Publication number: 20200038586Abstract: A therapeutic agent delivery system includes a catheter, a vascular occluder, a pressure sensor system, and a pump system. The vascular occluder is provided at the distal end of the catheter. The pressure sensor system is provided to sense pressure at the distal end of a catheter lumen, and provides feedback to the pump system. The pump system is adapted to control the rate of infusion of the therapeutic agent through the lumen of the catheter based on the pressure sensed by the pressure sensor system. A method includes deploying the occluder in a vessel, and then sensing a pressure in the vessel. The therapeutic agent is infused into the vessel at a flow rate based on the sensed pressure.Type: ApplicationFiled: May 9, 2019Publication date: February 6, 2020Applicant: Surefire Medical, Inc.Inventors: James E.

Patent number: 10548659Abstract: A needle with multiple injection ports is used in connection with a high-pressure injection system to infuse a treatment solution into a treatment area below the dermis of the skin. The needle has multiple tines that extend outwardly from the injection ports while inside the treatment area to disrupt tissue in the treatment area and to create multiple pathways of infusion. The tines are withdrawn and the needle is partially withdrawn, and solution is injected from the needle into the treatment area at high pressure to infuse the tissue within the treatment area. The burst, infusion, and a treatment such as an energy or third solution may be interleaved and repeated multiple times.Type: GrantFiled: September 8, 2009Date of Patent: February 4, 2020Assignee: ULTHERA, INC.Inventors: James E.

Publication number: 20180250469Abstract: A method includes providing microvalve device having inner and outer catheters, and a filter valve attached to the distal end of the inner and outer catheters. Longitudinal displacement of the inner catheter relative to the outer catheter moves the filter valve from a non-deployed configuration to a deployed configuration. With the inner catheter longitudinally advanced a first amount relative to the outer catheter, the filter valve is in a reduced first diameter for advancement of a guidewire to a target location. Once the filter valve reaches the target location, the inner catheter is moved relative to the outer catheter such that the filter valve assumes a larger second diameter. A therapeutic agent is infused through the inner catheter and beyond the filter valve.Type: ApplicationFiled: May 3, 2018Publication date: September 6, 2018Applicant: Surefire Medical, Inc.Inventors: Bryan Pinchuk, James E.
