Abstract: Methods of reducing crimping damage to polymer and drug coating on a scaffold are disclosed. The methods include physically aging a coating including a coating polymer and drug mixture on a scaffold in a manner that takes into account the differing kinetics of aging, that is, the different temperature dependence of the aging rate of the polymer and drug.

Abstract: An engine system includes an internal combustion engine, a driven unit, and a torsional coupling between a crankshaft of the engine and a driveshaft of the driven unit. The torsional coupling includes a driven-side disc coupled to the driveshaft, and a flywheel having an engine-side disc coupled to the crankshaft. The engine-side disc has an axial thickness in a discontinuous thickness range from about 0.2 inches to about 0.3 inches, so as to flex the engine-side disc predominantly over the driven-side disc in response to the driveline deflecting loads.

Abstract: A firing deck (16) for an engine crankcase includes a firing side surface (35) and a coolant side surface (34). A plurality of cylinder bores (18) are disposed through the firing deck (16) from the firing side surface (35) to the coolant side surface (34). The cylinder bores (18) form a centerline defining an intake side (26) of the firing deck (16) and an exhaust side (28) of the firing deck. A plurality of bosses (30) through the deck (16) from the firing side surface (35) to the coolant side surface (34) are disposed around each cylinder bore (18). A plurality of anti-distortion projections (36, 136) are disposed on the coolant side surface (34) of the firing deck (16) and provide the firing deck with a varied thickness. The anti-distortion projections (36, 136) are disposed on both the intake side (26) and the exhaust side (28) of the firing deck (16).

Abstract: This invention is generally related to coatings for implantable medical devices, such as drug delivery vascular stents. The coating includes a drug reservoir layer above the outer surface of the device body, the drug reservoir layer with a peptide or protein, a hydrophobic drug, and a polymer with a weight average molecular weight between about 10,000 to about 150,000 Daltons. A preferred polymer is a poly(ester amide) polymer.

Abstract: This invention is generally related to methods of forming coatings for implantable medical devices, such as drug delivery vascular stents. The methods are for forming coatings to control the release of a peptide such as RGD, and a hydrophobic drug. Both single layer and multiple layer coating constructs are encompassed in the various embodiments of the present invention.

Abstract: An apparatus for measuring the amount of various corrosive gases present in a corrosive environment, which uses a metal plate having a thin metalic film thereon formed by sputtering or deposition, instead of the conventional hand made metal sheet, and which measures the thickness of a corrosion film formed on the metal film by utilizing an X-ray spectrum instead of the conventional cathode reduction method, and without destroying the corrosion film, through use of a calibration curve. The invention also provides a novel casing for holding the metal plate in the corrosive environment during measurement.
