Abstract: A valve annulus repair system joins anchors at one or both of their proximal and distal ends to construct an implant to reshape the annulus. A removable frame may be used to position the anchors proximate to the annulus and to adjust the shape of the annulus. The frame may support the anchors during deployment of the system, release the anchors during construction of the implant, adjust the shape of the implant (and concomitantly the shape of the reconstructed valve) during an adjustment/cinching process, retain the adjusted shape of the valve annulus while relative anchor positions are secured, and release the anchors to enable the frame to be removed from the deployment site following implant construction. With such a system, a low-profile, flexile annular valve implant with reduced the risks of migration, fracture, embolism and thrombus may be provided.

Abstract: A retrieval device may include a sheath including a distal end and a proximal end, and an end effector at the distal end. At least a portion of the end effector may be movable relative to the sheath between extended and retracted states. The end effector may include a support member extending from the distal end of the sheath, and a movable member extending from the distal end of the support member. The device may include a handle assembly at the proximal end of the sheath, having an actuation member for transitioning the end effector between the extended and retracted states. The device may include a biasing member coupled to at least one of the actuation member and the sheath that may control a force, exerted by one of the movable members and the support member on the other, generated by relative movement between the movable and support members.

Abstract: A medical device may comprise a sheath configured to be inserted into a body lumen of a patient. A distal end of the sheath may include an elevator for changing an orientation of a medical device. A handle may include an actuator. The actuator may be operably connected to the elevator. Activation of the actuator may cause movement of the elevator. An engaging portion may, in at least one configuration of the handle, protrude from a surface of a handle body toward the actuator. A force exerted by the user on at least one of the actuator or the engaging portion may cause the handle to transition between (a) a first configuration in which the engaging portion interacts with the actuator to inhibit movement of the actuator relative to the engaging portion and (b) a second configuration in which the actuator is movable relative to the engaging portion.

Abstract: Systems and methods for processing electronic images from a medical device comprise receiving an image frame from the medical device, and determining a first color channel and a second color channel in the image frame. A location of an electromagnetic beam halo may be identified by comparing the first color channel and second color channel. Edges of an electromagnetic beam may be determined based on the electromagnetic beam halo, and size metrics of the electromagnetic beam may be determined based on the edges of the electromagnetic beam. A visual indicator on the image frame may be displayed based on the size metrics of the electromagnetic beam.

Abstract: A medical instrument may include a tube, a sheath provided around and coaxial with the tube, and an inflatable balloon at a distal end of the sheath. The balloon may receive a fluid from a lumen of the sheath, and may have a central opening along a longitudinal axis thereof, and into which the tube extends, a proximal portion, a middle portion adjacent to and distal of the proximal portion, and a distal portion adjacent to and proximal of the middle portion. When the balloon is inflated with the fluid, a maximum diameter of the middle portion may be less than a maximum diameter of the proximal portion, and less than a maximum diameter of the distal portion. The medical instrument may also include an extraction member provided at a distal end of the tube, distal to the balloon, and movable axially relative to the balloon.
