Patent number: 10744225Abstract: A silicone foam is described that is produced in-situ at a wound site, e.g. in a wound cavity, through a multi-component system, based on a physical foaming process, wherein the gas required to form the foam structure is provided through a blowing agent independently of the curing reaction of polyorganosiloxane components of the multi-component system. Therefore, the blowing agent is provided as a distinct entity of the multi-component system that is, in particular, not the result of any chemical reaction taking place in the multi-component system. A device for producing the foam and the corresponding negative pressure wound therapy kit are also described.Type: GrantFiled: August 24, 2016Date of Patent: August 18, 2020Assignee: MÖLNLYCKE HEALTH CARE ABInventors: Lars Lindgren, Dennis Hansson, Shiva Eibpoosh

Publication number: 20100178319Abstract: A topical dermal delivery device, such as a patch, for topical delivery of nitric oxide (NO) to treatment sites of mammals is disclosed. In an embodiment the patch has three layers; a backing with an activation window, a absorbent core as a reservoir and an NO permeable membrane with an adhesive layer towards the skin. The NO donor is applied into the device as a solution prior to application through the activation window. The window is closed after activation and the lid and backing is non-permeable for NO in order to increase the partial pressure of NO and thus the concentration of dissolved NO. The patch is fixated on the area to be treated with an adhesive layer that also assures sufficient contact throughout the treatment. The generated NO moves within the patch and can escape through the NO permeable membrane towards the area to be treated. Depending on therapy needed, the patch release curve differs and is chosen accordingly.Type: ApplicationFiled: March 27, 2007Publication date: July 15, 2010Inventors: Lars Lindgren, Linda Mårlind, Rikard Thorsen

Patent number: 6251394Abstract: A method and a system is described for reducing non-target levels of specific molecules intended for diagnostic and/or therapeutic applications to vertebrate hosts, wherein said molecules are administered to a vertebrate host and kept therein for a certain time in order to be concentrate to the target by being attached thereto. The molecules which are not attached to the target are removed from the blood circulation system or at least reduced to a lower concentration by passing the blood through an extra-corporeal device.Type: GrantFiled: October 12, 1993Date of Patent: June 26, 2001Assignee: Mitra Medical Technology ABInventors: Rune Nilsson, Lars Lindgren, Kristina Norrgren, Bengt Sandberg, Hans Olof Sjögren, Sven-Erik Strand

Patent number: 5957887Abstract: A medical catheter device that has a housing containing a needle and needle hub that are movable between a retracted position where the needle is safely within the protection of the housing and an extended position where the needle extends from the housing for insertion into a patient. After use, the needle can be moved to its retracted position to protect the user from inadvertent sticks from the needle. At the distal end of the catheter housing, there is a hub support having a through hole through which the needle extends when in its extended position. A flexible hollow trunk extends proximally from the through hole back into the housing and through which the needle passes. When the needle is withdrawn into its retracted position, the needle is physically caused to be moved off center so as to not realign with the through hole, however, the needle end remains encased within the flexible hollow trunk to prevent blood from entering the through hole into the interior of the housing.Type: GrantFiled: August 14, 1997Date of Patent: September 28, 1999Assignee: Becton Dickinson Infusion Therapy AktiebolagInventors: Roland J. Osterlind, Lars A. Lindgren, Hans A. Nilsson

Patent number: 5031675Abstract: A device for sealing a container intended to be connected to a recipient provided with a connector for supply of its contents to the recipient in such a way that the container can be applied to and removed from the recipient without leakage and is sealed after the removal. For this purpose an elastic body is included in the device, which contains a cavity with a thin bottom, which cavity is adapted to the connector and is inclined relative to the longitudinal axis of the body, so that the interior portion of the body is displaced radially time of application of the device to the connector and opens a channel between the body and the container wall for air supply to the container. The interior portion of the cavity is smaller than the exterior portion of the connector to enable the connector to open the sealing device by widening a normally closed hole or slit located at the bottom of the cavity.Type: GrantFiled: July 14, 1989Date of Patent: July 16, 1991Assignee: Rexinell ABInventor: Lars Lindgren
