Publication number: 20240130785Abstract: A laser system may include a controller configured to direct a plurality of temporally spaced-apart electrical pulses to a device that optically pumps a lasing medium, and a lasing medium configured to output a quasi-continuous laser pulse in response to the optical pumping. The plurality of temporally spaced-apart electrical pulses may include (a) a first electrical pulse configured to excite the lasing medium to an energy level below a lasing threshold of the lasing medium, and (b) multiple second electrical pulses following the first electrical pulse. The quasi-continuous laser pulse is output in response to the multiple second electrical pulses.Type: ApplicationFiled: January 4, 2024Publication date: April 25, 2024Applicant: Boston Scientific Scimed, Inc.Inventors: Werner FALKENSTEIN, Michael SCHUBERT, Stephan DITTMAR, Anna BUTSCH, Thomas KREMSER

Patent number: 7048658Abstract: A device for converting a rotational movement into an axial movement includes driven planetary rollers (10) and a sliding body (5) that can be axially displaced by means of the planetary rollers (10). The planetary rollers (10) are fixed axially in a driven carrier (9), are rotationally mounted and are provided with grooves (11). The grooves (11) of these planetary rollers (10) engage in a thread-type groove of the sliding body (5). In the center of the carrier (9) a bearing body (7) is provided, which engages in the grooves (11). The grooves (11 and 12) have a mutually adapted gradient, and the planetary rollers (10) and the bearing body (7) engage with one another without slip. Also the carrier (9) and the bearing body (7) engage with one another without slip. The carrier (9) and the bearing body (7) are driven in a rotational relationship, which guarantees that no slip occurs between the planetary rollers (10) and the sliding body (5).Type: GrantFiled: July 18, 2001Date of Patent: May 23, 2006Assignee: Wittenstein Motion Control GmbHInventors: Michael Butsch, Martin Brehmer

Patent number: 6925901Abstract: A device for converting rotational movement into axial movement includes planetary rollers driven by a drive shaft projecting from a drive device and maintained peripherally at a same distance, in addition to a push body axially displaced by the planetary rollers. These planetary rollers are peripherally fixed on a support which is driven around the axis thereof, the rollers being rotationally mounted and provided with peripheral grooves or threaded grooves; the support is connected in a fixed manner to the drive shaft rotating around its axis; the planetary rollers engage in at least one thread-like groove of the push body that is displaced along the axis of the support by means of their peripheral grooves or threaded grooves.Type: GrantFiled: December 12, 2000Date of Patent: August 9, 2005Assignee: Wittenstein AGInventors: Michael Butsch, Jörg Henle

Patent number: 6893375Abstract: The invention relates to a planetary gear with little play that comprises, for one stage of reduction each, at least one sun wheel, an elastically deformable internal geared wheel, planet wheels that are rotatably received by a planetary carrier and that act on the one hand on the sun wheel and on the other hand on the internal geared wheel, thereby transmitting power, and a housing. The aim of the invention is to provide a planetary gear that is simple in design and reliable in operation. To this end, the elastically deformable internal geared wheel is configured as an outer wall zone of the housing.Type: GrantFiled: May 28, 2001Date of Patent: May 17, 2005Assignee: Alpha Getriebebau GmbHInventor: Michael Butsch

Publication number: 20040116218Abstract: The invention relates to a device for converting a rotational movement into an axial movement, comprising driven planetary rollers (10) and a sliding body (5) that can be axially displaced by means of the planetary rollers (10). The planetary rollers (10) are fixed axially in a driven carrier (9), are rotationally mounted and are provided with grooves (11). The grooves (11) of said planetary rollers (10) engage in a thread-type groove of the sliding body (5). In the centre of the carrier (9), a bearing body (7), which engages in the grooves (11), is provided. The aim of the invention is to construct said device in a simple manner and at the same time configure it to be devoid of slip.Type: ApplicationFiled: May 22, 2003Publication date: June 17, 2004Inventors: Michael Butsch, Martin Brehmer

Patent number: 6730087Abstract: A distraction device for moving apart a bone, present in one or more parts and possibly separated, so as to extend or bridge a bone fissure, comprising an intramedullary nail which can possibly be introduced into a medullary space of a bone and has at least two elements which can be axially displaced in relation to each other. To effect said displacement at least one working device is joined to the element and a movable retaining element which is supported on the element.Type: GrantFiled: March 2, 2001Date of Patent: May 4, 2004Inventor: Michael Butsch

Publication number: 20040023751Abstract: The invention relates to a planetary gear with little play that comprises, for one stage of reduction each, at least one sun wheel (4, 7), an elastically deformable internal geared wheel (11), wheels (6, 9) that are rotatably received by a planetary carrier (5, 8) and that act on the one hand on the sun wheel and on the other hand on the internal geared wheel (11), thereby transmitting power, and a housing. The aim of the invention is to provide a planetary gear that is simple in design and reliable in operation. To this end, the elastically deformable internal geared wheel is configured as an outer wall zone of the housing.Type: ApplicationFiled: November 25, 2002Publication date: February 5, 2004Inventor: Michael Butsch

Patent number: 6245075Abstract: The invention concerns a distraction device for moving apart two bone sections, in particular for extending bones or bridging a gap in a bone, the device comprising an intramedullary nail (1) which can be introduced into the medullary space of a bone and comprises two parts (2, 3) which can be moved axially and can each be secured to one of the two bone sections. The distraction device further comprises a drive unit (4) that drives a drive shaft (16), and a device for converting the rotational movement of the drive shaft (16) into a relative axial movement of the two parts (2, 3) of the intramedullary nail (1).Type: GrantFiled: December 9, 1999Date of Patent: June 12, 2001Assignee: Wittenstein Motion Control GmbHInventors: Augustin Betz, Michael Butsch

Patent number: 6186020Abstract: The invention concerns a device for the conversion of rotary into axial movement with planet rollers supported at an equal peripheral distance and driven by a drive shaft, and with a thrust body that is axially-displaceable through the planet rollers which are supported to be rotatable around their fixed axes in an axle-driven carrier and with drive groove via which the planet rollers, driven by their carrier, engage in at least one screw-type groove on the thrust body which is displaceable along the axis of the carrier; the device should be of simple construction and have as low a frictional loss arising from the movement conversion as possible. For this purpose, the carrier is fixed to the drive shaft rotating in its axle. There is no power transmission during movement conversion between the drive shaft and the carrier via the parts that are tooth-engaged in one another.Type: GrantFiled: April 7, 1998Date of Patent: February 13, 2001Assignee: Wittenstein GmbH & Co.Inventor: Michael Butsch

Patent number: 6131479Abstract: A device for converting rotary motion into axial motion, having planetary rollers which are driven from a stationary drive housing by a drive shaft. These planetary rollers are held circumferentially at the same distance apart by a rotatable cage. The planetary rollers engage a thrust element via drive grooves on both the planetary rollers and the thrust element. The drive grooves on the planetary rollers do not engage the drive grooves on the drive shaft which frees the planetary rollers from harmful double engagement. The drive shaft drives these rollers via a gear tooth region on the rollers so as to function reliably and durably with a compact construction. The thrust element which is hollow, is therefore, able to move with a free thrust, i.e. without an additional guide element guiding it along a thrust path. Finally the thrust element has a high bucking strength so that it can withstand relatively large axial pressure.Type: GrantFiled: November 25, 1998Date of Patent: October 17, 2000Assignee: Dewitta Spezialmaschinenfabrik Wittenstein GmbH & Co.
