摘要:
A process for making an implantable material comprising a composite of a biocompatible polymer and a bioactive agent. The composite combines desirable mechanical properties of polymers and the bioactivity of tissue or one or more component of tissue. More particularly, but not exclusively, the invention relates to methods for the manufacture of implantable materials, devices and components via a powder molding process.

Compounds that include diorgano groups having quaternary carbons and optionally urethane groups, urea groups, or combinations thereof (i.e., polyurethanes, polyureas, or polyurethane-ureas), as well as materials and methods for making such compounds.
摘要:
An implantable medical device such as a defibrillator is described. The device includes an hermetically sealed housing containing a flat electrolytic capacitor and an energy source such as a battery. The battery is connected to the capacitor and provides charge thereto. The capacitor stores the charge at a relatively high voltage. The charge stored in the capacitor is discharged through a defibrillation lead to a site on or in the heart when fibrillation of the heart is detected by the implantable medical device. Methods of making and using the implantable medical device, the capacitor, and their various components are disclosed.
摘要:
Implantable medical devices (IMDS) having anti-infective properties are described. Anti-infective agents are disposed in, on, or about at least a portion of a surface of the medical device. The anti-infective agents are disposed in or on a vehicle, which may be in the form of a coating layer or covering. The vehicle may be biodegradable so that, over time, the anti-infective agent is removed from a tissue location into which the device is implanted, reducing the likelihood that microorganisms resistant to the anti-infective agent will develop. IMDs having an anti-infective agent and an anti-activity agent disposed therein, thereabout, or thereon are also described. The anti-activity agent interferes with the activity of the anti-infective agent, may be released from a surface at the IMD at a time when activity of the anti-infective agent is no longer desired, and may reduce the likelihood that microorganisms resistant to the anti-infective agent will develop.

摘要:
Methods and kits for treating infection associated with implantation of a medical device use of minocycline and rifampin microparticles. The microparticles, in a suitable medium, can be injected in a patient in proximity to the device. The drugs may be configured to be released from the polymer matrix in a controlled manner by manipulation of the properties of the polymer forming the microparticle. By injecting the drugs in the form of microparticles, the drugs can be distributed in a manner so that the entire pocket is protected without affecting device function. The microparticles can be produced aseptically without affecting the manufacturing of the device.

摘要:
Poly(orthoester) polymers, and methods of making and using such poly(orthoester) polymers are provided. The poly(orthoester) polymers can be useful for applications including, for example, medical devices and pharmaceutical compositions. In a preferred embodiment, the poly(orthoester) polymers are biodegradable.
