A drive shaft and articulated jaws spread staple legs for bone insertion, then pry under the bridge for precise repositioning or removal.

A cutaway anchor cavity shields sutures and grafts during bone tunnel insertion while anti-backout features maintain secure fixation.

Integrated imaging on the elongate member and suture arm improves tissue targeting, needle placement, and secure retention in single-use suturing.

Magnetic suture capture replaces precise jaw positioning, improving retrieval accuracy under indirect non-stereoscopic visualization.

Multiple blade members form separated cog peaks in one pass, speeding biodegradable thread production and improving skin tissue coupling.

An angled multi-region cogged suture improves support for the nose bridge, columella, and tip while reducing protrusion and inflammation.

Multi-row soft suture staples and knotless anchors improve tissue-to-bone compression while avoiding knot bulk, pullout risk, and longer surgery.

A catheter hood and anti-migration anchor secure GI prostheses against peristalsis while avoiding tissue necrosis and bacterial translocation.

A tension-suture eyelet locks multiple repair sutures inside a soft anchor, reducing knots, migration risk, and deployment steps.

A tensioned flexible cable deploys and retracts a suture hook through tight needle bends, improving tissue targeting without buckling.

Tibial anchors and a suture sling stabilize the ankle syndesmosis without drilling the fibula, reducing stress fractures and tissue irritation.

A shape-memory anchor and clip secure mitral implants on moving heart tissue, improving leaflet coaptation with less-invasive delivery.

A polymer-covered bone fixation implant blocks metal-to-metal corrosion and adds tissue-engaging channels to improve stabilization during healing.

A coaptation element anchored to native leaflets seals regurgitant valve gaps with less leaflet stress and less invasive delivery.

A laterally extending reinforcement member spreads tether forces beyond the pad edge to prevent warping and maintain heart wall tension.

Cutting edges with a positive rake angle let the screw cut its own path, reducing insertion torque, equipment needs, and placement time.

A two-stage trigger trimming tool cuts implanted lines for controlled heart wall remodeling, helping reduce dilation, wall stress, and mitral regurgitation.

A locking strap replaces knots and clamps in ventral hernia repair, spreading force over more tissue to reduce tearing and simplify closure.

Alternating jaw rotation with stationary and rotary cams reproduces familiar suturing motion, reducing retraining in endoscopic stitching.

A two-part bone screw separates anchoring from attachment, improving surgical site visibility, placement control, and secure fixation.

Rotational actuation converts to precise needle travel, reducing instrument passes in bone anchor insertion and fitting different anchor lengths.

A tapered needle-to-wire suture assembly uses a larger wire diameter to seal sternal tissue openings and reduce bleeding during closure.

An RF perforation tip and adjacent laceration electrode with an anchoring barb combine puncture and leaflet cutting in one catheter.

A pre-knotted ligature and coupler mechanism lets surgeons encircle, tighten, and cut suture without repeated release and re-grasp.

Lengthwise suture, tape, or mesh reinforcement helps tendon grafts hold fixation and maintain tension while reducing stitch pull-through.

Detachable fixation features secure tissue grafts and bone blocks without whipstitching or extra suture tape, while limiting loop slip and creep.

Flexible anchor tubes and multi-pass sutures join tissue or bone with fewer large through holes, improving stability without weakening the construct.
