摘要:
The present invention relates to implantable medical devices coated with phosphoryl choline acrylate polymer topcoat layer, an acrylate copolymer layer containing a therapeutic agent, and their use in the treatment of vascular diseases.
摘要:
A system or device for spin coating an implantable medical device, such as a stent, is disclosed. The device includes a coating table to support the stent, the stent being positioned on top of the coating table and supported on the table by a support fixture. The coating table has an axis of rotation. The axis of rotation of the table can intersect a center of the mass of the stent. A driving means can be provided for rotating the stent about the longitudinal axis of the stent and for rotating the coating table about the axis of rotation.
摘要:
A stent comprising a coating layer is disclosed. The coating layer has a hydrophobic component and a hydrophilic component, wherein a region of the coating layer on or about the outermost surface of the coating layer has a higher content or concentration of the hydrophilic component than the hydrophobic component.
摘要:
A porous three-dimensional bone grafting matrix is provided which is biodegradable. The matrix is preferably formed from mineralized collagen where the mineral comprises particulate calcium phosphate immobilized in the matrix and having a particle size of 5 microns or less.
摘要:
Coatings for implantable devices or endoluminal prosthesis, such as stents, are provided, including a method of forming the coatings. The coatings can be used for the delivery of an active ingredient or a combination of active ingredients.
