Twin Star Medical is a biotechnology and medical device company that is developing porous catheter designs associated with vacuum systems and infusion pumps. Twin Star's technology concept is to produce a catheterâbased treatment option that is designed to perform at three levels: precise local drug infusion, pressure reduction/fluid removal, and tissue monitoring. Because of the pore redundancy, the system is able to provide even delivery/removal along the entire length of the catheter segment. Twin Star's systems have applications in a wide variety of situations, including soft tissue fluid removal and drug delivery in a variety of situations. in 2017, the company's technology for microporous catheters is limited by U.S. federal law to investigational use
