Patent number: 10384058Abstract: An apparatus for securing a sensor at the heart is formed based on a modified, branched, pacemaker lead to provide a heart anchor lead where two anchors are coupled to a single main lead rather than there being just a single anchor. Thus, the proposed heart anchor lead comprises a single main lead, a sensor included within the main lead, in which the sensor has a distal end and a proximal end, a first anchor coupled to the distal end of the sensor and extending outward from the distal end of the sensor, and a second anchor coupled to the proximal end of the sensor and extending outward from the proximal end of the sensor in a direction that forms an angle with the first anchor. The heart anchor lead can optionally also have a pacemaking function.Type: GrantFiled: June 14, 2018Date of Patent: August 20, 2019Assignee: Cardiaccs ASInventors: Erik Fosse, Jonas Tyssø

Patent number: 8565850Abstract: The invention relates to sweat activity measurement, e.g. for determining a physiological state of a subject, embodied by a method as well as a kit with an immittance measuring circuit and electrodes with contact electrolyte. Sweat activity is considered a transport phenomenon and can be defined as a flux, e.g. gram water per skin area per second. Prior art methods determining water absorbed per gram dry stratum corneum measures skin moisture and do not truly reflect sweat activity. A periodic signal with frequency of 60 Hz or lower is applied to reduce contribution from complex admittance of the skin, and skin conductance is measured as a degree of sweat activity. The contact electrolyte allows filling of sweat ducts with sweat from sweat glands, this may be characterized in that it does not substantially fill the sweat ducts when being positioned on the skin and/or in that it has a re-absorption time constant from the sweat ducts into the Epidermis of less than 15 min.Type: GrantFiled: July 1, 2008Date of Patent: October 22, 2013Assignee: Universitetet i OsloInventors: Ørjan Grøttem Martinsen, Sverre Jøran Grimnes, Erik Fosse

Patent number: 8545524Abstract: A method for interconnection of two tubular organs via an opening at one end of an end portion of a first organ and an aperture in a side wall of a second organ. The end portion is initially passed through a first passage of a first element until the end portion projects past an end edge of the element, whereupon the end portion is everted round the end edge. Gripping parts of a second element with a second passage are then inserted in the second organ via the aperture. Finally, the first element with the everted portion of the first organ is inserted in the second passage, whereby the gripping parts are influenced in such a manner that they come into engagement with the inside of an edge portion of the aperture. A device for implementation of the method.Type: GrantFiled: July 25, 2003Date of Patent: October 1, 2013Assignee: Anastomosis ASInventors: Sumit Roy, Erik Fosse, Ole Jakob Elle

Publication number: 20120289916Abstract: A method of providing a stoma with a removable connection for a receptacle includes securing an implant onto the stoma of a patient, wherein the implant has an axial interior section for fixation inside the body and an axial exterior section extending outwards from the body, a free end of the exterior section accommodates mounting of a detachable device, and a distal portion of the interior section includes an anchoring section, extending radially from the distal portion of the interior section. The anchoring section has an inner anchoring ring, an outer anchoring ring and at least one connection member configured and dimensioned for resiliently connecting the inner and outer anchoring rings in a manner to provide axial resilience and anchorage to the anchoring section such that the anchoring section is able to respond to movements and absorb the shear of the implant in relation to adjacent organs.Type: ApplicationFiled: July 20, 2012Publication date: November 15, 2012Applicant: OSTOMYCURE A/SInventors: Martin Johansson, Robert Axelsson, Anette Johnsson, Bjorn Edwin, Erik Fosse

Patent number: 8282568Abstract: A system and a method for estimating changes in cardiac pumping capacity in response to an intervention from data recorded by an accelerometer positioned on an outer surface of the heart. Interventions such as intravenous administration of nitroprusside, betablocker, epinephrine (adrenaline), or changes in the intravascular volume such as by fluid filling, are considered. It is shown that it is possible to directly correlate changes in cardiac pumping capacity to changes in parameters or graphical representation derived from signals characteristic to the acceleration an outer surface of the heart. In particular, it is shown how the effect of the interventions can be directly read from these parameters or graphical representations, and can thereby assist in decisions regarding the treatment of a cardiac surgery patient. The invention is preferably used in a post-surgery monitoring unit for surveillance of cardiac surgery patients.Type: GrantFiled: April 30, 2008Date of Patent: October 9, 2012Assignee: Bio-Medisinsk Innovasjon ASInventors: Ole Jakob Elle, Erik Fosse, Per Steinar Halvorsen

Publication number: 20110196324Abstract: A percutaneous implant serves for implantation into an animal or a human body. The implant is of the kind that has an axial interior section for fixation inside the body, an axial exterior section in communication with the interior section and extending outwards from the body with a free end. The free end of the exterior section serves for mounting of a detachable device. A distal end of the interior section opposite the exterior section is provided with an anchoring section, extending radially from the distal end of the interior section. The anchoring section includes an inner anchoring ring extending from or integral with the interior section, an outer anchoring ring, and at least one connection member configured and dimensioned for resiliently connecting the inner anchoring ring with the outer anchoring ring in a manner to provide axial resilience and anchorage to the anchoring section.Type: ApplicationFiled: April 18, 2011Publication date: August 11, 2011Inventors: Martin Johansson, Robert Axelsson, Anette Johnsson, Bjorn Edwin, Erik Fosse

Patent number: 7935096Abstract: A percutaneous implant serves for implantation into an animal or a human body. The implant is of the kind that has an anchoring section, extending radially from a distal end of an interior section. The anchoring section comprises an inner anchoring ring extending from or integral with the interior section, an outer anchoring ring, and at least one connection member for connecting the inner anchoring ring with the outer anchoring ring. Since a first connection point between a first end of the at least one connection member and the inner anchoring ring is angularly offset from a second connection point between a second end of the connection member and the outer anchoring ring, the anchoring section constitutes a resilient spring means, which adapts to the movements of the body. The implant is especially designed for use without externalization of the vessel to be brought into communication with the exterior.Type: GrantFiled: September 1, 2005Date of Patent: May 3, 2011Assignee: Ostomycure ASInventors: Martin Johansson, Robert Axelsson, Anette Johnsson, Bjorn Edwin, Erik Fosse

Publication number: 20110046488Abstract: The invention relates to a method and a post-operative care unit for analysing and quantifying an ultrasound tissue Doppler imaging (TDI) signal from a transducer fastened on the myocardium to obtain a parameter indicating regional cardiac ischaemia or correlates with global hypokinetic heart function. This has the advantage over manually operated probes that it can be automated and used continuously over long time. According to the method, a TDI signal trace corresponding to at least one of tissue velocity, strain or strain rate is extracted and correlated with an electrocardiogram to define subsections within a cardiac cycle in the extracted trace corresponding to the early systolic phase and the post-systolic phase. Then, a velocity, strain or strain rate is read in at least the post-systolic phase of the extracted trace, and a parameter which is a function of one of these readings and which indicates ischaemia or global hypokinetic function is generated.Type: ApplicationFiled: August 29, 2008Publication date: February 24, 2011Applicant: OSLO UNIVERSITETSSYKEHUS HFInventors: Ole Jakob Elle, Erik Fosse, Halfdan Ihlen, Andreas Espinoza, Lars Hoff
