The present disclosure teaches methods of controlling the release rate of agents from a polymeric matrix. The methods relate to the application of pressure, and optionally, in combination with heat, to a polymeric coating.

Methods of treatment of polymeric coatings for control of agent release rates

The present invention provides a semi-crystalline polymer for a coating on an implantable device for controlling release of drug and methods of making and using the same.

Bioabsorbable semi-crystalline polymer for controlling release of drug from a coating

A therapeutic agent delivery system formed of a specific type of poly(ester amide) (PEA), a therapeutic agent, and a water miscible solvent is described herein. A method of delivering the therapeutic agent delivery system by delivering the therapeutic agent delivery system formed of a PEA polymer, a therapeutic agent, and a water miscible solvent to a physiological environment and separating the phase of the therapeutic agent delivery system to form a membrane from the polymer to contain the therapeutic agent within the physiological environment is also described. Additionally disclosed is a kit including a syringe and a therapeutic agent delivery system within the syringe.

Polyesteramide platform for site specific drug delivery

A bioabsorbable scaffold composed of a multilayer structure of alternating layers of different polymers is disclosed. The multilayer structure can have 20 to 1000 layers and the individual thickness of the layers can be 0.2 to 5 microns. A method of making the scaffold including a layer multiplying extrusion process is disclosed.

Multilayer bioabsorbable scaffolds and methods of fabricating

Methods are disclosed for chemically stabilizing a polymer stent after sterilization. The stent is exposed to a temperature above ambient for a period of time after radiation sterilization. The exposure reduces the concentration of free radicals generated by the radiation.

Post electron beam stabilization of polymeric medical devices

Methods for fabricating a polymeric stent with improved fracture toughness including radial expansion of a polymer tube and fabricating a stent from the expanded tube are disclosed. The polymer tube is disposed within a mold and may be heated with radiation. The heated tube radially expands within the mold.

Tube expansion processes for semicrystalline polymers to maximize fracture toughness

Methods to expand polymer tubing with desirable or optimum morphology and mechanical properties for stem manufacture and fabrication of a stent therefrom are disclosed.

Controlling crystalline morphology of a bioabsorbable stent

Methods of fabricating a polymeric implantable device, such as a stent, with improved fracture toughness through annealing a polymer construct below the glass transition temperature of the polymer of the construct prior to a deformation step are disclosed herein. The deformation of the construct induces crystallization in the polymer construct through strain-induced crystallization. The annealing of the polymer construct accelerates the crystallization induced during the deformation and results in an increase in crystallite density with smaller crystallites as compared to deformation of a tube that has not been annealed. A stent scaffolding is then made from the deformed tube.
