Patent number: 6746446Abstract: An intravascular electrophysiology (EP) device for the mapping and/or formation of lesions along the isthmus region of a heart that has particular utility in the treatment of atrial flutter. The EP device of the invention has an elongated shaft with a proximal section, a compound-curved or modified pigtail-shaped distal section, and a plurality of at least partially exposed electrodes disposed on an outer surface of the distal section. The electrodes are spaced along a length of the distal section and may be interspersed with at least one temperature sensor located between electrodes. The shape of the distal end of the device enables manipulation of the device by inserting its distal end in the tricuspid valve and retracting the device to bias the section having electrodes along the isthmus to achieve acceptable contact with the region so high frequency (e.g., RF) electrical energy delivered to the electrodes on the distal section of the EP device will form a lesion.Type: GrantFiled: August 4, 2000Date of Patent: June 8, 2004Assignee: Cardima, Inc.Inventors: E.

Patent number: 6533768Abstract: Surgical methods and related medical devices for treating glaucoma are disclosed. The method comprises trabecular bypass surgery, which involve bypassing diseased trabecular meshwork with the use of a seton implant. The seton implant is used to prevent a healing process known as filling in, which has a tendency to close surgically created openings in the trabecular meshwork. The surgical method and novel implant are addressed to the trabecular meshwork, which is a major site of resistance to outflow in glaucoma. In addition to bypassing the diseased trabecular meshwork at the level of the trabecular meshwork, existing outflow pathways are also used or restored. The seton implant is positioned through the trabecular meshwork so that an inlet end of the seton implant is exposed to the anterior chamber of the eye and an outlet end is positioned into fluid collection channels at about an exterior surface of the trabecular meshwork or up to the level of aqueous veins.Type: GrantFiled: April 14, 2000Date of Patent: March 18, 2003Assignee: The Regents of the University of CaliforniaInventor: Richard A.

Patent number: 6330586Abstract: A services provision system provides information services over one or more communications networks and has a software infrastructure divided into domains. Each domain has an intelligent software agent and this community of agents sits in a computing environment represented in each domain by a DPE kernel. The community of agents co-operates to provide service and service management functionality to a user. At least one of the agents is reconfigurable to change the functionality the system makes available. Reconfigurability is based on the use of a plurality of reusable software modules, the agent reconfiguring by selecting a new combination of modules. The software modules themselves incorporate rules, or policies, which determine process steps offered by the modules at run-time. These policies are external to the modules and may be loaded at run-time, allowing dynamic modification to functionality of the system.Type: GrantFiled: October 14, 1997Date of Patent: December 11, 2001Assignee: British Telecommunications Public Limited CompanyInventors: Martin John Yates, Ian William Marshall, Julian Richard Hill, Patrick Brian Farley, Mark Bagley

Patent number: 6095147Abstract: Photodynamic therapy is a new adjunctive therapy for filtration surgery that does not use chemotherapy agents or radiation, but uses pharmacologically-active sensitizing compounds to produce a titratable, localized, transient, post operative avascular conjunctiva. A photosensitizing agent in a biological system is selectively activated by delivering the photosensitive agent to the biological system and laser activating only a spatially selected portion of the delivered photosensitive agent. The activated portion of the photosensitive agent reacts with the biological system to obtain a predetermined biological effect. As a result, an improved spatial disposition and effectuation of the biological effect by the photosensitive agent in the biological system is achieved.Type: GrantFiled: December 1, 1994Date of Patent: August 1, 2000Assignee: The Regents of the University of CaliforniaInventors: Richard A.
