    摘要: A fixation implant generally includes at least one shaft configured to securely fit into a hole formed in bone. The shaft is of sufficient length relative to the interior diameter of the hole and, in some preferred embodiments, has locking protuberances, like threads, ridges, or barbs, that resist removal of the shaft from the hole in the bone when different types of forces, such as tensile or bending forces, are applied to the implant. The shaft is generally cylindrical in shape, however, in various embodiments, different cross-sections could be used. In a preferred embodiment the implant has a flattened and bent end portion emerging from only one side of the shaft. At the other side of the implant the outer surface of the shaft and the emerging end portion form a smooth surface, without any projections. This smooth surface at the end of the implant prevents irritation of the surrounding tissue. The end portion has a mating surface configured to grip a portion of the soft tissue surrounding the hole between the bone and the mating surface. The longitudinal axis of the shaft is oriented at an angle of less than 90 degrees relative to the mating surface. In this fashion, the implant anchors soft tissue, such as rotator cuff tissue, to bone.

    摘要: Porous bioabsorbable, bioactive and load-bearing composite medical device structure includes a plurality of regular textile planar layers (1a, 1b . . . ) formed of continuous bioabsorbable polymer matrix and bioceramic fibers acting as reinforcements, both included in continuous fibrous elements (3) forming the textile layers. The layers are placed on top of each other to form a structure having two dimensions (x, y) at right angles to each other according to the two dimensions of the textile layer and a third dimension (z) perpendicular to them and resulting from the piling of the layers. A plurality of passages extend through the layers as a result of the openings (2) defined by portions of the continuous fibrous elements (3) extending substantially in the direction of the plane. The continuous fibrous elements (3) comprise both bioactive ceramic reinforcing fibers which form a reinforcing structure and a bioabsorbable polymer matrix material which forms a matrix which binds the layers together and also binds the portions of continuous fibers defining the openings together, thereby forming the passages and stiffening the structure. This bioactive and bioabsorbable composite structure is suitable to be used as a basic structure in medical devices, especially in osteochondral applications where the load-bearing properties of implant are required.

    摘要: 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.

    摘要: This invention relates to a material that degrades after implantation into a patient's tissue, and resorbs into the patient's body, which material is manufactured of polymer, copolymer or polymer alloy. The material has a non-crystalline, i.e., amorphous structure and is molecularly oriented and reinforced by mechanical deformation. Further, the material can be formed into surgical devices, such as screws and pins, for implantation into a patient.

    摘要: The device of the present invention is designed for repairing a tear in soft and/or tough tissue of a patient, such as a tear in the meniscus of the knee. The device has a conduit, such as a cannula, that may be easily inserted into the patient and through which the fastener is delivered to the patient. This conduit is aligned with a seat for holding a fastener and the fastener is pushed, e.g., by a piston, from its seat and through the conduit and into the patient. In a preferred embodiment of the invention, the shape of the conduit exactly matches the shape of the cross-section of the fastener so that the surgeon may more accurately direct the angle and location at which the fastener enters the patient.
