    摘要： 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.

    摘要： 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.

    摘要： 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.

    摘要： 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.
