Transabdominal Gastric Device and Method

An insertable trans abdominal gastric surgical system comprising:

• an introducer having a receiving passage and an outer tapered surface;
• a cannula having:
• an outer end removably connected to said introducer receiving passage;
• an inner end;
• a central portion having an outer-facing surface that extends between said outer end and said inner end and an inner-facing surface that defines a lumen configured to receive a portion of a medical instrument that traverses between said outer end and said inner end;
• an internal anchor connected to said inner end and having a surface shape configured to secure the system against an interior surface of an organ wall or peritoneal surface;
• wherein said introducer, cannula and internal anchor are configured for insertion into a patient by retrograde introduction past a patient's oropharynx and along an esophagus.

A method of inserting a surgical system in a patient, the method comprising the steps of:

• inserting a guidewire through a patient wall incision and into a patient organ or peritoneal space;
• guiding a portion of said inserted guidewire through an esophagus and mouth to provide an accessible portion of said guidewire;
• connecting a capture element of an introducer trans-abdominal gastric surgical system assembly to said accessible portion of said guidewire;
• pulling the guidewire connected to the capture element of the introducer surgical assembly in a direction away from the patient so the assembly is introduced into the patient organ or peritoneal space;
• continuing to pull the guidewire out through said wall incision to advance the introducer portion of said assembly out of the patient through said wall incision so that an internal anchor of said trans-abdominal gastric surgical system contacts an inner-facing organ wall or peritoneal surface of the patient;
• removing said introducer from said assembly to reveal an exposed end of said surgical system;
• connecting an external anchor to said exposed end of said surgical system;
• and
• moving said external anchor in a direction toward a skin surface of the patient to contact the skin surface in a position that faces said internal anchor to reliably secure said surgical system to the patient;
• thereby inserting said surgical system.
