Abstract: 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.

Abstract: An assembly for anchoring in tissue may include an anchor part and a biasing part. The anchor part has a support made of a resilient material and at least two needles. The needles have a stem and a tip end configured to engage tissue. A portion of the stem is embedded in the support. The needles are allowed to be positioned according to a first configuration. A biasing part is configured to position the anchor part according to a second configuration differing from the first configuration in an orientation of the needles relative to one another. The biasing part includes holding means configured to hold the anchor part in the second configuration. The support is allowed to be deformed, thereby acting as a pivot when the needles change between the first configuration and the second configuration.

Abstract: The present disclosure relates generally to stents, systems, and methods for gastrointestinal treatment. In some embodiments, a stent may include a tubular scaffold having a first end opposite a second end, wherein a lumen extends between the first and second ends. The tubular scaffold may include a flared section and a medial section extending from the flared section, wherein a first diameter of the flared section is greater than a second diameter of the medial section. The stent may further include a liner extending partially along a surface of the tubular scaffold, wherein the liner is spaced from an anchoring region of the flared section to promote tissue ingrowth with the flared section.

Abstract: 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.

Abstract: 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.

Abstract: A device for supporting an endoscopic tool is disclosed comprising attachment means for attaching the device to an endoscope, a first guide tube having a distal open end and configured for accepting the endoscopic tool through it, first and second projecting members extending distally of the attachment means and being spaced apart when the device is attached to the endoscope to define a working space between them. The attachment means comprise first and second clamping members and at least one cable linking the clamping members. The cable is remotely actuatable for moving the clamping members relative to each other to adjust a spacing between them, accepting an endoscope. The cable allows for securing the clamping members to the endoscope. The first projecting member is attached to the first clamping member such that it has a fixed or at least one fixable position relative to the first clamping member, and the second projecting member is attached to the second clamping member.

Abstract: A guide is used for the selective catheterism of anatomic structures and for placing therapeutic instruments.

Abstract: An endoscopic surgical apparatus and endoscopic surgery methods comprise an anchoring means for anchoring a living tissue, and a piercing means for piercing the living tissue, each means being driven by an independent driving means. The anchoring means and the piercing means are able to move along parallel axes that extend outside a distal end of a catheter, allowing piercing a living tissue on a short length without having to fold the living tissue.
