    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.

    IPC: A61B17/04

    Abstract: A medical device for cutting a suture during a minimally invasive procedure may include an elongate shaft having a proximal end, a distal end, and a central longitudinal axis, a handle disposed at the proximal end of the elongate shaft, the handle including an actuation mechanism, and a cutting blade disposed proximate the distal end of the elongate shaft. The cutting blade is axially translatable within the elongate shaft in response to operation of the actuation mechanism. The elongate shaft includes a distal port to receive a suture. The elongate shaft includes a transverse slot extending inward from an outer surface of the elongate shaft generally perpendicular to the central longitudinal axis. The elongate shaft includes a suture lumen extending from the distal port axially within the elongate shaft to the transverse slot. The cutting blade intersects the transverse slot adjacent the suture lumen.
