Publication number: 20220218366Abstract: A clot removal system comprises a catheter, a vacuum source, and a controller. The catheter comprises a proximal end, a distal end, and controller operating parameters and defines a lumen configured to be filled with a liquid column having a proximal portion. The vacuum source is configured to supply vacuum. The controller is configured to carry out a control pattern of turning on and off the vacuum based upon the controller operating parameters and is configured to receive the controller operating parameters in an automatic response to the catheter being operatively connected to at least one of the vacuum source and the controller and, responsive to the connection, to carry out the control pattern to change a level of vacuum at the distal end of the catheter.Type: ApplicationFiled: January 26, 2022Publication date: July 14, 2022Inventors: Derek Dee Deville, Matthew A.

Patent number: 11382690Abstract: A method for operating a catheter provides a mechanical stiffener to a catheter shaft portion, the shaft comprising an inner sheath having a distal end and an outer surface and defining an access lumen extending distally to the distal end and an outer sheath having an inner surface surrounding the inner sheath distally to the distal end, defining an annulus between the outer and inner surfaces, the annulus having a connection at which vacuum applies to the annulus, and having a substantially constant outer diameter over the portion to the distal end. A tool is shaped and sized to pass through the access lumen and past the distal end. The portion is placed in an increased stiffened state by applying vacuum to create a stable base with at least a shaft segment within the anatomy that atraumatically resists reaction forces applied to the shaft by the tool.Type: GrantFiled: September 24, 2019Date of Patent: July 12, 2022Assignee: Syn Variflex, LLCInventors: Kevin W. Smith, Matthew A. Palmer, M. Sean McBrayer, Thomas O. Bales, Jr., Derek Dee Deville, Joe Abelleira

Patent number: 11376065Abstract: A controllable stiffness catheter includes a shaft comprising inner and outer sheaths, the sheaths each having proximal and distal ends. The outer surrounds the inner from the proximal to the distal end of the inner sheath, defining an annulus therebetween including a proximal portion having a vacuum connection to which vacuum is applied. The distal ends of the sheaths are longitudinally fixed to one another and sized for neurological vascular procedures. The outer has a substantially constant outer diameter over a distal portion of the annulus proximate to the distal ends. A vacuum device fluidically connects to the vacuum connection and is configured to apply vacuum thereto. Responsive to vacuum, annulus pressure lowers to draw the sheaths toward one another and stiffen the shaft over at least the distal portion to substantially and passively stiffen and maintain a current shape of the shaft over at least the distal portion.Type: GrantFiled: June 17, 2021Date of Patent: July 5, 2022Assignee: Syn Variflex, LLCInventors: Kevin W.
