  • Publication number: 20220287690
    Abstract: A method of collecting a biological sample inside a body cavity (18) using filaments (132). The body cavity (18) is accessed with the filaments (132) contained in a sheath (126) with ends thereof spaced apart from each other. To collect the sample, the filaments (132) are deployed outside the sheath (126) in the body cavity (18) and the ends of the filaments (126) are longitudinally brought closer to each other to bulge the portion extending therebetween to a radius larger than the radius of the sheath 126).

  • Patent number: 10004600
    Abstract: 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.

  • Publication number: 20130073023
    Abstract: A stent insertable in a body vessel, the body vessel defining a vessel wall. The stent includes a plurality of struts, the struts defining a substantially elongated stent passageway, the struts being configured, sized and operatively coupled to each other in a manner such that the stent is deformable between a first configuration and a second configuration. In the first configuration, the stent passageway has a first radial dimension and a first longitudinal dimension, and in the second configuration, the stent has a second radial dimension and a second longitudinal dimension, the second radial dimension being at least as large as the first radial dimension and the second longitudinal dimension being larger than the first longitudinal dimension. The stent is able to expand substantially longitudinally with the body vessel as the body vessel grows without reducing in diameter so as to reduce risks of damaging the vessel wall as the body vessel grows.

  • Patent number: 6736769
    Abstract: 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.
