Patent number: 9119661Abstract: An atherectomy device is disclosed, which is rotationally driven by an electric motor. In some designs, the device includes features unavailable on gas turbine-driven systems, such as the storing in memory of low/medium/high preset rotation speeds for particular models of handle, calculations of the amount of saline left in the IV and associated warnings when it gets sufficiently low, and automatic adjustment of the IV pump rate to a predetermined or calculated level when the rotational speed of the motor is changed. The electric motor has far more rotational inertia than a comparable gas turbine, so the system includes a control mechanism that helps prevent damage from excessive torque being applied to the distal end of the drive shaft. When an obstruction at the distal end is detected, by a drop in the motor rotational speed, the motor is released and is allowed to spin freely as a flywheel.Type: GrantFiled: September 21, 2012Date of Patent: September 1, 2015Assignee: Cardiovascular Systems, Inc.Inventors: Jody Lee Rivers, Charles A.

Patent number: 8911459Abstract: A method of removing material from a blood flow lumen includes providing a device having a cutting element and an opening, the cutting element being movable relative to the opening. The method then includes advancing the device through a patient's vascular system to the blood flow lumen. Finally, the method involves moving the cutting element and the opening relative to the blood flow lumen so that a continuous piece of material is severed by the cutting element and directed into the opening as the cutting element and opening move through the blood flow lumen, the continuous piece of severed material being directed into the device for removal from the patient. The method may include providing a device having a rotatable cutter that, in some embodiments, is not parallel to the longitudinal axis of the device, is movable, has retracted and deployed positions, or any combination thereof.Type: GrantFiled: June 28, 2012Date of Patent: December 16, 2014Assignee: Covidien LPInventors: John B. Simpson, Himanshu Patel, Greg Stine, Brett Follmer, Michael H. Rosenthal, Mehrdad Farhangnia

Patent number: 8906053Abstract: A method for treating a brain tumor includes providing a surgical instrument having an inner member and an outer member. The outer member has a distal region forming a cutting window and an optional distal elevator tip. The inner member is rotatably received within the outer member, and has a cutting tip that is exposed at the window. The cutting tip and the distal region of the outer member combine to define a cutting implement. An opening is created through the patient's skull to provide access to a brain tumor target site. The cutting implement is delivered through the opening to the target site. The elevator tip is inserted partially between the tumor and tissue of the target site, and the cutting tip is placed into contact with the tumor and operated to cut the tumor. The target site is selectively aspirated to remove cut tumor tissue.Type: GrantFiled: November 12, 2007Date of Patent: December 9, 2014Assignee: Medtronic Xomed, Inc.Inventors: Dana A. Oliver, Louis M. Shadeck, Roy Galvin, Robert Spetzler

Patent number: 8905945Abstract: A body fluid sampling system for use on a tissue site includes a single drive force generator. A plurality of penetrating members are operatively coupled to the force generator. The force generator moves each of the members along a path out of a housing with a penetrating member exit, into the tissue site, stops in the tissue site, and withdraws out of the tissue site. A flexible support member couples the penetrating members to define a linear array. The support member is movable and configured to move each of the penetrating members to a launch position associated with the force generator.Type: GrantFiled: March 29, 2012Date of Patent: December 9, 2014Inventors: Dominique M. Freeman, Dirk Boecker, Don Alden

Publication number: 20140358170Abstract: Articulating, safe and efficient cutting heads for removing a target tissue from a subject during a surgical procedure are provided, the cutting heads composing a part of systems that address several problems, including clogging of state-of-the-art systems during removal of such tissue, for example. The target tissue can include any tissue that is accessible through a small surgical opening, for example, a joint tissue such as a meniscus or an intervertebral tissue, such as a nucleus pulposus. The devices can be referred to as orthopedic tissue removal devices having cutting heads associated with vacuum systems, making the systems useful in several procedures, including X-LIF (lateral approach to an intervertebral fusions) procedures, T-LIF (transforaminal approach to intervertebral fusions) procedures, P-LIF (posterior approach to intervertebral fusions), and a percutaneous, transforaminal approach (Kambin triangle access).Type: ApplicationFiled: August 19, 2014Publication date: December 4, 2014Inventors: John To, Fred Osorio

Patent number: 8900261Abstract: A dermatological skin treatment device is provided. The device comprises a handpiece and a cutting tool, wherein the tool is inserted through the conduit and percutaneously inserted into a tissue disposed within a recessed area of the handpiece. The device and method cut the fibrous structures under the skin that cause cellulite at an angle substantially parallel to the surface of the skin and replace these structures with a non-cellulite forming structure by deploying a highly fibrous mesh through a single needle hole to create a highly fibrous layer directly or through wound healing processes.Type: GrantFiled: May 29, 2014Date of Patent: December 2, 2014Assignee: Ulthera, Inc.Inventors: Robert L Clark, III, James E.

Patent number: 8888784Abstract: A dual bladed surgical saw and method of use. Two blade assemblies are attached to a saw body. Each blade assembly includes an oscillator driving a blade, and teeth on each blade. The blades are disposed at a pre-determined blade angle relative to each other, thus allowing two cuts to be made simultaneously and independently at the blade angle relative to each other. The blade assemblies may be rotatable relative to each other, which allows the pre-set blade angle to be varied appropriate to the procedure contemplated. One embodiment uses a slotted protractor bearing protractor indicia, and a threaded fastener to set the blade angle. Another embodiment uses shims between blade assembly arms to quickly and accurately set the blade angle. Method steps include pre-setting the blade angle, and making two cuts simultaneously at an angle relative to each other equal to the blade angle.Type: GrantFiled: August 29, 2012Date of Patent: November 18, 2014Inventor: Christopher B.
