  • Publication number: 20180000588
    Abstract: Methods and systems for improving the competency of a venous valve wherein one or more compressor(s) (e.g., space occupying material(s) or implantable device(s)) is/are delivered to one or more location(s) adjacent to a venous valve to compress the venous valve in a manner that causes one or both leaflets of the valve to move toward the other, thereby improving closure or coaptation of the valve leaflets. The compressor(s) may be delivered by an open surgical approach, by a direct percutaneous approach or by a transluminal catheter-based approach.

  • Patent number: 8998933
    Abstract: A surgical fastener clip for proximating tissue, the clip providing an undeflected state in which the clip comprises a center portion, a first leg, and a second leg. The center portion has a perimeter defining a circle-like shape. The legs project outwardly relative to the perimeter from a point of departure to a tip. Extension of each of the legs relative to the perimeter defines an identical wind direction that is either clockwise or counterclockwise. The clip optionally includes a linear cross-member extending across the perimeter. The surgical clip can be formed by a wire that is partially wound onto itself in a spiral-like fashion, with the center portion and the legs being co-planar in the undeflected state. During use, the clip is rotated, drawing tissue into the center portion. Systems incorporating the clip are also provided.

  • Patent number: 8454683
    Abstract: A system for modifying a heart valve annulus includes a helically helical anchored annuloplasty device delivered to the annulus via an elongated delivery member. The helical anchors of the devices disclosed herein are rotated into the valve annulus along an anchor guide by using a driver that is movably disposed in the delivery member. A tether is disposed within an inner channel of the helical anchor and a locking device is used to secure the annuloplasty device after the valve annulus has been modified. The annuloplasty device can be delivered to the annulus using, traditional surgical approach or a minimally invasive or catheter based methods.

  • Patent number: 7655040
    Abstract: A catheter-based, annulus reduction device and system for cardiac valve repair and method of using the same. The system is usable for treating mitral valve regurgitation and comprises a catheter, a reduction ring carried within the catheter, the reduction ring including a plurality of exit ports formed in a side wall of the reduction ring and filament received in the reduction ring. The filament includes a plurality of radially extendible barbs corresponding to the sidewall openings. The reduction ring carrying the filament is deployed adjacent a mitral valve annulus and the filament is translated relative to the reduction ring to deploy the barbs through the exit ports and into the annulus and to further translate the reduction ring with deployed barbs to reshape the annulus.

  • Publication number: 20080269876
    Abstract: Incompetency or regurgitation of a cardiac valve is treated by injecting a space occupying material or implanting a space occupying device within a papillary muscle or in heart tissue near a papillary muscle to cause lengthening or repositioning of the papillary muscle in a manner that improves coaptation of the valve leaflets and lessens valvular incompetency or regurgitation. The procedure may be performed by open thoracotomy, thoracoscopically, by a tran-endocardial catheter based approach or by a trans-coronary catheter based approach.

  • Publication number: 20080249618
    Abstract: Incompetency or regurgitation of a cardiac valve is treated by injecting a space occupying material(s) or implanting a space occupying device(s) at an interstitial location adjacent to the valve such that the space occupying material or device exerts pressure on the valve causing one or more leaflets of the valve to be favorably repositioned. The procedure may be performed by open thoracotomy, thorascopically or transluminally using a tissue penetrating catheter.

  • Patent number: 7316706
    Abstract: A system for treating mitral valve regurgitation comprises a tensioning device slidably received within a delivery catheter. The tensioning device includes a tether linking proximal an anchoring member and a distal anchoring member. At least one of the anchoring members includes an elastic portion that flexes in response to a heartbeat when the tensioning device is positioned across a chamber of a heart. The tether includes at least one locking member initially positioned between the anchoring members. A method for treating mitral valve regurgitation comprises piercing a first wall of a chamber of a heart, engaging a distal anchoring member with a second wall of the heart chamber, engaging a proximal anchoring member with the first wall, and pulling a locking member affixed to a tether linking the anchoring members from an initial position between the two anchoring members to a locked position proximal the proximal anchoring member.
