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.

Systems, devices and methods for reshaping a bodily lumen

A catheter includes a handle with torqueing and steering mechanisms. The torqueing mechanism includes a rotatable nosecone and a bearing coupled to the nosecone to be rotatable therewith. The bearing is concentrically disposed over a shaft of the catheter. The steering mechanism includes a rack coupled to the bearing to be slideable therewith and a pull wire having a proximal end attached to the bearing and a distal end attached to a distal portion of the shaft. Rotation of the nosecone causes an entire length of the shaft to rotate and axial movement of the rack tensions the pull wire to bend the distal portion of the shaft. A valve relief component is slidingly disposed over the shaft and is configured to dock onto the handle when not in use.

Catheter handle with torque mechanism and valve relief component

Devices including a capsule having an interior and a clamp assembly including a plurality of clamps. Each clamp includes a first arm having a first free end and a second arm having a second free end. The device includes a clamp assembly including a compacted state in which the plurality of clamps are compressed within the capsule and a deployed state in which at least the free ends of the plurality of clamps are positioned outside of the interior of the capsule. The first free end is closer to the second free end in the compacted state as compared to the deployed state. The device can further include a push rod releasably secured to the clamp assembly and a delivery rod releasably secured to the capsule. Methods of using the devices are also disclosed.

Ligating devices and methods for heart valve repair

A catheter based balloon enabled prosthetic heart valve delivery device is provided. The balloon enabled delivery device is configured to deploy a prosthetic heart valve through inflation. The balloon enabled delivery device is further configured to reduce or prevent migration of the prosthetic heart valve during deployment. Migration is prevented through a combination of balanced inflation of the balloon, inflation fluid flow balancing structures, retention rings, retention covers, and balloon surface treatments.

Balloon expandable transcatheter valve deployment devices and methods

Catheter apparatuses, systems, and methods for achieving renal neuromodulation by intravascular access are disclosed herein. One aspect of the present technology, for example, is directed to a treatment device having a multi-electrode array configured to be delivered to a renal blood vessel. The array is selectively transformable between a delivery or low-profile state (e.g., a generally straight shape) and a deployed state (e.g., a radially expanded, generally spiral/helical shape). The multi-electrode array is sized and shaped so that the electrodes or energy delivery elements contact an interior wall of the renal blood vessel when the array is in the deployed (e.g., spiral/helical) state. The electrodes or energy delivery elements are configured for direct and/or indirect application of thermal and/or electrical energy to heat or otherwise electrically modulate neural fibers that contribute to renal function.
