Patent number: 7541049Abstract: 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.Type: GrantFiled: September 2, 1997Date of Patent: June 2, 2009Assignee: Linvatec Biomaterials OyInventors: Pertti Törmälä, Minna Kellomäki, William Bonfield, Kathleen Elizabeth Tanner

Patent number: 6991646Abstract: Method and apparatus for delivering a stent, including, but not limited to, a self expanding stent, into a body lumen. The apparatus comprises an outer tube having a proximal end and a distal end and sized to hold a stent therein in a radially constricted condition, an inner tube within the outer tube and having a proximal end and a distal end, and a holding element comprising one or more inflatable balloons carried on the inner tube at the location of the loaded stent. The balloon can be inflated prior to the procedure so that the balloon presses against the inner surface of the outer tube trapping the stent in its longitudinal position between the inner and outer tubes. Accordingly, the outer tube can be slid proximally to release the stent or distally to retract the stent back into the delivery device without the stent inadvertently sliding.Type: GrantFiled: December 18, 2001Date of Patent: January 31, 2006Assignee: Linvatec Biomaterials, Inc.Inventors: Claude O. Clerc, Kimberly Ann Fischer

Patent number: 6951565Abstract: Devices for dispensing suture threads and/or suture threads with needles attached to them that are particularly useful for inserting surgical implants, such as suture anchors, that make use of sutures. The devices use a novel spool design to safely and neatly hold the suture thread and/or needles until the surgeon wishes to dispense them.Type: GrantFiled: April 24, 2002Date of Patent: October 4, 2005Assignee: Linvatec Biomaterials Ltd.Inventors: Michael Keane, Bill Reimels, Michael Waters

Patent number: 6902575Abstract: A method and apparatus for inserting a self expanding stent into a delivery device and delivering the stent into a body lumen. The apparatus comprises an outer tube; an inner tube; a capturing element slidably mounted on the inner tube and including a foldable sleeve, a blocking element fixed to the inner tube adapted to block a stent from being inserted into the sleeve proximally of the blocking element and to block the capturing element from becoming situated distally of a predetermined point relative to said inner tube, the capturing element carried on the inner tube so that the distal end of the sleeve can extend beyond the distal end of the outer tube in an unfolded condition and be drawn into the outer tube by the blocking element. A stent having an end inserted into the sleeve is drawn into the outer tube, thereby becoming captured within the outer tube.Type: GrantFiled: December 18, 2001Date of Patent: June 7, 2005Assignee: Linvatec Biomaterials, Inc.Inventors: Kari Aarne Juhani Laakso, Juha-Pekka Nuutinen, Claude O. Clerc

Patent number: 6692499Abstract: 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.Type: GrantFiled: July 2, 1997Date of Patent: February 17, 2004Assignee: Linvatec Biomaterials OyInventors: Pertti Törmälä, Timo Pohjonen, Markku Tamminmaki
