Abstract: A tether (10) can be transluminally advanced into a coronary blood vessel of the heart. At a first location (14a), a first terminus (10a) of the tether is advanced through a wall of the vessel into a chamber of the heart, and is then transluminally drawn out of the chamber such that a first segment of the tether extends from the first location through the chamber. At a second location (14b), a second terminus (10b) of the tether is advanced through the wall, into the chamber, and is drawn transluminally out of the chamber such that a second segment of the tether extends from the second location through the chamber. At least one anchor (50) is slid over and along at least one of the first and second termini and anchored to tissue of the chamber. The chamber can then be reshaped by modifying tension in the tether.

Abstract: Novel tools and techniques are provided for implementing protection of at least one tissue layer of a medical device or implant during crimping of the medical device or implant. In various embodiments, an implant tissue protection tool may include an outer portion configured to surround one or more outer segments of at least one tissue layer of a medical device to be implanted into a body of a subject and at least one protrusion (which may be affixed to a surface of the outer portion) configured to minimize or prevent occurrence (or likelihood of occurrence) of the at least one tissue layer (in some cases, leaflet material, or the like) of the medical device passing through at least one opening defined by a frame structure of the medical device during crimping of the medical device by a crimping device in preparation for implantation into the body of the subject.

Abstract: Mitral valve prolapse and mitral regurgitation can be treating by implanting in the mitral annulus a transvalvular implant. The transvalvular implant has a first end, a first anchoring portion located proximate the first end, a second end, a second anchoring portion located proximate the second end, and a central portion. The transvalvular implant can include a wire form curved body The transvalvular implant can include eyelets and the center of the transvalvular implant can include an opening. The central portion can be positioned so that it extends transversely across a coaptive edge formed by the closure of the mitral valve leaflets. Tricuspid regurgitation can be treated by implanting in the tricuspid annulus a transvalvular bridge. The transvalvular bridge can have a first anchoring portion and a second anchoring portion. The transvalvular bridge can positioned so that the bridge extends transversely across a coaptive edges formed by the closure of the leaflets. The transvalvular bridge can be positioned between a midpoint of the anterior annulus and straddling the commissure between the posterior annulus and the septal annulus. The transvalvular bridge can be anchored to the anterior annulus, the posterior annulus, and the septal annulus.

Abstract: Systems, apparatuses, and methods disclosed herein are provided for medical treatment, including treatment of dilated hearts (e.g., dilated left ventricle) or functional mitral valve regurgitation within a human heart. In instances, transcatheter medical treatments maybe utilized. The portion of the patient's heart maybe dilated due to a myocardial infarction or other cardiomyopathy. The treatment may comprise beating-heart repair of left ventricles with ischemic or non-ischemic dilated cardiomyopathy. The treatments may include approximating papillary muscles of the heart.

Abstract: Devices for treating a native valve annulus are disclosed herein. In some examples, the present technology includes a device comprising a plurality of arms configured to move independently of one another and a coupler coupled to the arms and configured to move relative to the arms. The device can further include a plurality of anchors, each carried by the distal portion of one of the arms and configured to engage tissue at or proximate the annulus. When the device is in a deployed configuration such that the arms extend axially and radially away from the coupler, movement of the coupler relative to the arms may decrease a circumferential distance between at least some of the anchors.

Abstract: An embolic filter positioning system includes a vascular delivery sheath, a filter catheter, a self-expanding embolic filter attached to a distal end of the filter catheter, and an elongate dilator having a tapered dilator tip. The elongate dilator is slidably received in a central lumen of the filter catheter, and the filter catheter is slidably received in the open lumen of the vascular delivery sheath. The tapered dilator tip is positioned distally of the distal end of the vascular delivery sheath, and the self-expanding embolic filter is radially constrained in a proximal portion of the open lumen of the vascular delivery sheath. The tapered dilator tip has an expanded configuration where it covers the open distal end of the vascular delivery sheath and facilitates entry though an arteriotomy and a contracted configuration where it can be retracted through the central lumen of the filter catheter..
