  • Publication number: 20230146898
    Abstract: A minimally invasive circulatory support device, system, and related methods. The circulatory assist devices, systems, and methods use low profile catheter-based techniques and provide temporary and chronic circulatory support depending on the needs of the patient. The circulatory assist device, systems, and methods include a stent cage and an impeller. The stent cage is formed of a first material that is sufficiently rigid to expand radially outward and press against an artery wall is sufficiently deformable to collapse within the outer sheath. The impeller includes at least one blade formed of a second material that is sufficiently rigid to expand and retain shape while rotating and assisting blood to flow within the artery and is sufficiently deformable to collapse within the outer sheath with the stent cage.

  • Publication number: 20220409894
    Abstract: Described is precise bioelectrical stimulation of a subject's cellular tissue with a selected bioelectric signal to modulate the expression of a peptide by the cellular tissue. More specifically, the application relates to a device that delivers a programmed bioelectric signal or signals, and associated methods for the controlled modulation of a peptide, such as vascular endothelial growth factor (VEGF) and/or hypoxia-inducible factor 1-alpha (HIF1?), or manipulation of stem cells, via precise bioelectrical signals and sequences useful in, for example, orthodontic and other procedures. The bioelectric signals have preferably been further optimized by selecting a desired pulse width for the peptide(s) to be expressed.

  • Publication number: 20220117719
    Abstract: Described is an intravascular device including a stent structure and at least one annular band.

  • Patent number: 11185691
    Abstract: Described are a system and method that “reads” cancer tumors real time and custom delivers individualized bioelectric therapy to the patient. For example, the system reads a cancer tumor, and based upon this read, delivers to the subject “a confounding signal” to jam communication within that tumor. A cancer tumor may change its communication patterns and the therapy is designed to change with these patterns, attempting to always jam the relevant communication signaling pathway. The described system includes parameters not tied to communication jamming, which should also be customized to induce apoptosis to the cancer tumor. Such parameters include signals for starving a cancer tumor of blood supply and signals for changing the cancer tumor's surface proteins and/or charge so that the immune system attacks the cancer tumor.

  • Patent number: 11167141
    Abstract: Described are a system and method that utilize bioelectric signaling to balance electrical potentials in a subject's body via neuro-hormonal circuit loops, to increase elasticity of the subject's arteries to promote protein release to dampen arterial blood pressure, and to change arterial electrical charges to reduce narrowing of the arteries. The described system is designed to localize and stimulate the fibers inside the vagus nerve without inadvertent stimulation of non-baroreceptive fibers causing side effects like bradycardia and bradypnea. The system also controls release of specific proteins known to lower blood pressures including tropoelastin (known to increase elasticity in the aorta and other peripheral blood vessels).

  • Publication number: 20210339018
    Abstract: A skin regeneration therapy combining precise bioelectric signals, light, and biologics for skin treatment and regeneration. Precise bioelectric signals give clear instructions to the stimulated cell DNA/RNA to produce specific regenerative proteins on demand. Bioelectric signals give clear instructions to cell membranes on what to let in and what to let out and serve as an equivalent or surrogate of environmental stimuli to cause a cell action in response.
