Abstract: A surgical device (10) for injecting a chemical agent within a subject for use in endoscopic injection therapies is disclosed. The device (10) includes a support body (20), a motion transmitting unit (25), an agent delivery system (30) and a guide housing (40). The motion transmitting unit (25) is movable relative to the support body (20). The agent delivery system (30) includes a needle (31) for extending into a subject and structure defining a conduit between the support body and the needle (31). The guide housing (40) has a flexible elongated body, and internal elongated passage and friction reducing material lining the passage. At least a portion of the motion transmitting unit (25) adjacent the needle (31) is slideably housed within the guide housing (40). The device (10) offers a surgeon improved ease of needle extension and retraction when the distal end of the endoscope is bent at acute angles.
