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 visualization catheter includes an elongate shaft, a cap portion, and an offset balloon coupled to the distal end of the shaft. The elongate shaft includes a proximal end, a distal end, and a central axis defined therebetween. The cap portion is coupled to the distal end of the shaft. The cap portion also includes a visualization element and defines an aperture. The offset balloon is coupled to the distal end of the shaft and encapsulates the cap portion. The offset balloon defines a center point offset relative to the central axis of the shaft.

Abstract: A steering system for a steerable flexible elongate member such as for delivering a medical device and/or system. The steering system may be configured for two-way or four-way steering. A control knob is rotatable to control steering of the steerable flexible elongate member in a first direction or a second direction within a steering plane. In a four-way steering system, a first control knob steers the steerable flexible elongate member in a first steering plane, and a second control knob steers the steerable flexible elongate member in a second steering plane transverse to the first steering plane. The steering system may be supported on a stand configured to allow rotational support of the steering system. The stand may support two steering systems in a manner allowing relative axial translation therebetween.

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.

Abstract: According to aspects of the present disclosure, a retrieval catheter assembly for retrieving an intragastric balloon may include a tubular member configured to pass through a wall of the intragastric balloon. The retrieval catheter assembly may also include a retrieval member coupled to the tubular member and movable between an undeployed configuration and a deployed configuration. In the undeployed configuration the retrieval member may be substantially aligned with the tubular member. In the deployed configuration at least a portion of the retrieval member may diverge from the tubular member and may be configured to engage the wall of the intragastric balloon.

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: 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 comprise an elongate shaft having a distal end region, a balloon coupled to the distal end region, and a force transmitting member at least partially disposed at least partially within the balloon. The force transmitting member may be designed to transmit energy to the lesion. The method may also include inflating the balloon to a first pressure, actuating the force transmitting member to at least partial break apart the lesion, and inflating the balloon to a second pressure greater than the first pressure.

Abstract: A delivery/deployment system having a control handle configured to control delivery and/or deployment of a medical device with arms configured to grasp tissue therebetween. The system may include a device spreader with arms engaging the medical device arms and controlled by an actuator operably coupled with the control handle. The control handle may include a lever pivotable to similarly pivot the device spreader and medical device arms open or closed. A device retention assembly may be provided to retain the medical device with respect to the device spreader. The control handle may include a release element movable to shift the retention assembly into a disengaged configuration allowing release of the medical device from the device spreader. The control handle may axially translate and/or rotate the device spreader into a desired position, and may be fixable in position by a handle lock once in a desired position.
