A bristle device for delivery into a body lumen comprises a longitudinally extending stem 1 and a plurality of bristles extending generally outwardly from the stem for anchoring the device in a body lumen. There may be at least two bristle segments and in some cases there are flexible sections between the segments. The flexible sections articulate to enable the device to pass through a catheter placed in a tortuous anatomy or to be deployed in a curved vessel, or across a bifurcation. In some cases at least some of the bristle segments are spaced-apart to accommodate bending of the bristles.

An in-tube transit object that is inserted in a tube includes: a coil section formed by winding a wire; and a fiber section attached to an end on one side and an end on the other side in a winding-axis direction of the coil section. The coil section is formed with a large diameter section, through which fiber of the fiber section is inserted, at the end on the one side and the end on the other side, and is inserted in an extending state in the winding-axis direction when the in-tube transit object is inserted into the tube. The fiber section is configured to expand when seen in the winding-axis direction in the case where the in-tube transit object is inserted in the tube and then discharged from the tube, which brings the coil section into a compressed state in the winding-axis direction.

An interatrial shunting device including a tube and an anchoring assembly. The tube defines a first end opposite a second end, and a tube wall extending to and between the first and second ends. The tube wall is a solid body and defines a lumen of the tube, with the lumen being open at the first and second ends. The anchoring assembly is carried by the tube and is configured to secure the interatrial shunting device to a native atrial septum. The solid wall tube prevents tissue overgrowth across the atrial septum, and can have minimal exposure of the device in the left atrium to minimize stroke and other risks. In some examples, the anchoring assembly is configured to be self-transitionable from a delivery state to a deployed state.

Systems, devices, and methods for controlling cooperative surgical instruments with variable surgical site access trajectories are provided. Various aspects of the present disclosure provide for coordinated operation of surgical instruments accessing a common surgical site from different approach and/or separate body cavities to achieve a common surgical purpose. For example, various methods, devices, and systems disclosed herein can enable the coordinated treatment of tissue by disparate minimally invasive surgical systems that approach the tissue from varying anatomical spaces and must operate differently, but in concert with one another, to effect a desired surgical treatment.

Apparatus and methods are described herein for anchoring a prosthetic heart valve. In some embodiments, an apparatus includes a tether attachment member that includes a base member that defines at least a portion of a tether passageway through which a portion of a tether extending from a prosthetic heart valve can be received therethrough. The base member defines a locking pin channel that intersects the tether passageway. A locking pin is disposable within the locking pin channel and movable between a first position in which the locking pin is at a spaced distance from the tether passageway, and a second position in which the locking pin intersects the tether passageway and can engage the portion of a tether disposed therein to secure the tether to the tether attachment member.

The techniques of this disclosure generally relate to a method including navigating an adhesive catheter to a proximal end of a false lumen of a dissection. The false lumen is defined by a septum and a vessel wall. The method further includes delivering an adhesive from the adhesive catheter to the proximal end of the false lumen. The adhesive is compressed between the septum and the vessel wall to close the false lumen.

The present invention relates to a medical implantable interatrial septal defect occlusion device to occlude the congenital cardiac malformations such as Atrial Septal Defect (ASD) and Patent Foramen Ovale (PFO) providing hemodynamics between two atria. The occlusion device includes distal and proximal discs having expandable shape memory characteristics, pre-created sealed potential fenestrations which are sealed with biocompatible polymeric patch and sutures to be perforated and used for any possible intervention needed.

A clip for reducing a dimension of an opening in tissue may include a continuous member having a plurality of legs and a plurality of preformed bends connecting adjacent legs, wherein the plurality of legs form: a first group having two protrusions; a second group having two protrusions; and a third group having two protrusions, wherein each protrusion of each group includes two legs of the continuous member and a corresponding preformed bend connecting the two legs, and each protrusion of each group extends from a region adjacent a first end of the clip to a region adjacent a second end of the clip.

An medical implantable occlusion device (100) is disclosed having a collapsed state and an expanded state and comprising a braiding (101) of at least one thread, and a distal end (102) comprised of said braiding. The distal end comprises loops (103, 104, 204, 304) formed by loop strands (105, 106, 206, 306) of the at least one thread, wherein, at least in said expanded state, each loop strand has a curved shape and extends away from a centre point (117) of the distal end, whereby an apex point (107, 108, 208, 308) of each of the loop strands corresponds to the turning point of the curved shape and to the point of each of the loop strands being arranged closest to the centre point. At least one of the loop strands is displaced from the centre point by a centre distance (109, 110, 210, 310), and the apex point lie at a distance from a periphery (113) of the distal end.

The disclosed technology provides a device for sealing an aperture in a tissue of a body lumen. The device comprises a flexible support member having a base having (i) a central portion and (ii) one or more lateral support portions, to engage and/or hold a sealable member of the device against an interior surface of the tissue when the device is in the sealing position. The lateral support portions provide additional support surfaces to engage peripheral portions of the sealable member against the interior surface of the tissue.
