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 a blunt end and tapered form, such that the proximal portion is broad at its blunt end and tapers in the direction of a distal (second) portion of the shaft, the distal portion having protrusions and a pointed end, wherein the tapered form of the proximal portion and the protrusions of the distal portion are 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 (resorbable) after implantation in tissue and contains an oriented reinforcing structure or the like of a polymer or polymeric compound or ceramic bioactive glass compound.

L'invention porte sur un élément ou dispositif de fixation (implant) chirurgical ayant la forme d'une flèche et comprenant une tige dotée d'une (première) partie proximale à extrémité arrondie et de forme conique de sorte que cette partie proximale soit élargie au niveau de l'extrémité arrondie et s'amincisse dans le sens de la (seconde) partie distale de la tige, cette partie distale étant constituée d'éléments saillants et d'une extrémité pointue. La forme conique de la partie proximale et les éléments saillants de la partie distale sont configurés de façon à bloquer l'implant à l'intérieur d'un tissu mou et/ou souple selon l'utilisation que l'on souhaite en faire. L'implant peut être fabriqué dans un polymère ou un composé polymère pratiquement (bio)absorbable (pouvant se résorber) après implantation dans les tissus et possède une structure de renforcement orientée ou analogue d'un polymère ou composé polymère ou d'un composé de verre et de céramique bioactif.
