Intramuscular Microvascular Flow Sensing for Flap Monitoring in a Porcine Model of Arterial and Venous Occlusion.
[BACKGROUND] Commercially available near infrared spectroscopy devices for continuous free flap tissue oxygenation (StO) monitoring can only be used on flaps with a cutaneous component. Additionally, differences in skin quality and pigment…

A Wireless Near-Infrared Spectroscopy Device for Flap Monitoring: Proof of Concept in a Porcine Musculocutaneous Flap Model.
[BACKGROUND] Current near-infrared spectroscopy (NIRS)-based systems for continuous flap monitoring are highly sensitive for detecting malperfusion. However, the clinical utility and user experience are limited by the wired connection betw…

Intramuscular Near-Infrared Spectroscopy for Muscle Flap Monitoring in a Porcine Model.
[BACKGROUND] Current near-infrared spectroscopy (NIRS)-based systems for continuous flap monitoring are limited to flaps which carry a cutaneous paddle. As such, this useful and reliable technology has not previously been applicable to mus…

Implantable, wireless, self-fixing thermal sensors for continuous measurements of microvascular blood flow in flaps and organ grafts.
Vascular pedicle thrombosis after free flap transfer or solid organ transplantation surgeries can lead to flap necrosis, organ loss requiring re-transplantation, or even death. Although implantable flow sensors can provide early warning of …
