Abstract: An insertion device includes an elongate member and a stylet. The elongate member has a proximal end portion, a distal end portion, and defines a lumen therethrough. The stylet has a distal end portion, a proximal end portion, and is slidably coupled to the elongate member. The stylet is configured to move from a first position to a second position with respect to the elongate member. The distal end portion of the stylet is configured to removably couple a mesh carrier thereto. A portion of the distal end portion of the stylet is disposed outside of the lumen of the elongate member when the stylet is in its first position and is disposed within the lumen when the stylet is in its second position.

Abstract: A scope device includes a shaft, a deflectable portion, and a handle portion. The shaft is inserted through a body lumen to a target area within a body. The shaft defines first and second lumens extending along a proximal portion thereof. The first and second lumens are merged to form a common lumen along a distal portion thereof via a fitting having a structure which, when connected to the first and second lumens, converge the first and second lumens toward the common lumen. The deflectable portion is connected to the distal end of the shaft and includes a channel aligned with and in communication with the common lumen. The handle portion includes a connector having a first hub including a first channel open to and in communication with the first lumen and a second hub including a second channel open to and in communication with the second lumen.

Abstract: A medical system may include an insertion device having a handle, a shaft coupled to the handle of the insertion device, and a port positioned on the handle of the insertion device. The port may be in fluid communication with a working channel of the shaft. The port may be a female luer port. The medical system may further include a medical device having a control member terminating in an end effector, a handle having a plurality of circumferential slots along the length of the handle, and a plunger moveable along a longitudinal axis of the handle of the medical device between a first position and a second position. In the first position, the end effector may be positioned within the shaft, and in the second position, the end effector may be positioned distally of the shaft.

Abstract: A ureteroscope system includes a handle; an elongated shaft extends from the handle to a distal end and includes a working channel which is opened at the distal end; an external member extends from a proximal end to a distal end and is coupled to the shaft, the member includes a hub and a tube defining a first external channel; and a coupling mechanism defines first and second tubes and is coupled the distal end of the member to the distal end of the shaft. The first tube defines a first lumen and the second tube defines a second lumen which is sized and shaped to receive a distal end of the member. A proximal portion of the first tube is sized and shaped to be inserted into a distal portion of the shaft such that the first lumen is opened to the working channel.
