Patent ID: 8721597

Claim:
An access device for creating a temporary cavity between organs in a body, the access device comprising: an elongate member having a working channel extending therethrough, the elongate member having a distal portion adapted for insertion into the body and a proximal portion, the elongate member being rigid and a column strength to allow insertion of the distal portion between organs; a slot shaped opening at a distal end of the elongate member, where a portion of the slot shaped opening extends along a side of the elongate member such that the slot shaped opening increases access to organs at the distal end and side of the elongate member, where the working channel exits the elongate member at the slot shaped opening; a rail-member having a far section, a near section, and a mid section located therebetween, where the far section can be affixed to a portion of the elongate member, the near section being moveable relative to the elongate member, such that distal movement of the near section causes the mid-section of the rail-member to assume an arcuate profile distally to the opening to position the rail-member in a shape to allow independent advancement of separate device over the rail-member.
