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.
摘要:
An anchoring device having an elongate body at a proximal portion, a distal portion of the elongate body forming a loop at a distal portion of the anchoring device. The loop further includes a plurality of anchors disposed along a surface thereof and the loop also including an end effector. Methods for securing anchoring devices of the present disclosure are also disclosed.
摘要:
A medical device having an elongate body at a proximal portion, a distal portion of the elongate body forming a loop at a distal portion of the anchoring device. The loop may further include a plurality of barbs disposed along a surface thereof and the loop also including an end effector. The elongate body, loop, and/or medical device may be formed from shape memory polymers. Methods for securing medical devices of the present disclosure are also disclosed.
摘要:
A suture comprising: an elongate body including an outer surface; at least one barb extending from the elongated body and defining an inner surface, the inner surface including: a substantially linear first portion disposed at a first orientation relative to a first longitudinal axis of the elongate body, wherein the first portion is disposed at a first angle from about 31 degrees to about 38 degrees relative to the first longitudinal axis of the elongate body; and a substantially linear second portion disposed at a second orientation relative to a second longitudinal axis of the elongate body, wherein the second portion is disposed at a second angle from about 1 degree to about 8 degrees relative to the second longitudinal axis of the elongate body; wherein the barbs are equally spaced and project towards one end of the suture, wherein at least one end of the suture comprises a loop; and wherein the suture is formed of absorbable materials, non-absorbable materials and combinations thereof.
