1. A system for preventing inadvertent actuation of a medical device, the system comprising:
- a medical device comprising a laser and configured to transition between an actuated state and an inactive state;
an elongate tube having a proximal end, a distal end, and a lumen extending from the proximal end to the distal end, the lumen configured to receive the medical device; and
a detection system configured to determine a position of a distal end of the medical device relative to the distal end of the elongate tube, wherein the detection system includes a transmitting element disposed on a distal portion of the elongate tube and a receiving element disposed on a distal portion of the medical device.

Abstract
A system for preventing inadvertent actuation of a medical device. The system includes an elongate tube having a proximal end, a distal end, and a lumen extending from the proximal end to the distal end. The lumen is configured to receive a medical device configured to transition between an actuated state and an inactive state. The device further includes a detection system configured to determine a position of a distal end of the medical device relative to the distal end of the elongate tube. The detection system includes a transmitting element and a receiving element.

9. A system for determining the position of a medical device, the system comprising:
-
a medical device comprising a laser; an elongate tube having a proximal end, a distal end, and a lumen extending therebetween, wherein the lumen is defined by an internal wall of the elongate tube, the medical device is slidably positioned within the lumen, and the elongate tube includes an illumination element disposed between the internal wall and an external wall of the elongate tube; a geometric feature disposed at a first location of the internal wall, wherein the geometric feature is configured to deflect a portion of light energy from the illumination element to a sensor disposed on the medical device, wherein the medical device is configured to move between a first position and a second position, wherein, when in the first position, a distal end of the medical device is disposed proximally of the first location, and, when in the second position, the distal end of the medical device is disposed distally of the first location. - View Dependent Claims (10, 11, 12)

13. A method of determining a position of a laser medical device within a lumen of an endoscopic access device, the endoscopic access device including a light source, the method comprising:
-
sensing an intensity of light reflected from the light source; comparing the sensed intensity to a predetermined threshold intensity; and if the sensed intensity is below the predetermined threshold intensity, generating a first signal indicative of a first position of the medical device; wherein the step of sensing is accomplished by a sensor located on the laser medical device. - View Dependent Claims (14, 15)
