Patent number: 7985214Abstract: An intravascular catheter that exhibits the combined features of superior flexibility, softness, radiopacity and oval/kink resistance. The catheter includes an elongate shaft having a proximal region, a distal region and a lumen extending therethrough. The proximal region of the shaft includes an inner lubricious polymer layer, a reinforcement layer and an outer layer. The reinforcement layer comprises a braid having one or more metallic members and a plurality of polymer members wherein each polymer member comprises a plurality of monofilaments, preferably formed of LCP. The polymer members of the braid provide improved flexibility and softness in addition to high burst pressure. The metallic member(s) of the braid provide improved radiopacity and oval/kink resistance. The catheter may also include a longitudinal member extending along the reinforcement layer.Type: GrantFiled: January 19, 2005Date of Patent: July 26, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Robert J.

Patent number: 7964209Abstract: The present invention provides a method for the formation of a medical device that comprises a therapeutic agent and a release region, which regulates the rate at which the therapeutic agent is released from the medical device. The method comprises providing a precursor region that comprises a polymer composition comprising two or more microphase separated polymer domains that are immiscible with one another, and forming said release region by a process that comprises applying an orienting field comprising an electric field, a magnetic field, a mechanical shear field, or a solvent gradient field, or a combination of two or more fields to said precursor region, wherein said field or combination of fields changes the spatial orientation of the microphase separated polymer domains within the release region. The electric, magnetic, mechanical shear or solvent gradient field is of sufficient strength to change the spatial orientation of the microphase separated domains.Type: GrantFiled: December 7, 2004Date of Patent: June 21, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Shrirang V. Ranade, Robert E. Richard, Kinh-Luan (Lenny) D. Dao, Samuel P. Gido, Akinbode Idowu Isaacs-Sodeye

Patent number: 7402172Abstract: The present invention includes systems, methods and apparatus. A system in accord with the present invention may include an intraluminal patch sized to fit within a lumen and an expandable therapeutic delivery device. The patch in this embodiment may have an adhesive region on an exposed surface and a drug reservoir region in communication with the exposed surface. By comparison, a method employing the present invention may include placing an intraluminal patch over an expandable delivery device, advancing the delivery device and the expandable patch to a target site, expanding the delivery device so that the patch adheres to the target site, and contracting and withdrawing the delivery device. In so doing the patch may remain to emit a drug to the target site over a sustained period of time.Type: GrantFiled: October 13, 2004Date of Patent: July 22, 2008Assignee: Boston Scientific Scimed, Inc.Inventors: Yem Chin, (Lenny) Kinh-Luan D.
