Abstract: In an exemplary arrangement, a vapor generator for use in a medical device may include a heating core in fluid communication with a source of fluid and defining at least one fluid pathway along which fluid from the source of fluid travels. The at least one fluid pathway may include one or more surfaces that generate turbulence in the fluid. The vapor generator may also include a coil disposed about the heating core, wherein the coil is configured to receive a current so as to heat the fluid traveling along the at least one fluid pathway, thereby generating a vapor.

Abstract: A needle adjustment device is provided. The needle adjustment device includes a stopping component and an actuator. The stopping component is configured to establish a maximum penetration depth of a needle. The actuator is fixedly coupled to the needle and movable proximally and distally to one or more positions and to adjust a penetration depth of the needle depth up to the maximum penetration depth.

Abstract: A scope adapter system includes an adapter body coupled to a handle of a scope device, a rigid shaft, and a mounting mechanism removably coupled to the shaft. The shaft includes a shaft lumen which is sized and shaped to slidably receive a flexible elongated member of the device. A distal end of the lumen is sized so that, when a distal end of the member is received therein, the distal end of the member is snugly held so that an aim of the shaft aims the distal end of the member. The mechanism mounts a proximal end of the shaft to the body so that, when the body is coupled to the handle, the mechanism is mounted on the body and coupled to the shaft and the member is inserted into the lumen so that movement of the handle effects corresponding movements of the distal end of the member.

Abstract: Medical systems are described, including a medical system that includes a sheath with at least one lumen configured to be coupled to a suction source, an irrigation device that includes at least one irrigation lumen configured to be coupled to an irrigation source, and a medical device that includes a handle and a shaft. The shaft may include a working channel with a distal opening, one or more illumination devices, and one or more visualization devices. The medical device may be configured to be positioned within the sheath during delivery of the sheath to a treatment site and during an application of energy to break up one or more objects to form one or more particles or dust. The irrigation device may be configured to be positioned within the sheath and deliver irrigation fluid while suction is applied to the treatment site.
