Abstract: A drug-eluting self-retaining suture comprises a filament, a plurality of retainers, and a drug impregnated in or coated on the filament. The shape and distribution of retainers modifies the in vivo release kinetics of the drug. The drug release kinetics may be modified uniformly or region by region. The self-retaining suture may for example be used for reattaching severed nerves and release nerve growth factor or other regeneration accelerating agents into the region of the nerve injury.

Abstract: The invention relates to a hemostatic composition comprising a mixture of cellulose-based short and long fibers, preparation and use thereof.

Abstract: A method of attaching a surgical suture to a needle and testing the attachment includes dispensing a length of suture from a spool by using a first suture gripper, and using a surgical needle gripper for holding a surgical needle stationary. A leading end of the suture is inserted into and attached to a receiving end of the surgical needle. A second suture gripper is located between the first suture gripper and the spool. After the second suture gripper is closed for gripping the suture, the second suture gripper is advanced downstream toward the surgical needle to reduce the tension on the suture. The tension on the suture is reduced by moving the second suture gripper a pre-determined distance. The first suture gripper is opened for releasing the suture and the first suture gripper is moved toward the suture spool for re-grasping the suture at a location between the second gripper and the suture spool.

Abstract: Disclosed are compositions comprised of Oxidized Cellulose (OC), such as oxidized regenerated cellulose (ORC), and an antibiotic comprised of minocycline, methods of preparation thereof and uses thereof.

Abstract: Novel recessed surgical fastening devices are disclosed. The fastening devices have a compressible member and a fastening element disposed at least partially within the compressible member. The fastening element has at least one tissue engagement member that is extensible through the compressible member to engage tissue when a force is applied to the fastening device.

Abstract: The present invention relates to surgical instruments and methods for enhancing properties of tissue repaired or joined by surgical staples and, more particularly to surgical instruments and methods designed to enhance the properties of repaired or adjoined tissue at a target surgical site, especially when sealing an anastomosis between adjacent intestinal sections so as to improve tissue viability, prevent tissue infection, and to prevent leakage. The present invention further relates to an expandable compression device for application to anastomotically joined tubular tissues, comprising: an upper ring-shaped or disk-shaped flange at a distal end of said device connected to a lower ring-shaped inflatable flange at a proximal end of said device via a hollow cylindrical tubular body, with an opening forming an axial passage through said upper flange, lower flange, and tubular body.

Abstract: The present invention relates to surgical instruments and methods for enhancing properties of tissue repaired or joined by surgical staples and, more particularly to surgical instruments and methods designed to enhance the properties of repaired or adjoined tissue at a target surgical site. The present invention further relates to hypothermic linear stapling instruments configured to pre-cool the tissues being joined by staples.

Abstract: Novel mesh implant positioning systems for use in laparoscopic body wall defect repairs, such as hernia defects, are disclosed. The systems utilize one or more bar members combined with surgical sutures and needles to position a mesh implant adjacent to a body wall defect without the need for stay sutures. Also disclosed are assemblies of the positioning systems with surgical mesh repair implants, and methods of repairing body wall defects such as hernias with the assemblies.

Abstract: A device for application onto incisions or wounds with a liquid rapidly polymerizable adhesive for forming skin closure systems, having a flat porous mesh elongated along a longitudinal axis and having an upper side and an opposing lower or wound facing side and a central portion in immediate vicinity of the axis; further having a plurality of pores and windows in said mesh, said windows substantially larger than said pores and arranged along said longitudinal axis in said central portion; a crosslinking or polymerization accelerator or initiator disposed in or on the mesh; and a pressure sensitive adhesive disposed on at least a portion of the lower surface of the mesh.

Abstract: The present invention relates to improved hemostatic compositions comprising cellulose-based fibers supplemented with compounds, preparation and use thereof.

Abstract: A swaging system for attaching surgical needles to sutures and testing the attachment strength includes a frame, a bottom swaging die mounted on the frame, and a top swaging die mounted on the frame and being moveable up and down along a swaging axis that is aligned with the bottom swaging die. The bottom swaging die includes a hinge mechanism with a bottom plate mounted to the frame and a top plate overlying the bottom plate. The top and bottom plates are pivotally connected for enabling the top plate to pivot relative to the bottom plate. The bottom swaging die includes a swaging tool that extends toward the top swaging die along the swaging axis, and a load cell disposed between the top and bottom plates for monitoring load. The system includes a control system having one or more pull test programs stored therein for conducting pull tests on armed surgical needles to determine if the armed surgical needles are acceptable or unacceptable.

Abstract: A dispensing device and cartridge for simultaneous delivery and mixing of multiple co-reactive materials, the cartridge having proximal and distal ends, and having an elongated holder body with substantially parallel longitudinal voids. Multiple syringe bodies are disposed parallel within the voids and multiple co-reactive materials are separately disposed in the syringe bodies. The dispensing device also includes a longitudinal housing which is structured and arranged to receive the cartridge.

Abstract: Provided is a method of enhancing toxicity of a glycolytic dependent compound towards a cell, tissue and/or organ e.g. a diseased cell, tissue and/or organ, the method comprises contacting Oxidized Regenerated Cellulose (ORC) and/or Oxidized Cellulose (OC); and a glycolytic dependent compound with the cell, tissue and/or organ.
