Patent number: 9011897Abstract: This invention relates to compositions, methods, devices and kits relating to the infusion of a catheter lock solution into an indwelling catheter. Inventive compositions, methods, devices and kits aid in diminishing the effects of microbial infection in catheters and occlusion of the catheters. A lock solution provided by the invention includes citrate and a paraben. The solution preferably has a density suitable for retention of the solution in a catheter during the lock period. Another lock solution provided by the invention includes citrate, a paraben and a photo-oxidant, such as, for example, methylene blue.Type: GrantFiled: February 27, 2013Date of Patent: April 21, 2015Assignee: Ash Access Technology, Inc.Inventors: Stephen R. Ash, Janusz Steczko, Gary L. Swanson

Patent number: 6958049Abstract: This invention relates to an infusion device for a catheter lock solution, to a method of enhancing the patency of catheters in animals and to a catheter lock solution. The device includes a syringe (34) containing a lock solution comprising a citrate salt. The method for enhancing the patency of catheters includes infusing a lumen (14, 16) of an indwelling catheter (10) with a lock solution comprising a citrate salt. In one aspect of the invention, the catheter lock solution includes a citrate salt and a viscosifying agent. The lock solution is prepared to have sufficient viscosity and density to remain in the lumen for a desired amount of time.Type: GrantFiled: August 25, 1999Date of Patent: October 25, 2005Assignee: Ash Access Technology, Inc.Inventor: Stephen R.
