摘要:
Self-retaining suture systems including a suture thread bearing a plurality of laser-cut retainers are disclosed. A laser system allows the creation of retainers and self-retaining suture systems in configurations which are difficult and/or impossible to achieve using mechanical cutting technology.
摘要:
A marked heterofunctional suture thread has two or more sections having different features. One or more sections of the suture thread are provided with laser-marked and non-laser marked indicia in order that they may be identified and differentiated from other sections. The suture thread may have retainers on the surface of one or more sections such that the suture thread can engage and retain tissue without knots. The markers may be used to indicate fixed features of a section of suture thread such as the presence and/orientation of retainers. In particular embodiments, laser-marked and non-laser marked indicia are used to identify the transition section of a bidirectional self-retaining suture.

摘要:
A self-retaining braided suture comprises a braided suture with tissue retainers formed on the surface such that the suture can engage and retain tissue without knots. The suture includes a plurality of braided fibers which may be covered by a non-braided sheath of a material which enhances the formation, elevation and/or deployment of the retainers. The retainers can be formed so as not to disrupt the braided fibers. The self-retaining braided suture has properties which enhance the tensile strength of the suture while preserving flexibility and durability. Methods for manufacturing and using self-retaining braided suture are also described.
摘要:
The present invention relates to self-retaining (“barbed”) systems for surgical procedures, methods of manufacturing self-retaining systems for surgical procedures, included their uses and testing. In various embodiments of the invention, a device and method for barbing sutures uses a laser to cut the suture under appropriate temperature and tensile strength conditions. In various embodiments of the invention, a device and method tests the tensile strength and elasticity of a barbed monofilament or multifilament suture. In various embodiments of the invention, a potting material can be used to retain one end of the suture for manufacture or testing.
摘要:
A structurally-embedded electronics assembly is disclosed and includes an outer skin member which is lightly loaded structurally, a primary load-carrying member positioned inboard from the outer skin member, a core member positioned between the primary load-carrying member and the outer skin member, an intermediate skin member positioned between the outer skin member and the core member and an electronics structure positioned between a predetermined two of the members or intermingled with a predetermined number of the members set forth above which are adjacent each other. In another embodiment, a thermally conductive baseplate member is positioned inboard from the primary load-carrying member. In another embodiment, a vibration damping member is positioned inboard from the primary load-carrying member.
摘要:
A system for monitoring strains and stresses on rope structures and rigid structures containing the ropes is provided wherein a fiber optic is included in a rope structure and change in the fiber's light transmissive/reflective properties, which are caused by strains and stresses on the fiber, are monitored.
摘要:
The present disclosure provides annular support structures for use in conjunction with stapling devices. These annular support structures may be suitable for reducing occurrences of leaking, bleeding and/or stricture, as well as anastomotic tension, when anastomosing various body structures.
摘要:
A method and device to elevate retainers on a suture thread to a desired angle such that the retainers can retain the desired elevation. The retainers can be elevated using an apparatus having at least one roller and at least one bending bar, wherein the bending bar contacts the retainers adjacent to the at least one roller to apply a force to the retainers. The retainers can also be elevated using a tube-shaped apparatus. A suture can be made up of an inner core and a coating that upon a stimuli increases the protrusion of the retainers away from the suture core. A coating can be inserted into the cut associated with the retainer and repulsive or expansive forces result in a pushing out of the cut and distending of the retainers away from the suture core.
摘要:
A laser-machining system and method is disclosed for forming retainers on a suture thread. The laser system is preferably a femtosecond laser system which is capable of creating submicron features on the suture thread while preserving strength of the suture thread. The laser-machining system enables creation of retainers and self-retaining suture systems in configurations which are difficult and/or impossible to achieve using mechanical cutting technology.
