Abstract: A heart valve anchor apparatus may include a body having a proximal portion and a distal portion. The body may include a first radially expandable portion at the proximal portion of the body, a second radially expandable portion at the distal portion of the body, and a root portion extending from the first radially expandable portion to the second radially expandable portion, the root portion having an outer extent. The first radially expandable portion may be configured to self-expand to an outer extent greater than the outer extent of the root portion when radially unconstrained. The second radially expandable portion may be configured to self-expand to an outer extent greater than the outer extent of the root portion when radially unconstrained. In an unstressed configuration, the body may define a longitudinal centerline that extends away from a plane tangent to the root portion.

Abstract: A heart valve anchor has a body that includes a distal portion, a distal end, a proximal portion, and a proximal end. The distal end and the proximal end define a longitudinal axis. The body has an expandable portion that includes a first radially expandable portion at the distal portion of the body, a second radially expandable portion at the proximal portion of the body, and a root portion disposed between the first and second radially expandable portions. The body has a first configuration adapted to be housed at least partially within a tissue penetrating device, and a second configuration in which the first and second radially expandable portions are partially or fully expanded such that the anchor engages tissue in a region between the first and second radially expandable portions.

Abstract: Anchor delivery systems and methods for repairing a valve inside a body, such as an atrioventricular valve, may include an anchor delivery device including a sheath for at least partially retaining an anchor in a collapsed form. The anchor delivery device may be configured to deliver the anchor to the atrioventricular valve. The anchor and an adjacent anchor may be connectable to each other in an expanded form, to link a series of anchors implanted at least partially around the atrioventricular valve. In some embodiments, the anchors may be connectable by a connecting member, such as a pledget, or a material disposable on a bulb of the anchor. In other embodiments, a bulb of the anchor and a bulb of the adjacent anchor may be configured to be directly interlocked.

Abstract: A catheter configured to dynamically compensate for the impact of internal and external forces that act upon the catheter during use is disclosed. The catheter may include sensors configured to measure received forces on control cables that extend within the catheter. A controller, coupled to the sensors, may record received force measurements associated with a working position of a distal end of the catheter. The controller may monitor subsequently received forces to identify force variances that may deflect the distal end of the catheter from its working position and may apply a driving force to one or more of the control cables to minimize the force variances. Monitoring received forces during use and applying compensating drive forces may reduce deflection of the distal end of the catheter, increasing the accuracy and precision of an annuloplasty procedure while minimizing potential damage to cardiac tissue.

Abstract: Anchor delivery systems and methods for repairing a valve inside a body, such as a heart valve, may include a delivery catheter having a distal end comprised of two or more rotatably coupled knuckles. An anchor delivery mechanism is disposed distally of the two or more knuckles, and includes a first pincer arm having a distal end and a proximal end rotatably coupled to a distal end of the anchor delivery mechanism at a first connection point, and a second pincer arm having a distal end and a proximal end rotatably coupled to the distal end of the anchor delivery mechanism at a second connection point opposite the first connection point. In a closed position, the distal ends of the first and second pincer arms are positioned together. In an open position, the distal ends of the first and second pincer arms are rotated apart from each other.
