    摘要： A vascular prosthesis comprises generally tubular body placeable in contracted and expanded states and has an axial length and a circumferential dimension in the expanded state. The body includes a series of circumferential elements having first lengths. First and second connectors have connector lengths and join alternating ends of adjacent circumferential elements. The first length plus the connector lengths joined thereto equal a total circumferential length. Each connector length is between 2.5% and 25% of the total circumferential length. Adjacent circumferential elements and connectors extending therefrom are separated by a stress relief slot having a relief slot length of more than 50% and less than 95% of the total circumferential length. The stress relief slots have narrow width portions over a majority of the relief slot lengths, the narrow width portions having lateral dimensions of no greater than about 3 mm.

    摘要： A catheter assembly includes a catheter, including an inner member and a sheath, extending from a handle. The handle includes a housing, a braking assembly, a carriage and a carriage driver. The braking assembly comprises a braking element within the housing interior and a braking element rotator. The carriage comprises at least one carriage braking surface engaging the braking element. The carriage driver, such as a spring, biases the carriage towards the proximal end of the handle. The inner member has a proximal end secured to the housing. The sheath has a proximal end secured to the carriage. Rotating the braking element causes the carriage to move proximally as the carriage braking surface slides along the braking element. This causes the sheath to move proximally relative to the inner member.

    摘要： The vasoocclusive device for use in interventional therapy and vascular surgery adapted to be inserted into a portion of a vasculature, includes a vasoocclusive coil disposed about an inner reinforcement coil wherein said vasoocclusive coil is helically wound and the inner reinforcement coil forms a reverse helical winding opposite the vasoocclusive coil winding, thereby forming a biplex wound coil. The vasoocclusive device biplex winding provides improved mechanical properties to the device. An inner reinforcement stretch resistant member attached within the biplex windings limits coil stretchability.
