    Abstract: A catheter device for renal denervation ablation includes a flexible catheter shaft having an electrically insulating expandable member in its distal portion with at least one electrode located proximal to the member, at least one electrode located distal to the member, and with openings in the distal shaft with at least one opening proximal to the proximal electrode and one opening distal to the distal electrode of said electrode pair, said openings connected through an inner lumen in the catheter that provides a path for blood to flow through the expandable member. In one embodiment, the device comprises a flexible catheter shaft with a multiplicity of recessed paired electrodes disposed in recessed spaces in its distal portion, such that an electrically conducting portion of each electrode is exposed to the exterior of the catheter within a recessed space, and with an electrical insulator separating the electrodes of each pair.

    Abstract: Medical devices and methods of using medical devices are disclosed. An example tissue engagement device includes a first actuation member including a body coupled to a first jaw and a second jaw at a pivot point, wherein the body is designed to shift between a first configuration and a first compressed configuration and a second actuation member coupled to the first actuation member at the pivot point and at a fixation point, wherein the second actuation member is designed to shift between a second configuration and a second compressed configuration. Further, shifting the first actuation member from the first configuration to the first compressed configuration, shifting the second actuation member from the second configuration to the second compressed configuration, or both, shifts the first jaw and the second jaw between a closed configuration and an open configuration.

    Abstract: A clipping system includes an adapter, a clip and an extending member. The adapter mounted over an insertion device. The clip mounted over the adapter and includes first and second jaws connected to one another such that the jaws are movable between an insertion configuration and an initial deployed configuration. The first jaw includes a keyhole opening. The member coupled to the clip and adapter. The member includes a distal end releasably engaging the opening. The distal end has a width smaller than a width of a first portion of the opening and larger than a second portion of the opening so that, when a portion of the member proximal of the distal end is received within the second portion, the adapter is released from the clip while the member remains coupled to the clip. The member forces the clip open as the clip retracts over the adapter.

    Abstract: A retrieval device may have a contracted state and an expanded state. The retrieval device may include a sheath and at least three support members. Each of the support members may have a first portion with a first cross-sectional shape and a second portion with a second cross-sectional shape different from the first cross-sectional shape. A proximal end fixed of each of the support members may be coupled to the sheath, and a distal end may be movable relative to the sheath. The retrieval device may further include at least three movable members movable relative to the support members. Each movable member may extend through a lumen of one support member of the at least three support members and through a lumen of a different support member of the at least three support members.

    Abstract: An articulation joint includes proximal links, distal links, and intermediate links connecting the proximal and distal links. The articulation joint has a straight configuration along a straight longitudinal axis, a first bent configuration when the articulation joint bends toward a first side of the longitudinal axis, and a second bent configuration when the articulation joint bends toward a second side of the longitudinal axis, opposite to the first side. When the articulation joint is in the straight configuration, a first gap is defined at the first side between adjacent proximal links, and the adjacent proximal links contact each other at the second side, a second gap is defined at each of the first side and the second side between adjacent distal links, and a third gap is defined at the first side between adjacent intermediate links, and adjacent intermediate links contact each other at the second side.
