  • Patent number: 7056339
    Abstract: A stent based drug delivery system. A biological agent of interest is entrapped within a matrix, which is loaded into channels on the surface of a stent. The matrix allows for release, usually sustained release, of the entrapped agent. The stent and matrix is sheathed with a covalently bound gel. In one embodiment of the invention, the stent is used to deliver therapeutic agents to a patient, providing the advantage of efficient delivery and sustained release of an agent at a localized site. In another embodiment of the invention, the drug delivery system is used for testing and comparison of candidate drugs in an in vivo setting.

  • Patent number: 7048939
    Abstract: Restenosis is inhibited through local delivery of anti-restenotic agents including angiotensin converting enzyme inhibitors; nicotine receptor agonists, agents that increase concentrations of nitric oxide, anti-angiogenic agents, agonists of the TGF-beta receptor; death domain receptor ligands; and thrombin inhibitors. In one embodiment of the invention, the localized delivery is effected through the use of a stent modified for delivery of the agent at the site of injury from balloon angioplasty.

  • Patent number: 6947862
    Abstract: A method for determining the flow of a fluid (60) in a gap (64) between a pad (48) and a substrate (12) includes the step of utilizing a hybrid Navier-Stokes/lubrication formulation to calculate the flow of the fluid (60) in the gap (64) at a plurality of time steps. The gap (64) can be divided into a plurality of elements (700). The hybrid Navier-Stokes/lubrication formulation can be used to calculate the fluid flow and the pressure of the fluid (60) at each element (700) at the plurality of time steps. Additionally, a method for tracking and estimating the composition of the fluid (60) at various locations in the gap (64) and a material removal rate model that attempts to account for the effects of the fluid flow in the gap (64), the hydrostatic pressure in the gap (64) and the composition of the fluid (60) in the gap (64) are provided herein.
