Patent number: 7964206Abstract: 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.Type: GrantFiled: August 20, 2004Date of Patent: June 21, 2011Assignee: Bioretec OyInventors: Esa Suokas, Pertti Törmälä, Nureddin Ashammakhi, Heimo Ylänen, Mikko Hupa

Patent number: 7419681Abstract: A method of enhancing the drug release rate from a composite material. The composite material includes a synthetic, bioabsorbable polymer matrix and a drug particle phase dispersed therein. The release rate of the drug from the polymer matrix is enhanced by orienting the composite material. The drug release rate of the oriented composite material is greater than the drug release rate from an otherwise comparable non-oriented composite material.Type: GrantFiled: December 2, 2004Date of Patent: September 2, 2008Assignee: Bioretec, Ltd.Inventors: Pertti Törmälä, Esa Suokas, Minna Veiranto, Nureddin Ashammakhi

Publication number: 20070134292Abstract: The invention relates to synthetic, bioabsorbable polymer materials and implants, like fibres, sutures, meshes and other tissue management, wound closure or tissue engineering devices, which contain: a) a bioabsorbable polymeric matrix; b) antibiotic and/or anti-inflammatory agent particles or mixture thereof, dispersed in the matrix, and c) optionally an additive agent to facilitate device recognition and/or handling to facilitate the use and application of finalized product. In the matrix, cavities around the particles are induced by mechanical processing of the matrix phase. A preferred embodiment of the present invention is a device (suture) that provides a sustained release of antibiotic agent over several days to several weeks for the prevention or treatment of infection. The sutures may be effectively implanted into or in the vicinity of: 1) infected tissue, 2) potentially infected tissue, or in tissues where infection, should it occur, leads to disastrous consequences.Type: ApplicationFiled: July 19, 2004Publication date: June 14, 2007Inventors: Esa Suokas, Nureddin Ashammakhi, Pertti Tormala
