1. A tissue connector comprising:
- an elongated body with a generally circular cross-section and being flexible and substantially nonresilient, the elongated body having a first end, a second end, a periphery, and a plurality of barbs extending from said periphery of the elongated body,wherein said barbs comprise a first side forming an obtuse angle with the elongated body and a second side forming an acute angle with the elongated body, said barbs having a constant proportion as they extend along a portion of said body, where the first side of said barbs face the first end of the elongated body, the barbs being configured such that the barbs are yieldable in a direction toward the elongated body when the tissue connector is moved through tissue in a direction of the first end, and are generally rigid when the tissue connector is moved in an opposite direction toward the second end; and
wherein a barb is located at each of a plurality of axial locations of said body, a first side of each barb facing said first end, and barbs are about equally and uniformly circumferentially spaced about the periphery of the body in a helical pattern and are oriented in the same direction, andsaid first end including a pointed end and being sufficiently hard to pierce tissue, and said second end including a head.

Abstract
A tissue connector has a first pointed end, an anchor end, a body with a periphery and a plurality of barbs projecting from said periphery of said body. The plurality of barbs are yieldable in one direction, which direction is the direction of motion of the first pointed end through tissue, and are rigid in an opposite direction, which is in the direction of the anchor end. At axial locations of said body, said barbs are about equally located about the periphery of said body. At axial locations on a cylindrical periphery of the body barbs are locate at about 120 degree spacings. The barbs are conically shaped.

15. A tissue connector comprising:
-
a flexible and substantially nonresilient elongated body with a generally circular cross-section having a first end, a second end, a periphery, and a plurality of barbs extending from said periphery of the elongated body, wherein said barbs comprise a first side forming an obtuse angle with the elongated body and a second side forming an acute angle with the elongated body, said barbs having a constant proportion as they extend along a portion of said body, and wherein the first side of the barbs face said first end of the elongated body, the barbs being configured such that the barbs are yieldable in a direction toward the elongated body when the tissue connector is moved through tissue in a direction of the first end, and are generally rigid when the tissue connector is moved through tissue in an opposite direction toward the second end; and wherein a barb is located at each of a plurality of axial locations of said body, a first side of each barb facing said first end, and barbs are about equally and uniformly circumferentially spaced in a helical pattern and are oriented in a same direction about the periphery of the body, and said first end including a pointed end and being sufficiently hard to pierce tissue, and said second end including a head; and said head is larger than a diameter of said elongated body and said head is adapted to prevent tissue from going past said head such that said head is adapted to be located adjacent to tissue. - View Dependent Claims (16)
