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: Devices, systems, and methods for delivery and deployment of an implantable device. The implantable device may be an anchor. The device includes an anchor garage configured to deliver the anchor, therein, to a target site, and an atraumatic shield movable with respect to the anchor garage. A biasing element biases the atraumatic shield into position with respect to the anchor garage. In some embodiments, the distal end of the anchor garage is a sharp tissue-penetrating end, and the atraumatic shield is biased distally over such sharp end. A limit stop may be provided to limit the extent to which the anchor garage extends distally, thereby limiting tissue penetration by the anchor garage and the depth of deployment of the anchor. An indicator may be positioned and/or configured to provide an indication of the relative positions of the anchor garage and the atraumatic shield.

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.

Abstract: A delivery/deployment system for delivering an implantable device within an implantable device housing and for deploying the implantable device from the implantable device housing. A stylet may be used to longitudinally advance or retract the implantable device with respect to the implantable device housing, such as to extend and deploy the implantable device from the implantable device housing. The delivery/deployment system has an implantable-device-extension-limiter arrangement configured to limit the distance which the implantable device may be extended from the implantable device housing. The delivery/deployment system optionally also has an implantable-device-rotation-limiter arrangement configured to limit rotation of the implantable device with respect to the implantable device housing.

Abstract: An introducer assembly is adapted for deploying a medical device. The introducer assembly includes an introducer body that is adapted to accommodate a volume of blood therein. An antechamber is coupled with the introducer body. A first hemostasis valve is disposed proximal of the antechamber and fluidly couples the introducer body with the antechamber. A second hemostasis valve is disposed distal of the antechamber and is adapted to allow the medical device to pass therethrough.

Abstract: A clip and a clip deployment and delivery system. The clip may be engaged with a clip spreader such that simple relative movement, such as sliding movement, between the clip and clip spreader causes the clip and clip spreader to disengage from each other. A clip spreader actuator may be coupled to one arm of the clip spreader, extend distally around a distal end of the clip spreader, proximally along the other clip spreader arm, and to a proximal end at which the actuator may be controlled to open or close the clip spreader. The clips may be leaflet clips having teeth on one arm thereof and bumps on another arm thereof. The arms of the leaflet clip may be biased into a closed configuration by a flex zone which has an expanded portion extending laterally away from only one of the clip arms.
