Patent number: 10004600Abstract: A device for supporting soft tissue includes a tubular body and is constituted of a sequence of compliant portions and anchoring portions. The anchoring portions each include anchor members adapted to penetrate into soft tissue. The compliant portions each include deformable members extending between ends of the compliant portion, at least one of a distance and orientation between said ends being adjustable by application of a force on the tubular body. The tubular body includes a ring-like shape reached at least by deformation of the compliant portions, the ring-like shape having the anchor members of the anchoring portions protruding circumferentially along a direction defined by a vector having a component being at least tangential to the curve of the ring-like shape, for the anchor members to penetrate the soft tissue. A method for anchoring the device to soft tissue is also provided.Type: GrantFiled: May 2, 2013Date of Patent: June 26, 2018Inventors: Renzo Cecere, Rosaire Mongrain, Toufic Azar, Jorge Angeles, Jozsef Kovecses

Patent number: 6736769Abstract: To determine a coefficient of diffusion of a radioisotope in a radioisotope-containing implant structure and to calculate a quantity of radioisotope to be introduced in an implant structure in view of administering to a vascular region of a patient's body a dose of radioactivity at a given dose rate, a relation is calculated between a coefficient of diffusion of the radioisotope in the implant structure and a coefficient of diffusion of the radioisotope in the vascular region of the patient's body for at least one given period of time during which the radioisotope has to be released. The diffusion coefficient of the vascular region is determined. The method also determines, from the diffusion coefficient of the vascular region and in connection with the above relation, the diffusion coefficient of the implant structure required to release the radioisotope within the given period of time.Type: GrantFiled: May 9, 2001Date of Patent: May 18, 2004Inventors: Olivier Bertrand, Rosaire Mongrain
