Abstract:
This invention is an occlusion device (10) for use in a body lumen such as the left atrial appendage (31). The occlusion device includes an occlusion member (11), and may also include a stabilizing member (12). The stabilizing member inhibits compression of the left atrial appendage, facilitating tissue ingrowth onto the occlusion member. The method of making the device includes forming a plurality of slots in a tube, the slots creating radially outwardly biased longitudinal elements (228). A membrane barrier (15) is then attached to the elements.
Abstract:
An example occlusive implant is disclosed. The example occlusive implant includes an expandable framework configured to shift between a collapsed configuration and an expanded configuration, an occlusive member disposed along at least a portion of the expandable framework and a sealing member disposed along the occlusive member, wherein the occlusive member includes at least a first cellular tissue growth pathway.
Abstract:
Disclosed herein are devices and methods for closing a left atrial appendage (LAA) that use an expandable disk having a deployment anchor and a plurality of closure anchors. The LAA closure devices are configured to expand to a diameter that is larger than a diameter of the LAA ostium. The deployment anchor attaches the disk to the tissue of the LAA that is everted or invaginated. The expandable disk causes the everted or invaginated LAA to expand and flatten within the left atrium of the heart. The closure anchors pierce the tissue of the LAA and engage the left atrial wall to close the LAA predominantly with its own tissue.
Abstract:
Treatment of an aneurysm (16) or other vascular defect can be facilitated or enhanced by an implant (95) delivered with a thermally activated detachment system. A delivery system (10) can include an implant (95) with a proximal portion (53) that defines a port (54). A pusher device (78) can include arms (82) extending distally from a junction (80) of the pusher device (78) and through the port (54), with distal sections (84) of the arms disposed within the implant (95). The arms (82) can, at a certain temperature, transition from engagement with the implant (95) to a shape that facilitates release of the implant (95). Additionally or alternatively, a coil (182) can engage an outer surface of the implant (95) at the proximal portion (53) and transition to a shape that facilitates release of the implant (95).
Abstract:
Various aspects of the present disclosure are directed toward apparatuses, methods, and systems as relating to occlusion. In certain instances, the apparatuses, methods, and systems may include a device for placement in vessels, appendages, and openings in a body. The device may include a unitary frame having a face portion that includes a center frame portion a plurality of elongate members.
Abstract:
A system for treating a tissue defect includes a delivery catheter extending longitudinally from a proximal end to a distal end and including a channel extending therethrough and a tissue closure device movably received with the channel of the delivery catheter to be delivered to target tissue to be treated in combination with a lumen extending within the channel to pass a sealant to target tissue.
Abstract:
Prosthetic heart devices may be implanted into the heart with a sensor (400) coupled to the device, the sensor being configured to measure physiological data, such as blood pressure, in the heart. Devices that may employ such sensors include prosthetic heart valves (100, 2000, 300, 4000) and occlusion devices (5000, 6000), although sensor systems may be deployed in the heart separate from other implantable devices. The sensors may include a body (402) with different configurations for attaching to the implantable device, such as apertures for sutures or fingers for connecting to structures of the implantable device. The sensors may provide data that allow a determination of aortic regurgitation or other information indicative of function of the implantable device and patient health during and after implantation of the device.
Abstract:
The present disclosure relates to devices and methods for forming occlusions. An occlusion forming device includes a delivery catheter and a magnetic component disposed a distance in a distal direction from a distal end of the delivery catheter. A connecting member extends between the magnetic component and the delivery catheter and is detachably coupled to the delivery catheter by a connector. The delivery catheter is configured to direct an occlusion forming, magnetic responsive fluid to a treatment site, where the magnetic component draws the fluid out and away from the distal end of the delivery device. The connecting member and magnetic component are configured to be detached from the delivery catheter so that the delivery catheter can be removed from the treatment site.
Abstract:
An implantable medical device for sealing and repairing defects in a body tissue or for creating an anastomosis includes a frame (1000, 100, 1410, 1610, 1810, 1910, 191, 1, 2210, 2310, 400, 700) and a covering material (1110, 1412, 1612, 1812, 1912, 210, 2214, 2314, 510, 810). In some embodiments, the frame (1000, 100, 1410, 1610, 1810, 1910, 191, 1, 2210, 2310, 400, 700) includes a single continuously wound wire that defines an apposition portion (1020, 120, 130, 1420, 1820, 1920, 1, 420, 720), a defect-occupying portion, and a sealing portion (1030, 130, 1430, 1830, 1930, 430, 730). In some embodiments, the tissue-sealing and anastomosis devices provided herein are well-suited for use in the Gl tract including the small bowel and colon. In some embodiments, a two-part frame (1000, 100, 1410, 1610, 1810, 1910, 191, 1, 2210, 2310, 400, 700) construct facilitates independent tailoring of apposition forces and radial forces exerted on tissues by the two-part frame (1000, 100, 1410, 1610, 1810, 1910, 191, 1, 2210, 2310, 400, 700)
