Patent number: 8784479Abstract: A device for repairing a heart valve comprises an implantation instrument. The implantation instrument comprises a first support ring, and a second support ring connected to said first support ring to form a coiled configuration. The first support ring is configured to abut one side of the valve and the second support ring is configured to abut an opposite side of the valve to thereby trap a portion of the valve tissue therebetween. The device further comprises an annuloplasty implant adapted to be attached to the heart valve annulus in order to reshape the annulus and allow the leaflets to open and close properly. The annuloplasty implant is connected to the implantation instrument for insertion to the annulus.Type: GrantFiled: May 16, 2011Date of Patent: July 22, 2014Assignee: Medtentia International Ltd.

Patent number: 7226595Abstract: A conjugate between a target-seeking moiety and a modified superantigen, characterized in that the superantigen is a wild-type superantigen (SA I) in which an amino acid residue in a superantigen region (region I) determining binding to TCR, preferably TCRV?, and T cell activation have been replaced by another amino acid residue while retaining the ability to activate a subset of T cells. In preferred embodiment the modified superantigen is a chimer between at least two wild-type superantigens (SA I, SA II etc) characterized in that one or more amino acid residues in a region determining binding to TCR and T cell activation have been interchanged between various wild-type superantigens. A therapeutic method making use of modified/chimeric superantigens as defined in the preceding paragraphs. An antibody preparation in which the cysteine residues that provide for interchain disulfide bonds have been mutated so as to forbid interchain disulfide bridges, preferably to serine residues, for use as pharmaceutical.Type: GrantFiled: October 30, 2002Date of Patent: June 5, 2007Assignee: Active Biotech A.B.Inventors: Per Antonsson, Per Bjork, Mikael Dohlsten, Terje Kalland, Lars Abrahmsen, Johan Hansson, Göran Forsberg
