Abstract:
1. A method of forming a submucosal bleb comprising the steps of: inserting a safe access needle injection instrument through a natural orifice in a patient, the safe access needle injection instrument including, positioning said safe access needle injection instrument adjacent a target site in the digestive tract; operating said safe access needle injection instrument to engage tissue at said target site, said operating including rotating the coiled configuration of the tissue holding member into the tissue such that coils of the coiled configuration extend within the tissue; elevating a mucosal layer by injecting a fluid into a submucosal layer at said target site to form a bleb using said safe access needle injection instrument; applying a cautery energy to the tissue holding member in the coiled configuration to cauterize a hole of the diameter of the coiled configuration in the tissue at said target site, wherein the cauterization of the hole releases engagement of the tissue holding member from the tissue; and removing said safe access needle injection instrument from said patient.
