* 24- hours Home Ambulatory Blood Pressure Monitor (ABPM), only for patients diagnosed with hypertension: Screening, 6 and 12 months

* Laboratory tests including: (1) Hematology blood tests, (2) Biochemistry blood tests for: sugar Metabolism, liver, proteins, and lipid (3) Urinalysis (Dipstick) tests: Screening, 6 and 12 months.

* Physical examination (include at minimum examination of: GI, Cardiopulmonary, Hepatobiliary and extremities systems) - Screening and procedure day.

* Vital signs (blood pressure and heart rate - supine, pulse, body temperature, respiratory rate (RR) and SpO2): Screening, procedure day, 1 week, 1, 2, 4, 6, 8, 10 and 12 months

* BMI and Waist circumference: Screening, procedure day, 1 week, 1, 2, 4, 6, 8, 10 and 12 months

* Meeting with dietitians / lifestyle modifications counseling: at all follow up office and remote visits:

* Office visit: Screening, procedure day, 1 week, 1, 2, 4, 6, 8, 10 and 12 months

* Remote follows up (phone calls) at months 3,5,7,9, and 11.

* IWQOL-Lite: Screening, 2, 6 and 12 months

* PHQ-9: Screening

* Pregnancy test (only for the relevant population): Procedure day

The patient will required to follow a specific diet and to have a physical activity during the study period ( 12 month).

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: SINGLE_GROUP

Arm && Interventions

Group	Intervention	Description
EndoZip System	EndoZip System	The Nitinotes EndoZip system is designed to allow for the creation of multiple internal gastric segmentation (up to 5) in the stomach by using an endoscopic approach. The system allows the forming of wall-to-wall longitudinal attachments of the anterior and posterior stomach walls, creating multiple strictures within. Creation of this segmentation may significantly reduce gastric volume, may affect gastric motility and consequently, reduce weight.

Primary Outcome Measures

Name	Time	Method
Percent of patients with a reduction in %TBWL of at least 10% at 12 months	12 months	Percentage of patients with a reduction in %TBWL of at least 10% at 12 months
Percent of total body weight loss (%TBWL) after 12 months.	12 months	percent of TBWL from baseline (prior to EndoZip procedure) and 12 month post EndoZip
safety evaluation- Rate of adverse events	12 months	The cumulative incidence of adverse events observed during the procedure and throughout the follow-up period, will be presented in tabular format. A detailed list of all adverse events will be presented. The adverse event rate will be compiled with respect to seriousness, severity, expectedness and relationship to procedure and device.
