A method and device for local delivery of water-soluble or water-insoluble therapeutic agents to the surface of a normal or diseased body lumen is disclosed. An expandable structure of a medical disposable device, such as a balloon of a balloon catheter, is coated with an amphiphilic polymer coating comprising a therapeutic agent and an amphiphilic polymer or co-polymer. The medical disposable device is inserted into a body lumen, and expanded to contact the amphiphilic polymer coating against the body lumen. The total solubility of the polymer or co-polymer in vivo prevents any embolic hazard associated with the amphiphilic polymer coating.

Local delivery of water-soluble or water-insoluble therapeutic agents to the surface of body lumens

In some embodiments, a device () may include a mesh having at least one bioresorbable polymer coating. The coating may comprise at least one active agent which is eluted over time. The device () may at least partially cover at least a portion of an implanted transdermal medical device ().

Drug eluting mesh to prevent infection of indwelling transdermal devices

The present disclosure is directed to a catheter for site-specific delivery of a therapeutic agent to a blood vessel of a patient. The catheter further includes an elongated shaft having at least one inner lumen, a distal end and a proximal end and proximal and distal vessel-conforming balloons where each is separately positionable and inflatable, and when inflated, substantially restricts blood flow in the vessel and creates a treatment window of a defined but variable length for delivery of the therapeutic agent. The catheter optionally includes at least one marker band adjacent to the proximal balloon and at least one marker band adjacent to the distal balloon. At least one lateral aperture positioned in the window is in fluid communication with a drug delivery conduit located within either the inner shaft or the outer shaft to provide a homogeneous concentration of the therapeutic agent to the window.

Double balloon catheter and methods for homogeneous drug delivery using the same

A method and device for local delivery of water-soluble or water-insoluble therapeutic agents to the tissue of a normal or diseased body lumen is disclosed. An expandable structure of a medical disposable device, such as a balloon of a balloon catheter, is coated with a non-durable coating which is complexed with iodine and has a substantially water-insoluble therapeutic agent dispersed therein. The medical disposable device is inserted into a body lumen, and expanded to contact the non-durable coating against the body lumen and deliver the substantially water-insoluble therapeutic agent to the body lumen tissue.

The invention, in one embodiment, is directed to a catheter for site-specific delivery of a therapeutic agent to a blood vessel of a patient. The catheter further includes an elongated shaft having at least one inner lumen, a distal end and a proximal end and proximal and distal vessel-conforming balloons where each is separately positionable and inflatable, and when inflated, substantially restricts blood flow in the vessel and creates a treatment window of a defined but variable length for delivery of the therapeutic agent. The catheter optionally includes at least one marker band adjacent to the proximal balloon and at least one marker band adjacent to the distal balloon. At least one lateral aperture positioned in the window is in fluid communication with a drug delivery conduit located within either the inner shaft or the outer shaft to provide a homogeneous concentration of the therapeutic agent to the window.
