Rectal anaesthesia delivery device and method

Abstract

Abstract A nerve stimulating trocar assembly (500) for insertion into tissue of a patient is disclosed, the nerve stimulating trocar assembly including an elongate trocar body (510) and a nerve stimulator (550). The trocar body (510) extends from a proximal end (511) to a distal end (512) and has an elongate open channel (520), which extends along a length of the trocar body (510). The nerve stimulator (550) has a shaft (560) extending from a proximal end (561)to a distal end (562), and at least one electrode (570) at or adjacent to the distal end (562) of the shaft (560). The open channel (520) of the trocar body (510) is configured to receive both a catheter tube and the shaft (560) of the nerve stimulator (550) such that the catheter is releasably secured between the trocar body (510) and the nerve stimulator (550) in an assembled configuration. Also disclosed are trocar assemblies and a method for positioning a catheter in a target tissue site. Abstract 20 26 20 61 47 16 J ul 2 02 6 A b s t r a c t 1 6 J u l 2 0 2 6 2 0 2 6 2 0 6 1 4 7
