Patent number: 11779727Abstract: A urinary catheter assembly includes a urinary catheter having a proximal part with an insertion tip, a distal part and a tubular shaft extending between the insertion tip and the distal part. A package having at least a first compartment with an opening is provided to enclose the proximal part and at least a part of the tubular shaft therein in a curved or curled state during storage. A protective sleeve arrangement is arranged around the distal part of the urinary catheter, and a distal end of the protective sleeve arrangement is connected to the urinary catheter, at or in the vicinity of a distal end of the catheter. The protective sleeve arrangement includes at least two sleeves that are telescopically displaceable in relation to each other, and the protective sleeve arrangement is transformable between a retracted position and an extended position.Type: GrantFiled: October 26, 2021Date of Patent: October 10, 2023Assignee: DENTSPLY IH ABInventors: Karsten Eriksson, Michael Sandberg, Niklas Dahlberg, Benny Svendsen

Publication number: 20220001139Abstract: A medical device assembly comprises a medical device, such as a urinary catheter, comprising an insertable part and a non-insertable part. The insertable part comprises an elongate shaft provided with a hydrophilic coating or surface. The assembly further comprises a wetting fluid compartment arranged to encircle at least a part of the medical device, and preferably at least a part of the non-insertable part, and an aqueous fluid arranged in the wetting fluid compartment. At least one of the aqueous fluid and the hydrophilic coating or surface comprises at least one surfactant. The hydrophilic coating or surface is maintained essentially separated from the aqueous fluid, and arranged to become wetted by movement of the elongate shaft through the wetting fluid compartment.Type: ApplicationFiled: June 28, 2021Publication date: January 6, 2022Inventors: Karsten ERIKSSON, Michael SANDBERG, Åsa WESTLING, Frida ISELAU, Niklas DAHLBERG

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

Patent number: 10974025Abstract: A urinary catheter and a method of its manufacture are disclosed. The urinary catheter comprises a tubular shaft extending between an insertion end and a discharge end, the tubular shaft being formed of at least two materials having different properties. The materials are arranged substantially separated from each other in distinct zones, wherein at least one of the width and thickness of said zones varies over the length of the tubular shaft, to form two or more uniform sections of the tubular shaft having various relative amounts of said materials, and wherein at least one transition between two such uniform sections is formed by at least one transition section providing a gradual transition between the uniform sections. The catheter can e.g. be produced by intermittent extrusion.Type: GrantFiled: June 28, 2017Date of Patent: April 13, 2021Assignee: DENTSPLY IH ABInventors: Jan Utas, Niklas Dahlberg, Martin Lovmar

Publication number: 20200230356Abstract: A method for producing a urinary catheter comprises the steps: providing a tubular catheter shaft having an axially extending lumen therein; thermoforming an end of the tubular catheter shaft into a closed end; inserting said closed end of the tubular catheter shaft into an injection mold cavity; and injecting thermoplastic polymer material into the mold cavity to form a tip on the thermoformed end of the tubular catheter shaft. Hereby, a very effective method is obtained, forming securely attached tips. Alternatively, an end of the tubular catheter shaft with a non-closed opening may be inserted into the injection mold cavity; and thermoplastic polymer material be injected into the mold cavity to form a tip on the end of the tubular catheter shaft, whereby the injecting is controlled so that a limited amount of thermoplastic polymer enters into the lumen.Type: ApplicationFiled: January 21, 2020Publication date: July 23, 2020Inventors: Jan Utas, Niklas Dahlberg
