  • Patent number: 11457930
    Abstract: An assembly including a bougie and a sheath for use in performing a gastroplasty for dividing a stomach of a patient into a sleeve receiving food and a bypass portion. The bougie includes an elongated body having a segment being shaped to follow a lesser curve of the stomach, and an extension member being movable within the stomach for positioning a distal portion thereof away from a gastroesophageal junction of the stomach and to define a fluid passage between the sleeve and the bypass portion. The sheath has an elongated main lumen in which the bougie is inserted and the sheath is translatable along the bougie to selectively expose the extension member of the bougie to perform its guiding action, or hide the extension member to ensure secure displacement of the bougie within the stomach and along the oesophagus.

  • Patent number: 11399815
    Abstract: Vascular closure devices and methods for closing a blood vessel puncture site disposed at a distal end of a tissue tract are described. A combination of the body's own natural mechanism with chemical and/or biological agents is relied upon to accelerate the hemostatic process. Included are steps of introducing a closure device through the tissue tract and deploying an expansible member at a distal end of the device within the blood vessel to occlude the puncture site. A sealing member disposed proximal the expansible member is then displaced by retracting and tensioning a coil spring so as to expose a chemical and/or biological region or release region of the device. The retraction and tensioning of the coil spring is limited by a coupling member. Exposure of blood and tissue to the chemical and/or biological sealing member promotes the clotting processing to accelerate the occlusion process in the tract.

    Abstract: A system for endoscopically forming an anastomosis between two naturally adjacent points in the digestive tract. The system utilizes elongate magnetic devices that, when connected across a tissue boundary, necrose tissue until an anastomosis forms and the devices are passed naturally. Despite the elongate shape of the devices, the resulting anastomosis is substantially round. As such, round anastomoses can be formed having increased diameters merely by increasing the lengths of the devices, obviating the need for wider endoscopes.

    Abstract: A shunt device for creating a shunt in an atrial septum includes magnets coupled to inner loops of a coil comprising at least two inner loops and two outer loops, with a diameter of each of the inner loops being less than a diameter of the outer loops. The coil is made of a shape memory alloy (SMA) and is adapted to exert a compressive force upon layers of tissue caught between the inner loops of the coil. The magnets are adapted to provide additional compressive force to adjacent inner loops of the coil, thereby further causing the coil to cut through the layers of tissue and create a shunt. The diameter of the resultant shunt is less than the diameter of the outer loops, thereby preventing the outer two loops from passing through the created shunt. At least one end of the coil has a connection means for connecting with a delivery device.

  • Patent number: 10813642
    Abstract: The invention is an implantable magnetic anastomosis device having an exoskeleton that directs self-assembly. The design allows the device to be delivered in a linear configuration using a minimally-invasive technique, such as endoscopy or laparoscopy, whereupon the device self-assembles into, e.g., a polygon. A coupled set of polygons define a circumscribed tissue that can be perforated, or the tissue can be allowed to naturally necrose and perforate. The device can be used to create anastomoses in a variety of tissues, such as tissues found in the gastrointestinal, renal/urinary, and reproductive tracts. New procedures for using anastomoses, e.g., surgical bypass are also disclosed.

  • Patent number: 10779945
    Abstract: Apparatus, systems, and methods are provided for repairing heart valves through percutaneous transcatheter delivery and fixation of annuloplasty rings to heart valves via a trans-apical approach to accessing the heart. A guiding sheath may be introduced into a ventricle of the heart through an access site at an apex of the heart. A distal end of the guiding sheath can be positioned retrograde through the target valve. An annuloplasty ring arranged in a compressed delivery geometry is advanced through the guiding sheath and into a distal portion of the guiding sheath positioned within the atrium of the heart. The distal end of the guiding sheath is retracted, thereby exposing the annuloplasty ring. The annuloplasty ring may be expanded from the delivery geometry to an operable geometry. Anchors on the annuloplasty ring may be deployed to press into and engage tissue of the annulus of the target valve.

  • Patent number: 10772638
    Abstract: An occluding device for occlusion of fluid flow through a lumen of a body vessel is manufactured by wedging fibers between adjacent coil windings of a primary coil so that the fibers extend generally radially across the primary coil body between the primary coil windings and outward therefrom. An elongated adhesive applicator is inserted into the primary coil lumen and subsequently proximally withdrawn while simultaneously depositing along the primary coil windings. The fibers and the adhesive are placed in overlapping locations so that the fibers extend through the adhesive. The fibers are thus blocked from slipping along their length relative to the coil body by the adhesive adhering to the fibers inside the primary coil lumen. The adhesive extends radially outward from the coil lumen no farther than the outer primary coil radius. The adhesive adheres to the fibers and may or may not adhere with the primary coil windings.

  • Patent number: 10716558
    Abstract: A tissue anchor includes a plate having a top surface and a bottom surface, and an array of first pins coupled with the plate, whereby each first pin includes an elongated shaft having a lower end with a first barb facing away from the bottom surface of the plate. The plate has an array of second pin apertures that are offset from the first pins, whereby each second pin aperture has a diameter that extends from the top surface to the bottom surface of the plate. The tissue anchor includes an array of second pins extending through the second pin apertures, whereby each second pin has an elongated shaft having an upper end including a second barb facing away from the top surface of the plate and a lower end including a stop that is located below the bottom surface of the plate. The elongated shafts of the second pins have outer diameters that are smaller than the diameters of the second pin apertures for allowing the elongated shafts of the second pins to slide within the second pin apertures.

  • Patent number: 10709451
    Abstract: A device for anastomosis of a tubular structure comprises first and second hollow members having a rigid part and an elastic part, and a connection member for interlocking the first and second members. The elastic parts are essentially circular rings, and are made of a polymeric, a biocompatible and/or biodegradable material. The rigid parts have an outer surface that is partly semi-circular in cross section, wherein the diameter at a non-connecting end is larger than or equal to the diameter at a connecting end, which ends in an edge. The first and second members are connected to each other so that a distance is formed between the elastic parts. A cavity is formed between the rigid parts and the connection member and the tubular structure, when arranged in the device.
