Patent number: 8834519Abstract: A device and method for obliterating or occluding a body cavity or passageway, in particular, the left atrial appendage of a patient's heart. The procedure can be carried out intraoperatively, but is preferably carried out percutaneously by use of a delivery catheter to position an occluding device adjacent a patient's left atrial appendage. The occluding device may prevent the passage of embolic or other material to or from the left atrial appendage by volumetrically filling the appendage, closing the opening of the appendage with an occluding member, or pulling the tissue around the opening of the appendage together and fixing it in a closed state.Type: GrantFiled: November 18, 2011Date of Patent: September 16, 2014Assignee: Artritech, Inc.Inventors: Erik J. van der Burg, Dino De Cicco, Andrew G. C. Frazier, Alexander K. Khairkhahan, Marc S. Kreidler, Michael D. Lesh, Chad C. Roue

Patent number: 8828071Abstract: A system for treating a bifurcation includes first and second delivery catheters, each having an expandable member. A stent having a side hole is disposed on the second delivery catheter. A portion of the first delivery catheter is disposed under a portion of the stent. The first delivery catheter is slidable relative to the second delivery catheter, and the first delivery catheter passes through the side hole. Expansion of the first expandable member expands a proximal portion of the stent in a main branch vessel, and expansion of the second expandable member expands a distal portion of the stent in a side branch vessel.Type: GrantFiled: March 24, 2011Date of Patent: September 9, 2014Assignee: Advanced Bifurcation Systems, Inc.Inventors: Henry Bourang, Mehran Khorsandi

Patent number: 8795321Abstract: An intravascular implant delivery system carries an implant by retaining an engagement member engaging the implant in a position proximal of an aperture at a distal end of the delivery system. The engagement member is retained proximal to the aperture by a cord that obstructs the movement of the engagement member through the aperture. The engagement member is free to rotate and move within an area defined by the delivery system, allowing the implant to react to forces imparted to the implant by the movement of the delivery system and implant through a delivery catheter. Once the implant is in a desired implant position, the cord is moved away from an aperture and the engagement member is allowed to move away from the delivery system.Type: GrantFiled: August 30, 2011Date of Patent: August 5, 2014Assignee: Covidien LPInventors: Brian Michael Strauss, Earl Howard Slee, Ramon Torres Carrillo, Khoa Dang Vu, William Robert Patterson, Jessica Liang, Richard Stephen Bein, Todd Jeffrey Hewitt, Stacy Leon Faught, Vince Divino, Darrell Christopher Drysen, Mark Philip Ashby, Justin Arthur Klotz, Maria De Jesus Sanson, Scott William Brennan, Lawrason Charles Wilbur, Lester Eugene Oestreich

Patent number: 8628553Abstract: Expanding or foaming adhesives are used to reduce the stomach volume to reduce the caloric intake and weight of a patient. A web structure is attached inside the stomach and an expanding or foaming adhesive is applied to the web structure. The expanding or foaming adhesive attaches to the web structure and to the stomach to partition the stomach. The partition barrier divides the stomach volume into a reduced volume available for food storage and an empty volume that the food cannot enter. The reduced volume enables the patient to feel full faster and reduce caloric intake. A passageway can be provided between the two volumes near the base of the stomach to allow food or fluids to exit from the empty volume.Type: GrantFiled: November 8, 2006Date of Patent: January 14, 2014Assignee: Ethicon Endo-Surgery, Inc.Inventors: James W. Voegele, Douglas J. Turner, Mark S. Ortiz, Frederick E. Shelton, IV

Patent number: 8608773Abstract: Robotic surgical tools, systems, and methods for preparing for and performing robotic surgery include a memory mounted on the tool. The memory can perform a number of functions when the tool is loaded on the tool manipulator: first, the memory can provide a signal verifying that the tool is compatible with that particular robotic system. Secondly, the tool memory may identify the tool-type to the robotic system so that the robotic system can reconfigure its programming. Thirdly, the memory of the tool may indicate tool-specific information, including measured calibration offsets indicating misalignment of the tool drive system, tool life data, or the like. This information may be stored in a read only memory (ROM), or in a nonvolatile memory which can be written to only a single time. The invention further provides improved engagement structures for coupling robotic surgical tools with manipulator structures.Type: GrantFiled: September 18, 2006Date of Patent: December 17, 2013Assignee: Intuitive Surgical Operations, Inc.Inventors: Michael J. Tierney, Thomas Cooper, Chris Julian, Stephen J. Blumenkranz, Gary S. Guthart, Robert G. Younge

Patent number: 8608790Abstract: A catheter assembly for treatment of a vessel bifurcation. The catheter assembly is adapted for use with a single guidewire, wherein the guidewire is used to both position the catheter assembly within a main vessel of the vessel bifurcated and then be advanced into a branch vessel of the vessel bifurcated. A guidewire lumen of the catheter assembly is defined by a portion of a catheter shaft of the catheter assembly and a portion of a side catheter branch of the catheter assembly. The side catheter branch extends from a distal end of the catheter shaft at a proximal location and is connected at a distal location to a main catheter branch. After the catheter assembly has been advanced over the guidewire to a position within the main vessel at the vessel bifurcation, the guidewire is retracted, a portion of the side catheter branch is advanced into the branch vessel, and the guidewire is advanced into the branch vessel.Type: GrantFiled: October 6, 2006Date of Patent: December 17, 2013Assignee: Boston Scientific Scimed, Inc.Inventors: Hans Valencia, Andrzej Malewicz, Adam Jennings

Patent number: 8585732Abstract: A foreign body retrieval system includes a pusher and a retrieval element connected to the distal end of the pusher. The retrieval element includes one or more gripping members that are movable between a retracted position and an extended position. In the extended position, the gripping members extend in a radial and outward direction from the retrieval element in order to snag and capture a foreign body.Type: GrantFiled: June 14, 2006Date of Patent: November 19, 2013Assignee: DePuy Synthes Products, LLCInventor: Damian Tomlin

Patent number: 8579805Abstract: The present invention is directed to a dilator having a stiffened shaft for use as part of an introducer sheath assembly. The dilator includes a stiffener tube and a tip of the dilator which extends distally to the dilator stiffener tube. The transition between the stiffener tube and the tip of the dilator is positioned such that when the dilator is positioned within the catheter sheath, the transition is also positioned within the catheter sheath. By positioning the transition between the stiffener tube of the dilator and the tip of the dilator inside the catheter sheath, the catheter sheath can provide strain relief subsequent to lateral movement of the tip of the dilator in a manner that can prevent kinking of the dilator tip at the transition between the stiffener tip and the tip of the dilator.Type: GrantFiled: February 6, 2006Date of Patent: November 12, 2013Assignee: Merit Medical Systems, Inc.Inventor: Nicholas Gerald Accisano, III
