Abstract: A delivery device for delivering a pacing lead to the His bundle of a patient's heart includes an elongated sheath having a distal end, and a plurality of mapping electrodes positioned at the distal end. The distal end of the sheath may have a distal tip, and the mapping electrodes may include two electrodes that diametrically oppose one another at a position spaced from the distal tip of the sheath. The sheath includes a plurality of flexible sections spaced apart from one another, and a pull wire that causes the sheath to deflect from a straight configuration to a dual hinged curved configuration that positions the electrodes in the vicinity of the bundle of His.

Abstract: An electro-anatomical model of the mammalian His/Purkinje system includes a shell simulating the anatomy of at least a portion of a mammalian heart. The shell has a hollow interior and a first port providing an aperture to the interior of the shell. A plug is inserted in the first port so that a surface of the plug is exposed to the interior of the shell. An electrical circuit provides signals to electrodes in the plug which simulate the electrical signals generated by the bundle of His/Purkinje system in vivo. A second port provides access to the interior of the shell for an introducer catheter to locate the simulated bundle of His and to insert a pacing lead therein. The model is useful for developing tools for His pacing and for training users in techniques for implanting His pacing leads.

Abstract: A tissue puncture closure assembly including a wire assembly and first and second devices. The wire assembly includes a first wire member and a second wire member that each include a distal end portion and a proximal end portion. At least portions of the second wire member are arranged side-by-side with the first wire member. The distal end portion of the first wire member is connected to the distal end portion of the second wire member, and a proximal end portion of the first wire member is disconnected from the proximal end portion of the second wire member. The first device is operable to advance over the first wire member. The second device is operable to advance over the second wire member.

Abstract: A tissue puncture locator device includes an anchor assembly and a sealing member. The anchor assembly includes an anchor portion, a tube portion, and a filling member. The anchor portion is positioned at a distal end of the tube portion and configured for placement through a vascular incision into a vessel. The anchor member has an unexpanded configuration that permits passage through the vascular incision and an expanded configuration that limits passage through the vascular incision. The filling member is retained in the tube portion and adapted for insertion from the tube portion into the anchor member to provide the expanded configuration, and adapted for retraction from the anchor member into the tube portion to provide the unexpanded configuration. The sealing member is configured for placement adjacent the vascular incision outside the vessel.

Abstract: A tissue puncture locator device includes a temporary anchor configured for placement through a vascular puncture into a vessel. The temporary anchor includes a column member that defines a lumen. The temporary anchor is movable between an uncompressed position and a compressed position, wherein in the compressed poition a portion of the column member protrudes radially outward. The column member may include a reduced thickness portion, wherein the column member protrudes radially outward at the reduced thickness portion. The column member, when expanded radially outward within the vessel, is sized to limit retraction of the temporary anchor through the vascular puncture.

Abstract: A slam latch mechanism employs an actuation lever rotatable from a first position to a second position and having a prong extending therefrom. A bolt, resiliently retractable from an extended position with the actuation lever in the first position, has a land with a slip surface engaging the prong in the second position to retract the bolt. A dampener extends from the slip surface by a margin to engage the prong in the first position to prevent metal to metal contact by the prong and slip surface with the actuation lever in the first position.

Abstract: A method and apparatus for associating an edge of a first object with a second object using an insert. In one illustrative embodiment, an apparatus comprises a structure and a number of attachment features associated with the structure. The structure is configured to be inserted within a hollow portion of the first object at an edge of the first object. The structure is further configured to span an entire thickness of the first object at the edge of the first object.
