Cardiac injury device
A device, method, and use of a device for temporary management of a wound, such as a wound in a heart. The device has a shaft, a blood flow blocking membrane at the first end of the shaft for blocking blood flow through the wound, and an abutment member that is mounted to the shaft and is axially movable along the shaft towards and away from the blood flow blocking membrane for abutting the wound and holding the blood flow blocking membrane adjacent the wound. The blood flow blocking membrane is resiliently flexible and movable between at least a first collapsed state for inserting the blood flow blocking membrane through the wound, and a deployed state for blocking blood flow through the wound.
VASCULAR HOLE CLOSURE DEVICE
A device for closing an aperture in a vessel wall, the aperture having an external opening in an external region of the vessel wall and an internal opening in an internal region of the vessel wall. The device includes a covering member positionable inside the vessel against the internal opening of the aperture and having a dimension to prevent egress of fluid through the aperture. A securing member is positionable external of the vessel and has a plurality of pores extending therethrough. A flexible connecting member operatively connects the covering member and securing member and moves the securing member toward the covering member.
Off-Center Tissue Anchors
A tissue anchor system is provided that includes a first tissue anchor, a second tissue anchor that is separate and distinct from the first tissue anchor, and one or more tethers, which are configured to couple the first tissue anchor to the second tissue anchor. When the first tissue anchor is unconstrained, a head thereof is coaxial with an axis of a shaft thereof, and a tissue-coupling element thereof extends from a distal end of the shaft, is generally orthogonal to the axis, and is shaped such that if the tissue-coupling element were to be projected onto a plane that is perpendicular to the axis, at least 80% of an area of a projection of the tissue-coupling element on the plane would fall within a first angle of 180 degrees in the plane having a vertex at the axis. Other embodiments are also described.
Delivery system with anchoring nosecone and method of delivery
A delivery device includes an inner shaft, an outer sheath, a nosecone, and a tether component. The outer sheath is slidably disposed over the inner shaft. The nosecone is removably coupled to the inner shaft. The nosecone includes a delivery configuration for delivery to a treatment site, a radially compressed configuration in which a portion of the nosecone is configured to traverse through a heart wall, and a radially expanded configuration in which an outer surface of the nosecone contacts an outer surface of the heart wall. The tether component includes a first end coupled to the nosecone. The nosecone is configured to plug a piercing in the heart wall when in the radially expanded configuration.
SYSTEMS AND METHODS FOR TREATMENTING THE PATENT FOREMAN OVALE AND ATRIAL SEPTAL DEFECT
The present invention describes systems and methods for treating a hole in the septum, such as a patent foramen ovale or an atrial septal defect, with a closure implant designed to fluidly seal the hole to prevent blood from flowing between the right atrium to the left atrium. The closure implant includes two structures positioned on opposite sides of the hole in septum configured to close and seal the hole. The first structure is an expandable petal anchor having multiple petal groups with multiple petals of different sizes and/or shapes made of shape memory wire configured to be positioned on a distal side of the hole in the septum wall, and the second structure is a braided disk made of shape memory mesh positioned the proximal side of the hole in the septum wall, opposite the petal anchor. The braided disk is sized to cover the hole once it is expanded. The petal anchor is designed to pull and compress the braided disk against the septum wall to cover and fluidly seal the hole. The closure implant is designed to be delivered to the heart using a catheter-based delivery system.
Instrument and methods for surgically closing percutaneous punctures
A closure device for sealing a percutaneous puncture in a wall of a body passageway, the closure device including at least one of a toggle configured to engage an interior surface of the body passageway or a plug configured to engage an exterior surface of the body passageway and a guide wire configured to extend from an outside of the body to inside the body passageway, wherein at least one of the toggle and the plug is associated with the guide wire.
DELIVERY SYSTEM WITH ANCHORING NOSECONE AND METHOD OF DELIVERY
A delivery device includes an inner shaft, an outer sheath, a nosecone, and a tether component. The outer sheath is slidably disposed over the inner shaft. The nosecone is removably coupled to the inner shaft. The nosecone includes a delivery configuration for delivery to a treatment site, a radially compressed configuration in which a portion of the nosecone is configured to traverse through a heart wall, and a radially expanded configuration in which an outer surface of the nosecone contacts an outer surface of the heart wall. The tether component includes a first end coupled to the nosecone. The nosecone is configured to plug a piercing in the heart wall when in the radially expanded configuration.
INSTRUMENT AND METHODS FOR SURGICALLY CLOSING PERCUTANEOUS PUNCTURES
Methods for sealing a percutaneous puncture in a wall of a body passageway are disclosed herein. The methods include inserting a deployment instrument into the puncture via a toggle along the guidewire, and actuating the deployment instrument to move the first component and the second component relative to each other such that the toggle abuts the wall of the artery proximate the puncture to seal the puncture.
Occluder and Anastomosis Devices
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.
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.
