Patent number: 11877762Abstract: A retrieval device can include inwardly facing protruding features that facilitate engagement and capture of a thrombus or other mass from a body lumen of a patient. The protruding features can deploy from a frame of the retrieval device to extend radially inwardly toward an opposing side of the frame. When deployed into a thrombus, the protruding features engage and urge the thrombus as the retrieval device moves to facilitate capture.Type: GrantFiled: October 30, 2020Date of Patent: January 23, 2024Assignee: REFLOW MEDICAL, INC.Inventors: John Fulkerson, Isa Rizk, Jihad Ali Mustapha, Teodoro S. Jimenez, Jr., Patrick Lo

Publication number: 20230248558Abstract: Delivery systems for expandable elements, such as stents or scaffolds having spikes, flails, or other protruding features for penetrating target tissue and/or delivering drugs within a human patient are described along with associated methods for using such systems. The delivery systems can be provided with a stent that is positioned over an inflatable balloon for expansion and delivery of the stent to a target delivery location. By positioning the stent over and about the inflatable balloon, the stent is ready to be expanded by the balloon immediately upon unsheathing with respect to the outer shaft. Additionally or alternatively, a stent can be positioned in an axially offset arrangement with respect to a balloon to reduce the need for space required by overlapping components.Type: ApplicationFiled: April 14, 2023Publication date: August 10, 2023Inventors: Teodoro S. Jimenez, Jr., Patrick Lo, John Fulkerson, Isa Rizk, Francisco Aguayo, Jihad Ali Mustapha, Gary Ansel

Publication number: 20180085648Abstract: One embodiment of an extendable and retractable tennis racquet contains a stringed area 01, throat 02, and shank 03 as one integral member. The handle is comprised of a shank inside of a hollow handle 05. A spring or flexible means 07 connects the shank to the hollow handle. When the racquet is swung, the centrifugal force generated pulls on the head assembly. The shank slides outward telescopically, thereby increasing the length of the racquet. At the end of the racquet swing, the restoring force of the spring overcomes the diminishing centrifugal force, which pulls the shank back to its retracted position. Other embodiments are described and shown.Type: ApplicationFiled: September 24, 2016Publication date: March 29, 2018Inventors: Nicholas Lo, Patrick Lo
