A method for performing a medical procedure may comprise advancing a first device through a first body lumen. A distal portion of the first device may include a magnet. The method may further comprise advancing a second device through a second body lumen. The second device may include a magnetic field sensor. The method may further comprise receiving a signal from the magnetic field sensor. The signal may be indicative of a magnetic field measured by the magnetic field sensor. The method may further comprise, if the received signal matches a magnetic field of the magnet, identifying a position of the magnet.

Devices and methods for treatment of body lumens

According to one aspect, a medical device may be configured for use with an endoscope and may include a tool. The tool may include an actuator, at least one extension at a distal portion of the actuator, and a distal end. The at least one extension may extend radially outward from the actuator and may have an edge configured to fragment debris within a body. The medical device may also include a cap configured for coupling to a distal end of the endoscope, and the cap may include a body defining an opening and a cavity. The opening may be configured to align with optics of the endoscope, and the at least one extension may be positioned within the cavity of the body.

Medical devices and related methods

A steering system for a medical device may include a first drive member having a central longitudinal axis; a central shaft extending through the first drive member; a control knob coupled to the first drive member; a braking knob coupled to the central shaft and including a first protrusion; and a brake shoe member coupled to the central shaft between the control knob and the braking knob. The first protrusion may be positioned within a first channel of the brake shoe member; the first protrusion may be configured to engage the brake shoe member to move a first arm of the brake shoe member radially outward towards a wall of the control knob when the braking knob is rotated in a first direction; and the first arm may be configured to move away from the wall when the braking knob is rotated in a second direction.

Braking mechanisms for steerable medical devices and related methods

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.

Sphincterotomes and methods for using sphincterotomes

A medical device may comprise a sheath configured to be inserted into a body lumen of a patient. A distal end of the sheath may include an elevator for changing an orientation of a medical device. A handle may include an actuator. The actuator may be operably connected to the elevator. Activation of the actuator may cause movement of the elevator. An engaging portion may, in at least one configuration of the handle, protrude from a surface of a handle body toward the actuator. A force exerted by the user on at least one of the actuator or the engaging portion may cause the handle to transition between (a) a first configuration in which the engaging portion interacts with the actuator to inhibit movement of the actuator relative to the engaging portion and (b) a second configuration in which the actuator is movable relative to the engaging portion.

Locking mechanisms for endoscopic devices

Medical devices and related methods are described. The medical device may include a shaft, a handle housing a proximal portion of the shaft, and a lock having a first configuration and a second configuration. In the first configuration of the lock, the shaft may be rotatable about a longitudinal axis of the shaft relative to the handle, and, in the second configuration of the lock, the shaft may be stationary relative to the handle.

Rotatable medical device

A method for performing a medical procedure may comprise advancing a first device through a first body lumen. A distal portion of the first device may include a magnet. The method may further comprise advancing a second device through a second body lumen. The second device may include a magnetic field sensor. The method may further comprise_receiving a signal from the magnetic field sensor. The signal may be indicative of a magnetic field measured by the magnetic field sensor. The method may further comprise, if the received signal matches a magnetic field of the magnet, identifying a position of the magnet.

The present disclosure relates to medical devices that that include the following: a flexible elongate tube having a proximal end and a distal end configured to be directed toward an opening of a body lumen; a first lumen extending from the distal end of the tube proximally along the tube and having a fluid connection for a fluid source at its proximal end; a second lumen extending from the distal end of the tube proximally along the tube, the second lumen configured to accept a guidewire extending along the second lumen; and a wire filament extending along the elongate tube, a distal end of the filament connected to the distal end of the elongate tube, a proximal portion of the wire extending at least partially along the elongate tube, and a distal portion of the wire extending external to the elongate tube.
