Patent number: 10702672Abstract: A multi-lumen catheter can be used to measure pressure at multiple locations within the vasculature. The multi-lumen catheter can include multiple segments, such as a proximal portion, an intermediate portion, and a distal portion. A segment of a multi-lumen catheter may differ from another segment of the same multi-lumen catheter in radiodensity, hardness, and/or some other characteristic. Some multi-lumen catheters are designed to permit measurements of pressure in different lumens.Type: GrantFiled: February 25, 2016Date of Patent: July 7, 2020Assignee: Merit Medical Systems, Inc.Inventors: Fred Lampropoulos, Nicholas Accisano, III, Jim Mottola

Publication number: 20180117288Abstract: The present disclosure relates to a drainage catheter and methods of use for providing improved catheterization procedures, such as during a percutaneous nephrostomy. The drainage catheter includes a body comprising a first tube segment and a second tube segment connected to one another at a curved end portion to form a continuous body structure. An inner surface of the curved end portion includes one or more drainage openings extending therethrough, with an outer surface of the curved end portion free of drainage openings to minimize potential clogging. The openings are in communication with a lumen that extends through the drainage catheter to provide a pathway for removing fluid from the kidney. The drainage catheter is inserted into the kidney via a first insertion site and exits via a second insertion site to minimize the potential for accidental removal of the catheter.Type: ApplicationFiled: November 2, 2017Publication date: May 3, 2018Inventors: Richard Lindsay, Denise Hallisey, Nicholas Accisano, III, David Butts, F.

Publication number: 20070185446Abstract: The present invention is directed to a dilator having a stiffened shaft for use as part of an introducer sheath assembly. The dilator includes a stiffener tube and a tip of the dilator which extends distally to the dilator stiffener tube. The transition between the stiffener tube and the tip of the dilator is positioned such that when the dilator is positioned within the catheter sheath, the transition is also positioned within the catheter sheath. By positioning the transition between the stiffener tube of the dilator and the tip of the dilator inside the catheter sheath, the catheter sheath can provide strain relief subsequent to lateral movement of the tip of the dilator in a manner that can prevent kinking of the dilator tip at the transition between the stiffener tip and the tip of the dilator.Type: ApplicationFiled: February 6, 2006Publication date: August 9, 2007Inventor: Nicholas Accisano
