Patent number: 9924987Abstract: An orthopedic bone plate constructed from shape memory material provides the ability to move from an open shape to a compressed shape and create compression on two bones or bone fragments to encourage healing. The plate may be any number of shapes, with two or more screws anchoring the plate to bone. The plate is affixed to bone in a sequence of steps that involve first placing the plate on an insertion tool, attaching drill guide tubes, placing the plate over bone, drill holes in bone, and then attaching the plate to the bone via screws. The insertion tool can then be removed at the surgeon's convenience allowing compression on the two bones.Type: GrantFiled: July 7, 2016Date of Patent: March 27, 2018Assignee: BioMedical Enterprises, Inc.Inventor: Daniel F. Cheney

Patent number: 9924988Abstract: A method for locating a material having thermoplastic properties in pores of bone tissue includes providing a pin having the material having thermoplastic properties and a core, wherein the material having thermoplastic properties is arranged on the circumferential surface of the core constituting an outer region of the pin. An opening is provided in the bone tissue, and the pin is positioned at least partly in the opening. The outer region of the pin is then impinged with mechanical vibration energy for a time sufficient for liquefying at least part of the material having thermoplastic properties, and, in a liquefied state, pressing it into the pores of the bone tissue surrounding the opening. The vibration energy is stopped for a time sufficient for re-solidification of the liquefied material, and then the core is removed.Type: GrantFiled: March 20, 2017Date of Patent: March 27, 2018Assignee: WOODWELDING AGInventors: Marcel Aeschlimann, Laurent Torriani, Antonino Lanci, Jörg Mayer

Patent number: 9924990Abstract: Apparatus and methods for securing a bone implant are provided. The implant may be an expandable implant. The implant may be a non-expandable implant. The implant may be for repairing a bone fracture. The implant may be secured to a bone by anchors. The implant may include anchor receiving features. The anchor receiving features may be configured to direct an anchor into cortical bone. The anchor receiving features may be configured to receive an anchor driven through cortical bone. The implant may include bone engaging members configured to engage cancellous bone. An implant may include different profiles. The different profiles may be configured to secure the implant. The profiles may be configured to support the bone. The implant may have different flexing properties configured to position the implant in the bone. The implant may be positioned to receive an anchor driven through an outside of the bone.Type: GrantFiled: September 22, 2014Date of Patent: March 27, 2018Assignee: Conventus Orthopaedics, Inc.Inventors: Todd A. Krinke, Steve D. Kruse, Michael P. Brenzel, Paul Hindrichs, Alex A. Peterson

Patent number: 9924992Abstract: An instrument and method for tissue thermotherapy including an inductive heating means to generate a vapor phase media that is used for interstitial, intraluminal, intracavity or topical tissue treatment. In one method, the vapor phase media is propagated from a probe outlet to provide a controlled vapor-to-liquid phase change in an interface with tissue to thereby apply ablative thermal energy delivery.Type: GrantFiled: February 20, 2009Date of Patent: March 27, 2018Assignee: Tsunami MedTech, LLCInventors: Michael Hoey, John H.

Patent number: 9924993Abstract: An electrosurgical system for tissue cauterization may include a user interface, a front panel display, an electrosurgical generator, a power supply of the electrosurgical generator, a system control of the electrosurgical generator, an RF system of the electrosurgical generator, and a bipolar forceps assembly. The electrosurgical system may be configured to cauterize a tissue. A tissue cauterization may include system activation, tissue impedance analysis, establishment of tissue cauterization parameters, monitoring and adjustment of tissue cauterization, and system deactivation. The establishment of tissue cauterization parameters may include establishing a tissue cauterization curve configured to minimize an amount of time required to cauterize a tissue.Type: GrantFiled: April 23, 2014Date of Patent: March 27, 2018Assignee: Kogent Surgical, LLCInventors: William J Bowers, Gregg D Scheller

Patent number: 9924994Abstract: An apparatus and method for performing cardiac ablations employs a catheter comprising an anchoring device and an ablating device to perform the ablations to electrically isolate the pulmonary veins and left atrium from surrounding atrial tissue. The anchor can comprise a balloon-type device, a stent-like device, a strut-like device, a spring-strut-like device, an umbrella-like device, a mushroom-like device, or other device that allows the catheter to maintain a position with respect to target tissue. The ablator can comprise a balloon ablator, an umbrella ablator, a pinwheel ablator, an umbrella ablator incorporating a cinch mechanism, a mushroom balloon ablator and a segmented balloon or pinwheel ablator. The anchor and ablator can also comprise a combination mushroom balloon anchor section and mushroom balloon ablator section. The anchor and ablator can include electrodes for measuring a conductance therebetween when in deployed position, so as to determine the effectiveness of the ablation.Type: GrantFiled: November 1, 2012Date of Patent: March 27, 2018Assignee: Ablacor Medical CorporationInventors: Martin J. Sklar, Howard E. Guthermann, Howard Ring
