Publication number: 20170354861Abstract: The present invention provides a sports protection device (e.g. a shin pad) for protecting a portion of a wearer's body (e.g. their shin). The sports protection device comprises a lining layer for facing the wearer's body (shin) and an opposing composite layer superimposed on said lining layer. The composite layer comprises wood particles within a thermoplastic polymer matrix. The lining and composite layers are shaped to substantially match the contour of the portion of the wearer's body (shin). A moldable blank for forming a sports protection device is also provided.Type: ApplicationFiled: March 6, 2017Publication date: December 14, 2017Applicant: ONBONE SPORTS LIMITEDInventors: Antti PÄRSSINEN, Ian CAMPBELL, Eija PIRHONEN

Publication number: 20060178702Abstract: A suture anchor, an insertion tool for inserting a suture anchor, and a device for internal working of hole in bony tissue. The anchor comprises an anchor body having a longitudinal cross-section defined by a perimeter. The perimeter comprises at least one tissue-intruding edge formed between the first side and the second side of the perimeter. The intruding edge is arranged to penetrate the tissue during a rotating motion of the anchor in said opening. The anchor further comprises an abutment surface, arranged substantially on the opposite side of the anchor body in relation to said intruding edge. The first side of the intruding edge is arranged to connect with the abutment surface by a connecting part of the perimeter having the shape of a substantially curved piece in said longitudinal cross-section.Type: ApplicationFiled: February 10, 2005Publication date: August 10, 2006Applicant: Inion Ltd.Inventors: Javin Pierce, Olli Karhi, Vesa Vuorisalo, Eija Pirhonen, Harri Happonen

Publication number: 20060115515Abstract: A biodegradable implant and a method for manufacturing one. The implant comprises a matrix component containing at least one biodegradable polymer or copolymer and a pyrrolidone plasticizer that is adapted to reduce the rigidity of the implant. The plasticizer substantially exits from the implant after coming into contact with tissue fluids of the organ system in such a manner that the bending resistance of the implant prior to the insertion of the implant into the organ system is lower than after its insertion into the organ system.Type: ApplicationFiled: November 30, 2005Publication date: June 1, 2006Applicant: INION LTD.Inventors: Eija Pirhonen, Timo Pohjonen
