Patent number: 10207057Abstract: A syringe includes a barrel and a rotatable element on the barrel, for example, at a proximal location along the length of the barrel. The rotatable element rotates at least partially around the barrel. When a handle is associated with the rotatable element, the barrel may rotate as the handle is held substantially stationary or the handle may be rotated while the barrel and any peripheral device secured thereto remain substantially stationary. When handles are associated with a rotatable element that may be removed from a barrel, a barrel that is disassembled from the rotatable element may be replaced with another barrel of the same or a different configuration. The barrel and plunger may be configured to cause the barrel to rotate as the plunger moves along the length of the barrel. Methods of using a syringe with a rotatable element on a barrel thereof are also disclosed.Type: GrantFiled: March 18, 2014Date of Patent: February 19, 2019Assignee: Control Medical Technology, LLCInventor: Shawn P.

Publication number: 20120071838Abstract: A rapid exchange aspiration catheter includes a distal portion with a round cross-sectional shape, taken transverse to a longitudinal axis of the catheter. A primary lumen through the catheter has a size and a shape, and extends through the catheter at a location that are optimized for aspiration. In particular, the size of the primary lumen is maximized relative to the outer diameter of the catheter by minimizing the thicknesses of interior walls of the catheter. Such optimization maximizes the rate at which fluid flows through the aspiration catheter without compromising the ability of the catheter to withstand negative pressure (i.e., a vacuum). The present invention also includes systems in which the catheter is used in conjunction with a guide catheter and a wire, systems in which the catheter is used in conjunction with an aspiration element, and methods of using the catheter.Type: ApplicationFiled: September 22, 2010Publication date: March 22, 2012Applicant: CONTROL MEDICAL TECHNOLOGY, LLCInventor: Shawn P.
