Abstract: The invention concerns composite surgical devices and a method of manufacturing thereof. The device comprises a tissue fixation implant and a protruding member attached to the implant. The method comprises providing a polymeric implant preform comprising a fixation zone for the protruding member, inserting a protruding member into the fixation zone of the preform, inserting the preform into a mold cavity corresponding to desired shape of the tissue fixation implant and comprising at least one orifice for receiving the protruding member and subjecting the preform to heat and pressure for giving the tissue fixation implant the desired shape and attaching the protruding member to the tissue fixation implant.

Abstract: Surgical osteosynthesis composite material which has three components: biodegradable polymer reinforcement, bioceramic or bioglass filler reinforcement and biodegradable polymer matrix. This invention relates to biodegradable materials used for bone fracture fixation devices and methods of their manufacture. Unlike other known materials used prior to this application, the composites of this invention have two different reinforcing phases and one matrix phase. One reinforcing element is referred as the polymeric reinforcing element and the other as the ceramic reinforcing element.

Abstract: A biodegradable implant for installation in living tissue having a first section made from a first bioabsorbable material and a second section made from a second bioabsorbable material, wherein the first and second sections are connected, the first section having a first rate of degradation in living tissue and a first rate of expansion in living tissue and the second section having a second rate of degradation in living tissue and a second rate of expansion in living tissue.
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.
