Conor's stent design incorporates hundreds of small holes, each acting as a reservoir into which drug-polymer compositions can be loaded. Through this proprietary design, Conor believes that it can greatly enhance control of the rate and direction of drug delivery, enable a wider range of drug therapies, and potentially increase the range of clinical applications of drug eluting stents.

The drug inlay design of Conor's stents allows for greater control of release kinetics, or control over the rate of drug release over time. Since drug release kinetics are controllable by selecting the pattern in which polymers and drugs are loaded into the holes, a wide range of release kinetics can be achieved. Because of Conor's ability to vary the structure of the drug inlay within the reservoirs, Conor believes that its stents are capable of delivering a broad range of compounds, including fat-soluble drugs, water-soluble drugs, proteins, peptides and oligonucleotides. The deep reservoirs of Conor's stents are designed to provide greater dose capacity than thin surface coatings, allowing Conor's stents to potentially deliver more drug for an extended period of time, if required.
