Provided is a coated implantable medical device, comprising: a substrate; and a coating disposed on said substrate, wherein said coating comprises at least one polymer and at least one pharmaceutical agent in a therapeutically desirable morphology and/or at least one active biological agent and optionally, one or more pharmaceutical carrying agents; wherein substantially all of pharmaceutical agent and/or active biological agent remains within said coating and on said substrate until the implantable device is deployed at an intervention site inside the body of a subject and wherein upon deployment of said medical device in the body of said subject a portion of said pharmaceutical agent and/or active biological agent is delivered at said intervention site along with at least a portion of said polymer and/or a at least a portion of said pharmaceutical carrying agents.

Drug delivery medical device

In one aspect, the present invention provides composite coatings for implantable or insertable medical devices. These composite coatings comprise (a) an inorganic portion and (b) a polymeric portion that comprises a poly(vinyl pyrrolidone) (PVP) block.

Polymeric/ceramic composite materials for use in medical devices

The invention provides nanodevices or products of manufacture for use as drug delivery vehicles. In one aspect, the invention provides nanodevices or products of manufacture having on-off release mechanisms, e.g., that are “switchable”, or “actuatable” (for example magnetically or ultrasonically switchable), for compounds contained within, e.g., for use as drug delivery nano-vehicles having on-off drug release mechanisms, and their therapeutic applications.

Switchable nano-vehicle delivery systems, and methods for making and using them

A method for depositing a coating comprising a polymer and pharmaceutical agent on a substrate, comprising the following steps: discharging at least one pharmaceutical agent in a therapeutically desirable morphology in dry powder form through a first orifice; discharging at least one polymer in dry powder form through a second orifice; depositing the polymer and/or pharmaceutical particles onto said substrate, wherein an electrical potential is maintained between the substrate and the pharmaceutical and/or polymer particles, thereby forming said coating; and sintering said coating under conditions that do not substantially modify the morphology of said pharmaceutical agent.

Polymer coatings containing drug powder of controlled morphology

Provided herein is a device comprising: a stent; b a plurality of layers on said stent framework to form said device; wherein at least one of said layers comprises a bioabsorbable polymer and at least one of said layers comprises one or more active agents; wherein at least part of the active agent is in crystalline form

Stents having controlled elution

An implantable medical device including a nanocomposite coating deposited on at least a portion of a surface to provide a controlled release of a bioactive agent in one or more dosages is described. The nanocomposite coating includes a matrix, a bioactive agent and inorganic particles. The inorganic particles respond to a stimulus, preferably by generating heat. The response of the particles to the stimulus causes the matrix of the nanocomposite coating to undergo a volume change by, for example, contracting or swelling, thereby releasing at least a portion of the bioactive agent. A method of providing a controlled release of a bioactive agent from a nanocomposite coating on an implantable medical device is described. A method for preparing an implantable medical device coated with a nanocomposite coating for the controlled release of a bioactive agent is also described.
