  • Publication number: 20060110457
    Abstract: A method of curing and corresponding resulting non-polymeric cross-linked gel are provided. The cross-linked gel can be combined with a medical device structure. The cross-linked gel can provide anti-adhesion characteristics, in addition to improved healing and anti-inflammatory response. The cross-linked gel is generally formed of a naturally occurring oil, or an oil composition formed in part of a naturally occurring oil, that is at least partially cured forming a cross-linked gel derived from at least one fatty acid compound. In addition, the oil composition can include a therapeutic agent component, such as a drug or other bioactive agent. The curing method can vary the application of heat in both temperature and duration to achieve a desired amount of cross-linking forming the gel.

  • Publication number: 20060058737
    Abstract: 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.

  • Publication number: 20050261639
    Abstract: A medicated ink marker includes a porous applicator and at least one medicated agent disposed within the porous applicator. The medicated ink marker makes no use of a reservoir from which to draw the at least on medicated agent. The at least one medicated agent is one of a non-antiseptic medicated agent and an antiseptic with an additional therapeutic function medicated agent. The porous applicator supports capillary action, such that contact of the applicator against a targeted location results in the at least one medicated agent dispensing from the porous applicator to topically apply the at least one medicated agent to the targeted location in a detectable manner without drawing additional medicated agent from another location, such as a reservoir.

  • Publication number: 20050251152
    Abstract: An illuminated medicated ink marker provides a user with the ability to apply and confirm a dosage amount of a drug or agent applied in the form of a liquid, such as an ink, to create the marking, in environments that are otherwise not well lit. The illuminated medicated ink marker includes a holder for controlling the medicated ink marker. A marking portion is coupled with the holder and configured to transfer medicated ink from within the medicated ink marker to a targeted location. An illumination source is coupled with the holder. The illumination source is disposed to illuminate a clinical field including at least a portion of the targeted location.

  • Patent number: 6955661
    Abstract: A radially expandable fluid delivery device for delivering a fluid to a treatment site within the body is disclosed. The fluid delivery device is constructed of a microporous, biocompatible fluoropolymer material having a microstructure that can provide a controlled, uniform, low-velocity fluid distribution through the walls of the fluid delivery device to effectively deliver fluid to the treatment site without damaging tissue proximate the walls of the device. The fluid delivery device includes a tubular member defined by a wall having a thickness transverse to the longitudinal axis of the tubular member and extending between an inner and an outer surface. The wall is characterized by a microstructure of nodes interconnected by fibrils. The tubular member is deployable from a first, reduced diameter configuration to a second, increased diameter configuration upon the introduction of a pressurized fluid to the lumen.

  • Patent number: 6923927
    Abstract: The invention is directed to methods involving rewetting of expandable polymers with a wettable liquid to allow for enhanced expansion at or below room temperature without breakage, and in some cases, allows one to achieve a greater expansion ratio than that allowed at elevated temperatures using known methods. The wettable liquid can be formed of a drug and/or an agent, such that the resulting polymer contains and emits the drug upon positioning at a target location of a patient body. The expandable polymer can also have the drug or agent added to its structure at a polymer resin preparation stage, through use of an aqueous solution mixed with one or more fluoropolymers, or in a mixing stage. The present invention also allows one to achieve material with unique properties and handling characteristics. These properties included decreased material thickness, increased density, an altered node/fibril morphology, and a more consistent web in the case of flat material.

  • Publication number: 20050154416
    Abstract: A method of making a radially expandable fluid delivery device includes providing a tube of biocompatible fluoropolymer material with a predetermined porosity based on an extrusion and expansion forming process, applying a radial expansion force to the tube expanding the tube to a predetermined diameter dimension, and removing the radial expansion force. The tube is radially inelastic while sufficiently pliable to be collapsible and inflatable from a collapsed configuration to an expanded configuration upon introduction of an inflation force, such that the expanded configuration occurs upon inflation to the predetermined diameter dimension. The fluid delivery device is constructed of a microporous, biocompatible fluoropolymer material having a microstructure that can provide a controlled, uniform, low-velocity fluid distribution through the walls of the fluid delivery device to effectively deliver fluid to the treatment site without damaging tissue proximate the walls of the device.

  • Publication number: 20050113687
    Abstract: 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.
