Patent number: 9173712Abstract: Medical devices, systems, and methods reduce the distance between two locations in tissue in a minimally invasive manner, often for treatment of congestive heart failure. In one embodiment, an anchor of an implant system may, when the implant system is fully deployed, reside within the right ventricle in engagement with the ventricular septum. A tension member may extend from that anchor through the septum and an exterior wall of the left ventricle to a second anchor disposed along an epicardial surface of the heart. Deployment of the anchor within the right ventricle may be performed by inserting a guidewire through the septal wall into the right ventricle. The anchor may be inserted into the right ventricle over the guidewire and through a lumen of a delivery catheter. Delivering the anchor over the guidewire may provide improved control in the delivery and placement of the anchor within the right ventricle.Type: GrantFiled: September 30, 2012Date of Patent: November 3, 2015Assignee: BioVentrix, Inc.Inventors: Lon Annest, Murray Sheldon, Kevin Van Bladel, Ernie Heflin, William Butler, Andrew Wechsler, John Bower, Rovil Arcia

Patent number: 9161770Abstract: A surgical instrument can comprise an elongate tube including a camming rod and an actuation mechanism operably connected to the camming rod; a first jaw spine having a first cam slot; and a second jaw spine having a second cam slot, the second jaw spine pivotally connected to the first jaw spine at a common pivot pin connected to the elongate tube. A camming pin rides along first and second interior camming surfaces and closes the jaw spines when the camming rod moves proximally. When the camming rod moves distally, a camming projection rides on first and second exterior camming surfaces on proximal sides of the first and second jaw spines and opens the jaw spines. One camming surface on each jaw spine facilitates closing the jaw spines while the other camming surface on each jaw spine facilitates opening the jaw spines. These two camming surfaces can be widely separated.Type: GrantFiled: September 30, 2013Date of Patent: October 20, 2015Assignee: Applied Medical Resources CorporationInventors: Russell E.
