  • Publication number: 20090287196
    Abstract: A laser energy soft tissue aspiration device comprises a cannula defining an aspiration lumen and having one or more aspiration inlet ports at a distal end. A laser energy transmission guide delivers laser energy from the proximal end of the cannula to the distal end which can be inserted to a tissue removal site within a patient. Reciprocating longitudinal motion of the cannula along with suction provided within the lumen can cause soft tissue to be suctioned into the lumen for removal. Laser energy contained within the lumen and directed by an optical delivery system can ablate soft tissue pulled within the lumen. The optical delivery system can further protect the terminal point of the laser energy transmission guide, from which, the laser energy can be delivered.

  • Publication number: 20080103590
    Abstract: A method and device for reducing mitral regurgitation. An elongated body is positioned in a coronary sinus of a patient in a vicinity of a heart mitral valve posterior leaflet. The body is adapted to straighten a natural curvature of at least a portion of the coronary sinus in the vicinity of the posterior leaflet to move a posterior annulus anteriorly, which in turn moves the posterior leaflet anteriorly, thereby to improve leaflet coaptation.

  • Publication number: 20060004443
    Abstract: A novel system for performing a heart valve annuloplasty. The system involves the use of a plication band. In one embodiment, the annulus of the valve is reduced by constriction of the plication band itself. More particularly, each plication band enters the tissue at two or more points which are spaced from one other by a distance which is dictated by the geometry of the plication band. Subsequent constriction of the plication band causes these points to move toward each other, thereby constricting the tissue trapped between these points and thus reducing the overall circumference of the valve annulus. In a second embodiment, the annulus of the valve is reduced by linking multiple plication bands to one other, using a linkage construct, and then using a shortening of the length of the linkage construct between each plication band so as to gather the tissue between each plication band, whereby to reduce the overall circumference of the valve annulus.

  • Publication number: 20050165299
    Abstract: A method of performing a medical procedure on target tissue within the body includes immobilizing the target tissue with an immobilization device, positioning an insertion tool (e.g., a needle, a needle and marker wire, a needle gun, etc.) to be inserted into the target tissue on the immobilization device based on at least one reading of the target tissue, and inserting the insertion tool into the target tissue. An immobilization device for performing methods includes a frame assembly, a tissue immobilization assembly coupled to the frame assembly, the tissue immobilization assembly including a structure adapted to immobilize tissue, and a needle assembly releasably connectable to the frame assembly. The needle assembly includes a needle capable of being inserted into the immobilized tissue.

  • Publication number: 20050071000
    Abstract: Apparatus for reducing mitral regurgitation, including a bendable elongated body adapted to be inserted into the coronary sinus of a patient in the vicinity of the posterior leaflet of the mitral valve, the elongated body being adjustable between a first configuration adapted to be delivered into the coronary sinus and a second configuration adapted to exert a force onto the posterior annulus. The body includes a flexible spine having a proximal end and a distal end, and a flexible wire mounted on the spine and having a distal end fixed to the spine proximate to the distal end of the spine, and having a proximal portion extending from the proximal end of the spine. Axial movement of the wire causes a change in the spine from the first configuration to the second configuration to exert the force on the posterior annulus and thereby reduce mitral regurgitation.

  • Publication number: 20050055088
    Abstract: The present invention comprises a method for deploying an aortic valve prosthesis. This valve prosthesis may include any of the known aortic valves including, but not limited to, stented and unstented bioprosthetic valves, stented mechanical valves, and expandable or self-expanding valves, whether biological or artificial. The method involves the steps of: making a first opening leading to the left atrium; passing a valve prosthesis through the opening and into a cardiac chamber of the left side of the heart using a first manipulation instrument; making a second opening in the arterial system and advancing one end of a second manipulation instrument through the arterial opening and into the aforementioned cardiac chamber; securing the second manipulation instrument to the valve prosthesis; and using the second manipulation instrument to retract at least some portion of the valve prosthesis out of the aforementioned cardiac chamber.
