Patent number: 8257310Abstract: A syringe for performing a medical procedure includes a pressure sensor, a volume sensor, and a compensation circuit. The volume sensor measures a volume of a flowable material that is dispensed from the syringe, the pressure sensor measures a pressure being applied to the flowable material, and the compensation circuit calculates a delivered volume of the flowable material by accounting for system compliance (expansion) as the pressure is increased. By compensating for system compliance in this manner, a syringe can be used in high pressure procedures while still providing accurately controllable material delivery.Type: GrantFiled: August 2, 2011Date of Patent: September 4, 2012Assignee: Kyphon SARLInventors: Brian W. Donovan, Andrea Y. Leung, Lisanne A. Eng, David P. Thompson, Robert B. Hubler, Stephanie A. Barnes, Thomas C. Arends, Keith Schubert, Paul C. Leonard, Paul F. Muller

Publication number: 20080140082Abstract: Devices and methods for performing a procedure within a sacrum are disclosed herein. In one variation, a method includes imaging a spine with a fluoroscopy device to provide a view of the sacrum. An anatomical landmark is identified based on the imaging, and a breach zone is defined based on the imaging. The anatomical landmark is used to identify an entry point and guide a medical device in a medial-to-lateral approach into a sacral ala region of the sacrum to perform a medical procedure within the sacral ala. In some embodiments, the anatomical landmark can be, for example, a pedicle, and in some embodiments, the anatomical landmark can be, for example, a V notch. In some embodiments, an entry point is identified using two anatomical landmarks. For example, the anatomical landmarks can be an S1 foramen of the side being accessed and a sacroiliac joint.Type: ApplicationFiled: July 16, 2007Publication date: June 12, 2008Inventors: Eren Erdem, Lisanne A. Eng, Christopher U. Phan, Meera Sankaran, Ed Asturias

Patent number: 7351211Abstract: A tissue separator assembly has an elongate tubular member and a tissue separator device located at a distal end of the elongate tubular member. An elongate coupler extends through the lumen of the elongate tubular member and has a distal coupler end. A tissue localization assembly has an elongate member and a localization device located at the distal end of the elongate member. The localization device may be movable from a first, radially-contracted state to a second, radially-expandable state. The distal coupler end of the elongate coupler and the proximal end of the elongate tubular member of the localization assembly are joinable to one another to permit docking of the tissue localization assembly to the tissue separator assembly. Methods of use of this device are also described.Type: GrantFiled: October 7, 2005Date of Patent: April 1, 2008Assignee: Artemis Medical, Inc.Inventors: Eric L. Buehlmann, Lisanne A. Eng, Christine P. Ventura, Robert J. Laird, Frank Ingle

Patent number: 6994677Abstract: A tissue localizing and separating assembly comprises a shaft, having a distal shaft portion, and a tissue separator device extending along the shaft. The tissue separator device has a distal separator part at the distal shaft portion movable between a retracted state, towards the distal shaft portion, and an outwardly extending, operational state, away from the distal shaft portion. A tissue localization assembly has a radially-expandable end. An elongate coupler may be used to dock the tissue localization assembly to the tissue separator device.Type: GrantFiled: February 25, 2003Date of Patent: February 7, 2006Assignee: Artemis Medical, Inc.Inventors: Eric L.

Patent number: 6056756Abstract: A tool for preparing a bone end for prosthetic joint replacement. The tool rests on a resected end of one bone of an articulating joint set, and includes a jack assembly for supporting an opposing bone of the set in flexion while the bone ends remain attached together by ligaments. The jack pivotally supports the opposing bone and raises it to the spacing of the intended prosthesis to allow the surgeon to balance soft tissue tension. This support allows the bone to rotate under the tension of the connecting ligaments, into natural alignment while a template carried by the jack assembly lies against the prepared end, so subsequent cuts are in correct rotational alignment and the bone enjoys a natural posture when the joint components are attached.Type: GrantFiled: August 11, 1998Date of Patent: May 2, 2000Assignee: Johnson & Johnson Professional, Inc.Inventors: Lisanne Eng, Dennis Colleran, John Slamin
