Patent number: 9333331Abstract: A transcutaneous access port to a user has a coupling member destined to be anchored in a bone of the user. A first valve system is removably connectable to the coupling member and a second valve system is removably connected to the first valve system. An internal conduit is connected at its proximal end to the access port and at its distal end to a vascular structure of the user. An external conduit is connected to the access port and to an extracorporeal device. A traversing cavity is formed in the bone at an implantation site of the user, passing the internal conduit. The internal conduit is routed through the traversing cavity to connect its distal end to the vascular structure of the user. The coupling member is anchored to the bone at the implantation site. The proximal end of the internal conduit is connected to the access port.Type: GrantFiled: November 8, 2011Date of Patent: May 10, 2016Assignee: Cendres+Metaux SAInventors: Daniel Schutz, Jean-Marc Guenat, Adrian Auderset, Rudolf Hausler, Felix Frey, Anja Kruse, Andreas Arnold, Christof Stieger, Marco Domenico Caversaccio

Patent number: 8926591Abstract: A transcutaneous implantable access port for removal and/or return of fluids of a patient comprises a fixation unit adapted to be fixed to a bone of the patient; a valve unit comprising a sealing membrane at its distal end and one or more chambers; an internal conduit fluidly connectable to vascular structure of the patient and releasably connectable to the valve unit to establish fluidic communication between the internal conduit and said one or more chambers; and an extracorporeal connecting member having an end portion. The extracorporeal connecting member is connectable to the distal end of the valve unit, opening and closing a fluidic passage between the connecting member and said one or several chambers when the connecting member is respectively connected to the access port and withdrawn therefrom. The access port can be used for high volume removal and/or return of blood or other fluids from the patient.Type: GrantFiled: February 21, 2012Date of Patent: January 6, 2015Assignee: Cendres + Metaux SAInventors: Daniel Schutz, Jean-Marc Guenat, Adrian Auderset, Christof Stieger, Felix Frey, Rudolf Hausler

Patent number: 8845573Abstract: Implantable access device for removal and/or return of fluids to a patient, comprising a casing attached to an internal conduit to be connected with a lumen of the patient; a connector attached at the casing and connected to an external conduit, and arranged for attachment of an extracorporeal lumen to the device; and an actuator unit within the casing to selectively allow or block the fluid communication between the internal conduit and the external conduit; the device further comprising a fixation unit integrated in or attached at the casing arranged for fixation of the device to a bone of the patient; wherein the fixation unit extends axially along the longitudinal axis of the device. The disclosed access device can be used for high volume removal and/or return of blood or other fluids from the patient.Type: GrantFiled: August 19, 2010Date of Patent: September 30, 2014Assignee: Universitaet BernInventors: Rudolf Häusler, Felix Frey, Christof Stieger, Andreas Arnold, Stefan Farese, Dominik Uehlinger

Patent number: 8602964Abstract: An electromechanical actuator (100) suitable, for example, in hearing aid applications is disclosed. Certain embodiments of the actuator comprise a hermetic titanium housing (1), a mechanical output structure (110) emulating the long process of incus (8), and means for efficiently generating movement in the audible frequency range. The electromechanical actuator (100) may be configured to be coupled to the inner ear fluids via a conventional stapes prosthesis. The implantable actuator (100), which may be considered to be operably equivalent to a loudspeaker of a conventional hearing aid, may bypass the outer and the middle ear in order to directly drive the inner ear fluids. As such, embodiments of the electromechanical actuator of the present invention may be used to remedy any source of conductive hearing loss.Type: GrantFiled: November 30, 2005Date of Patent: December 10, 2013Assignee: Cochlear LimitedInventors: Hans Bernhard, Joel Fontannaz, Christian Peclat, Markus Haller, Karen Cauwels, Ben Kloeck, Karel Huybrechts, Christof Stieger, Rudolph Hausler, Thomas Kaiser
