Publication number: 20150272618Abstract: Described here are devices, systems, and methods for accessing the pericardial space through the pericardium. The access devices may include a plurality of elongate members having lumens that may be advanced together through the body to the pericardium. The elongate members may have different lengths and may be slideably positioned one within the lumen of another. At least one of the elongate members may comprise a distal tip configured to pierce tissue. In some instances, the access devices may also comprise a locking member to constrain the position of one elongate member relative to another.Type: ApplicationFiled: February 26, 2015Publication date: October 1, 2015Inventors: Gregory W.

Publication number: 20150164574Abstract: A surgical apparatus and methods for severing and welding tissue, in particular blood vessels. The apparatus includes an elongated shaft having a pair of relatively movable jaws at a distal end thereof. A first heating element on one of the jaws is adapted to heat up to a first temperature and form a welded region within the tissue, while a second heating element on one of the jaws is adapted to heat up to a second temperature and sever the tissue within the welded region. The first and second heating elements may be provided on the same or opposite jaws.

Publication number: 20150119884Abstract: Described here are devices, systems, and methods for closing the left atrial appendage. The methods described here utilize a closure device for closing the left atrial appendage and guides or expandable elements with ablation or abrading elements to ablate or abrade the left atrial appendage. In general, these methods include positioning a balloon at least partially within the atrial appendage, positioning a closure assembly of a closure device around an exterior of the atrial appendage, inflating the balloon, partially closing the closure assembly, ablating the interior tissue of the atrial appendage with the inflated balloon, removing the balloon from the atrial appendage, and closing the atrial appendage with the closure assembly.Type: ApplicationFiled: October 31, 2014Publication date: April 30, 2015Inventors: Gregory W.

Patent number: 8986278Abstract: Devices and methods for accessing the pericardial space of a heart are described here. Access devices may generally comprise a tissue-engaging member, a tissue-piercing member, and a guide element. The access device may be introduced to the surface of a pericardium, where the tissue-engaging member may be deployed to engage a portion of the pericardium without engaging the epicardial surface of the heart. Once the access device has engaged the pericardium, the device may manipulate the pericardium to increase the distance between a portion of the pericardium and the epicardial surface of the heart. Once a sufficient space has been created, the tissue-piercing member may be advanced to pierce the pericardium and enter the pericardial space. The guide element may then be introduced into the pericardial space to provide an access pathway to the heart for other devices.Type: GrantFiled: April 13, 2011Date of Patent: March 24, 2015Assignee: SentreHEART, Inc.Inventors: Gregory W. Fung, Russell A. Seiber, Eduardo A. Sager, Jr., Arnold M. Escano, Ryan Douglas Helmuth

Publication number: 20140336676Abstract: Described here are closure devices and methods for ligating tissue, such as the left atrial appendage. The closure devices may comprise a snare loop assembly comprising a snare and a suture loop releasably attached thereto, and a snare control. The closure devices may further comprise one or more reference markings, wherein the relative positioning between a portion of the snare control and the reference markings provides an indication of the diameter of the snare loop assembly. In some variations, when the snare loop assembly is closed around a tissue such as the left atrial appendage, the measured diameter of the snare loop assembly may help a user determine whether the snare loop assembly has been properly positioned relative to the tissue, as well as the approximate size that a suture loop may have when released from the snare loop assembly.Type: ApplicationFiled: May 7, 2014Publication date: November 13, 2014Applicant: SENTREHEART, INC.Inventors: Russell PONG, Robert L.

Patent number: 8211139Abstract: A graft provided with a flexible sealing member to substantially prevent blood from leaking between the graft a lumen into which the graft is placed. In one embodiment, the flexible sealing member may be pressed against the vascular wall by an outwardly biased spring means attached to the sealing member. In other embodiments, the sealing member may be self-positioning upon deployment of the graft. The sealing member also may be formed into the shape of a toroid, which may be filled with thrombogenic material causing blood permeating into the toroid-shaped space to coagulate therein and hold the sealing member in place. It is also contemplated that the sealing member be formed from tufts of frayed yarn protruding circumferentially from the outer surface of the graft. A method of manufacturing such tufted yarn sealing members is also disclosed.Type: GrantFiled: December 19, 2008Date of Patent: July 3, 2012Assignee: Endovascular Technologies, Inc.Inventors: Steven G.
