Abstract: Various aspects of the present disclosure are directed toward implantable medical devices, systems, and methods for cardiac assistance.

Abstract: A self-expanding stent-graft provided in a diametrically compacted state for implantation and retained preferably by a constraining sheath, useful for the temporary or permanent repair of injured, partially or entirely transected body conduits including blood vessels. It may be used under direct visualization to quickly stop or substantially reduce loss of blood from such damaged vessels and to quickly re-establish perfusion distal to the injury site. The device would typically be implanted under emergency room conditions but also be used in field situations by trained medical technicians. After an end of the device is inserted into a blood vessel through the injury access, deployment preferably initiates from the device end in a direction moving toward the middle of the length of the device by directionally releasing the constraining sheath.

Abstract: Various features and associated advantages are described for diametrically adjustable support structures, adjustable valve structures, removable/replaceable valve structures, and associated systems and methods. Although some examples are directed toward prosthetic valve that is a conduit having a valve structure, or a “valved conduit” (e.g., used to replace a pulmonary valve and a portion of the corresponding pulmonary artery or an aortic valve and the aortic root), and other examples are directed toward prosthetic valves implanted native valve orifices (e.g., to replace an aortic or mitral valve), the features and advantages of the structures associated with those examples are interchangeable regardless of a particular application for which the examples are described.

Abstract: Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include device for chordae tendineae repair. The device may include a flexible cord having a first end and a second end; and a helical wire configured to attach to one of the first end and the second end of the flexible cord and anchor the flexible cord to a leaflet of a heart valve; and a capture device having a channel and configured to clamp the leaflet of the heart valve and deliver the flexible cord through the channel to anchor the helical wire to the leaflet.

Abstract: Various aspects of the present disclosure are directed toward apparatuses, systems and methods that include arranging an implantable flow restriction device within the aorta of a patient. The methods may also include physical dimensions of the implantable flow restriction device.

Abstract: The present invention provides methods and apparatuses for crossing or bypassing total or near total occlusions of vessels through the use of elongate members and specialized catheters that include a piercing catheter, a reentry catheter, a multi-lumen, reentry catheter, and combinations thereof. A piercing catheter comprises a distal tip used to pierce an occlusion in a crossing procedure and can be configured to microdissect the occlusion or provide support for an elongate member. A reentry catheter comprises a distal side port and ramp to facilitate the reentry or perforation of a vessel wall. A multi-lumen, reentry catheter comprises a tearable lumen divider and a distal side port and ramp.
