Abstract:
1. A method for creating and accessing an anatomic space within a body and between an inner tissue and an outer tissue that are in close proximity to each other comprising the steps of: applying a distal end of a catheter against the outer tissue, the catheter comprising a catheter wall extending between a catheter proximal end and a cryoadhesion member, the catheter wall supporting the cryoadhesion member at the distal end of the catheter, and surrounding a catheter delivery lumen extending between a catheter delivery lumen proximal end opening and a cryoadhesion member distal end opening, the catheter wall surrounding a coolant lumen for circulating coolant to the cryoadhesion member, the coolant lumen extending between the catheter proximal end and the cryoadhesion member, the coolant lumen fluidly coupled to the cryadhesion member; cryoadhering an outer surface of the cryoadhesion member to the outer tissue by contacting the outer tissue with the cryoadhesion member, and manipulating the catheter distal end to tent the outer tissue to create the anatomic space between the inner tissue and the outer tissue; introducing a first instrument through the catheter delivery lumen proximal end opening; advancing the first instrument through the catheter delivery lumen to the cryoadhesion member distal end opening and to the outer tissue; and penetrating the outer tissue with the first instrument to access the anatomic space while the refrigerated cryoadhesion member stabilizes the outer tissue.
