Commissure and annulus alignment helps a transcatheter heart valve mimic native flow, reducing interference, leak risk, and pacemaker implantation.

A deformable soft anchor and transfer-loop design removes knot-tying while improving fixation consistency, suture handling, and bone preservation.

A curved lower jaw and downward-curving needle guide sutures through soft tissue while reducing trauma and easing needle handling.

Bone-tunnel anchors and a suture sling stabilize the basal joint with less invasive surgery, avoiding tendon sacrifice, pinning, and long recovery.

Hydration-driven swelling changes suture surface texture and barbs to improve bone retention, reduce laxity, and support stable repair.

A one-way locking ferrule tensions and locks sutures without knots, preventing backsliding and improving tissue repair stability under trauma.

A porous woven suture tape implant balances soft tissue reinforcement with tissue ingrowth, using bone anchors for secure tensioning.

Angled suture tunnels redirect tearing and closure forces through retaining bars to reduce scarring while maintaining wound closure.

A shuttle loop threaded through a lumen repair strand closes tissue tears without knot-tying, cutting surgical time and failure points.

Vacuum tissue capture and needle retrieval enable remote suture passage with less undermining, smaller incisions, and lower tissue damage.

A flexible transurethral anchor delivery approach stabilizes device position for precise BPH implant placement with less discomfort and shorter catheter use.

A tapered repair suture wedges in the anchor channel to give tactile tensioning feedback and reduce slippage or pullout under cyclic loading.

A rotating catheter deploys suture loops and a knotless anchor to close large vessel punctures with fewer instruments and lower contamination risk.

A flexible self-locking implant adapts to muscle wall motion to repair hernia holes with less trauma, no fixation tools, and lower recurrence risk.

A pre-attached suture loop and reinforcement material strengthen soft tissue graft fixation and reduce tendon pull-through in ACL repair.

An adjustable loop and self-locking button secure ACL grafts in bone tunnels without premeasuring length, reducing loosening and micromotion.

A detachable front delivery assembly enables controlled sequential prosthesis implantation, cutting tissue repair steps and surgeon skill demands.

Independently tensioned, lockable soft anchors create dense tendon-to-bone fixation that reduces micromotion and supports faster rotator cuff recovery.

Negative pressure, dual expandable seals, and a roughened sleeve anchor devices in tissue cavities while maintaining a seal against enteric flow.

A cinched continuous loop replaces surgical knotting to secure native tissue bundles with better stability, load bearing, and less gap formation.

Independent locking loops replace knot-tying to maintain tension, simplify fixation, and improve repair stability in joint reconstruction.

Elastic pushing elements lock a flexible hernia patch into the muscle hole without sutures, improving stability while moving with tissue.

Grasping arms and guided needles enable less-invasive heart valve suturing with more predictable placement and reduced procedure time.

A plastic scissor assembly with metal blades and a forked tip cuts bandages and removes staples or sutures without autoclaving.

Preplaced septal sutures and a cutting catheter create controlled large-bore atrial access with rapid closure and later re-access.

A latch-actuator mechanism holds the ferrule in place until needle actuation, preventing loose ferrules and incomplete stitches.

Overlapping anchor-linked sutures stabilize the thumb joint after trapeziectomy, reducing incision burden, recovery time, and fixation complications.

A combined jaw layout applies linear staples and a purse string suture in one pass, creating a larger tissue cuff for more reliable anastomosis.

Movable single-anchor cartridges feed a deployment position one at a time, improving non-line-of-sight placement and preventing simultaneous anchor release.

Catheter-delivered clamps and anchors place adjustable artificial chordae to repair mitral regurgitation without open-heart surgery.

Separate inner and outer grooves organize stiff wire and flexible suture sections to prevent tangling and enable smooth sterile heart implant deployment.

A proximal nail extends medially into the humeral head to improve fracture reduction and reduce collapse during healing.

Pre-twisting and low-temperature coiling preserve lifting thread elasticity, extend hydrolysis time, and reduce sagging and skin marks.
