Publication number: 20210162172Abstract: A urinary catheter is disclosed, comprising a tubular shaft extending between an insertable end and a discharge end, and a tip fixedly connected to said insertable end of the tubular shaft. The tip has an outer diameter which at all places is equal to or lower than the outer diameter of the tubular shaft, and is very soft, so that the hardness of the tip is equal to or lower than 60 micro Shore A. It has been found that such a soft tip provides a catheter which is easier to insert into the urethra, in particular in urethras providing various types of obstacles. A corresponding method of manufacturing is also disclosed.Type: ApplicationFiled: January 14, 2021Publication date: June 3, 2021Inventors: Martin Nyman, Niklas Dahlberg

Publication number: 20140180261Abstract: A method for producing a medical device comprising the steps of: providing a tubular substrate, said tubular substrate enclosing an internal lumen and being provided with at least one recess in the outer surface, wherein said recess does not form a through going hole into the internal lumen; treating the outer surface of said tubular substrate, preferably by means of surface modification and/or by coating; and forming, after said treating of the outer surface, an opening within said at least one recess to form an access opening to said internal lumen.Type: ApplicationFiled: December 17, 2013Publication date: June 26, 2014Applicant: DENTSPLY INTERNATIONAL INC.Inventors: Martin NYMAN, Jan UTAS, Niklas DAHLBERG, Axel ENGSTRÖM

Patent number: 8747882Abstract: A use in a medical device of at least one salt of organic acid(s), and preferably a benzoate or a sorbate, as an antimicrobial agent is disclosed, and in particular for the manufacturing of an antimicrobial coating for a medical device, e.g., hydrophyllic urinary catheters, for the prevention of bacterial infection. The pH of the hydrophilic coating may be controlled to be in the range 4.0-8.0, preferably in the range 5.0-6.0, and preferably to be below 7.0. The pH of the hydrophilic coating could be controlled by means of a pH buffer, and preferably a citrate or phosphate buffer. A salt of organic acid in combination with a pH buffer has proven surprisingly efficient for inhibition of bacterial growth, and for prevention of bacterial infections.Type: GrantFiled: April 20, 2006Date of Patent: June 10, 2014Assignee: Astra Tech ABInventors: Jan Utas, Andrea Schmid, Agneta Nordholm, Martin Nyman

Patent number: 8127922Abstract: A catheter assembly (110, 210) comprising a catheter (130, 230) and a receptacle (120, 220) is disclosed. The receptacle is arranged to accommodate at least part of said catheter and having at least one opening (123) for withdrawal of said catheter. Further, the receptacle is provided with an antimicrobial compound (301) at least in the vicinity of the opening and at least on the outer surface of the receptacle, said antimicrobial compound inhibiting microbes from being transferred to said catheter while being withdrawn through said at least one opening.Type: GrantFiled: October 3, 2008Date of Patent: March 6, 2012Assignee: Astra Tech ABInventors: Agneta Nordholm, Martin Nyman, Daniel Holm

Publication number: 20100086580Abstract: There is disclosed a medical device, such as a urinary catheter, comprising a substrate material, a hydrophilic surface coating, e.g. comprising polyvinylpyrrolidone (PVP), arranged on at least a part of the surface of said substrate material, and an antibacterial layer comprising oligodynamic metal arranged between the substrate material and the hydrophilic surface coating. Further, the hydrophilic surface coating has a thickness large enough to provide a controlled release of oligodynamic metal ions through the hydrophilic surface coating, such as a thickness when dry that exceeds 3 ?m. Hereby, the variation in the release of the oligodynamic metal ions is significantly reduced, enabling an improved control of the release. A corresponding method is also disclosed.Type: ApplicationFiled: October 9, 2009Publication date: April 8, 2010Inventors: Martin Nyman, Agneta Nordholm, Eva-Helena Westman

Publication number: 20060240069Abstract: A use in a medical device of at least one salt of organic acid(s), and preferably a benzoate or a sorbate, as an antimicrobial agent is disclosed, and in particular for the manufacturing of an antimicrobial coating for a medical device for the prevention of bacterial infection. This is very useful in medical devices having a hydrophilic coating, such hydrophilic urinary catheters. It is further preferred that the pH of the hydrophilic coating is controlled to be in the range 4.0-8.0, and preferably in the range 5.0-6.0. It is also preferred that the pH of the hydrophilic coating is controlled to be below 7.0. The pH of the hydrophilic coating could be controlled by means of a pH buffer, and preferably a citrate or phosphate buffer. Specifically, the provision of the salt of organic acid in combination with a pH buffer has proven surprisingly efficient for inhibition of bacterial growth, and for prevention of bacterial infections.Type: ApplicationFiled: April 20, 2006Publication date: October 26, 2006Applicant: Astra Tech ABInventors: Jan Utas, Andrea Schmid, Agneta Nordholm, Martin Nyman
