  • Patent number: 10384058
    Abstract: 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.

  • Patent number: 9425333
    Abstract: A device including a surface layer of a selected material in a predetermined pattern on a substrate surface. A groove or ridge arranged in the substrate surface includes a bottom or top face, respectively, and at least one side face sloping relative to the bottom or top face. The surface layer is deposited on a part of the substrate including the groove or ridge by vacuum chamber sputtering the selected material from a sputtering source while moving the substrate past the sputtering source in a direction substantially perpendicular to a sputtering main lobe direction and with a normal to the substrate surface substantially in a predefined angle with the main lobe direction. By uniformly etching away surface layer material deposited on the substrate by the sputtering until freeing a substantial part of the side face, the predetermined pattern becomes defined substantially by the bottom face or the top face.

  • Patent number: 8565850
    Abstract: 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.

  • Patent number: 8545524
    Abstract: 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.

  • Patent number: 8282568
    Abstract: 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.

  • Publication number: 20120012170
    Abstract: A silicon crystal wafer or chip, and a method for processing a substantially pure or semiconductor level doped silicon crystal wafer or chip for adapting the wafer or chip for laser beam ablation of an electrically insulating surface layer carried on the wafer or chip. A layer of amorphous silicon of a thickness substantially larger than the thickness of the naturally obtained oxide layer, the amorphous silicon being a substantially pure or semiconductor level doped grade amorphous silicon, is produced on top of a substantially clean surface of the silicon crystal wafer or chip. A layer of the electrically insulating surface layer being substantially transparent to an optical wavelength of a laser beam that is extensively absorbed in the layer of amorphous silicon, is produced on the layer of amorphous silicon.

  • Patent number: 7935096
    Abstract: 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.

  • Publication number: 20110046488
    Abstract: 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.
