Patent number: 9980814Abstract: The kit (10) of the invention includes a valve bearing (16) that can be radially deformed. The bearing (16) includes an outer peripheral wall (22) defining a central passage (40) having an axis (X-X?). The bearing (16) further includes an inner peripheral wall (24) defining an inner lumen (44) having a radial dimension lower than that of the central passage (40). The kit (10) includes a prosthetic valve (18) to be placed on the inner peripheral wall (24). The inner peripheral wall (24) extends in the central passage axially relative to the outer wall (22). The valve bearing (16) includes a means (26) for maintaining the inner peripheral wall (24) radially remote from the outer peripheral wall (22). The inner peripheral wall (24) and the maintaining means (26) define an inner blood circulation region (56) containing the lumen (44) which is tightly isolated from an outer region (58).Type: GrantFiled: May 30, 2008Date of Patent: May 29, 2018Assignee: CORMOVEInventor: Mikolaj Styrc

Patent number: 9427317Abstract: This device includes a hollow support delimiting, in the vicinity of a distal end, a transverse retention opening. It further includes an endoprosthesis which can be deployed between a state retracted against the support and an expanded state. The device further includes a filamentary connection forming a clamping ring surrounding the endoprosthesis and forming a loop engaged in the support through the retention opening. A retention rod mounted to be movable in the support, and the retention rod has a hook for retaining the loop. The displacement of the retention rod from a release position to a retention position brings about the tightening of the clamping ring.Type: GrantFiled: April 3, 2007Date of Patent: August 30, 2016Assignee: CORMOVEInventor: Mikolaj Styrc

Patent number: 9314355Abstract: A device includes a tubular endoprosthesis (11) and a hollow prop (13) provided in the vicinity of a distal end with at least one transverse retaining opening (23A). The device includes a releasable retaining member (31).

The traction means (45) extend at least as far as a control end in the vicinity of a proximal and of the prop (13) and can be moved relative to the prop (13) towards the distal end of the prop (13) to a position in which the endoprosthesis (11) is in an expanded state. The invention is applicable to releasing endoprostheses in a blood vessel.Type: GrantFiled: December 3, 2004Date of Patent: April 19, 2016Assignee: CORMOVEInventors: Mikolaj Styrc, Ning Wen

Patent number: 8167934Abstract: This implant comprises an endoprosthesis having an axis which can be spontaneously deployed in a radial manner between a compressed configuration and a dilated configuration. The implant comprises at least one radial runner which comprises a separation surface which extends radially with respect to an outer surface of the endoprosthesis and a member which can be deployed away from the axis. The runner is arranged so as to delimit a confinement housing which extends between the separation surface and the outer surface and a radial spacer which is defined by the separation surface and the deployable member. When the implant is retained in a state of radial compression, the maximum radial width of the housing is less than the maximum radial width of the spacer which is not equal to zero.Type: GrantFiled: September 26, 2007Date of Patent: May 1, 2012Assignee: Laboratoires PerouseInventors: Mikolaj Styrc, Eric Perouse

Publication number: 20080147183Abstract: The endovalve comprises an endoprosthesis deployable between a contracted state and an expanded state. The endoprosthesis defines an internal duct. The endovalve includes a valve placed in the internal duct and movable between a closed configuration shutting the duct and a release configuration leaving the duct open. The endovalve has connection means between the valve and the endoprosthesis. The connection means comprise at least one intermediate connection member connected to the endoprosthesis and including at least one region that is movable relative to the endoprosthesis. The valve is fastened to the movable region.Type: ApplicationFiled: December 12, 2007Publication date: June 19, 2008Inventor: Mikolaj Styrc

Publication number: 20080103586Abstract: This implant (10) comprises a hollow body (30) adapted to be deployed between a compressed configuration and a totally dilated configuration constituting its rest configuration. The hollow body (30) has an internal surface (40) with an axis (X-X?) which delimits a blood circulation passage (42). The implant (10) comprises at least a constricting flexible threadlike link (68) which is linked to the hollow body at at least two linking points (60A, 60B, 60C) which are spaced angularly round the axis (X-X?) on its internal surface (40). The link (68) can be deployed between a retracted state and a deployed state during deployment of the hollow body (30). The distance separating the linking points (60A, 60B, 60C) in the deployed state of the threadlike link (68) is smaller than the distance separating these points (60A, 60B, 60C) in the totally dilated configuration of the hollow body (30) in the absence of threadlike link (68).Type: ApplicationFiled: October 12, 2007Publication date: May 1, 2008Inventors: Mikolaj Styrc, Eric Perouse

Publication number: 20080082166Abstract: This implant (10) comprises an endoprosthesis (30) having an axis (X-X?) which can be spontaneously deployed in a radial manner between a compressed configuration and a dilated configuration. The implant (10) comprises at least one radial runner (28) which comprises a separation surface (60) which extends radially with respect to an outer surface (42) of the endoprosthesis and a member (54) which can be deployed away from the axis (X-X?). The runner (28) is arranged so as to delimit a confinement housing (62) which extends between the separation surface (60) and the outer surface (42) and a radial spacer (65) which is defined by the separation surface (60) and the deployable member (54). When the implant (10) is retained in a state of radial compression, the maximum radial width of the housing (62) is less than the maximum radial width of the spacer (65) which is not equal to zero. Use in replacement of natural valves with endovalves.Type: ApplicationFiled: September 26, 2007Publication date: April 3, 2008Inventors: Mikolaj Styrc, Eric Perouse

Publication number: 20080077234Abstract: The inventive valve prosthesis (10) comprises a flexible plug (54) and an annular bearing reinforcement (12) which is embodied such that it is radially rigid and surgically implantable in the area of a heart valve. Said valve prosthesis is provided with an interchangeable prosthetic valve (50), is independent of the bearing reinforcement (12), endoluminally placeable and comprises a tubular support (52) which is radially deformable between a folded setting position and an unfolded position for implanting into a bearing structure and said flexible plug (54) connected to a tubular support (52). The bearing reinforcement (12) forms an annular support devoid of any plug capable to univocally limit a blood flow circulation.Type: ApplicationFiled: September 7, 2005Publication date: March 27, 2008Inventor: Mikolaj Styrc
