    摘要： Provided herein is a medical device, including an instrument having a proximal end and a distal end, an introducer configured to moveably receive the instrument and having and outer housing having a proximal end, a distal end, and a sidewall therebetween defining an inner volume and an inner housing having a proximal end, a distal end, and a sidewall therebetween defining an inner volume, the inner housing slidably received within the outer housing, the distal end of the introducer configured to couple the introducer to an intravenous line. The inner housing is configured to move relative to the outer housing to move the instrument between a first position and a second position.

    摘要： A medical device 1 includes a main body driving unit (300) including a plurality of driving sources (M11 to M33), a base unit (200) including a coupling device (21) connected to the main body driving unit, a bendable unit (100) configured to be detachably attached to the base unit, and an operation unit (400) configured to be movable between a fixed position and a detachment position. The base unit includes a plurality of coupling units (21c11 to 21c33). The bendable unit includes a plurality of linear members (W11 to W33). A state where each of the plurality of linear members is fixed by each of the plurality of coupling units and a state where each of the plurality of linear members is unfixed from each of the plurality of coupling units are switched in an interlocked manner with movement of the operation unit.

    摘要： Systems and methods for positioning a wire for advancement through a vessel wall, and advancing it through one or more vessel walls, generally include a delivery catheter and an alignment catheter or a receiving catheter, and a guidewire. In some variations, the systems and methods may be used to bypass an occlusion or other barrier that may prevent advancement of a wire or tools through an endoluminal space. In these variations, the systems and methods include a delivery catheter, a bypass catheter, a receiving catheter, and a guidewire. The delivery and receiving catheters each generally include a side aperture, a deflection surface, and an alignment element, and the bypass catheter generally includes two side apertures, two deflectors, and two alignment elements. In some variations, the systems and methods may assist in treatment of a patient suffering from critical limb ischemia.
