摘要:
A compound barb medical device comprising: an elongated body; at least one barb extending from the elongated body and defining an inner surface, the inner surface including: a first portion disposed at a first orientation relative to a longitudinal axis of the elongated body, a second portion disposed at a second orientation relative to the longitudinal axis, and a third portion disposed at a third orientation relative to the longitudinal axis.
摘要:
A compound barb medical device comprising an elongated body and a combination of compound barbs and single angle barbs formed along the length of the suture in specified or random patterns.
摘要:
A compound barb medical device includes a body portion and at least one barb extending therefrom. The at least one barb defines an inner surface. The inner surface includes a first portion disposed at a first orientation relative to a longitudinal axis of the body portion and a second portion disposed at a second orientation relative to the longitudinal axis. The at least one barb is made from a shape memory material which can be deformed into a temporary shape from a permanent shape. The barb projects from the body portion in a first position relative to the body portion when in the permanent shape and in a second position when in the temporary shape.

A system for forming a looped suture having a tapered cut is provided. The system includes a base for selectively retaining a portion of thread, a clamping device for receiving a first end of the thread, a tensioning device for receiving a second end of the thread, a welding assembly configured to join a first and second section of the thread to form a loop, and a cutting assembly configured to form a tapered end on the first section of the thread.
摘要:
A medical device having an elongate body having a proximal portion and a distal portion, the proximal portion of the elongate body terminating in a free end; the distal portion of the elongate body terminating in a loop. The loop further includes a first plurality of anchors disposed along a surface of the loop.
摘要:
A surgical stapling device (10) is disclosed for performing circular anastomoses. The surgical stapling device includes a handle portion (12), an elongated body portion (14) and a head portion (16) including an anvil assembly (30) and a shell assembly (31). The surgical stapling device includes a knife blade (188) possessing a lubricious coating which enhances the ability of the knife to cut through tissue and minimizes the knife sticking to tissue or other components of the surgical stapling device. The coating comprises at least one polydialkylsiloxane and at least one siliconization material.
摘要:
A method of forming a barbed medical device comprising the steps of: providing a blank workpiece; and forming at least one barb on the blank workpiece by: applying vibrational energy to a tool; and bringing the tool and the blank workpiece into contact at an angle such that the tool cuts into the surface of the blank workpiece.
摘要:
A system (100) and method for forming a looped suture (10) having a tapered cut (17) is provided. The system includes a base (110) for selectively retaining a portion of thread, a clamping device (120) for receiving a first end of the thread, a tensioning device (125) for receiving a second end of the thread, and a welding/cutting assembly (130) configured to join a first section and second section of the thread to form a loop and to form a tapered end on the first section of the thread. A die (200) for forming a looped suture having a tapered cut is also provided.
摘要:
A compound barb medical device comprising: an elongate body wherein the elongate body includes an outer surface, and the outer surface is in direct contact with tissue; at least one barb extending from the elongated body and defining an inner surface, the elongated body including: a first cut angle of from about 0 degrees to about 90 degrees, preferably from about 30 degrees to 40 degrees, preferably from about 31 degrees to about 38 degrees relative to the longitudinal axis of the elongate body; and a second cut angle of from about 0 degrees to about 90 degrees, preferably from about 1 degree to about 10 degrees, preferably from about 1 degree to about 8 degrees relative to the longitudinal axis of the elongate body; and wherein the medical device is formed of absorbable materials, non-absorbable materials and combinations thereof.
