Abstract: The disclosure relates to medical devices and methods of assembling medical devices, such as MRI-compatible interventional wireguides. An example of a wireguide includes a series of individual segments, a plurality of connectors, and a plurality of spacers. Each segment in the series of individual segments has a first end and a second end. Each connector of the plurality of connectors joins adjacent segments in the series of individual segments to one another such that a first end of a first segment and a second end of a second segment in the series of individual segments are attached to a connector of the plurality of connectors. A spacer of the plurality of spacers is disposed between each pair of adjacent segments in the series of individual segments. Each of the segments in the series of individual segments is electrically insulated from an adjacent segment in the series of individual segments.

Abstract: The present embodiments provide systems and methods for treating a medical condition. In one embodiment, the system comprises a stent having proximal and distal regions, and further having a delivery state and an expanded state. A therapeutic agent is disposed on a segment of the stent. The stent is disposed around an exterior surface of a core assembly in the delivery state. A coupling assembly releasably secures the proximal region of the stent to the exterior surface of the core assembly. The coupling assembly secures the stent to the core assembly for a predetermined period while the stent is in the expanded state and during release of the therapeutic agent at a target site. The coupling assembly further enables the stent to be disengaged from the core assembly and deployed in a bodily passageway.

Abstract: Disclosed herein is a hybrid stent having a balloon-expandable portion joined to a self-expanding portion. The hybrid stent is capable of withstanding the forces applied by delivery. Delivery systems for deploying a hybrid stent are described, as are methods of using such delivery systems.

Abstract: Disclosed herein is an assembly including a balloon catheter as an inner catheter for the delivery of a self-expanding stent. The delivery assembly may lack a separate pusher structure. A method of using a single assembly to delivery a self-expanding stent and provide a post-dilatation step is also described herein.

Abstract: A hemostatic valve assembly is disclosed. The assembly comprises a housing having a sidewall that tapers radially inwardly towards the housing distal end. A valve member having an open proximal end and a tapered distal end with an orifice formed therein is disposed within the housing chamber. The valve member is deformable between a closed configuration in which the orifice is substantially closed and an open configuration in which the orifice is open. A biasing member disposed proximal to the valve member is moveable between a longitudinally compressed condition and a longitudinally expanded condition. When in an expanded condition, the biasing member pushes the valve member longitudinally and against the tapered sidewall of the housing. The tapered sidewall of the housing urges the distal end of the valve member radially inwardly, thus urging the orifice to the substantially closed configuration.

Abstract: A device for insertion into a vessel and suitable for implementing translational movement through the vessel includes a flexible tube containing a translational actuator. Anchoring actuators are positioned along the length of the flexible tube and are configured to controllably expand against the inner wall of the vessel in coordination with extension and contraction of the translational actuator to effect translational movement.
