Ages Eligible for Study:   18 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:a.

  • Able to comprehend and sign or, if illiterate, leave their thumb impression on the study informed consent document
  • 18 years to 75 years (inclusive)
  • Admitted on an emergency or elective basis requiring a single gastrointestinal anastomosis
  • Willing to adhere to standard postoperative care, including ventilator support if required
  • Female subject is postmenopausal (for at least 2 years) or surgically incapable of child bearing (at least 3 months post-surgical sterilization, with appropriate documentation)
  • If female subject is capable of child bearing, must use an acceptable method of birth control (hormonal or IUD) for at least 3 months prior to surgery and continue use throughout the study; maintained normal menstrual pattern for the past three months and has a negative urine pregnancy test prior to day of surgical procedure
  • Absence of medical history of psychiatric disorders that could limit the subject's ability to understand the procedure, comply with medical, surgical, and/or behavioral recommendations.

Exclusion Criteria:

  • Women of childbearing potential who are pregnant at the time of screening or at the time of surgery
  • Subject is on treatment with Corticosteroid maintenance therapy (equivalent to > 10mg/day of Prednisone), immunosuppressive or chemotherapeutic agents within 14 days prior to enrollment; or likely to receive one of these drugs during study period
  • Subject has connective tissue disease, renal failure necessitating chronic hemodialysis or chronic ambulatory peritoneal dialysis as evidenced by serum creatinine of > 3mg/dL
  • Subject has liver failure as evidenced by CP category C
  • Immunocompromised subjects (hematological malignancies, history of bone marrow transplantation, splenectomized subjects, genetic disorders such as Lupus, severe combined immunodeficiency, etc.) or a positive HIV test result
  • Subject has extensive disseminated malignancy and unlikely to survive for more than 3 months based on investigator judgment
  • Any subject that the investigator determines is not likely to be compliant during the study period
  • Subjects determined or suspected to engage in substance abuse, or any subject who is currently, or has in the past 6 months, undergone substance abuse therapy
  • The investigator feels that the primary anastomosis is not feasible due to local conditions of the bowel or subject has unstable hemodynamic status requiring stoma
  • Participation in any other investigational device or drug study (non survey based trial) within 30 days of enrollment.
