Certain of the disclosed devices relate to RAMIN procedures ("remodeling and ablation using myocardial interstitial navigation"). RAMIN procedures, as described herein, represent a new family of non-surgical catheter-based procedures in order to accomplish ablation, drug delivery, re-shaping, pacing, and related structural heart interventional procedures, as desired.

Translation catheters, systems, and methods of use thereof

Номер: US20240122712A1
Принадлежит: Edwards Lifesciences Corp

Apparatus, for use at a valve of a heart of a subject, includes a first catheter, a second catheter, and a translation element. The translation element is connected to, and operatively joins, the distal ends of the first catheter and the second catheter. The translation element is operable to translate the distal ends laterally with respect to each other to transition the apparatus between (i) a first state in which the distal ends are held next to each other for transluminal advancement to the heart, and (ii) a second state in which the distal ends are spaced apart from each other for positioning at a first location on the annulus and a second location on the annulus, respectively. The apparatus is configured to, while in the second state, from the distal ends, anchor a first tissue anchor at the first location, and a second tissue anchor at the second location.

Tissue crossing system and anchor for use therewith

Номер: EP4009879A1
Принадлежит: Transmural Systems Llc

The present disclosure provides for novel ways of delivering tensioning elements, such as tethers, and deployable anchors, to a desired location within the anatomy of a patient. More specifically, the present disclosure provides a system and method for delivering deployable anchors to a desire location within the anatomy and tethering the anchors together through tissue. The deployable anchors may include anchors that have a pre-deployment elongate configuration and a post-deployment planar configuration.
