摘要:
A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. The scaffold, after being deployed by the balloon, provides a crush recovery of about 90% after the diameter of the scaffold has been pinched or crushed by 50%. The scaffold has a pattern including an asymmetric closed cell connecting links connecting the closed cells.
摘要:
An apparatus for coating implantable medical devices, such as stents, and a method of coating stents using the apparatus is also disclosed. The apparatus includes a barrier or barriers for isolating an area of the stent on which a composition for coating a stent is applied. Two coating compositions can be applied simultaneously to a stent by separate nozzles on different sides of a barrier. Cross-contamination of the compositions is prevented by the barrier.
摘要:
A patterned coating on a prosthesis, for example a stent, and a method for forming the coating are disclosed Additionally, an apparatus for forming the patterned coating is disclosed.
摘要:
The present invention relates to a composition of a first single enantiomer homopolymer and a separate stereocomplex formed of a second single enantiomer homopolymer and it mirror image enantiomer, wherein the first and second single enantiomer homopolymers can be the same or different.
摘要:
Coatings for implantable medical devices and methods for fabricating the same are disclosed. The coating includes polycationic peptides, for example R7.
摘要:
A method of coating a medical device, such as a stent is provided. The method can include forming a polymer layer containing a drug on the device, applying a polymer melt free from any solvents to the polymer layer to form a topcoat layer, wherein the during the application of the polymer melt the migration of the drug from the polymer layer is prevented or significantly minimized.
摘要:
Drug-delivery systems such as drug-delivery stents having an anti-proliferative agent such as everolimus and an anti-flammatory agent such as clobetasol are provided. Also disclosed are methods of treating a vascular impairment such as restenosis or vulnerable plaque.
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.
