Abstract: Aspects of the disclosure provide a delivery device including a handle assembly as well as an inner catheter connected to the handle assembly. The inner catheter has a distal portion configured to receive an implant. The delivery device further includes an outer catheter connected to the handle assembly and coaxially positioned over the inner catheter. The delivery device also includes a capsule assembly including a proximal capsule secured to a distal end of the inner catheter. The capsule assembly also includes a distal capsule connected to a capsule shaft that extends within the inner catheter, the capsule shaft interconnecting the distal capsule to the handle assembly. The capsule assembly includes engagement features to releasably secure the distal capsule to the proximal capsule. Methods of loading and releasing an implant from a delivery device are also disclosed.

Abstract: Aspects of the disclosure include systems including an anchor including a body having a distal end, a proximal end and an opening extending from the proximal end to the distal end. The distal end includes a plurality of flanges, each flange including a proximal barb and a distal barb; the anchor having a natural arrangement in which the distal barbs of the plurality of flanges converge to form a pointed tip. The system further includes a rod that can be inserted in the opening to force the distal barbs away from a longitudinal axis of the opening into a delivery arrangement. The rod can also be used to retrieve an anchor after deployment. Such anchors can be utilized with annuloplasty implants. Methods of deploying and retrieving anchors of the disclosure are also disclosed.

Abstract: Aspects of the disclosure include bodily lumen reshaping and reduction systems, devices and methods. Such implants can include a plurality of anchors serially interconnected with a cinching member. Delivery devices of the disclosure are configured to deploy a first anchor into tissue. The delivery device can then deploy a second anchor and wind the cinching member around the second anchor to reduce a distance between the first and second anchors, placating the tissue between the anchors. Additional anchors can be similarly deployed and the cinching member can be similarly adjusted to reshape the lumen. Methods of deploying and reshaping a bodily lumen are also disclosed. In various examples, the bodily lumen is a heart valve, atrial appendage, portion of a gastrointestinal tract or urethra. Various embodiments include one or more anchors having a ratchet assembly or the like to substantially prevent the cinching member from unwinding.

Abstract: Aspects of the disclosure include systems and devices for delivering an annuloplasty implant and anchor delivery apparatus to a valve annulus. The systems and devices of the disclosure are configured to dispense and secure or anchor the implant to the valve annulus. Various implants of the disclosure include one or more cinching members that can be tensioned to reshape the valve annulus. Methods of deploying the implant, securing the implant to the valve annulus and reshaping the valve annulus are also disclosed.
