Abstract:
1. A method comprising: inverting a proximal end portion of a deformable member from a distal-facing orientation to a proximal-facing orientation to receive a distal end portion of a treatment device; coupling the treatment device and a dilator assembly comprising a tubular shaft and the deformable member, including advancing the distal end portion of the treatment device into the proximal end portion of the deformable member; sheathless introduction of the treatment device into a body vessel or body cavity, including inserting the treatment device coupled with the dilator assembly into the body vessel or body cavity; advancing the treatment device and the dilator assembly to a target location within the body vessel or body cavity; after reaching the target location within the body vessel or body cavity, decoupling the treatment device from the dilator assembly; and removing the dilator assembly from the treatment device, including fully retracting the tubular shaft and the deformable member through a lumen of the treatment device.
