Abstract: An expandable implant having a helical body and first and second securing pieces. Ends of the helical body are connected to the first and second end pieces. The first and second end pieces can be rotated relative to one another to expand the implant from a first dimension to a selected second dimension. The implant further includes a locking arrangement to maintain the implant at the selected second dimension.

Abstract: A delivery system for deploying an occlusion device comprises a piston having a threaded proximal end, an elongated delivery catheter having a proximal end, a distal end, and an inner lumen extending between the proximal and distal ends of the delivery catheter, and a drive mechanism comprising an internally threaded nut member and a spring member. The piston, which is coupled at a distal end to the proximal end of the delivery catheter, is moveable between a first axial position and a second axial position. The internally threaded nut member is configured to receive the threaded proximal end of the piston. The spring member, which is coupled to the internally threaded nut member, is configured to rotate the nut member to drive the piston from the first axial position toward the nut member to the second axial position. Driving the piston toward the nut member retracts the attached delivery catheter and deploys an occlusion device from within the inner lumen and through the distal end of the delivery catheter.

Abstract: A delivery system for delivering an occluding device to a body lumen comprises an elongated shaft having a proximal end and a distal end, a delivery means for delivering the occluding device to a desired location within the body lumen, and a flexible atraumatic tip on the distal end of the elongated shaft. The distal end of the elongated shaft is insertable into the body lumen. The atraumatic tip is configured to guide the elongated shaft through the body lumen while avoiding perforation of the body lumen.

Abstract: A system for ligating a uterine artery in a patient generally includes a suture transfer tool, suture transfer darts, and one or more sutures. The suture transfer tool includes an upper jaw that is pivotally joined to a lower jaw. The lower jaw of the tool includes a number of suture capturing pins. The suture transfer darts are configured to be tissue piercing and are positionable within the suture capturing pins. Each end of the suture is connected to a suture transfer dart. When operating the tool, the suture transfer darts pierce through the tissue to either side of a patient's cardinal ligament, which contains the uterine artery, and simultaneously present an end of the suture to either side of the cardinal ligament. As such, the suture is in an open loop configuration about the cardinal ligament and can be tied tight to the ligament to occlude the uterine artery.

Abstract: Surgical procedures, tools, and kits particularly suited to effect uterine artery ligation in a minimally invasive manner to treat uterine fibroids or other conditions of the uterus are disclosed. An incision through the fornix is made to access the uterine arteries supported by the cardinal and uterosacral ligaments. A distal end of one or more sutures is passed around each uterine artery and a portion of the ligament supporting and enclosing the uterine artery, wherein the portion may include a uterine vein. The passage is effected by directing a suture distal end along a first side of the portion of the ligament beyond to the fornix incision, then through the ligament, and then back proximally along the second ligament side toward the fornix incision.

Abstract: A bone fixation device including a retainer and an anchor. The retainer includes first and second receiving regions. The first receiving region is configured for receipt of a connecting rod. The second receiving region is configured for receipt of an anchor. The first receiving region is constructed so that a connecting rod can be positioned within the receiving region at a number of non-coaxial orientations. The first receiving region is also constructed to accommodate a curved connecting rod. A flexible, integral locking structure is located between the first and second receiving regions. The locking structure is arranged to secure each of the retainer, an anchor, and a connecting rod in a position relative to one another.

Abstract: A bone screw arrangement including a retainer and an anchor. The retainer includes a first receiving region configured for receipt of a connecting rod, and a second receiving region configured for receipt of the anchor. The second receiving region includes an upper socket and a lower socket. The arrangement includes an interface that transfers torque applied to the retainer, to the anchor for securing the anchor to a bone element.

Abstract: Bone fixation systems for stabilizing bones such as vertebral bodies are disclosed. The fixation systems include fixation connectors that preferably are equipped with bone anchors (e.g., screws, hooks, pins or like structures) for securing the fixation connectors to bones desired to be stabilized. The fixation systems also include linking elements (e.g., rods, plates or other members) for linking the fixation connectors together to form a stabilizing construct capable of maintaining a desired spacial relationship between bones desired to be stabilized.

Abstract: A set of surgical instrument for use with expandable spinal implants. The set of instruments includes box chisels designed to prepare a site for implant placement. The set of instruments also includes inserter/expander instruments configured to place and expand an implant at the site. The set of instrument further includes assembling/collapsing instruments configured to assemble an implant, and collapse or reduce the height of an expanded implant.

Abstract: A surgical driver for use with an implant, having a shaft with proximal and distal ends and an attachment piece with proximal and distal ends. The surgical driver including a coupling arrangement that couples the shaft and the attachment piece relative to one another. The coupling arrangement includes a recess formed at the proximal end of the attachment piece and has at least one retaining member for reversibly engaging the shaft. The coupling arrangement is adapted to accommodate interaction between the surgical driver and an implant so that variable-axis torque on the implant is minimized.
