20230049163 · 2023-02-16 · ·

During a medical procedure, a transseptal fenestration is made at a septum of the heart and a shunt is implanted into the transseptal fenestration. During the same medical procedure, a transapical puncture is made into a left ventricle of the heart. A prosthetic valve is delivered via the transapical puncture and implanted at a mitral valve of the heart. Subsequently to delivering the prosthetic valve and making the transseptal fenestration, the transapical puncture is closed. Other embodiments are also described.

ATRIAL SHUNT DECOMPRESSION DEVICE, WEAVING DEVICE AND WEAVING METHOD THEREOF
20230045035 · 2023-02-09 ·

An atrial shunt regulation device, a braid tool and a braid method thereof. The left disk (1) and the right disk (2) of the atrial shunt regulation device are connected via the intermediate portion (3) as a single piece, and the left disk (1), the intermediate portion (3) and the right disk (2) are braided by a single braid wire (10). The ends of the braid wires are secured by one nut in the single-braid method, which reduces the number and size of the nuts and easily forms a cortical layer. The braid tool for braiding an atrial shunt regulation device comprises a cylinder braid body mold (20), the cylindrical braid body mold (20) includes positioning pins (21) that are evenly connected to an outer wall of the braid body mold. The braid method of the atrial shunt regulation device comprises braiding, thermoforming, braiding a binding-off wire, securing ends of wires by a nut, and thermoforming again. The braid method is easy, the process is easy, and the device can be made manually in small batches to reduce costs.

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.

BIO-ABSORBABLE WOUND CLOSURE DEVICE AND METHOD
20180008249 · 2018-01-11 · ·

A wound closure device comprises a first frame and a flexible tubular section connected to the first frame, the first frame implantable through a wound in a patient's skin into a lumen of a blood vessel with a portion of the tubular section extending out through the skin. The tubular section has a first portion and a second portion, a wall of the tubular section defining a coaxial inner bore. Twisting the first portion relative to the second portion of the tubular section closes the bore is closed in an area of the tubular section between the first and second portions, thereby closing the wound. Also disclosed is an embodiment for closing an opening in a heart, as well as a delivery device, systems, and methods.

DEVICES AND METHODS FOR CLOSURE OF TRANSVASCULAR OR TRANSCAMERAL ACCESS PORTS

The present disclosure provides a variety of prostheses, delivery systems and techniques to facilitate closure of transvascular or transcameral access ports. Various embodiments of prostheses are provided including a plurality of radially expandable discs that can be filled with material to facilitate coagulation and to reduce or stop leakage from punctures in vessel walls.

Sealing device and delivery system

The invention relates to a sealing device for repair of cardiac and vascular defects or tissue opening such as a patent foramen ovale (PFO) or shunt in the heart, the vascular system, etc. and particularly provides an occluder device and trans-catheter occluder delivery system. The sealing device would have improved conformity to heart anatomy and be easily deployed, repositioned, and retrieved at the opening site.

Deflectable torque cable for delivery of medical devices

A delivery cable for delivering a medical device and a delivery device including the same are described herein. The delivery cable includes a flexible inner core, an outer coil surrounding at least a portion of the flexible inner core, and a pull wire disposed between the flexible inner core and the outer coil, the pull wire configured to deflect a distal deflectable portion of the delivery cable upon manipulation thereof. Methods of making the delivery cable and methods of using the delivery cable to deploy a medical device are also described herein.

Devices and Methods for Repairing a Pathological Connection Between Two Anatomical Structures

A device is disclosed for occluding an anatomical passage between first and second anatomical structures. The device includes a tip portion having a proximal element connected to a distal element through a member. The proximal element and/or distal element is movable axially along the tip portion while the other element preferably remains fixed in place. A handle is coupled to a proximal end of the tip portion through a shaft. The tip portion is positioned across the anatomical passage so that the proximal element occludes a first side of the passage and the distal element occludes a second side of the passage. A locking structure, such as a nut, is positioned or crimped against the proximal element, and, once done, the tip portion is released at the occluded passage.

EMBOLISATION SYSTEMS

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.
