    摘要： Direct optical imaging of anatomical features and structures from within a biological organ in a dynamic environment (where the tissue being imaged is in motion due to cardiac rhythms, respiration, etc) presents certain image stability issues due (and/or related) to the motion of the target structure and may limit the ability of the user to visually interpret the image for the purposes of diagnostics and therapeutics. Systems and mechanisms for the purpose of actively stabilizing the image or for compiling and re-displaying the image information in a manner that is more suitable to interpretation by the user are disclosed.

    摘要： Devices for attaching a first mass and a second mass and methods of making and using the same are disclosed. The devices can be made from an resilient, elastic or deformable materials. The devices can be used to attach a heart valve ring to a biological annulus. The devices can also be used for wound closure or a variety of other procedures such as anchoring a prosthesis to surrounding tissue or another prosthesis, tissue repair, such as in the closure of congenital defects such as septal heart defects, tissue or vessel anastomosis, fixation of tissue with or without a reinforcing mesh for hernia repair, orthopedic anchoring such as in bone fusing or tendon or muscle repair, ophthalmic indications, laparoscopic or endoscopic tissue repair or placement of prostheses, or use by robotic devices for procedures such as those above performed remotely.

    摘要： A heart valve assembly includes an annular prosthesis and a valve prosthesis. The annular prosthesis includes an annular ring for dilating tissue within a biological annulus and a conformable sewing cuff extending radially from the annular member. The valve prosthesis includes a frame and a valve component. The annular ring is introduced into the biological annulus to dilate tissue surrounding the biological annulus and the sewing cuff conforms to tissue above the biological annulus. Fasteners are directed through the sewing cuff to secure the annular prosthesis to the biological annulus. The annular prosthesis may include a baleen element for biasing fabric on the annular ring outwardly to enhance sealing against the biological annulus. A valve prosthesis is then advanced into the sinus cavity, and secured relative to the annular prosthesis. The sewing cuff may enhance a seal between the valve prosthesis and annular prosthesis.
