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.

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: 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.

Abstract: Devices, systems, and method for adjusting and setting tension of an artificial chordae tendineae. The artificial chordae tendineae is coupleable between a leaflet clip and a tissue anchor. A locking assembly, through which the artificial chordae tendineae extends, is shiftable between a tension-adjusting configuration, in which the artificial chordae tendineae is movable to adjust tension on the leaflet, and a tension-setting or locked configuration, in which the artificial chordae tendineae is inhibited or prevented or locked against moving with respect to the locking assembly to set or fix tension on the leaflet.

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: A medical system includes an introducer device having an elongate shaft defining a shaft lumen and a hub secured to a proximal region of the elongate shaft. The hub includes a primary channel extending through the hub and fluidly coupled with the shaft lumen and a secondary channel extending through the hub and fluidly coupled with the shaft lumen. A guide catheter is adapted to be advanced through the secondary channel and into the shaft lumen. A guidewire is adapted to be advanced through the secondary channel and into the shaft lumen. A working catheter is adapted to be advanced through the primary channel and into the shaft lumen when the guide catheter is positioned with a distal end of the guide catheter within the secondary channel, the working catheter including a catheter shaft including a distal region that is adapted to releasably engage the guidewire.

Abstract: A medical device for cutting a suture during a minimally invasive procedure includes an elongate shaft, a handle housing disposed at the proximal end of the elongate shaft, and a cutting blade disposed proximate the distal end of the elongate shaft. A proximal portion of the handle housing includes an actuation mechanism including a lever arm having a first portion disposed outside of the handle housing and extending distally from the proximal portion of the handle housing. Translation of the first portion of the lever arm relative to the handle housing axially translates the cutting blade within the elongate shaft. A medical device system may include a stand configured to support at least one medical device and a medical device securable to the stand.

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: 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.
