Publication number: 20050010140Abstract: A shockwave or pressure-wave therapeutic apparatus is provided in which a therapy head is equipped with a shockwave source. The shockwave source is connected via a shock generator to a control means which controls the release frequency of shockwaves as a function of the pulse energy thereof in such a manner that higher pulse energies correlate with lower release frequencies of the shockwaves and vice versa.Type: ApplicationFiled: May 28, 2004Publication date: January 13, 2005Applicant: Dornier MedTech Systems GmbHInventor: Bernd Forssmann

Patent number: 4809682Abstract: An underwater electrodes assembly for contactless lithotripsy is suggested wherein two electrodes have tips facing each other across a narrow gap and at least one, preferably both, electrodes are surrounded by sleeves or rings made of a dielectric material, such as a thermoplastic.Type: GrantFiled: December 10, 1986Date of Patent: March 7, 1989Assignee: Dornier Medizintechnik GmbHInventors: Bernd Forssmann, Harald Eizenhoefer
-
Patent number: 4745920Abstract: An instrument for therapeutic shock waves in which the shock waves are triggered in response to the patient's heartbeat cycle or to the patient's breathing cycle or both.Type: GrantFiled: August 10, 1987Date of Patent: May 24, 1988Assignee: Dornier System GmbHInventors: Bernd Forssmann, Wolfgang Hepp, Klaus Ackern, Christian Chaussy

Patent number: 4705026Abstract: A concrement in a human body is located by an X-ray system establishing an axis through the concrement; ultrasonic equipment determines a depth coordinate value for the concrement on that axis, and a shock gyrator and focusing system is placed on that established axis for obtaining the comminution. A rest is provided for placing the body in the action zone, and for establishing a second axis in a coordinate system; the third axis is perpendicular to the latter and defines locally the direction of position change for the various types of equipment needed to carry out the aforementioned program.Type: GrantFiled: May 8, 1985Date of Patent: November 10, 1987Assignee: Dornier System GmbHInventors: Christian Chaussy, Wolfgang Hepp, Dick van Rijn, Bernd Forssmann
-
Patent number: 4685461Abstract: A trigger instrument for therapeutic shock waves, in particular for comminuting kidney stones, in which the shock waves are triggered by the R pip of the EKG or by a preselected time-delay thereafter.Type: GrantFiled: August 11, 1986Date of Patent: August 11, 1987Assignee: Dornier System GmbHInventors: Bernd Forssmann, Wolfgang Hepp, Klaus Ackern, Christian Chaussy
-
Patent number: 4655205Abstract: A template member made of shock wave impermeable material such as air filled foam is affixed to the body of a living being (e.g. a human patient) leaving however an opening through which shock waves from a shock wave generator can pass so that a concrement in the body will be comminuted while the template member shields sensitive organs against parasitic ultrasonic radiation.Type: GrantFiled: May 8, 1985Date of Patent: April 7, 1987Assignee: Dornier System GmbHInventors: Wolfgang Hepp, Bernd Forssmann, Walter Brendel, Christian Chaussy
-
Patent number: 4622969Abstract: An apparatus for the comminution of concrements such as kidney stones, and including a source of shock waves partially surrounded by an ellipsoidal reflector, is improved in that the open end of the reflector for sound wave transmission is additionally defined by a plurality of sound attentuating rings diminishing in internal diameter with distance from the source of shock waves; additional features provide for an overall increase in specific weight of these rings; the transmission of x-rays through the equipment is separately controlled.Type: GrantFiled: June 6, 1984Date of Patent: November 18, 1986Assignee: Dornier System GmbHInventors: Bernd Forssmann, Christian Chaussy
-
Patent number: 4552348Abstract: A couch to securely support and keep in place a completely or partially anesthesized patient in a compression-free and strain-free manner, for instance for contact-less comminution of renal calculi, where the patient by means of strongly mutually inclining and individually adjustable rest surfaces (11, 25, 26) in the shoulder area and at the legs is moved into a back position with a slightly raised upper body and angled legs, with a clear back and rectal area, and with placement of the lower arms next to the head so as to assume a stable hollow-back position.Type: GrantFiled: January 5, 1983Date of Patent: November 12, 1985Assignee: Dornier System GmbHInventors: Bernd Forssmann, Hans-Heinrich Gerth, Hendrik Zech, Christian Chaussy
