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: The present disclosure relates to delivery devices for transcatheter stented prosthesis loading, delivery and implantation. The delivery devices provide a loaded delivery state in which the stented prosthesis is loaded and compressed over the delivery device. The compression of the stented prosthesis can be adjusted with one or more elongate tension members, which extend around the stented prosthesis and proximately to an actuation and release assembly that can be provided as part of a handle assembly. The delivery device can be manipulated to adjust tension in the tension members to permit the stented prosthesis to compress, self-expand, and ultimately release from the shaft assembly. In some embodiments, the tension in one or more tension members is adjusted with one or more actuation and release assemblies.
