    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: The present invention provides methods and apparatus for obtaining endoluminal access. An elongate body is configured for insertion within a body lumen, conduit, organ, orifice or passageway, the elongate body having a working axis and a distal region, and an articulating element disposed near the distal region, the articulating element configured to articulate off-axis from the working axis of the elongate body. Methods of using apparatus of the present invention are also provided.

    摘要: Epicardial access and treatment systems are described herein where such devices may utilize multiple expanding frame members coupled to a flexible or rigid deployment catheter shaft. The multiple frame members may extend distally to collapse into a low-profile configuration and may further expand or open radially to create a working or surgical field under direct visualization and defined by the frame members and surrounding membrane while retracting any surrounding tissue. Moreover, the distal ends of each frame member may be tapered such that the frame members may close tightly relative to one another forming an atraumatic end. Any number of therapeutic tools can be passed through the catheter for performing any number of procedures on the tissue.

    摘要: A device for modifying one or more tissues in a patient's spine may include: an elongate, at least partially flexible body having a proximal portion and a distal portion, wherein at least the distal portion has dimensions that allow it to be passed into an epidural space and between target and non-target tissues of the spine; at least one movable blade disposed along one side of the elongate body; at least one actuator coupled with the at least one blade and disposed at or near the proximal or distal portion of the body for moving the blade(s) to modify one or more target tissues, wherein the at least one actuator is configured to move the blade(s) without significantly translating the elongate body proximally or distally; and means at or near the proximal and distal portions of the elongate body for facilitating application of at least one of anchoring force and tensioning force to the body to urge the at least one blade against the target tissue.
