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: 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: 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 translation: 公开了止血阀组件。 该组件包括具有径向向内朝向壳体远端逐渐变细的侧壁的壳体。 具有敞开的近端和形成有孔的锥形远端的阀构件设置在容纳室内。 阀构件在其中孔口基本上封闭的关闭构造和孔口打开的打开构造之间是可变形的。 设置在阀构件附近的偏置构件可在纵向压缩状态和纵向膨胀状态之间移动。 当处于膨胀状态时，偏置构件纵向推动阀构件并抵靠壳体的锥形侧壁。 壳体的锥形侧壁径向向内推动阀构件的远端，从而将孔推动到基本上封闭的构型。

Abstract: The present invention relates to methods of making a prosthesis or a stent with a smooth covering. The method includes providing an elastomeric tube including an inner diameter and an outer diameter, positioning the elastomeric tube in a tube expander including a vacuum, expanding the inner diameter and the outer diameters of the elastomeric tube by applying the vacuum, providing a mandrel, positioning an inner covering over the mandrel, positioning a stent over the inner covering, positioning an outer covering over the stent to form a covered stent, positioning the mandrel and the covered stent in the tube expander, releasing the vacuum, removing the elastomeric tube, the covered stent, and the mandrel form the tube expander, applying pressure and heat to the elastomeric tube, the covered stent, and the mandrel, removing the elastomeric tube, the covered stent, and the mandrel from the pressure and the heat, removing the elastomeric tube from the covered stent, and removing the mandrel from the covered stent.
