FIXATION DEVICES, SYSTEMS AND METHODS FOR ENGAGING TISSUE
The invention provides devices, systems and methods for tissue approximation and repair at treatment sites. The devices, systems and methods of the invention will find use in a variety of therapeutic procedures, including endovascular, minimally-invasive, and open surgical procedures, and can be used in various anatomical regions, including the abdomen, thorax, cardiovascular system, heart, intestinal tract, stomach, urinary tract, bladder, lung, and other organs, vessels, and tissues. The invention is particularly useful in those procedures requiring minimally-invasive or endovascular access to remote tissue locations, where the instruments utilized must negotiate long, narrow, and tortuous pathways to the treatment site. In addition, many of the devices and systems of the invention are adapted to be reversible and removable from the patient at any point without interference with or trauma to internal tissues.
SUTURE SECURING ASSEMBLIES
A suture securing assembly comprises a two-bodied anchor and an associated delivery system which enhances fixation of a micro anchor in a bone hole or tunnel, as well as improving suture lock within bone. Initially, the two bodies are separated by a length of an inner shaft of the delivery system. The proximal body is fixed on the inner shaft of the delivery system and cannot move relative to the handle until after insertion into the bone, when the delivery system is disengaged from the anchor. The distal body further includes expansion wings and/or other features for increasing suture lock within the bone hole.
DEVICES AND METHODS FOR LUNG VOLUME REDUCTION
Methods of treating COPD, including bronchoscopically positioning a lung anchor in lung tissue, positioning an outer implant member in pleural space proximate the lung anchor, and coupling the lung anchor to the outer implant member and thereby compressing lung tissue.
Systems and methods for anchoring an implant
The invention relates in some aspects to a device for use in anchoring an implant, including anchors, sutures, implants, clips, tools, lassos, and methods of anchoring among other methods. Anchors as disclosed herein could be utilized to secure a coaptation assistance device, an annuloplasty ring, an artificial valve, cardiac patch, sensor, pacemaker, or other implants. The implant could be a mitral valve ring or artificial mitral valve in some embodiments.
Interventional medical systems and associated tethering assemblies and methods
In an interventional medical system, a delivery catheter for deploying a medical device of the system has a tethering assembly that includes a tether line, a grip member, and a release member, wherein the tether line extends through a longitudinal lumen of a base of the release member and is coupled to a base of the grip member, and the release member has legs extending though apertures formed through the base of the grip member. The device may be tethered to the catheter such that a proximal end of the device is held within a cavity defined by a plurality of elastic fingers of the grip member that extend distally from the base thereof; and the device may be deployed from the catheter by moving the legs of the release member within the grip member cavity to push the proximal end of the device out from the cavity.
AN EXPANDABLE FASTENER FOR ORTHOPAEDIC APPLICATIONS
The present disclosure provides an expandable fastener for orthopaedic applications and arranged for fastening when positioned in a bore hole in bone. The fastener comprises a body having an axis. The fastener further comprises an expansion portion moveable between a contracted configuration and an expanded configuration such that, in use, the expansion portion urges outwardly from the body towards the bone surrounding the bore hole. The fastener is arranged such that ingrowth of bone between the expansion portion and the body is substantially avoided when the expansion portion is in the expanded configuration.
