Abstract: An assembly and method for end-to-side connection to anatomical tissue is disclosed. The system and method are particularly useful in coupling a ventricular assist device pump to an aorta. The assembly and method include using a tubular graft member coupled to a connection ring having at least one of a plurality of distally projecting tines extending from a distal aspect of the connection ring, and a stent having a distal flange section configured to abut an abluminal wall surface of the aorta, and an assembly including the tubular graft member and connection ring, for delivering the end-to-side connection.

Abstract: Connectors for fluidly coupling a tubular conduit to an anatomical structure. The connectors and their variants are each characterized by having at least one mechanically active tine that are actuated by extension or compression of a mechanical mechanism linking the active tines to a frame. The mechanical mechanism may actuate by one or more of shape memory, superelastic, elastic deformation, plastic deformation, electromechanical and/or other motive mechanism operably associated with the at least one mechanically active tines and the frame to rotate the tines about a hinge region under the influence of the mechanical mechanism.

Abstract: Connectors for end-to-end and/or end-to-side coupling of either anatomical tissue to other anatomical tissue and/or non-anatomical devices to anatomical tissue. The connectors and their variants are each characterized by having at least one mechanically active tine that are actuated by extension or compression of a mechanical mechanism linking the active tines to a frame. The mechanical mechanism may actuate by one or more of shape memory, superelastic, elastic deformation, plastic deformation, electromechanical and/or other motive mechanism operably associated with the at least one mechanically active tines and the frame to rotate the tines about a hinge region under the influence of the mechanical mechanism.

Abstract: Connectors for coupling a medical device access portion to an anatomical structure. The connectors and their variants are each characterized by having at least one mechanically active tine that is actuated by extension or compression of an actuating mechanism linking the active tines to a frame. The actuating mechanism may actuate by one or more of shape memory, superelastic, elastic deformation, plastic deformation, electromechanical and/or other motive mechanism operably associated with the at least one mechanically active tines and the frame to rotate the tines about a hinge region under the influence of the relative movement of the frame and the actuating mechanism.

Abstract: A device, assembly and method for end-to-side connection to anatomical tissue is disclosed. The device includes a tissue connection stent having a proximal closure to create and maintain a substantial degree of hemostasis. The assembly and method include using a tubular graft member coupled to a plurality of distally projecting tines extending from a distal aspect of the graft that couples the graft to an abluminal wall surface of an anatomic passageway, and the tissue connection stent is then introduced through a central lumen of the graft member, into and through an opening created in the wall of the anatomic passageway, and the tissue connection stent is deployed within the opening and a distal flange of the stent is seated against a luminal wall of the anatomic passageway while the proximal closure is maintained in a closed position until it is deployed to allow fluid flow through the stent.

Abstract: Methods for creating medical device access across walls of anatomical structures by providing connectors and a medical device access conduit coupled to the connectors The connectors and their variants are each characterized by having at least one mechanically active tine that are actuated by extension or compression of a mechanical mechanism linking the active tines to a frame.

Abstract: A vascular access device and assembly characterized by a tubular access graft having at least one angled distal flange that forms a non-circular distal opening to the tubular access graft, with the angled distal flange having a reinforcement structure that expands the flange and abuts a luminal wall surface of a blood vessel. Optionally, an axial compression ring or cuff may be provided that concentrically engages the tubular access graft and is translatable into a position that abuts an abluminal wall surface of the blood vessel. Also optionally, the device and assembly may include an annular ring with a plurality of axially projecting tines arrayed about a circumference of the annular ring, the annular ring being adapted to evert upon engagement with vascular tissue and creation of an access open by either an arteriotomy or a venotomy. The plurality of tines are configured to engage vascular tissue and then rotate to a different axial orientation to evert the periphery of the access site.

Abstract: A monolithic tissue screw fabricated of a single, unitary piece of material. The monolithic tissue screw has a helical coil portion and screw head portion with a driver aperture passing axially through the screw head portion and a co-axial with the helical coil portion such that a rotational torsional force applied by a mating driver to the driver aperture causes the helical coil portion to rotate about its axis. The helical coil portion engages tissue and draws the helical coil and the screw head portion into the tissue substantially only with the application of the rotational torsional force and substantially without an axial force applied to the tissue screw.
