ENDOSCOPIC NEEDLE STYLET WITH ENHANCED-FLEXIBILITY LENGTHS |
摘要 |
A single-wire stylet may be constructed as an elongate single-wire, memory-metal alloy body with a generally cylindrical body profile, extending distally from a proximal end terminus, where embodiments include a polymeric distal tip member fixedly attached directly at a distal end of the single-wire body. At least one lengthwise portion of the single- wire body is at least partially in martensitic phase at operating temperatures at and below about 37°C. Where present, the polymeric distal tip member has a generally cylindrical body profile circumferentially bounded by an outer circumference substantially equal to or greater than that of the metal body. The polymeric distal tip member may be overmolded upon a distal-end tip length of an elongate single-wire, memory-metal alloy stylet body, where the distal end and/or discrete intermediate distal-portion length(s) that include martensitic-phase alloy and any polymeric member have greater flexibility than a proximal-most length of the alloy stylet body. |
