摘要： A suture passer including a longitudinally-extending hollow cannula having a central passage slidingly receivable of a surgical suture; a manually graspable handle connected to the hollow cannula for manipulation thereof, the handle having an upper surface; first guide means, connected to the upper surface of the handle, proximate a distal end of the handle, for releasably, guidingly holding the surgical suture; and second guide means, connected to the upper surface of the handle, proximate to the first guide means, for releasably, guidingly holding the surgical suture. The suture passer can be provided in a kit, for use in the suturing of internal tissue, along with a cannula bender, various hollow surgical needles and surgical suture material. The suture passer finds particular use in the suturing of internal tissues which are at least partially accessible through a body cavity, e.g. arthroscopic surgery.

摘要： A line lock includes a body at least partially bounding a primary passageway, a secondary passageway, and a working passageway. In one embodiment at least a portion of the working passageway is disposed between the primary passageway and the secondary passageway such that a geometric line segment extending between the primary passageway and the secondary passageway intersects with working passageway. A line extends through the primary passageway, the secondary passageway and then through the working passageway such that a relative compression section of the line is formed between the primary passageway and the secondary passageway. The compression section of the line selectively biases against a portion of the line extending out of the working passageway so as to selectively lock the line to the body when the line is tensioned against the body.

摘要： An apparatus and method for the reconstruction of a previously torn ligament using a tissue-engineered ligament. The tissue-engineered ligament includes a scaffold of biocompatible material having at least one layer and forming a sheet. The scaffold is placed in a cultured medium for seeding with fibrocyte forming cells. The seeded scaffold is then placed in an incubator to increase the number of cells. The seeded scaffold is then formed into a slender structure suitable for implantation. The method of making a tissue-engineered ligament includes forming a scaffold of biocompatible material having at least one layer forming a sheet. Next, the scaffold sheet is seeded with fibrocyte forming cells. The method further includes increasing the number of cells on the seeded scaffold and forming a slender structure suitable for implantation from the scaffold.

摘要： A fluid mixture dispenser has a container with independent fluid chambers that respectively maintain fluid components for combination. Each chamber includes an outlet and a driver. For each chamber, actuation of the driver effects the discharge of the fluid component through its outlet. The outlets of the fluid chambers open into a second container to receive a fluid mixture consisting of the fluid components, where the second container also includes an outlet and a driver. Actuation of the driver for the second container effects the discharge of the fluid mixture.

摘要： A method and apparatus for mixing bone cement which produces bone cement essentially free of entrained air. The apparatus includes a cartridge having two telescoping cylinders. The outer cylinder receives a cap thereon which hermetically seals the cartridge. The cap includes an outlet port in which a break-away agitator is installed and a port for connection of a vacuum pump. In use, a desired vacuum pressure is drawn on the cartridge and the inner cylinder is allowed to be drawn into the outer cylinder while the vacuum is being drawn, whereupon the inner cylinder automatically stops moving relative to the outer cylinder when the desired vacuum pressure is reached. Mixing of the bone cement is then performed under the partial vacuum thereby created. The agitator paddles provide a scraping action against both inner cylinder walls of the telescoping cylinders thereby improving mixing. After mixing, the agitator is broken away, an appropriate nozzle is attached to the cartridge and the cartridge is inserted into a cement gun. The leading portion of the bone cement develops a convex profile when axially advanced through the cartridge and the piston plug includes a tapered protrusion which generally corresponds to the profile of the bone cement. The cap and paddles are also shaped correspondingly to the convex profile developed by the bone cement, resulting in substantially all of the bone cement being squeezed from the cartridge. An air escape passage is also provided to vent air contained within an annular gap between the agitator shaft and the cap upon initial being essentially free from entrained air.
