  • E-mail

The FDA has the authority to require sponsors to perform a post-approval study (or studies) at the time of approval of a premarket approval (PMA), humanitarian device exemption (HDE), or product development protocol (PDP) application. Post-approval studies can provide patients, health care professionals, the device industry, the FDA and other stakeholders information on the continued safety and effectiveness (or continued probable benefit, in the case of an HDE) of approved medical devices. This database allows you to search Post-Approval Study information by applicant or device information.

Detailed Study Protocol Parameters
Study Design Description Study Objective and Design Objective: continued evaluation of safety and probable benefit post-approval of the Flourish device.

Design: a prospective, single-arm, observational clinical study. It is a new enrollment study.
Study Population Description A patient is suitable for participation in the study if the patient meets the following criteria:
1. Has esophageal atresia (EA)
2. Atretic gap < 4cm
3. Absence of, or repaired tracheoesophageal fistula (TEF)
4. Less than 1 year of age
5. Absence of visible teeth
6. Gastrostomy tract properly sized to accommodate an 18 Fr gastric catheter
7. Absence of gastrostomy site signs of significant infection (significant as determined by physician)
8. Parent or guardian of patient provides informed consent for use of data
No comparator group.
Sample Size A minimum of 20 patients will be enrolled
Data Collection The primary outcome measures for continued evaluation of device safety are the rates of the following:
- Stricture at the anastomotic site leading to the need for dilation or surgery
- Peri-anastomotic leaks
- Other adverse events and/or complications possibly, probably, or causally related to the device or procedure

The secondary outcome measure for evaluation of probable benefit is successful anastomosis formation. This is defined as creation of a lumen connecting the upper esophageal pouch to the lower esophageal pouch. Per the IFU successful anastomosis formation is confirmed by showing connected flow of contrast agent.
Follow-up Visits and Length of Follow-up 2 years
