Publication number: 20090204120Abstract: The invention relates to a device for the application of bone cement, in particular in the field of vertebroplasty, comprising an application conduit (1) guiding the bone cement towards the application area and a flexible piston rod (2) longitudinally movable in the application conduit (1) and provided with a piston (3) arranged at the distal end of the rod (2), said piston being in contact with and providing a seal at the internal wall of the application conduit (1), with the piston rod (2) protruding proximally from said application conduit (1) and the application conduit (1), at least partially, being formed into one or several windings (5). A spirally or helically wound application conduit (1) results in the effective useful length of the application conduit (1) being relatively great with the overall dimensions of the application device on the other hand still being moderate.Type: ApplicationFiled: September 13, 2006Publication date: August 13, 2009Applicant: AMEDO GMBHInventors: Volker Trösken, Martin Deli, Jürgen Speder, Katja Gonschorek, Ronald Kontek, Marion Denk, Dietrich Grönemeyer

Publication number: 20090099666Abstract: The invention relates to the use of a spongy material for the production of an implant (10) designed to obstruct a cyst neck (3). As spongy material especially the polyvinyl alcohol Ivalon can be employed. The invention furthermore relates to a set of instruments for the introduction of such an implant (10) made of a spongy material into a cyst neck (3) with said set of instruments consisting of a puncture needle (5) for the insertion of a guide wire (6), a guide wire (6) the distal end of which can be introduced into the cyst neck (3), an implant needle (7) provided at its proximal end with a connection element, a feeding unit (8) that can be attached via the connection element to the implant needle (7), and the implant (10) proper which consists of a spongy material and can be introduced via said feeding unit (8) through the implant needle (7) into the cyst neck (3). The inventive set of instruments may in particular be used for the treatment of Baker's cysts.Type: ApplicationFiled: August 9, 2006Publication date: April 16, 2009Inventors: Markus Braun, Jurgen Speder, Martin Deli, Volker Trosken

Publication number: 20050079196Abstract: The invention concerns a medical implant in the form of at least an elongated filament. The latter is preformed so as to have a specific structure when it is set on the implantation site. Said filament is traversed in the longitudinal direction by at least a removable retaining element which, until its removal, prevents the filament from having said specific structure.Type: ApplicationFiled: November 12, 2002Publication date: April 14, 2005Inventors: Hans Henkes, Hermann Monstadt, Jurgen Speder, Ronald Kontek

Publication number: 20040138528Abstract: A surgical instrument is disclosed, preferably for the minimally invasive intervention in human or animal tissues comprising a, for example, needle-shaped base body (3) with at least one passage formed from a hollow fiber (2). The at least one hollow fiber (2) is surrounded by a matrix (5) of a fibre composite material. The use of hollow fiber (2) permits a simple production in particular of instruments with a number of passages. The use of more than one hollow fiber (2) within the base body (3) increases the application possibilities, for example, simultaneous monitoring and treatment of the tissue.Type: ApplicationFiled: August 18, 2003Publication date: July 15, 2004Inventors: Jorn Richter, Andreas Bracke, Dietrich H W Gronemeyer, Jurgen Speder, Manfred Weck, Stefan Fischer, Sven Carsten Lange, Benno Brocher, Florian Schmidt, Daniel E Spielberg

Patent number: 4785825Abstract: Safety biopsy forceps, in particular for infants, comprise operating forceps, a flexible shaft, a pulling element, as well as a head with cutting- and/or grasping elements, of which at least one element is moveable by means of the pulling element, provided with a head with cutting- and/or grasping element which is detachably fastened on the flexible shaft. The flexible shaft is detachably fastened to the operating forceps and the pulling element to the operating forceps. The pulling element is adjustable for the setting of the cutting- and/or grasping elements and the setting of the force of the cutting process and can also be locked in after the adjustment. The cutting- and/or grasping elements are provided at the joint with a recess which prevents tissue from becoming lodge during closing of the elements.Type: GrantFiled: February 4, 1988Date of Patent: November 22, 1988Assignee: Humboldt--Universitaet zu BerlinInventors: Paul Romaniuk, Jurgen Speder, Hans-Peter Dubel, Siegfried Muller
