摘要:
A method and apparatus for the provision of a coating for application to a medical device results in a medical device having a bio-absorbable coating. The coating includes a bio-absorbable carrier component. In addition to the bio-absorbable carrier component, a therapeutic agent component and solvent can also be provided. The solvent is removed from the coating before the coating is applied to the medical device. The coated medical device is implantable in a patient to effect controlled delivery of the coating, including the therapeutic agent, to the patient.

Methods and devices for the provision of a coating on an implantable medical device. The coating includes a bio-absorbable carrier component. In addition to the bio-absorbable carrier component, a therapeutic agent component can also be provided. The methods and devices provide a coating having improved uniformity and coverage which in turn allow for greater control of the amount and dosage of the coating.
摘要:
A non-polymeric or biological coating applied to a radially expandable interventional medical device in a collapsed, wrapped, or folded configuration. Properties of the coating material applied to the medical device are adjusted or varied to result in a desired combination of coverage of the surface of the medical device, drug loading, and coating thickness. The coating is sterile, and is capable of being carried by a sterile medical device to a targeted tissue location within the body following radial expansion. The therapeutic coating transfers off the medical device due in part to a biological attraction with the tissue and in part to a physical transference from the medical device to the targeted tissue location in contact with the medical device.

摘要:
A therapeutic agent-eluting stylet treats a catheter by at least temporarily locating the stylet in a lumen of an indwelling catheter placed into a patient. The therapeutic agent-carrying stylet provides a localized therapeutic effect to the catheter and patient by eluting one or more therapeutic agents directly into the lumen of the catheter, into the fluid within the catheter, into the fluid and tissue in contact with the catheter, and onto the surface of the catheter. By removal and replacement of the temporary stylet from the catheter, renewable therapeutic agent doses can be provided to a component, such as the lumen, of the catheter while the catheter remains within in a patient. One or more therapeutically effective doses of medicated agents can be tailored along the length of the stylet and controlled by the length of time by which the stylet remains installed in the catheter.
摘要:
A non-polymeric or biological coating applied to porous radially expandable interventional medical devices provides uniform drug distribution and permeation of the coating and any therapeutic agents mixed therewith into a targeted treatment area within the body. The coating is sterile, and is capable of being carried by a sterile medical device to a targeted tissue location within the body following radial expansion. The therapeutic coating transfers off the medical device due in part to a biological attraction with the tissue and in part to a physical transference from the medical device to the targeted tissue location in contact with the medical device. Thus, atraumatic local tissue transference delivery is achieved for uniform therapeutic agent distribution and controlled bio-absorption into the tissue after placement within a patient's body with a non-inflammatory coating.

摘要:
A non-polymeric or biological coating applied to radially expandable medical delivery device provides uniform drug distribution and permeation of the coating and any therapeutic agents mixed therewith into a targeted treatment area within the body. The delivery device is expanded using the pressure of an inflation fluid. After expanding the delivery device to a pre-determined size and shape, the inflation fluid weeps through the porous surface of the delivery device. The coating releases the delivery device and floats on the inflation fluid until bonding to the tissue due to its affinity for the tissue. Once the coating bonds or affixes to the tissue, through an absorption mechanism by the tissue cells of the coating material, the coating and any therapeutics contained therein are delivered to the tissue. The fluid can contain a therapeutic agent, or can be otherwise biocompatible and/or inert.
