The DiLumen Endolumenal Interventional Knife (“DiLumen Ik”) is a sterile, disposable monopolar electrosurgical device intended to be used for cutting, dissecting, and cauterizing tissue within the digestive tract during endoscopic procedures. The device is also indicated for the induction of sterile normal saline into the submucosa to lift mucosal lesions under direct endoscopic visualization. The DiLumen Ik utilizes a pistol style Handle, a Flexible Shaft with an articulating section at its distal end, and a stainless-steel Knife Tip that can be extended and retracted. The Handle incorporates controls that allow the clinician to rotate the Shaft, extend or retract the Knife Tip, articulate the distal end of the Shaft in a specific plane, and lock the articulation in a fixed position. There is also a female Luer Lock connector on the Handle that can be used with a standard luer lock syringe to introduce sterile saline at the distal end for flushing tissue debris from the knife tip or creating a bleb to lift mucosal lesions
A collection of devices designed to be used during an endoscopic mucosal resection procedure to: 1) lift a section of diseased mucosa by injection of a submucosal lifting solution; and 2) resect the lesion using monopolar electrosurgical energy; it may in addition include devices designed to perform vacuum elevation of the lesion to supplement submucosal lifting. It includes a submucosal injection needle, an electrosurgical electrode (e.g., polyp snare), and might include additional supportive devices such as a dye spray catheter and endoscope suction cap. This is a single-use device.
