Patent number: 11135361Abstract: 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: GrantFiled: May 3, 2018Date of Patent: October 5, 2021Assignee: Surefire Medical, Inc.Inventors: Bryan Pinchuk, James E.

Patent number: 11006975Abstract: The present invention is a Distally Assembled Steerable Cannula (DASC), a robotically-manipulated device that can be deployed and extended within a patient's body by growing from its distal end, or can be used in non-medical applications. In some embodiments, growth occurs by sequentially assembling segments that interlock to form a rigid tube with a complex 3-D shape. The segments are individually transported through the growing cannula, and then assembled at the distal end. A segment can be wedge-shaped in profile, allowing adjustment of the local radius and plane of curvature of the cannula to be controlled by relative segment orientation.Type: GrantFiled: March 10, 2016Date of Patent: May 18, 2021Assignee: Southern Methodist UniversityInventors: Adam Cohen, Edmond Richer
