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: 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.

Abstract: The present disclosure relates generally to the field of medical devices for clamping a leaflet of a heart valve. In particular, the present disclosure relates to medical devices, systems, and methods for delivering artificial chordae tendineae in a patient. In an embodiment, a system may include a clamp having a plurality of arms at a first end. The plurality of arms may have a closed configuration in which the arms are oriented toward each other, and an open configuration in which the arms are oriented away from each other. A spring portion may be coupled to the plurality of arms at a second end that is configured to bias the arms to the closed configuration. The arms of the clamp may be configured to fixedly engage with a leaflet of the heart valve. The second end of the clamp may be configured to couple to an artificial chordae tendineae.

IPC: A61F2/24
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 delivering artificial chordae tendineae in a patient. A system for adjusting tension in an artificial chordae tendineae includes an artificial chordae tendineae coupleable between a clip and an anchor. The clip is engageable with a leaflet of a heart valve while the anchor is engageable with a papillary muscle or heart wall. The anchor includes a body portion, and a locking portion coupleable with the artificial chordae tendineae and configured to allow movement of the artificial chordae tendineae in a first direction while preventing movement of the artificial chordae tendineae in a second direction opposite the first direction. An actuator is coupled to the locking portion for selectively releasing the locking portion to enable selective movement of the artificial chordae tendineae in the second direction.

Abstract: Medical devices and method for making and using medical devices are disclosed. 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 a cavitation member disposed within the balloon. The method may also include inflating the balloon to a first pressure, activating the cavitation member, and inflating the balloon to a second pressure greater than the first pressure.

Abstract: Tissue regions are treated using a multiple lead electrode probe. A plurality of electrodes may be disposed about an elongate shaft. The elongate shaft may be slidably disposed within a lumen of a delivery sheath. One or more probes including one or more electrically active regions may also be slidably disposed within the delivery sheath. The one or more probes may be configured to extend radially about the elongate shaft. The plurality of electrodes and the electrically active regions may be individually connected to a control and power unit through individual channels.

Abstract: According to one aspect, a visualization device may include an image sensor, a lens for focusing light onto the image sensor, a first end, a second end opposite the first end, a lateral wall surface extending between the first end and the second end, and a coating on the lateral wall surface. The coating may include at least one of an electrically-insulating layer and a light-blocking layer, and may be deposited on the lateral wall surface using, for example, physical vapor deposition (PVD).
