Abstract: A medical system includes an insertion device including a handle and a delivery portion, a laser fiber, a conductive wire, and a lock. The laser fiber extends through the insertion device and is coupled to a laser slider to control a position of the laser fiber relative to a distal end of the delivery portion. The conductive wire extends through the insertion device and is coupled to a wire slider to control a position of the laser fiber relative to a distal end of the delivery portion. The lock is positioned within the handle and is movable in order to selectively lock either the movement of the laser slider or lock the movement of the wire slider.

Abstract: Devices for guiding an instrument into a body of a patient, at a targeted point of entry and along an insertion path at a targeted insertion angle, are described herein, such as a guide for an access needle in a PCNL procedure for accessing the kidney to remove kidney stones. The devices include base component aligned with a point of entry, and a guide assembly which cooperates with the base component to allow an instrument to be aligned and fixed at various circumferential and vertical angles. The devices and methods allow a medical professional to accurately and stably guide an instrument at a targeted point and angle and to a desired depth, while minimizing the exposure to radiation used to image the insertion path.

The base component is aligned in use with the point of entry and the guide assembly cooperates with the base component to allow for the instrument to be aligned and fixed at any circumferential angle around an axis perpendicular to the point of entry and at any vertical angle ranging from 0 to 45 degrees away from the axis in a direction toward the body. The optional mechanism allows for mechanical insertion once the instrument is aligned and fixed.

Abstract: A medical stent provides an active agent to a patient's body while simultaneously maintaining an open passageway within the body of the patient. The stent includes a first segment, a second segment, a connecting segment disposed between the first and second segments, and the active agent. The active agent may be a hemostatic agent that stops or controls bleeding by coagulation, or any other medical drug, such as, for example an antibiotic or an anticoagulant. When the stent is properly positioned within the patient's urinary system, the first segment is located on one side of the external sphincter and the second segment is located on the other side. The connecting segment is sized to extend through the external sphincter to couple the first and second segments together while not interfering with the normal operation of the external sphincter.
