MityOne - Vacuum-Assisted Delivery

MityOne Ensures Greater Control for Safer Vaginal and C-Section Deliveries

MityOne, the latest introduction to the Mityvac family of products, provides optimal safety for patients and superior control for clinicians.

Newly redesigned based on feedback from prominent obstetricians, this versatile, one-piece unit offers significant benefits for deliveries:

• Shorter stem for improved tactile feedback and intuitive handling
• Self-limiting pressure gauge will not exceed recommended suction levels of 58 cmHg
• Soft bell cup interface results in less trauma versus hard plastic cups
• Extremely high efficacy rate of up to 97% for the mushroom cup
• Prominent vacuum trigger release placed closer to operator to ensure ease of use
• Rotating, semi-rigid stem will not transfer torsion to baby
• Convenient tray packaging allows for easy stacking and storage

MityOne^® is Gentle, Effective and Easy to Use throughout the Arc of Delivery

MityOne’s semi-rigid, shorter stem offers improved tactile feedback for greater control. It helps minimize pop-offs by allowing physicians to accurately determine the relationship between the stem and the baby’s head when following the Arc of Delivery.

1. Choose the appropriate MityOne cup based on fetal presentation.

2. As station is gained, the axis should be positioned downward toward the patient’s rectum initially. Then, as the baby’s head crowns, the axis should be extended above the horizontal position.

3. Once the baby’s head is delivered, slowly release the vacuum using the release trigger and remove the cup.

4. Continue delivery in the usual manner.

Placing Precise Control in the Physician’s Hands

The MityOne® features a new shortened, semi-rigid stem that provides the physician with tactile feedback and significantly enhanced control during delivery. The stem is aligned for correct placement along the pelvic curve to follow the angle of traction as the infant’s head moves smoothly from mid-pelvis to outlet. The MityOne pump creates vacuum with minimal effort and no assistance required – and a prominent trigger release disengages vacuum as needed.

The Safer Approach to Vacuum-Assisted Delivery

Safety is integrated into all aspects of the MityOne from the pump to the cups. The self-limiting vacuum will not exceed the recommended suction level of 58 cmHg. And, a color-coded rotary gauge clearly visible on the handle makes it easier to manage vacuum levels between contractions. The freely rotating stem minimizes torsion-related injuries while maintaining needed control.

The MitySoft^® Bell Cup offers a safer patented interface that has been shown to lower the incidence of scalp trauma in infants by as much as 68%.1 In both the Cochrane Database of Systematic Reviews and UpToDate^®, soft bell-shaped vacuum extractors like the MitySoft were recommended for uncomplicated, occiputanterior (OA) deliveries.1, 2 Peer-reviewed studies show that hard plastic and steel cups used in vacuum-assisted deliveries can cause laceration rates of up to 14.1%.6

Highest Efficacy Rate Minimizes Laceration Rates and Pop-Offs

MityOne cups strike the perfect balance of safety and efficacy. The gentle but effective M-Style^® Mushroom^® Cup has a proven success rate of up to 97% with laceration rates averaging less than 1.59%.3, 4, 5

The semi-rigid MitySoft Bell Cup reduces the risk of pop-offs while providing pulling power approaching that of a mushroom cup. Both cups have an integrated filter that allows 360° air movement around the perimeter and center of the cup – enabling a secure, reliable and repeatable traction level.
