SYSTEMS AND METHODS FOR PERCUTANEOUSLY SUPPORTING AND MANIPULATING A SEPTAL WALL
A catheter-based system for percutaneously supporting and articulating a septal wall of a heart includes a catheter and a flanged device. The flanged device includes a distal anchor and a proximal anchor, and has a radially collapsed configuration and a radially expanded configuration. When the flanged device is in the radially expanded configuration and disposed through a transseptal puncture in the septal wall, the flanged device is configured to anchor to the septal wall to permit manipulation thereof whereby an angle between an axis through the transseptal puncture and an axis through a native valve is reduced. The proximal anchor and the distal anchor may each be self-expanding or balloon expandable. The flanged device may further include a flanged device shaft. The flanged device shaft may be releasably coupled to the catheter.
Method and apparatus for cardiac procedures
Described herein are methods and apparatus for approximating targeted tissue using locking sutures. The locking sutures can be configured to receive suture ends that are interweaved through portions of the locking sutures. In a pre-deployment configuration, a locking suture can slide along suture tails and can be positioned at a target location within a target region. Once a desired position and/or tension is achieved, the locking suture can be transitioned to a post-deployment configuration where the locking suture constricts around the suture tails to inhibit relative movement between the suture tails and the locking suture.
MITRAL LEAFLET TETHERING
This disclosure includes apparatuses and techniques to access the right ventricle via trans-femoral vein threading a catheter or catheters to the apex or bottom of the right ventricle. Piercing through the venous or right side of the heart in the interventricular septal wall to access the left ventricle a catheter can be passed to turn upward pointing to the mitral valve. From this access point in the left ventricle the flail mitral leaflet can be sutured and tethered pulling it back into position and reattached with a grounding anchor in the right ventricle or imbedding the anchor into the septal wall. The interventricular septal wall crossing technique could include the passing of a coaxial catheter through the first access catheter where the first access catheter could act as a guide to direct the internal or second coaxial catheter toward the flail mitral leaflet.
Tethers For Prosthetic Mitral Valve
This invention relates to the design and function of a single-tether compressible valve replacement prosthesis which can be deployed into a beating heart without extracorporeal circulation using a transcatheter delivery system. The design as discussed combats the process of wear on anchoring tethers over time by using a plurality of stent-attached, centering tethers, which are themselves attached to a single anchoring tether, which extends through the ventricle and is anchored to a securing device located on the epicardium.

Synthetic chord for cardiac valve repair applications
Synthetic chord devices and methods for using the same for connecting tissues are provided. Aspects of the synthetic chord devices include a first flexible connector having first and second ends. Located at the first end is an attachment element that includes a tissue piercing member coupled to a securing member. The securing member includes an elongated shape memory coil that is present in a removable sheath configured to maintain elongation of the shape memory coil. A reinforcing element is located at the second end. The devices and methods of the invention find use in a variety of applications, such as cardiac valve, e.g., mitral valve, repair.
DEVICES, SYSTEMS AND METHODS FOR RESHAPING A HEART VALVE ANNULUS
Anchors for securing an implant within a body organ and/or reshaping a body organ are provided herein. Anchors are configured for deployment in a body lumen or vasculature of the patient that are curved or conformable to accommodate anatomy of the patient. Such anchors can include deformable or collapsible structures upon tensioning of a bridging element in a lateral direction, or segmented tubes that can be adjusted by tightening of one or more tethers extending therethrough. Such anchors can be used as a posterior anchor in a blood vessel in implant systems having a tensioned bridging element extending between the posterior anchor and an anterior anchor deployed at another location within or along the body organ. Methods of deploying such anchors and use of multiple anchors or multiple bridging elements to a single anchor are also provided.
Apparatus And Method For Delivering Surgical Tissue Connectors Into An Abdominal Cavity....
An apparatus and its method of use in delivering surgical tissue connectors into an area of the body and removing the surgical tissue connectors from the body area. The tissue connectors are connected to a base which allows for easy adjustment of the tissue connectors along a cord. The base includes a locking mechanism which impinges a sliding knot in the cord, and, in alternate configurations of the locking mechanism and knot, impinges on the sliding knot to prevent sliding in a loosening direction but allow sliding in a tightening direction, or allows sliding in a loosening direction.
Frustoconical Hemostatic Sealing Elements
A hemostatic tissue anchor (120) is provided that includes an anchor portion (130) supported at a distal end (192) of a generally elongate anchor shaft (132). A hemostatic sealing element (122) is coupled to and surrounds at least an axial portion of the anchor shaft (132), is configured to be disposed at least partially within a cardiac tissue wall (160) at a target site, and includes a self-expanding frame (124) attached to a sealing membrane (126). The hemostatic sealing element (122) includes an expandable portion (128) that assumes an expanded frustoconical configuration (138) that is defined by the self-expanding frame (124) and the sealing membrane (126), and acts as a hemostatic seal of an opening through the cardiac tissue wall (160), through which opening the anchor shaft (132) is disposed. Other embodiments are also described.
