Patent number: 9066732Abstract: Methods and apparatus for surgical treatment of vertebrae, comprising a brush-like tamp component for addressing cancellous bone and a slider component that may be distally advanced over the brush-like tamp component while both are (preferably) aligned within a working cannula providing access to a drill channel within the vertebrae. Distal advancement of the slider creates a combination of it and the brush-like component. A handle provides mechanical advantage.Type: GrantFiled: September 15, 2008Date of Patent: June 30, 2015Assignee: Crosstrees Medical, Inc.Inventors: Richard W. Layne, Lawrence R. Jones, David T.

Patent number: 8961553Abstract: An extractable device is used to insert a flowable material into a vertebral body. The device comprises a filling member and a flowable material. The filling member is made of a flexible wall which includes a holding portion and an injection port via which the flowable material is injected into the holding portion after insertion into the vertebral body. The holding portion is provided with an opening which is releasably closed by a closure device so as to make the opening substantially resistant to the passage of material there through. Once the flowable material in the holding portion increases in viscosity, the closure device is released, thereby enabling the filling member to be extracted from the vertebral body so as to leave only the material in the vertebral body. The flowable material should be a material capable of setting to a hardened condition.Type: GrantFiled: September 15, 2008Date of Patent: February 24, 2015Assignee: Crosstrees Medical, Inc.Inventors: Dan R. Hollowell, Richard W. Layne, Jason C. Morton

Patent number: 8454620Abstract: An elongated shaft is sized and configured to establish an access path to bone having an interior volume occupied, at least in part, by cancellous bone. The elongated shaft includes a generally closed distal end portion and a side opening spaced from the closed distal end. A first tool is sized and configured to be selectively inserted into the shaft and selectively removed from the shaft. The tool includes a region that, when the first tool is inserted into the shaft, is capable of being aligned with and advanced through the side opening to project outside the side opening and contact cancellous bone. A second tool is sized and configured, upon removal of the first tool from the shaft, to introduce into the shaft a bone filling material for discharge through the side opening into the cancellous bone contacted by the first tool.Type: GrantFiled: December 7, 2010Date of Patent: June 4, 2013Assignee: Kyphon SarlInventors: Christopher R.

Patent number: 8317865Abstract: 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 mesh structure is introduced into the cancellous bone by deployment of a tool through the percutaneous path into the cancellous bone. The expandable mesh structure is expanded within cancellous bone by conveying a material into the mesh structure. Expansion of the mesh structure can, e.g., compact cancellous bone, and/or form a cavity in cancellous bone, and/or move fractured cortical bone.Type: GrantFiled: September 27, 2006Date of Patent: November 27, 2012Assignee: Kyphon SarlInventors: Reynaldo A Osorio, Marialulu Follmer, Richard W Layne, Ryan P Boucher, Karen D Talmadge, Joseph J Basista

Patent number: 8092480Abstract: This invention relates to devices, such as cannulas or needles, which are used for inserting expandable structures, such as medical balloons, into interior regions of a human or animal body, as well as methods for their use. In various embodiments, insertion devices described herein are capable of flaring at their tip to ease insertion and removal of expandable structures and reduce the risk of damaging such expandable structures during their insertion, inflation and removal. In other embodiments, insertion devices described herein are capable of directionally guiding and/or inhibiting expansion of an expandable structure within an interior region of an animal or human body to create optimally placed cavities for repair, augmentation and/or treatment of fractured and/or diseased bone.Type: GrantFiled: April 6, 2001Date of Patent: January 10, 2012Assignee: Kyphon SARLInventors: Richard W. Layne, Robert M. Scribner, Christopher R Ralph

Publication number: 20110288522Abstract: A medical implant device includes a shaft, an expandable member coupled to the distal end portion of the shaft, a sleeve and a detachment mechanism. The expandable member is configured to move between a collapsed configuration and an expanded configuration, and can be used to deliver a medicament, a therapeutic substance and/or a structural member into the body. The sleeve is coupled to the distal end portion of the shaft, and is configured to move relative to the shaft between a first position and a second position. The sleeve is configured to be disposed about the expandable member when in the first position and disposed apart from the expandable member when in the second position. The detachment mechanism is coupled to the distal end portion of the shaft, and is configured to detach the expandable member from the shaft when the sleeve is in the second position.Type: ApplicationFiled: December 17, 2010Publication date: November 24, 2011Applicant: Crosstrees Medical, Inc.Inventors: Dan R.

Patent number: 7967827Abstract: A percutaneous path is created into a bone having an interior volume occupied, at least in part, by a cancellous bone, e.g., a vertebral body. An expandable structure is introduced into the cancellous bone by deployment of a tool through the percutaneous path into the cancellous bone. The expandable structure is expanded and the tool withdrawn, leaving the expandable structure expanded inside the cancellous bone. Expansion of the expandable structure within cancellous bone can, e.g., compact cancellous bone, and/or create a cavity in cancellous bone, and/or move fractured cortical bone.Type: GrantFiled: September 27, 2006Date of Patent: June 28, 2011Assignee: Kyphon SARLInventors: Reynaldo A Osorio, Marialulu Follmer, Richard W Layne, Ryan P Boucher, Karen D Talmadge, Joseph J Basista, Mark A Reiley, Arie Scholten, Robert M Scribner

Publication number: 20080140079Abstract: A first tool establishes a percutaneous path into the vertebral body having an interior volume occupied, at least in part, by cancellous bone. The vertebral body has at least one cortical plate that is depressed due to fracture. A source of bone filling material has a viscosity that resists extravazation into cancellous bone, and a second tool conveys the bone filling material through the percutaneous path to move the fractured cortical plate toward a desired anatomic position. A third tool can be provided that is sized and configured for introduction through the percutaneous path and including an operative element that conditions cancellous bone for the introduction of the bone filling material.Type: ApplicationFiled: October 29, 2007Publication date: June 12, 2008Inventors: Revnaldo A.
