Publication number: 20220273330Abstract: A method is described for shearing a tissue wall between a first cavity and an adjacent second cavity in a human or animal body. The tissue wall has a periphery forming an edge of an opening between the first cavity and the second cavity. A first member is placed into the first cavity, such that the first member is adjacent the wall. A second member is placed in the second cavity, proximate the first member. The first and second members have materials which magnetically attract one another. The first member and the second member are placed such that there is magnetic attraction between the first member and the second member through the wall and thereby compress an overlapping portion of the wall to create pressure necrosis. The first member and the second member are connected by a thread, wherein the thread extends over the edge of the opening.Type: ApplicationFiled: May 19, 2022Publication date: September 1, 2022Inventors: Nicolas CAUCHE, Orianne BASTIN, Jacques DEVIERE, Sonia DUGARDEYN, Ricardo RIO TINTO, Daniel BLERO, Cécilia DELATTRE, François HUBERLAND, Alain DELCHAMBRE

Patent number: 10022190Abstract: Force transducer (10) include two structural members (11, 12) spaced apart to define a gap (101) and being linked to each other. Optical fibers (13) are to the members and are freely suspended in the gap. The optical fibers are configured to provide a change in a detectable optical property responsive to a change in relative position between the two members in one or more predetermined degrees of freedom. Each of the optical fibers (13) is fixed to both structural members and continuous between the members to link the two structural members to each other. The optical fibers are substantially the only structure forming a link between the two structural members (11, 12), such that the arrangement of the optical fibers defines substantially the stiffness of the link between the two structural members in the one or more predetermined degrees of freedom, which stiffness is mainly, such as for at least 95%, determined by the optical fibers.Type: GrantFiled: April 2, 2013Date of Patent: July 17, 2018Assignees: UNIVERSITE LIBRE DE BRUXELLES, UNIVERSITE DE MONSInventors: Jean-Baptiste Valsamis, Nicolas Cauche, Jacques Deviere, Christophe Caucheteur, Valérie Voisin

Patent number: 10010702Abstract: A method of selective catheterism of in a network of conduits of an anatomical structure including inserting a flexible distal end of a guide for catheterism through the network of conduits. An appendage is attached on the distal end of the guide, the appendage includes a channel extending along a longitudinal axis of the guide. A catheter is slid along the catheter until a distal face of the catheter surrounding the guide engages a proximal surface of the appendage. A force oriented in a distal direction is exerted with the catheter on the appendage, which disengages the appendage from the distal end of the guide within the network of conduits. Navigation through the network of conduits is continued with the flexible distal end of the guide once the appendage is removed.Type: GrantFiled: May 8, 2017Date of Patent: July 3, 2018Assignee: UNIVERSITE LIBRE DE BRUXELLESInventors: Jacques Deviere, Nicolas Cauche, Alain Delchambre, Sonia Dugardeyn
