Publication number: 20150306311Abstract: An endovascular microvalve device for use in a vessel during a therapy procedure includes an outer catheter, an inner catheter displaceable within the outer catheter, and a filter valve coupled to the distal ends of the inner and outer catheters. The valve is constructed of a braid of elongate first filaments coupled together at their proximal ends in a manner that the first filaments are movable relative to each other along their lengths. A filter is provided to the braid formed by electrostatically depositing or spinning polymeric second filaments onto the braided first filaments. The lumen of the inner catheter delivers a therapeutic agent beyond the valve. The device is used to provide a therapy in which a therapeutic agent is infused into an organ.Type: ApplicationFiled: July 14, 2014Publication date: October 29, 2015Applicant: SUREFIRE MEDICAL, INC.Inventors: Bryan Pinchuk, James E. Chomas

Publication number: 20150238255Abstract: A neuromodulation device includes an ablation valve with electrodes provided about its circumference. The valve dynamically reacts to fluid pressure within the vessel. When a pressure within and distal said ablation valve is greater than the body fluid pressure within the vessel, said ablation valve closes and the electrodes move out of contact with the endothelium of the vessel. When a pressure within and distal the ablation valve is less than the body fluid pressure upstream of the valve, the valve opens such that the electrodes are in circumferential contact with the endothelium. Fluid can be injected into the valve to alter the local pressure about the valve and force the electrodes into contact with the endothelium.Type: ApplicationFiled: May 11, 2015Publication date: August 27, 2015Applicant: SUREFIRE MEDICAL, INC.Inventors: James E. Chomas, Norman R. Weldon, Leonard Pinchuk

Publication number: 20150238666Abstract: A dermatological skin treatment device is provided. The device comprises a handpiece and a cutting tool, wherein the tool is inserted through the conduit and percutaneously inserted into a tissue disposed within a recessed area of the handpiece. The device and method cut the fibrous structures under the skin that cause cellulite at an angle substantially parallel to the surface of the skin and replace these structures with a non-cellulite forming structure by deploying a highly fibrous mesh through a single needle hole to create a highly fibrous layer directly or through wound healing processes. A tool is provided to aspirate excess fluid and tissue from the treatment area.Type: ApplicationFiled: April 28, 2015Publication date: August 27, 2015Inventors: Robert L. Clark, III, James E. Chomas, Adnan I. Merchant, Ben F. Brian, III

Patent number: 9089668Abstract: A flow directional infusion device includes a filter valve located at the distal end of a catheter. The filter valve constrains delivery of an embolic agent through the catheter to the locus of the aneurysm. In order to provide such delivery, the valve includes a longitudinal opening, radial opening or is otherwise partially permeable in a direction of the aneurysm so that the embolic agent or a delivery element for such agent is limited toward the aneurysm. In addition, the filter valve permits and directs blood flow within the blood vessel about the aneurysm during the treatment without obstructing the vessel and without allowing retrograde flow of the embolic agent in the vessel upstream of the aneurysm.Type: GrantFiled: September 12, 2012Date of Patent: July 28, 2015Assignee: SUREFIRE MEDICAL, INC.Inventors: James E. Chomas, Norman R. Weldon, Leonard Pinchuk
