The expandable assembly is capable of changing from a retracted position to an expanded position. The expandable assembly can be self-expanding or non-self-expanding. In one embodiment, the medical device comprises an elongated member; an umbrella-like expandable assembly which has a plurality of wire elements; and a therapeutic patch. The therapeutic patch comprises a sheet having two opposing surfaces wherein one of the surface comprises an adhesive material and at least one biologically active material. The other opposing surface is disposed onto the plurality of wire elements of the umbrella-like expandable assembly. In another embodiment, the medical device comprises an elongated member, a basket-like expandable assembly having a plurality of wire elements; and a therapeutic patch. The therapeutic patch is disposed onto the plurality of wire elements of the basket-like expandable assembly. | 05-21-2009 |
| 20090131906 | METHOD, SYSTEM, APPARATUS, AND KIT FOR REMOTE THERAPEUTIC DELIVERY - A therapeutic delivery catheter system method or kit for delivery of therapeutic to a target location is provided. In various embodiments of the present invention the invention may include a catheter with a therapeutic delivery lumen and a therapeutic delivery orifice. The lumen and the orifice may be in fluid communication with each other and may be configured such that therapeutic delivered therethrough may be done at pressures mimicking pressures existing or otherwise normal at the target locations receiving the therapeutic. In some embodiments the catheter may be part of a kit that may include instructions regarding the proper manner of operation of the catheter. These instructions may include suggested target pressures for therapeutic delivery as well as delivery times, and suggested lengths of time for the device to reside at the target area after delivery to allow for proper uptake of the therapeutic. | 05-21-2009 |
| 20090138074 | DECELLULARIZED EXTRACELLULAR MATRIX OF CONDITIONED BODY TISSUES AND USES THEREOF - The invention is directed to an apparatus, such as a medical device, having a surface coated or covered with a decellularized extracellular matrix or having a component comprising the decellularized extracellular matrix for implantation into a subject, preferably a human. In one embodiment of the invention, a decellularized extracellular matrix is used to form a bodily implant such as a vein, an artery, an esophagus, or a ventricular restraining device. In some embodiments of the invention, the decellularized extracellular matrix is configured to be a time released therapeutic. In another embodiment of the invention, a decellularized extracellular matrix forms an aneurysm treatment device, such as an aneurysm coil, a seal, a pouch, or a filler. In a further embodiment of the invention, decellularized extracellular matrix is used to embolize lesions, tumors, or vessels. Methods for making the tissue regeneration scaffold and methods for manufacturing a coated or covered medical device having a component comprising decellularized extracellular matrix of body tissues are also provided. | 05-28-2009 |
| 20090138076 | MEDICAL DEVICES FOR DELIVERY OF THERAPEUTIC AGENTS - The present invention is generally directed to medical devices, and more specifically to medical devices that are at least partially insertable or implantable into the body of a patient. The medical devices generally comprise (a) a therapeutic agent, more typically, a high-molecular-weight therapeutic agent, and (b) at least one polymeric layer, which typically acts to control the release of the therapeutic agent from the medical device. Also disclosed herein are methods of making such medical devices. | 05-28-2009 |
| 20090180965 | METHODS FOR REPAIR AND REGENERATION OF BONE MARROW - The invention is directed to a method for treating a tissue or organ in a subject by directly administering an effective amount of an exogenous, decellularized extracellular matrix or a mixture of extracellular matrix and mesenchymal stem cells into the intended site of activity, such as bone marrow cavity. In one embodiment, the invention provides methods of treating bone marrow to increase the number of circulating progenitor and stem cells. In some other embodiments of the invention, the decellularized extracellular matrix to be directly administered is configured to be a time released therapeutic. | 07-16-2009 |
| 20100092448 | LOCAL CONTROL OF INFLAMMATION - A medical device includes a carrier and an agent. The agent is formulated to control inflammation of biological tissue, such as heart tissue, and is releasably coupled to the carrier. The carrier is configured to be disposed in operative proximity to the biological tissue to be treated by the agent. In one embodiment, the carrier is configured to release the agent or otherwise deliver the agent to the biological tissue, thus controlling inflammation of the tissue. Also, a method to improve healing of biological tissue includes placing a medical device proximate to the heart of a patient, where the medical device has a carrier and an agent configured to control inflammation, the agent is releasably coupled to the carrier. In one embodiment, the method includes causing the agent to be released from the carrier. | 04-15-2010 |
| 20100291182 | Drug-Loaded Fibers - Implants and methods for the delivery of a therapeutic agent to a target location within a patient's body are disclosed. The implants include a fiber comprising a polymeric material and having a diameter of up to about twenty microns, and a first therapeutic agent within the fiber. The therapeutic agent is substantially in particulate form. The implants are of a variety of configurations, such as individual fibers, yarns, ropes, tubes, and patches. | 11-18-2010 |
| 20110130715 | Device and Method for Delivering Micronized Therapeutic Agents in the Body - The present invention provides a catheter and catheter assembly for delivering micronized therapeutic agents to a target site in the body and, in particular, to a target site in the heart. The micronized therapeutic agents are delivered in aerosol form or dry powder form. The present invention also provides a method of delivering micronized therapeutic agents to a target site in the body by placing the therapeutic agents in a catheter, positioning the catheter in the target site, and exposing the therapeutic agents to an energizing mechanism sufficient to create supersonic flow to carry the therapeutic agents from a stationary state in the catheter to a mobile state towards the target site. | 06-02-2011 |
