A device having a fluid delivery element is positioned within a lumen of the urethra within the prostate. A fluid stream is directed outwardly from the fluid delivery element toward a wall of the urethral lumen. The fluid delivery element is moved to scan the fluid stream over the wall to remove a volume of tissue surrounding the lumen. The fluid may be combined with therapeutically active substances or with substances that increase resection efficiency. Fluid force may be adjusted to provide selective tissue resection such that soft tissue is removed while harder tissue is left undamaged. In order to gain a working space within the urethra, another fluid may be introduced to insufflate the urethra in the region of treatment.Type: ApplicationFiled: February 4, 2010Publication date: July 28, 2011Applicant: PROCEPT CorporationInventors: Nikolai Aljuri, Ajit Nair, Paren Shah, Adam Nemeyer, Daniel Grupp

Publication number: 20110152744Abstract: Disclosed herein is a modulator of vascular permeability using pulsed laser and a method for modulating vascular permeability using the same. More specifically, because the pulsed laser effectively induces vascular permeabilization, effectively delivers intravascular materials into tissues and minimizes insult to the tissues by the induced vascular permeabilization, and locally targets a subcutaneous tissue for noninvasive modulation due to its nonlinearity, it may be usefully used for modulation of permeability.Type: ApplicationFiled: May 21, 2010Publication date: June 23, 2011Applicant: KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGYInventors: Chulhee CHOI, Myunghwan CHOI

Patent number: 7947067Abstract: This invention is a scanning laser device with a universal carriage that holds any type of optical element. The carriage rotates about an axis that is substantially co-axial to the incident laser beam, thereby causing the laser energy passing through the optical element to sweep through a 360° circle. The preferred embodiment uses a rod lens as the optical element, resulting in a large circular beam spot. The device may utilize laser sources of various wavelengths and pulse frequencies, and multiple devices may be combined to scan an even larger area.Type: GrantFiled: April 20, 2006Date of Patent: May 24, 2011Assignee: Erchonia CorporationInventors: Kevin Tucek, Steven C. Shanks, Lawrence Owens

Patent number: 7912539Abstract: A system for applying a polymer (hydrogel) to the inner surface of a vessel by photopolymerization includes a catheter having a first inflatable member and a guidewire having a second inflatable member. The catheter has an extended tip distal to the first inflatable member that includes multiple perfusion ports. A light emission coil is disposed on the extended tip with individual coil loops interspaced with the perfusion ports. In a method, the guidewire is delivered to a treatment site within a vessel. The catheter is delivered to the treatment site over the guidewire. The inflatable members are inflated to form an enclosed treatment space within the vessel. A photoinitiator is delivered to the enclosed treatment space. Excess photoinitiator is flushed from the treatment space, and a prepolymer is delivered. The prepolymer is cured by light delivered by the light emission coil.Type: GrantFiled: February 2, 2009Date of Patent: March 22, 2011Assignee: Medtronic Vascular, Inc.Inventors: David Doty, Feridun Ozdil, Josiah Wilcox, Robret Murray, Prasad Kilari

Patent number: 7897181Abstract: The present invention relates to an agent for photodynamic therapy (PDT) containing porous silicon (PSi) and a method of quantitative measurement of reactive oxygen species (ROS) produced therefrom. Particularly, it is expected that the present invention will contribute to the development of cancer treatment without side effects by suggesting PSi, a safe and reliable new cancer drug that can destroy cancer cells through generating sufficient heat with little ROS produced if the PSi is used as nanobomb for a new PDT that kills cancer cells with heat or explosion. In addition, it is expected that the present invention will provide a reliable and reproducible method for quantitative measurement of a very small amount of ROS produced therefrom through an XRD analysis.Type: GrantFiled: October 11, 2007Date of Patent: March 1, 2011Assignee: Inha-Industry Partnership InstituteInventors: Chongmu Lee, Youngjoon Cho, Hojin Kim
