Patent number: 8550089Abstract: A system for delivering therapeutic agent to a target location in a body in accordance with one embodiment is provided comprising a plurality of magnetic particles, each magnetic particle carrying a therapeutic agent, and a magnetic device for attracting the magnetic particles to a target location. The magnetic particles may be delivered by a catheter into a blood vessel upstream from the target location so that they travel toward the target location. A method for delivering therapeutic agent to a target location in a body in accordance with another embodiment comprises providing a plurality of magnetic particles, each magnetic particle carrying a therapeutic agent, placing a magnetic device in a position to attract the magnetic particles to a target location, and allowing the magnetic particles to infuse the target location by the attraction of the magnetic particles to the magnetic device.Type: GrantFiled: April 22, 2010Date of Patent: October 8, 2013Assignee: Boston Scientific Scimed, Inc.Inventors: Aiden Flanagan, Kent Harrison, Liliana Atanasoska, David J. Sogard, Liza J. Davis

Patent number: 8386031Abstract: In one embodiment, the present disclosure provides a biodegradable, self-powered medical device for preventing or reducing reperfusion injury, comprising a galvanic cell, the galvanic cell comprising: a first biodegradable electrode member; and a second biodegradable electrode member comprising a biodegradable conductive polymer and an electrode-releasable therapeutic agent, wherein the galvanic cell generates an electric force sufficient to cause the electrode-releasable therapeutic agent to be released from the biodegradable conductive polymer and elute to a target location. The device may further include a reservoir material containing a burst-release therapeutic agent.Type: GrantFiled: June 29, 2010Date of Patent: February 26, 2013Assignee: Boston Scientific Scimed, Inc.Inventors: Liliana Atanasoska, Aiden Flanagan, Liza J.

Patent number: 8235969Abstract: Devices and methods for transferring forces down a catheter shaft while also maintaining an open fluid pathway are disclosed. In some of the designs, inner and outer members of the catheter interact, allowing improved transfer of forces down the catheter shaft. These designs also allow for maintenance of a fluid pathway along the length of the shaft, including at locations where the inner and outer members are interacting with one another. Structures are disclosed which extend at least a portion of the length of the shaft, allowing improved force transfer and resistance to kinking. Structures are also disclosed which specifically allow for inner and outer members to engage one another at at least one point along the shaft, improving the transfer of forces down the shaft.Type: GrantFiled: March 6, 2006Date of Patent: August 7, 2012Assignee: Boston Scientific Scimed, Inc.Inventors: Daniel Gregorich, Soo-Young Yoon, Liza J. Davis, Tracee E. J. Eidenschink

Patent number: 8173200Abstract: A method of coating an implantable medical device may include providing an implantable medical device, applying a polymer base to the medical device, and directing a first solution including therapeutic agent and solvent through the nozzle onto a target zone of the polymer base coating to penetrate the polymer base coating. The solution may be directed at the target zone until a predetermined concentration of the therapeutic agent can be integrated within the polymer base coating.Type: GrantFiled: May 2, 2008Date of Patent: May 8, 2012Assignee: Boston Scientific Scimed, Inc.Inventors: Liza J. Davis, Thomas Priebe, Kim Robertson

Patent number: 7572625Abstract: A medical device coated with carrier macromolecules, wherein the carrier macromolecules are conjugated with a therapeutic agent. The carrier macromolecules may be antibodies which bind the therapeutic agent at the antigen binding site or by covalent bonding. The carrier macromolecules may be tethered to the surface of or dispersed within a coating on the medical device. The carrier macromolecules may release the therapeutic agent upon exposure to a trigger, which may be exposure to an aqueous environment, or a change in the pH or the ionic strength of the environment. The carrier macromolecules may also be bispecific antibodies directed to both a therapeutic agent and a target antigen. In some cases, binding of the target antigen causes the therapeutic agent to be released from the bispecific antibody. Also provided are methods of controlling the release and targeting of therapeutic agents eluted from a medical device.Type: GrantFiled: May 18, 2006Date of Patent: August 11, 2009Assignee: Boston Scientific Scimed, Inc.Inventors: Liza J. Davis, Kim Robertson, Richard C. Tooley, Jr.
