Abstract: In some aspects, a sheath device includes a sheath shaft defining a lumen. The sheath shaft is configured to be inserted into the body of a patient. The sheath device includes a valve assembly coupled to a proximal end portion of the sheath shaft. The valve assembly includes a connector and an elastic member. The elastic member is coupled to the connector. The connector includes an arm portion that extends from a sidewall of the connector. The elastic member is configured to operate as a valve. The elastic member defines a lumen.

Abstract: Described are methods, systems, and techniques for a laser system controller, such as a controller for a laser used in a medical device. The controller can be configured to generate a pulse-width modulated control signal, the pulse-width modulated control signal comprising a plurality of electrical pulses separated by a temporal delay; and communicating the pulse width modulated control signal to an optical pump, wherein the optical pump, responsive to the pulse width modulated control signal, generates optical pump light and wherein a lasing medium, when exposed to the optical pump light, generates a laser beam.

Abstract: In one aspect of the present disclosure, a laser fiber may include an optical fiber. The optical fiber may include a proximal portion. The optical fiber also may include a distal portion having a distal end. The optical fiber may be configured to transmit laser energy from the proximal portion to the distal portion for emission of the laser energy from the distal end. The optical fiber also may include a distal tip surrounding the distal portion to protect the distal portion. The distal tip may include a sheet glass material having a laser energy emitting surface. The laser energy emitting surface may be defined by a chemically-strengthened surface layer.
