Patent number: 9168354Abstract: A protective catheter tip has a generally tubular body portion defining an interior cavity. The proximal end of a urinary catheter is at least partially received within the protective tip, with the protective tip being retained on the urinary catheter without the need for a sleeve connecting the protective tip and the catheter. The protective tip may include a projection received within a draining hole or eye at the proximal end of the catheter to retain the protective tip on the catheter. The protective tip may instead include one or more projections that apply a frictional force to an outer surface of the catheter to retain the protective tip on the catheter. The protective tip may instead be retained on the catheter by a tether extending between the protective tip and a distal end of the catheter. The protective tip may also include two separate or separable pieces.Type: GrantFiled: March 14, 2013Date of Patent: October 27, 2015Assignee: Hollister IncorporatedInventors: David Hannon, Colm Mulkerrin, Michael Murray, Padraig O'Flynn, Martin McMenamin, Adam Foley
