Surgical fastener for tissue treatment
First Claim
1. A surgical fastener for repairing tissue comprising:
- a shaft having a longitudinal axis and including proximal and distal portions, said proximal portion having a blunt tip and comprising at least one protrusion configured to resist movement in the distal direction, said distal portion having a pointed tip and comprising at least one protrusion configured to resist movement in the proximal direction and configured to permit movement of the shaft in the distal direction said shaft comprising a plurality of longitudinal ridges, each longitudinal ridge defining a channel that extends from the proximal portion to the distal portion, wherein said fastener is capable of being pushed from behind so that the fastener is located entirely within said tissue to be repaired.

Abstract
The present invention relates to a surgical fastener or device (implant) formed in the shape of an arrow comprising a shaft with a proximal (first) portion having protrusions and a blunt end and a distal (second) portion having protrusions and a pointed end, the protrusions of the proximal and distal portions configured to lock the implant in a position inside a soft and/or tough tissue according to the use of the implant. The implant may be manufactured of a polymer or a polymeric compound which is substantially (bio)absorbable in tissue conditions and contains oriented reinforcing structure or the like of a polymer or polymeric compound or ceramic bioglass compound. The surgical implant of the invention is particularly but not solely intended to be used in repair surgery of traumas of soft and/or tough tissues containing fibrous structures, such as knee meniscal tissues.

8. A surgical fastener for repairing a tear in a meniscus comprising:
-
a shaft having a longitudinal axis and proximal and distal portions, said proximal portion having a blunt tip and comprising at least one protrusion configured to resist movement in the distal direction, said distal portion having a pointed tip and comprising at least one protrusions configured to resist movement in the proximal direction and configured to permit the movement of the shaft in the distal direction, said shaft comprising a plurality of longitudinal ridges, each longitudinal ridge defining a channel that extends from the proximal portion to the distal portion of the shaft, wherein said fastener is capable of being pushed from behind so that the fastener is located in its entirety within the meniscus. - View Dependent Claims (9)
aligning the fastener of claim 8 on the surface of the meniscus;
positioning the fastener into the meniscus by pushing the said fastener into the meniscus from behind so that the fastener bridges and closes the tear and the fastener is located in its entirety within the meniscus.
