Patent number: 10376711Abstract: Light sources are incorporated into a guidewire for enabling the ability to render light therapy be added to catheters that do not have that capability. In one exemplary embodiment, a solid guidewire includes a conductive core, and light sources are added to compartments formed in a distal end of the guidewire. In another exemplary embodiment, a light source array is included in a distal end of a hollow guidewire. A plurality of openings are formed into the walls of the hollow guidewire surrounding the array, enabling light to pass through the openings. Conductors extend from the array though the hollow center of the guidewire, to a proximal end of the hollow guidewire. The hollow guidewire can be coated with a conductive material, so that the coating on the guidewire serves as a conductor.Type: GrantFiled: August 6, 2007Date of Patent: August 13, 2019Assignee: LIGHT SCIENCES ONCOLOGY INC.Inventors: Phillip Burwell, Zihong Guo, Jennifer K. Matson, Steven Ross Daly, David B. Shine, Gary Lichttenegger, Jean M. Bishop, Nick Yeo, Hugh Narciso

Publication number: 20160213945Abstract: A photoreactive agent and a drug therapy device including a support member configured to pass through a urethra having proximal and distal ends and a longitudinal internal lumen. A light generator carried by the support member, potted within the lumen, and positioned within the urethra to deliver light to the prostate. The light generator generates a light band with a peak at a preselected wavelength. A power source external to the support member powers the light generator. The positioning element locates the support member within the urethra. A transparent/translucent, integral window is positioned proximate to the prostate and allows light to pass through. The window extends 360 degrees radially from the support member. The light generator has at least LEDs or LOs having a dimension of approximately 0.3 mm×0.3 mm×0.1 mm (length×width×thickness).Type: ApplicationFiled: April 5, 2016Publication date: July 28, 2016Applicant: PURDUE PHARMACEUTICAL PRODUCTS L.P.Inventors: Phillip Burwell, Zihong Guo, Jennifer K.

Patent number: 8685071Abstract: A method of manufacture and medical apparatus that provides an apparatus useful in illuminating at least a portion of a lumen of a body. The apparatus includes an elongated flexible member and a polymer encasement portion encasing a plurality of light emitters. The light emitters may be electrically coupled to one another without the use of wire bonds, and in some embodiments may be coupled without intervening electrical paths or traces. A maximum cross-sectional dimension of the polymer encasement portion may be less than twice a dimension of one of the light emitters. In some embodiments the maximum cross-sectional dimension is less than or equal to the sum of the dimension of one of the light emitters and a marginal dimension by which an outer portion of the polymer encasement portion extends beyond the light emitter. Light emitters may be arranged linearly, helically or in partially overlapping back-to-back relation.Type: GrantFiled: February 21, 2012Date of Patent: April 1, 2014Assignee: Purdue Pharmaceutical Products L.P.Inventors: Phillip Burwell, James C. Chen, Zihong Guo, Steven R. Daly, David B. Shine, Gary Lichttenegger, Jennifer K. Matson, Jean Bishop, Nick Yeo, Hugh Narciso

Publication number: 20100274330Abstract: Light generating devices for illuminating portions of vascular tissue to administer photodynamic therapy, and usable with, or including a distal protection device. A first device includes a hollow tip, a flushing lumen, a guidewire lumen, and at least one of a light source, and a hollow light transmissive shaft that is adapted to accommodate a light source. If desired, the device can include a balloon, so that a portion of a body lumen between the balloon and the distal protection device is isolated when the balloon is inflated. A second device includes inner and outer catheters, the outer catheter including a balloon, and the inner catheter including a light source encompassed by another balloon. Yet another device is a catheter having two balloons and a sleeve extending there between. Within the sleeve, the catheter includes a light source and an expanding member.Type: ApplicationFiled: July 6, 2010Publication date: October 28, 2010Applicant: Light Sciences Oncology, Inc.Inventors: Phillip Burwell, Zihong Guo, Jennifer K. Matson, Steven Ross Daly, David B. Shine, Gary Lichttenegger, Jean M. Bishop, Nick Yeo, Hugh Narciso, James C. Chen, William L. Barnard, Alexei N. Naimushin
