摘要:
Described herein are devices and methods for positioning a wire around a target tissue. In some embodiments, a probe device includes a rigid outer cannula having a curved distal region and a flexible inner cannula slideably disposed within the rigid outer cannula, wherein the inner cannula is configured to assume a curved shape when extended distally from the outer cannula. In some embodiments, the probe device further includes a distal tip at the distal end of the inner cannula and a safety retainer cable coupled to the distal tip and secured to the probe proximally from the distal end of the safety retainer wherein the safety retainer cable extends proximally from the distal tip and is slack. In some embodiments, the inner cannula comprises an elongate body with a longitudinally extending support member and a longitudinally extending tubular body, configured to pass a wire, disposed inside the elongate body.
