Bioimpedance: a tissue property that defines how electrical current passes through the body; tissues “impede” the flow of current differently depending on the cellular architecture, the underlying cell types, and the health of the tissue. These impedance differences can be sensed in the body by applying small, imperceptible and safe alternating currents between electrodes in contact with the anatomy of interest.
Projects and Clinical Specialties
Cancer
<1%
of prostate tissue is sampled in a standard 12 core biopsy procedure
43%
of pre-operative prostate biopsies differ from post-operative tumor grade
~30%
of radical prostatectomies leave a positive surgical margin, which significantly increases the chance of the cancer recurring
Solution
Impedance-sensing Biopsy Needles
A custom tetrapolar-based impedance biopsy needle enables rapid characterization of surrounding tissue during routine biopsy, increasing prostate sampling volume by 40X and offering spatial guidance to high-grade cells.
Robotically-actuated Surgical Impedance Sensors
Laparoscopic and robotically-compatible, an impedance-based surgical margin probe allows real-time interrogation of tissue for a clean margin during surgery.
Surgical
9.5M
dental implants are placed worldwide every year
40%
iatrogenic injury, including nerve damage, occurs in up to 40% of dental implant cases
>13%
of iatrogenic injuries will suffer permanent effects in the form of chronic pain, lack of sensation or partial facial paralysis
OsteoSmartSense™ Dental Drill
RyTek Medical’s proprietary OsteoSmartSense™ drill system is the first implant drill device to provide dental surgeons real-time impedance sensing technology in order to minimize intra-operative and post-operative surgical complications associated with dental implant procedures
Smart Sensing Surgical Drill
RyTek Medical’s smart sensing drill technology may also offer key surgical guidance in orthopedics and neurosurgery by providing rapid intra-operative feedback to surgeons about approaching high-risk anatomic features during drilling.
Neurological
2nd
Stroke is the second cause of death globally
25%
1 in 4 admitted patients experience stroke progression
30 min
A thirty minute delay in treatment is all it takes to increase your long-term disability odds 11%
Solution
NeuroZ
NeuroZ is a non-invasive intracranial monitor for tracking stroke progression, detecting onset of hemorrhagic events, and alerting clinicians in real-time to high-risk change of pathology.
TBI
Impedance has the potential to be a powerful co-modality to intracranial pressure (ICP) for monitoring and actively managing severe traumatic brain injury (TBI) to improve outcomes.
