Abstract
In some implementations, a PDT delivery device is disclosed that may include a housing including a handle, a fiber lock orifice, a probe insertion orifice and a tube retraction groove positioned between the fiber lock orifice and the probe insertion orifice. In addition, the PDT delivery device may include an insertion probe having a stepped hollow cylinder positioned within the probe insertion orifice and within the tube retraction groove and having an insertion needle at a distal end. The PDT delivery device may include a fiber locking mechanism and a probe release mechanism selectively movable between an unlock position and a lock position. Also, the PDT delivery device may include a probe retraction mechanism releasably coupled to the insertion probe. Further, the PDT delivery device may include a retraction trigger coupled to the probe retraction mechanism to translate the insertion probe between an insertion position and a retraction position.
