Abstract: A system for delivering an implant including a handle, a trigger, and an actuation assembly. The actuation assembly can include a planet carrier, at least one planet gear operatively coupled to the planet carrier, a sun gear shaft operatively engaged with the planet gear, a ring gear operatively engaged with the planet gear, a first clutch driver, and a second clutch driver. The actuation assembly can be configured to displace the outer tubular member in the proximal direction a distance (d) relative to the handle and to separately move the inner shaft member distally a distance (x) relative to the handle upon deployment of the trigger from a first position to a second position, and move the inner shaft member proximally a distance (y) relative to the handle with no displacement of the outer tubular member upon return of the trigger from the second position to the first position.

Abstract: A clip is provided for managing access through tissue. The clip is placed around an opening in tissue, although the opening may alternatively be formed after the clip is deployed. The clip can expand when medical devices are introduced through the clip and through the opening. When the medical devices are removed, the clip closed automatically to substantially close the opening.

Abstract: A coating device for coating a medical device with a drug-eluting material uses an in-process drying station between coats to improve a drug release profile. The drying station includes a heat nozzle configured for applying a uniform drying gas. A coating process using the dryer includes a closed-loop control for the gas between drying steps and an improved nozzle for producing more consistent spray patterns.

Abstract: The present disclosure is directed to multi-segment intraluminal guide wires including an elongate distal portion comprising a first metallic material (e.g., nitinol), an elongate proximal portion comprising a second metallic material (e.g., stainless steel). The distal and proximal portions may be directly joined together end to end by a solid-state weld joint. A diameter of the weld region surrounding the weld joint on either side of the weld joint may be reduced (e.g., ground down) relative to the diameter of the distal and proximal portions of the guide wire on either side of the weld region. A stiffness adjusting sleeve may be disposed over the weld joint so that a transition profile of bending stiffness across the weld region is gradual, rather than abrupt across the distal portion of the guide wire to the proximal portion of the guide wire. A polymer jacket may cover the sleeve and distal portion.

Abstract: A scaffold is formed by several segments joined or connected to each other by only at least one coupling. The coupling decouples the segments in the axial direction over a finite distance of axial displacement. The scaffold when implanted in a peripheral vessel reduces loading on rings of a segment due to the decoupling of the segments in the axial direction over the finite distance.

Abstract: A scaffold includes a radiopaque marker connected to a strut. The marker is retained within the strut by one or more of a mechanical interference fit, a polymer coating or melt, and/or by friction. The marker can take the form of a bead, rivet or snap-in marker, or a tube deformed when attached to the strut. The strut is made from a tube. The strut has a thickness of about 100 microns.

Abstract: The invention provides medical devices, systems and methods for tissue approximation and repair and in particular to reduce mitral regurgitation by means of improved coaptation. The devices, systems and methods of the invention will find use in a variety of therapeutic procedures, including endovascular, minimally-invasive, and open surgical procedures, and can be used in various anatomical regions, including the cardiovascular system, heart, other organs, vessels, and tissues. The invention is particularly useful in those procedures requiring minimally-invasive or endovascular access to remote tissue locations, where the instruments utilized must negotiate long, narrow, and tortuous pathways to the treatment site.
