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: An example method for treating a blood vessel may include disposing a medical device within the blood vessel at a position adjacent to a lesion. The medical device may include an elongate shaft having a distal end region, a balloon coupled to the distal end region, and an iron-containing fluid disposed within the balloon. The method may also include inflating the balloon to a first pressure, delivering a plurality of electromagnetic pulses to the iron-containing fluid, and inflating the balloon to a second pressure greater than the first pressure.

Abstract: An aortic arch embolic protection device may include an anchoring structure including a first anchoring ring at an upstream end and a second anchoring ring at a downstream end. A first filter element may extend from the first anchoring ring to the second anchoring ring and define a lumen through the aortic arch embolic protection device. A second filter element may be disposed within the lumen of the first filter element, wherein the second filter element includes an access port configured to facilitate passage of an interventional catheter through the access port. The anchoring structure may include a tubular scaffold extending from the first anchoring ring to the second anchoring ring. The second filter element may extend from the second anchoring ring upstream to the access port. The second filter element may extend transversely across the lumen of the first filter element at a plurality of axial locations.

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 valve fixation device may comprise a unitary elongate member that is biased towards a closed configuration wherein at least a pair of tissue engaging surfaces of the elongate member are held adjacent to each other by a bias force. The bias force is at least equal to a valve leaflet grasping force, enabling the fixation device to grasp and retain leaflets as part of cardiac treatment. A delivery tool including a spreader may independently translate the tissue engaging surfaces to enable cardiac leaflets to be captured and retained by and/or between the tissue engaging surfaces. The valve fixation device may include at least two arms, each of which may be independently controlled to grasp and capture opposing leaflets of a valve, such as the anterior and posterior leaflets of a mitral valve, to reduce the size of the valve opening and improve cardiac performance.

Abstract: The present disclosure relates generally to the field of medical devices for delivering artificial chordae tendineae in a patient. In an embodiment, an anchor is movable between a delivery configuration and a deployed configuration, the anchor being in the delivery configuration when disposed within a delivery catheter, the anchor being in the deployed configuration when the anchor is moved beyond a distal end of the delivery catheter. When the anchor is in the delivery configuration it has a first outer dimension and when the anchor is in the deployed configuration it has a second outer dimension, the first outer dimension being smaller than the second outer dimension. The anchor is engageable with a papillary muscle or a heart wall when the anchor is in the deployed configuration and is also coupleable to an artificial chordae tendineae to anchor the artificial chordae tendineae to the papillary muscle or heart wall.

Abstract: The present disclosure relates generally to the field of medical devices for treating heart disease. In particular, the present disclosure relates to medical devices, systems, and methods for delivering artificial chordae tendineae in a patient. A system for delivering a chordae tendineae into a heart may include a delivery catheter. A clamp catheter may be configured to translate through the delivery catheter. A spreader may be disposed on the clamp catheter. A first clamp may be at least partially contained in the spreader in a closed configuration and may be attached to the chordae tendineae. An anchor catheter may be configured to translate through the delivery catheter and may have an anchor attached to the chordae tendineae. A sheath may be extended over the anchor catheter and anchor and may be configured to restrain an arm of the anchor.
