20080288061Solid Construct Mitral Spacer - A heart valve implant according to one embodiment may include a shaft extending generally along a longitudinal axis of the heart valve implant having at least one anchor configured to be coupled to a first end of the shaft. A spacer may include a plurality of individual segments each including at least one passageway configured to be disposed about the shaft. The plurality of individual segments may define an outer surface of the spacer which is configured to interact with at least a portion of at least one cusp of a heart valve to at least partially restrict a flow of blood through the heart valve in a closed position. The plurality of individual segments may each having a length and at least one cross-section dimension no larger than an internal cross-section of a lumen of a delivery catheter.11-20-2008
20090043382Mitral Spacer - A heart valve implant may include a shaft and an anchor configured to be coupled to an end of the shaft. A spacer may be coupled to a portion of the shaft and comprise a plurality of individual segments including a first and at least a second individual segment. The first segment may be coupled to the shaft. The second segment may be coupled to at least a portion of an exterior surface of the first segment and may have at least one cross-section dimension which is greater than an internal cross-sectional dimension of a delivery lumen. Additional segments may be coupled to an inner, adjacent segment. The segments may include a collapsible body portion to facilitate percutaneously delivery through a lumen. The segments may define an outer surface of the spacer configured to interact with at least a portion of at least one cusp of a heart valve to at least partially restrict a flow of blood through the heart valve in a closed position.02-12-2009
20090048668System and Method for Implanting a Heart Implant - A method and system according to one embodiment may include a plurality of apparatus configured to percutaneously deliver a heart valve implant. The method and system may include an implant comprising an anchor configured to engage cardiac tissue, a shaft coupled to the anchor, and a valve body coupled to the shaft. The method and system may further include at least partially collapsing the heart valve implant and percutaneously inserting the heart valve implant into a heart. The percutaneously inserted implant may be secured within the heart and may then be expanded.02-19-2009
20090131849Heart regurgitation method and apparatus - A regurgitation implant may comprise a conduit or straw which may be coupled to a shaft. The shaft may be coupled to at least one anchor portion configured to couple the regurgitation implant to native coronary tissue. At least a portion of the conduit may be configured to be disposed proximate a mitral valve such that the regurgitation implant may interact and/or cooperate with at least a portion of the native mitral valve to induce a controlled amount of regurgitation through the conduit and therefore through the mitral valve. The regurgitation through the conduit and the mitral valve may cause the heart to dilute in a manner that is generally consistent with advanced disease of the heart. The amount of regurgitation may therefore be adjusted depending on the desired condition of the heart.05-21-2009
20090132033Implant Delivery System and Method - An implant delivery system may comprise a catheter including at least one lumen, a guide wire configured to be received in the lumen, and an implant. The guide wire may comprise a clamping mechanism disposed about a distal end of the guide wire. The clamping mechanism may include a first and at least a second jaw wherein at least one of the jaws is configured to pivot between a closed position wherein the jaws define at least one internal cavity between the jaws configured to receive at least a portion of the implant and an open position configured to release the implant. The implant may be configured to be received in the lumen and may comprise a driver configured to be releasably received in the cavity of the clamping mechanism.05-21-2009
20090264879Fluid-Assisted Medical Devices, Systems and Methods - Surgical devices, systems and methods for treating tissue are provided. Also provided are systems for treating tissue and methods of treating tissue. An exemplary surgical device comprises a handle (10-22-2009
20100324668Mitral Spacer - A heart valve implant may include a shaft and an anchor configured to be coupled to an end of the shaft. A spacer may be coupled to a portion of the shaft and comprise a plurality of individual segments including a first and at least a second individual segment. The first segment may be coupled to the shaft. The second segment may be coupled to at least a portion of an exterior surface of the first segment and may have at least one cross-section dimension which is greater than an internal cross-sectional dimension of a delivery lumen. Additional segments may be coupled to an inner, adjacent segment. The segments may include a collapsible body portion to facilitate percutaneously delivery through a lumen. The segments may define an outer surface of the spacer configured to interact with at least a portion of at least one cusp of a heart valve to at least partially restrict a flow of blood through the heart valve in a closed position.12-23-2010
20110319889Electrode Sheath For Electrosurgical Device - This invention provides an electrosurgical device comprising a handle, a shaft member distal to the handle, a first electrode tip and a second electrode tip at a distal end of the shaft member with the first electrode tip laterally spaced from the second electrode tip, and an electrode sheath movable to cover and uncover a side of the electrode tips while a distal end of the electrode tips is uncovered to treat tissue.12-29-2011
