Gastric obstruction device deployment assembly and methods of delivering and deploying a gastric obstruction device

A method of delivering and deploying an intermittently obstructive gastric obstruction device, comprising:

• advancing a delivery tube distal end per-orally into proximity of a stomach of a patient;
• advancing a control tube slidably positioned through the delivery tube such that a distal portion of the gastric obstruction device is released from the delivery tube;
• maintaining a position of the control tube relative to the delivery tube distal end such that the gastric obstruction device is advanced distally of the delivery tube distal end and nests into a compacted configuration whereby the gastric obstruction device is formed from its distal end and towards its proximal end into its deployed configuration;
• and
• tightening one or more lock lines passing through the gastric obstruction device in its compacted configuration until a corresponding tensioning wire pin is locked to maintain the compacted configuration.

A method of delivering and deploying an intermittently obstructive gastric obstruction device, comprising:

• advancing an access sheath per-orally into proximity of a patient stomach, wherein an obturator is coupled to the access sheath during introduction into the patient stomach;
• removing the obturator from the access sheath when a distal end of the access sheath is in the patient stomach, wherein the access sheath is coupled to the obturator;
• inflating an expandable member on the distal end of the access sheath in the patient stomach;
• and
• advancing the gastric obstruction device through the proximal end of the access sheath into the patient stomach at the distal end of the access sheath.
