He holds a total of four patents, showcasing his innovative approach to improving drug delivery systems. His work focuses on enhancing the efficacy of vascular grafts through advanced materials and designs.

Latest Patents

One of Calcote's latest patents is the "Expanded PTFE drug delivery graft." This invention features an improved ePTFE-based delivery graft designed to dispense a bioactive agent, such as a drug, into the bloodstream. The graft incorporates hollow tubing infused with the agent from a drug delivery pump mechanism. The spiral hollow tubing is wrapped around the outer wall of a porous ePTFE graft, allowing the bioactive agent to diffuse into the graft and influence biological processes along both its inner and outer surfaces. This innovative design enables the renewal or change of the bioactive agent after the graft has been implanted.

Another significant patent is the "Dual porosity PTFE tubes." This invention includes a dual porosity PTFE tube with an inner surface of expanded PTFE material having a first porosity and an outer surface with a different porosity. The method involves forming inner and outer preformed tubular billets of PTFE resin particles mixed with a lubricant. By varying the lubrication level and PTFE resin particle size, the porosities of the inner and outer surfaces can be controlled. The resulting PTFE tube exhibits distinct porosities, enhancing its functionality in medical applications.
