System, including apparatus and methods, for positioning medical material in living tissue using hollow elements that are formed unitarily from a synthetic bioabsorbable material. The hollow elements are optionally filled with a core material and a heat shrink process is performed so that the hollow elements are tightened around the core material.

A surgical needle assembly including a hollow needle body, a push rod slidingly fit within the hollow needle body, and a hand-actuable lock mounted on the needle body. The lock selectively limits movement of the push rod relative to the needle body in response to a squeezing or releasing of the lock.

A suture-material-dispenser system for a supply of dry suture material includes the supply of such material, a housing which defines a cavity for containing the supply, and desiccant preferably housed within the housing. The housing includes a top region that has an opening formed in it, and a bottom region with a semi-circular bearing positioned in it. A reel fits within the cavity on the bearing, and has wound on it the supply. An anti-contaminant, flip-top cover is pivotably attached to the top region, and is constructed for releasable closure over the top region substantially to prevent contaminants from entering the cavity. A gas-permeable, resilient member is also included and has a body that fits sealingly within the opening, which body has formed in it a suture-material-dispensing port to allow dispensing of suture material therethrough. The body is preferably formed from a substance with a hardness in the range of about 40-80 on a Shore A durometer. An on-board cutter is also attached to the housing adjacent the resilient member for allowing the user to cut a desired dispensed amount of material from such supply. The cover may also include a downwardly extending, elongate pressure applicator with a bottom surface that presses against the resilient member adjacent the port when the cover is closed over the top region. Preferably, the resilient member is formed from a material that is ethylene-oxide-gas permeable, such as liquid-injection-molded silicone.

Suture-material-dispenser system for suture material

An apparatus for dispensing string material such as suture from a rotating spool housed in a sealed housing which is filled with a liquid, for example an antiseptic fluid. The housing forms a hollow member into which the spool of suture is disposed so as to be freely rotatable. An end of the suture extends from the interior of the housing through a wiper member so as to be grasped by a user. The suture spool comprises an increased diameter core member which allows the entire length of suture stored thereon to be usable in an uncoiled manner when removed from the device. The center portion or core of the suture spool has a closed periphery so as to reduce the amount of antiseptic required to fill the interior of the housing and maintain the suture sterile. Also, the sidewalls of the housing are provided with projections that engage the sidewalls of the spool to permit a user to grasp and apply force against the housing while withdrawing the suture without slowing or stopping rotation of the spool.
