Sphincterotomes and methods for using sphincterotomes

Sphincterotomes and methods for making and using sphincterotomes are disclosed. An example sphincterotome may include an elongate shaft having an outer surface and a distal end region. The sphincterotome may also include a sphincterotome wire assembly having a distal end coupled to the distal end region of the elongate shaft and a body portion extending along the outer surface of the elongate shaft. The sphincterotome wire assembly may be designed to shift the distal end region of the elongate shaft between a first configuration and a curved configuration. The body portion of the sphincterotome wire assembly may include a cutting region and a non-conductive region.

Free standing bag with integrated cutting guard interface

A kit for extracting a tissue specimen includes a specimen container having a proximal rim and a specimen bag operably supported about the proximal rim and depending therefrom. The specimen bag includes a plurality of ribs depending from the proximal rim having a series of mechanical interfaces associated therewith and extending therealong. The kit also includes a cutting guard having a body with proximal and distal ends. The distal end is configured for insertion within the specimen bag when disposed within an incision and the proximal end defines an opening therein configured to facilitate introduction of one or more surgical instruments therethrough. The cutting guard includes one or mechanical interfaces operably associated with the body of the cutting guard configured to selectively engage one of the series of mechanical interfaces of one of the plurality of ribs of the specimen container upon insertion of the cutting guard within the incision.

Plasma surgery device

An electrosurgical wand is provided and includes a handle and an elongate shaft coupled to the handle and extending distally from the handle along an axis. An active electrode is disposed at a distal end of the electrosurgical wand. A return electrode abuts the elongate shaft and extends along and annularly about the axis. The return electrode has a top side adjacent the active electrode and an opposite bottom side and defines a notch. A support member is disposed in the notch between the electrodes and transitions curvilinearly from the notch to define a front surface extending laterally across and axially from the return electrode. The front surface tapers downwardly from the active electrode to define a first portion defining a first convex outer surface and also extends toward the bottom side of the return electrode to define a second portion defining a second convex outer surface.

An arthroscopic system includes a hand piece with a motor drive. an elongate shaft assembly is detachably secured to a distal end of the hand piece, and the elongate shaft assembly includes an outer sleeve and an inner sleeve rotatably mounted in the outer sleeve. The inner sleeve couples to the motor drive when the elongate shaft assembly is attached to the hand piece, and an inner distal cutting window on the inner sleeve moves in and out of alignment with an outer distal cutting window on the outer sleeve as the motor drive rotates the inner sleeve. A distal electrode is disposed on an outer surface of the outer sleeve at a location opposite to that of the outer distal cutting window, and the outer sleeve member is rotatable relative to the hand piece when the hub is secured to the hand piece such that a user can hold the hand piece in one hand and rotate the outer sleeve to selectively place the outer distal cutting window or the distal electrode in an upward orientation relative to the user while continuing to hold the hand piece in the one hand.
