A cleaning solution may also be delivered to the nasal cavity after treatment to reduce irritation from the iontophoresis.Type: ApplicationFiled: April 4, 2014Publication date: August 7, 2014Inventor: Eduard N.

Publication number: 20140213961Abstract: A system and method for introducing one or more stimulating drugs and/or applying electrical stimulation to the brain to treat mood and/or anxiety disorders uses an implantable system control unit (SCU), specifically an implantable signal/pulse generator (IPG) or microstimulator with one or more electrodes in the case of electrical stimulation, and an implantable pump with one or more catheters in the case of drug infusion. In cases requiring both electrical and drug stimulation, one or more SCUs are used. Alternatively and preferably, when needed, an SCU provides both electrical stimulation and one or more stimulating drugs. In a preferred embodiment, the system is capable of open- and closed-loop operation. In closed-loop operation, at least one SCU includes a sensor, and the sensed condition is used to adjust stimulation parameters.Type: ApplicationFiled: April 2, 2014Publication date: July 31, 2014Applicant: BOSTON SCIENTIFIC NEUROMODULATION CORPORATIONInventors: Todd K.

Patent number: 8790288Abstract: An arteriovenous graft system is described. The arteriovenous graft system includes an arteriovenous graft that is well suited for use during hemodialysis. In order to minimize or prevent arterial steal, at least one valve device is positioned at the arterial end of the arteriovenous graft. In one embodiment, for instance, the arteriovenous graft system includes a first valve device positioned at the arterial end and a second valve device positioned at the venous end. In one embodiment, the valve devices may include an inflatable balloon that, when inflated, constricts and closes off the arteriovenous graft. If desired, a single actuator can be used to open and close both valve devices.Type: GrantFiled: April 9, 2012Date of Patent: July 29, 2014Inventor: David L. Cull

Publication number: 20140207050Abstract: A wound therapy method that results in improved wound healing for conditions including diabetic foot ulcers, pressure ulcers, and arterial and venous ulcers is described. The wound therapy method uses local anesthetic injections in an area surrounding the wound combined with electrical stimulation causing local and deep muscle contraction in the same area. The method leads to increased vasodilation, increased tissue oxygen levels at the target site, and increased blood flow to the target site. This causes local angiogenesis and tissue perfusion that increases wound healing rates and decreases future wound occurrences.Type: ApplicationFiled: January 17, 2014Publication date: July 24, 2014Applicant: Diabetic Neuropathy Network, Inc.Inventors: Victor M. Gonzalez, Francisco J. Gonzalez

Patent number: 8784401Abstract: The steerable catheter comprises a flexible tube, inside of which different conducts are arranged: one or more conducts for drug administration, vacuum conducts associated with different radiofrequency electrodes, conducts for the conductive wires that conducts the radiofrequency energy to the distal end of the catheter, conducts for the fiber optic cable/s that conducts the laser energy to the distal end of the catheter, a guiding wire for the catherization, and another components; the steerable catheter being connected from the proximal end to a energy unit and other pressure and/or dosing devices; and the steerable catheter optionally including an inflatable balloon to help occluding the vessel; and it also incorporates one or two electrode/s or conductive layer/s in the distal end of the catheter; the objective of the steerable catheter being the obtaining of better results in the embolization and/or chemoembolization treatments.Type: GrantFiled: June 30, 2006Date of Patent: July 22, 2014Inventors: Bernard Alfons lucie B. Cambier, Anne Sophie Cecile M. L. De Wulf
