Wearable, responsive and easy to control, BLOOM43 is designed for use at home as you prepare for surgery, with the effects shown to last many hours. Ultra-precise supraphysiological preconditioningTM can even be used after pre-operative radiotherapy and has been shown to work in two clinical trials. BLOOM43 brings these benefits to every patient in their own home.
Pre-emptively priming your skin to get ready to heal.
The benefits of BLOOM⁴³
In this video, Dr Anushka Chaudhry, an Oncoplastic Breast Surgeon, introduces the concept of supraphysiological preconditioning™ using the BLOOM43 device.
This process intends to contribute to improved wound healing outcomes for breast surgery patients. She explains that up to 1 in 3 breast reconstruction patients experience post-operative complications*, that may lead to revision surgery or implant loss in some cases.
The BLOOM43 device, when used the night before surgery, gently preheats the skin to enhance blood flow and prepare the tissue for healing.
This innovative approach is grounded in clinical evidence and aims to reduce post-operative complications and promote better recovery.

-
Preparing for surgery is a powerful way of preventing complications that might cause prolonged healing times, additional outpatient appointments or possibly even more surgery. BLOOM⁴³ works in harmony with your body, boosting its natural ability to respond to interventions, using the power of supraphysiological preconditioning™. This works by causing the release of naturally occurring heat-shock proteins, which protect our skin from the effects of surgery. They do this by improving the blood flow to the skin through the release of carbon monoxide, a potent vasodilator. The effect of better blood flow means more oxygen gets delivered to your skin. And better blood flow means better healing.
