Latest Patents

Ashley Rook holds 1 patent for his invention titled "Electrically conductive hydrogels usable as lead extensions, apparatus for delivery of a hydrogel into the vasculature, and methods of treating ventricular arrhythmia with electrically conductive hydrogels injected in the venous system." This patent describes a conductive hydrogel precursor solution that cures after being injected into the vasculature of the myocardium. The vasculature serves as a mold for the hydrogel, allowing for a pacing signal to be conducted across the myocardium rather than at a single point, as is the case with traditional pacing leads. The catheter-based delivery system enables precise placement of the hydrogels into the myocardial veins, effectively filling the venous tributaries. In situ crosslinking of the hydrogel precursor solution is achieved through various mechanisms, including redox initiation by mixing a reducing reagent and oxidizing agent post-injection. Conductivity is enhanced by doping with conductive polymers or other elements such as ionic species, metallic nanoparticles, or graphene nanoplatelets. To ensure long-term conductivity, hydrogel macromers are synthesized without hydrolytically labile groups, and conductive elements are conjugated directly to the hydrogel matrix.
