Publication number: 20120226285Abstract: A bone filler delivery system comprises a longitudinal channel incorporates a perforated segment at least partially along, at or near its distal end. The channel can be sealed at its distal end so the filler material may be delivered only by the lumen and through the perforated segment. Optionally, said system comprises a permeable bag capable of being inserted into a bone while in collapsed configuration and then expanded when filled with bone voids filler. The mesh structure is designed to allow such permeable bag to expand to a predetermined size or shape under certain pressures and allows exudation of bone void filler through its walls. Extracting the permeable bag out of a treated body promotes flow of bone void filler through its pores into cancellous bone and/or cavity in the bone. The procedure promotes height restoration of the bone and introduces filler in a controlled manner.Type: ApplicationFiled: March 13, 2012Publication date: September 6, 2012Applicant: DePuy Spine, Inc.Inventors: Mordechay Beyar, Oren Globerman

Patent number: 8246629Abstract: A delivery device for a monomer may include an elongate container designed to enclose one or more ampoules containing the monomer. The elongate container may include: a connection at a first end of the elongate container for delivering the monomer to a mixing device, pre-filled with a polymer, for preparation of bone cement composition under vacuum; a cap at a second end of the elongate container; at least one air inlet aperture in a wall of the elongate container; and a manually actuatable element for opening the one or more ampoules. The manually actuatable element may include: a knob; a draw rod; and one or more spikes. The knob may be in threaded engagement with the draw rod. An end of the draw rod may extend past the one or more ampoules. Turning the knob may cause the one or more spikes to penetrate the one or more ampoules.Type: GrantFiled: March 31, 2003Date of Patent: August 21, 2012Assignee: Cemvac System ABInventor: Sören Jonsson

Patent number: 8246628Abstract: An apparatus and methods for delivery of reinforcing materials to a weakened or fractured bone is disclosed. An apparatus for delivering a reinforcing mixture to a bone including a tube having a proximal end, a distal end, and a longitudinal axis therebetween, wherein the tube has at least one inner lumen capable of allowing a bone reinforcing mixture to pass therethrough; a balloon engaging the tube wherein the balloon expands from a substantially deflated state to a substantially inflated state upon the bone reinforcing mixture entering the balloon; and at least one light guide extending through the tube into the balloon to guide a light into the balloon.Type: GrantFiled: September 3, 2010Date of Patent: August 21, 2012Assignee: IlluminOss Medical, Inc.Inventor: Robert A. Rabiner

Patent number: 8246627Abstract: A cavity creator including a tube with a lumen. A tip able to penetrate bone extends forward from the distal end of the tube. A blade is moveably attached to the outer tube proximal to the tip so as to move between retracted and extended states. The tube has a discharge port adjacent the blade. The tip is used to position the upper tube in bone. The blade is extended to form a cavity in the bone. Once the cavity is created filler material can be introduced into the cavity by flowing the material through the tube lumen.Type: GrantFiled: August 7, 2008Date of Patent: August 21, 2012Assignee: Stryker CorporationInventors: Ryan Vanleeuwen, Frank J. Cinder, Jared P. Coffeen

Patent number: 8241295Abstract: Apparatus and method to dispense PMMA bone cement including a temperature controller, a disposable cement cartridge and a means for extracting cement from the cement cartridge so that the temperature of the extracted cement is first cooled to discourage polymerization and to prolong working time, then warmed so as to control viscosity of the cement flowing into the desired bone repair location. A first embodiment includes a spiral cement cartridge along with a means for extracting cement therefrom. A second embodiment includes a linear disposable cement cartridge along with a means for extracting cement therefrom. A color matching mechanism identifies cement temperature and viscosity during dispensation. A manual cement dispensing method includes a calibrated hand crank mechanism for causing calibrated delivery of cement. An automatic cement dispensing method uses a stepper motor and computer programmed means for causing calibrated flow of cement.Type: GrantFiled: March 13, 2008Date of Patent: August 14, 2012Inventor: Erich W. Wolf, II

Publication number: 20120191102Abstract: A medicine injection device includes a medicine ejection unit having a fluid flow-in port for receiving liquid, and a pressure generation unit which includes a pressure generating chamber to generate pressure acting upon a working chamber of the medicine ejection unit through the liquid and which ejects medicine by moving a gasket based on the applied pressure. The pressure generation unit includes a pressure portion cylinder in the pressure generating chamber, a first pusher provided with a hollow gasket defining the inner volume of the pressure generating chamber and a second pusher which generates the pressure inside the pressure generating chamber by pressing a distal end head portion into the inside of the pressure generating chamber. The pressure portion cylinder and the first pusher are coupled through an engagement mechanism in which fixation and fixation release are possible at different pitches in the axial direction.Type: ApplicationFiled: March 29, 2012Publication date: July 26, 2012Applicant: Terumo Kabushiki KaishaInventors: Atsushi MATSUMOTO, Makoto Saruhashi

Patent number: 8226717Abstract: A percutaneous path is established into a selected bone having an interior volume occupied, at least in part, by a cancellous bone, e.g., a vertebral body. An expandable stent structure is introduced into the cancellous bone by deployment of a tool through the percutaneous path into the cancellous bone. The expandable stent structure is expanded within cancellous bone.Type: GrantFiled: September 27, 2006Date of Patent: July 24, 2012Assignee: Kyphon SarlInventors: Reynaldo A Osorio, Marialulu Follmer, Richard W Layne, Ryan P Boucher, Karen D Talmadge, Joseph J Basista
