The G-LIFT was designed and developed based on the well-established orthopedic principle of force transfer.
G-LIFT TOP BENEFITS: MOBILITY & NECK PROTECTION**
The G-LIFT transfers the weight of a lead apron from the back and shoulders to the wearer’s iliac crest. This weight transfer improves arm and neck mobility. More importantly, the neck is protected by the G-LIFT system from potentially dangerous posterior pressure from the weight of lead during head movement.
Multiple prototypes have been developed and field-tested on males and females with various body types. Each part of the G-LIFT has been meticulously designed and manufactured using only the highest quality material high-grade aircraft aluminum was chosen because of its lightweight and durability.
TOP LIGHT MATERIALS IN THE G-LIFT
Aluminum’s rigid form was felt to be very important to keep the weight of the lead off of the shoulders. The aluminum support bars were specifically designed to be positioned above the shoulders and also far enough forward to avoid weight on the upper chest wall to ensure complete weight transfer.
The initial G-LIFT models were made from fiberglass, which was a very time-consuming process but allowed for several design changes prior to finalizing the most comfortable and effective device design.
Once the final prototype was approved and patented, special molds were handcrafted for a vacuum molding production process.
KYDEX & ALUMINUM
- Kydex was chosen for the lower back and shoulder plate materials because of its lightweight and high tensile strength.
- For the mid-back aluminum bar, both ten degrees angled and straight back G-LIFT.
G-LIFT systems have been trialed with the straight back design felt to provide better posture support over the angled back design. Both are being used based on personal preference. Knowing that space in most Cath labs is limited, the G-LIFT was designed in order to make the unit adjustable to fit each body type and the mid support bar was modified to be self-adjusting for each individual torso. This modification also allowed for the unit to be separated into two parts and easily stored, eliminating the need for the special hinge.
A lumbar support pad was added and provides even more comfort to the lower back when wearing a lead apron with the G-LIFT.
Initially, a stiffer belt was used but the newly designed soft hip belt still provides the necessary support but with more comfort. A non-skid friction strip was added to the aluminum arms so that any apron could be used and securely fitted to the G-LIFT.
- Each part of the G-LIFT is carefully machined, inspected, and assembled by a highly qualified fabricator.
- When fitted appropriately and worn with a tight-fitting vest apron, the G-LIFT acts like a back brace and provides back support and improves posture.
- The separation from the shoulders and neck also improves ventilation and keeps the wearer cooler.
With over three years of development and almost daily use, G-LIFT has been found to be very durable and reliable.
PROFESSIONAL TEAM CONTINUES RESEARCH
Dedicated to understanding and improving this device, the G-LIFT team has been collaborating with the University of North Carolina at Wilmington.
A surface electromyogram (EMG) research study is underway to better understand the muscle activation associated with wearing lead aprons and how the G-LIFT changes muscle activation and transfers the weight of the lead apron.
The G-LIFT is being evaluated at several academic centers, including the following top institutions:
Duke University, Wake Forest University, The University of Florida, and private practice facilities in Tampa and eastern Florida.
Combining the EMG research results and feedback from the above users, further improvements to the G-LIFT design will be ongoing to provide the highest quality and most effective weight transfer system on the market for the wearers of lead aprons.
