JADA Uses Vacuum to Induce Physiologic Contraction of the Atonic Uterus

The majority of postpartum hemorrhage cases are caused by uterine atony.1

The JADA System with low-level vacuum connected

The uterus is composed of a web-like network of muscle fibers in its middle layer, called the myometrium. When the placenta separates from the uterine wall after childbirth, that portion of the myometrium is left with open blood vessels, resulting in bleeding. Typically, the uterus contracts and compression of those open vessels stops bleeding. In some instances, the uterine muscle fibers do not contract, causing uncontrolled bleeding, referred to as abnormal postpartum uterine bleeding or postpartum hemorrhage.

Uterine contraction with the JADA System

When connected to a low-level vacuum source (80 mm Hg +/- 10 mm Hg; not to exceed 90 mm Hg), JADA establishes a vacuum within the uterus, causing the uterus to contract and leading to control of the bleeding. In a clinical study (n=107), contraction of the uterus was observed in a median of 1 minute with control of bleeding observed in a median of 3 minutes.2

Innovation That Works

JADA is made of soft silicone and a survey found that it is easy to use (98%, n=105/107).

An Intrauterine Loop has interior Vacuum Pores inside a protective Shield to evacuate blood.

An expandable Cervical Seal is filled with sterile fluid to create a seal that holds a vacuum within the uterus.

A connector at the end of the tube is attached to a regulated vacuum source.

Before using JADA, please read the contraindications, warnings, precautions, and other important information in the accompanying Instructions for Use.
