Publication number: 20210146109Abstract: A sheath for producing a fully sealed access to the interior of a vessel of an animal or human body comprises a base sheath having a tubular body defining a pass-through channel. The base sheath is adapted to be inserted into the vessel through a vessel aperture. A wall of the tubular body of the base sheath has a through channel. This channel extends in the wall from the distal end towards the proximal end. The channel can be present separately from the pass-through channel of the base sheath or can form a sideways extension of the pass-through channel, at least at the distal end. Such through channel is adapted to conduct blood from the vessel to the proximal end of the sheath when the sheath has been inserted into a vessel.Type: ApplicationFiled: December 1, 2020Publication date: May 20, 2021Inventors: Thorsten Siess, Christoph Nix, Frank Kirchhoff, Patrick Hunziker

Publication number: 20190326017Abstract: Apparatus and methods for calculating cardiac output (CO) of a living subject using applanation tonometry measurements. In one embodiment, the apparatus and methods build a nonlinear mathematical model to correlate physiologic source data vectors to target CO values. The source data vectors include one or more measurable or derivable parameters such as: systolic and diastolic pressure, pulse pressure, beat-to-beat interval, mean arterial pressure, maximal slope of the pressure rise during systole, the area under systolic part of the pulse pressure wave, gender (male or female), age, height and weight. The target CO values are acquired using various methods, across a plurality of individuals. Multidimensional nonlinear optimization is then used to find a mathematical model which transforms the source data to the target CO data. The model is then applied to an individual by acquiring physiologic data for the individual and applying the model to the collected data.Type: ApplicationFiled: April 23, 2018Publication date: October 24, 2019Inventors: Oliver Goedje, Matthias Bohn, Patrick Hunziker, Oleksii Morozov, Felix Friedrich

Patent number: 5910111Abstract: According to the invention, a method to process heart motion image data into a portable display medium is provided. An image sequence of heart motion is provided. Image sequences are incorporated in angularly multiplexed holograms so that the parallax, i.e. the relative position of observer and holographic medium, encodes heart motion. This way, a change in the viewing angle of the printed hologram leads to the perception of the complete heart cycle. Using this technique, it is possible to incorporate a complete temporal image sequence of the beating human heart to a single printable image which can be used for display, storage, documentation and reporting.Type: GrantFiled: September 30, 1997Date of Patent: June 8, 1999Inventor: Patrick Hunziker
