Collets are removably inserted into, and engage, the collet nuts fastened to opposing ends of the compression chamber A surgical graft may be inserted into a hollow compression tube having a lumen with a compressible diameter, said compression tube being sized for insertion into the collets and compression chamber. When such collet nuts are tightened by a user of the graft compression system, the inner diameters of the respective collet nuts nested within such collet nuts are decreased, causing the diameter of the lumen of the hollow compression tube to in turn be decreased and compress the surgical graft within.Type: GrantFiled: February 1, 2020Date of Patent: March 21, 2023Assignee: SUREMKA, LLCInventor: Daniel A.

Patent number: 11607246Abstract: Surgical device deployment apparatuses that include a cannula having a shaft with an exterior surface, and an interior surface forming a lumen within said cannula, the shaft having a distal portion with a plurality of apertures. An obturator configured to be used in conjunction with the aforementioned cannula has an obturator shaft with a distal portion having a reduced diameter, wherein said obturator shaft is insertable into said lumen of said cannula. In other embodiments, a surgical device deployment tool comprises a handle member with a shaft attached to a distal end of said handle member, said shaft extending distally and terminating at a shaft head. A hollow hood is attached to said shaft head, said hood having an inner surface formed such that a gap exists between said inner surface and an adjacent outside surface of said shaft head.Type: GrantFiled: July 8, 2019Date of Patent: March 21, 2023Assignee: SUREMKA, LLCInventor: Daniel A.
