摘要:
An inserter for simultaneously creating a bone tunnel and delivering an all-suture anchor. The inserter is capable of inserting into the bone tunnel a soft, non-rigid suture anchor by forming a bone tunnel (to serve as an anchor receiving area) and simultaneously, in one motion, delivering the soft suture anchor to the anchor receiving area. The soft suture anchor is made entirely of non-rigid materials including, but not limited to, filaments of soft, malleable materials such as those commonly used to make sutures. The inserter is able to not only carry or deliver the all-suture anchor into a bony substrate, but is able to do so without having to preform a hole in the bone.

An anchor is provided for placement in or against tissue. The anchor includes a fibrous construct and at least a first filament. Each filament passes through the construct in at least three passing locations including a first location nearest a first end of the construct, a last location nearest a second end of said construct, and at least one intermediate location between said first passing location and said last passing location. In an undeployed state, each filament extends a first length between said first location and said last location. In a deployed state, each filament extends a second length between the first location and the last location. The second length is shorter than said first length.

There is described a suture anchor with anchor members moveable as between a suture-unlocked configuration and suture-locked configuration. In one embodiment, the anchor members include an outer anchor member with features, e.g., flexible barbs, configured to secure the suture anchor in the suture-locked configuration to material proximate a pre-formed hole in bone material. The outer anchor member is also configured with a bore to receive suture material, and which is sized and shaped to receive an inner anchor member therein. The inner anchor member includes securing features such as projections that compress the suture material against the surface of the bore when the suture anchor is actuated from the suture-unlocked configuration to the suture-locked configuration.

This invention pertains to the percutaneous insertion of a soft, non-rigid suture anchor construct preloaded onto an inserter which is “self-punching”. The preferred embodiment of soft suture anchor disclosed herein is a suture anchor which is entirely comprised of filaments of compressible, distendable, soft materials such as commonly used suture materials. The inserter is adapted to not only carry the all-suture anchor into a bony substrate, but is also capable of forming a hole in the bone, to receive the anchor, in the same step.

A suspensory graft ligament fixation device is shown to be particularly suitable for maximizing the contact between a soft tissue graft and the bone tunnel prepared to receive the graft. The suspensory fixation device has an elongated anchor member adapted to be transversely situated at the exit of the bone tunnel. A loop member is suspended transversely from the anchor member and has a loop length which is adjustable. When a graft ligament is attached to the saddle end of the loop, the length of the loop member may be shortened to pull the graft member into the bone tunnel until it bottoms out at the floor of the bone tunnel.

A suture cutting device is provided, the device suitable for cutting high strength suture materials used in arthroscopic surgeries. The device includes a distal blade portion movable within a distal suture guide, the distal suture guide including a lateral suture guide slot. The distal blade portion includes a dorsal recess that, in combination with an upper wall of an enclosed blade guide slot, controls an amount of dorsal movement of a cutting edge during a longitudinal movement of the cutting edge. The combined dorsal movement and longitudinal movement of the cutting edge creating a sliding/slicing movement of the cutting edge against a suture in the suture guide slot. At least a proximal blade portion and an extension blade portion are made of a single blade, those portions defining a spring, contacting a trigger, and effectuating a movement from a first position to a second position.
摘要:
A dual pump irrigation/aspiration pump system capable of operating in a plurality of different modes suitable for a variety of different endoscopic surgical procedures. The system monitors actual or calculated intra-articular pressure and adjusts flow to maintain surgeon requested pressure at the surgical site while controlling outflow. The irrigation/aspiration pump system has an inflow pump and tubing dedicated to communicating fluid to the surgical work site and an outflow pump and tubing dedicated to removing fluid from the work site at a controlled rate. The system further has different size inflow and outflow pumps and tubing cassettes, means for altering the outflow fluid flow rate to accommodate a surgical tool and a means for declogging the surgical tool in the event of blockage. In a preferred embodiment a pressure control system provides inferred pressure information representative of the pressure at the work site.

A packaged residential fire pump system for sprinkler protection of one- and two-family dwellings. The system independently provides sufficient water pressure, and volume, for a two sprinkler flow for a period of time. An existing domestic water supply is supplemented with a dead water storage tank. The system can be combined with hydraulically sized, or scheduled, system piping and sprinkler heads.
