20220370071 · 2022-11-24 ·

An implantable medical device for sealing and repairing defects in a body tissue or for creating an anastomosis includes a frame and a covering material. In some embodiments, the frame includes a single continuously wound wire that defines an apposition portion, a defect-occupying portion, and a sealing portion. In some embodiments, the tissue-sealing and anastomosis devices provided herein are well-suited for use in the GI tract including the small bowel and colon. In some embodiments, a two-part frame construct facilitates independent tailoring of apposition forces and radial forces exerted on tissues by the two-part frame.

OCCLUSIVE MEDICAL DEVICE WITH FABRIC RETENTION BARB

An occlusive implant system may include a catheter having a lumen extending from a proximal opening to a distal opening, a core wire slidably disposed within the lumen, and an occlusive implant having an expandable framework configured to shift between a collapsed configuration and an expanded configuration, and an occlusive element disposed on the expandable framework. The expandable framework may include a plurality of anchor members extending radially outward from the expandable framework, at least some of the plurality of anchor members each have a barb projecting circumferentially therefrom. The occlusive implant may be releasably connected to a distal portion of the core wire.

Variably bulbous vascular treatment devices

Vascular treatment and methods include a plurality of self-expanding bulbs and a hypotube including interspersed patterns of longitudinally spaced rows of kerfs. Joints between woven structures and hypotubes include solder. Woven structures include patterns of radiopaque filaments measureable under x-ray. Structures are heat treated to include at least shapes at different temperatures. A catheter includes a hypotube including interspersed patterns of longitudinally spaced rows of kerfs.

CLOSURE DEVICE SUITABLE FOR CLOSING THE ATRIAL APPENDAGE
20170340336 · 2017-11-30 ·

A medical closure device that is configured to be inserted into a patient's LAA (left atrial appendage) cavity comprises a closure member and at least one fixing member, wherein the closure member comprises a lid part and a body part one following the other in a proximal-distal direction. The lid part comprises a cover portion and a ring portion, the ring portion being configured to be circumferentially disposed along the rim of an individual LAA ostium, thus sealing the LAA ostium completely. The medical closure device is designed individually for each patient. A method of manufacturing the medical closure device includes the step of forming an LAA model based on computer graphic data of the patient. The LAA model is made by 3-D printing and is an exact reproduction of the patient's LAA. The medical closure device is then preformed using the LAA model.

Methods for occluding or promoting fluid flow
11672517 · 2023-06-13 ·

Devices and methods for occluding or promoting fluid flow through openings are disclosed. In one exemplary embodiment an occlusion device is provided having an expandable outer elongate tubular body, a guide member extending from a distal end of the outer body, and a slide tube disposed within the outer body, the proximal portions of the outer body and the slide tube being fixedly mated. The slide tube is configured to slide distally within the outer tubular body when the tubular body is expanded to form wings. A tether can be included as part of the device and it can be used to assist in positioning and locking a location of the device in an opening. Exemplary methods for delivering devices disclosed herein are also provided.

Occluder for occluding an atrial appendage and production process therefor

An occlusion device and a production process for it are described. The occlusion device consists of a mesh or braiding of at least one wire or thread wherein the occlusion device has been given a suitable design using a reshaping and/or heat-treatment process, is self-expandable, and is configured for secure anchoring in an atrial appendage of the left or right atrium of a heart. The occlusion device comprises a proximal retention region on a proximal end of the occlusion device a distal retention region and a central region between the proximal retention region and said distal retention region and wherein the occlusion device has a closed distal end without a holder, and wherein the occlusion device is at least partly of essentially spherical form, and hollow.

Expandable trans-septal sheath

Disclosed is an expandable transluminal sheath, for introduction into the body while in a first, low cross-sectional area configuration, and subsequent expansion of at least a part of the distal end of the sheath to a second, enlarged cross-sectional configuration. The sheath is configured for use in the vascular system and has utility in the performance of procedures in the left atrium. The access route is through the inferior vena cava to the right atrium, where a trans-septal puncture, followed by advancement of the catheter is completed. The distal end of the sheath is maintained in the first, low cross-sectional configuration during advancement to the right atrium and through the atrial septum into the left atrium. The distal end of the sheath is subsequently expanded using a radial dilatation device.
