摘要:
A composition for reducing pain at a surgical wound site or trauma site comprising oxidized regenerated cellulose and a non-steroidal anti-inflammatory drug or pharmaceutically acceptable salt or ester thereof, where the non-steroidal anti-inflammatory drug is an acid having a secondary amine group; and a method of reducing localized pain at a surgical wound site or trauma site.
摘要:
Composite materials formed from biocompatible polymer fibers and biodegradable polymers are disclosed. The heat treatment conditions for the reinforcing fibers are described so that the mechanical properties of the fibers can be retained during composite consolidation process. The processing conditions and set-ups to consolidations are constrained to the temperatures lower than fiber heat treatment temperatures. The reinforcing fibers are restrained under tension so that the minimum relaxation occurs during consolidation process.
摘要:
An orthopedic screw with an internal bore and mating driver has a bioabsorbable polymer component. To increase the torque tolerance of the screw and to minimize the likelihood of the driver stripping inside the bore of the screw, the screw and driver are heat treated together to shrink fit the screw onto the driver thereby increasing the driver-to-screw contact and distributing the loading force over a greater area to protect against material failure. The heat treatment involves heating the screw to an elevated temperature and holding that temperature for a period to promote stress relaxation and/or crystallization of the material.

摘要:
A substantially flat implant for repositioning a patient's eyebrow that may allow for a gradient lift across the eyebrow. The implant may be geometrically non-symmetrical, and/or may have non-symmetric physical properties. The implant may include a foot portion that extends along a first longitudinal axis and has a length, and a vertical strip portion that extends outwardly from the foot portion along a second longitudinal axis. The strip portion has a length and a width that is smaller than the length of the foot. The second longitudinal axis is offset from the center of the length of the foot portion.

摘要:
Surgical sutures having a core extending along a length thereof between a first end and a second end, and a plurality of sets of first and second projections, wherein the first projections extend in a direction of a first end of the suture and the second projections extend in a direction of a second end of the suture. The first projections may be sized and shaped, and positioned relative to the second projections so as to be capable of substantially shielding the second projections when the surgical suture is drawn through tissue by the second end thereof. The first projections may additionally or alternatively be capable of overlapping and substantially covering a distal end of the respective second projections when the suture is drawn through tissue by the second end.
摘要:
A co-extruded tissue grasping monofilament and a method for making the same. The monofilament includes a core made of a first material and extending along a length of said monofilament, and a plurality of tissue grasping elements extending outwardly from the core at least along a predetermined portion of the length of the monofilament. The plurality of tissue grasping elements are made of a second, different material having a greater stiffness than the first material. The method for making the monofilament is by co-extrusion.
摘要:
An orthopedic interference screw has a hard, self-threading front section and a bioabsorbable rear section. The two sections are conjoined and threaded such that the hard front section cuts threads into the bone and the softer rear section follows the threads into the bone. Preferably, the screw has an axial bore for matingly receiving a turning tool such as a hex wrench.
