Study: NCT05512052

Intervention type: DEVICE
Group type: EXPERIMENTAL
Intervention: Hannah Cervical Cup (2 mm Delta)
Description: The Hannah Cervical Cup reverses and prevents early cervical change by improving cervical collagen function. It applies negative pressure to the cervix, placing it in a tensile strain. Collagen under tension elicits fibers to realign, creating initial stiffness. This enables the cervix to remain closed. Over time, the extracellular matrix becomes strengthened as tension increases collagen strength and synthesis, and decreases degradation and adhesions. It also decreases prostaglandins--inflammatory mediators that facilitate birth. The Hannah Cervical Cup will create stiffness and length in the cervix, provide a treatment for early rupture of fetal membranes, and will offer a mode of medication administration. It is simple in nature, non-invasive, may be used in low-income, low-resource settings, can be placed by a physician in inpatient and outpatient settings, and does not require anesthesia during placement. The Hannah Cervical Cup (2 mm Delta) displaces the cervical tissue by 2 mm.
