Publication number: 20160228130Abstract: A surgical drill bit is formed by a cylindrical body that comprises a distal fluted drill section, a fluted midsection and a proximal drive transmission shank. The distal end of the drill section forms the drill point of the surgical bit and comprises at least two opposed cutting edges that extend from the tip of the drill point to the leading edge of a land defined by the outer surface of a respective drill point flute. The outside diameter of the midsection is less than the outside diameter of the drill section. In cross section the flute consists of a land radially extending from an enlarged central web. A small conical tip is concentrically located on the drill point.Type: ApplicationFiled: February 9, 2015Publication date: August 11, 2016Applicant: CUTTING EDGE MEDICAL LLCInventors: Franc Koljaka, David Y Phelps

Publication number: 20140135893Abstract: Disclosed is a conduit that provides a bypass around an occlusion or stenosis in a coronary artery. The conduit is a tube adapted to be positioned in the heart wall to provide a passage for blood to flow between a heart chamber and a coronary artery, at a site distal to the occlusion or stenosis. The conduit has a section of blood vessel attached to its interior lumen which preferably includes at least one naturally occurring one-way valve positioned therein. The valve prevents the backflow of blood from the coronary artery into the heart chamber.Type: ApplicationFiled: October 31, 2013Publication date: May 15, 2014Applicant: JenaValve Technology, Inc.Inventors: Peter J.

Publication number: 20130345703Abstract: A method for capturing small objects in a confined space such as an artery or duct in a body by bringing an elongated flexible body having a distally disposed operative head provided with a plurality of nanostructures into proximity with the object. When in proximity intermolecular forces are created between the nanostructures and the object that attract the object to the operative head. By application of high frequency electrical current the nanostructures act as electrical knives to cut away or cauterize an object.Type: ApplicationFiled: July 31, 2013Publication date: December 26, 2013Applicant: Creosalus, Inc.Inventors: David Y.

Patent number: 6953481Abstract: A conduit is provided to provide a bypass around a blockage in the coronary artery. The conduit is adapted to be positioned in the myocardium or heart wall to provide a passage for blood to flow between a chamber of the heart such as the left ventricle and the coronary artery, distal to the blockage. The stent is self-expanding or uses a balloon to expand the stent in the heart wall. Various attachment means are provided to anchor the stent and prevent its migration.Type: GrantFiled: June 23, 2004Date of Patent: October 11, 2005Assignee: Percardia, Inc.Inventors: David Y.

Patent number: 6949080Abstract: A stent suitable for implantation in myocardial tissue to enhance perfusion therein may include a tubular member having first and second ends and a lumen. The first end of the stent may be configured to pierce myocardial tissue and the lumen may be configured to be placed in flow communication with a coronary vessel. The stent may further include a means for retaining the tubular member within the myocardial tissue. A method for implanting the stent may include positioning the first end of the stent at a desired implantation site and applying force to the second end of the stent to implant the stent within the myocardial tissue. The method may further include engaging the means for retaining with the myocardial tissue to retain the stent in position.Type: GrantFiled: August 15, 2002Date of Patent: September 27, 2005Assignee: Percardia, Inc.Inventors: Scott J.

Publication number: 20040186507Abstract: Described herein are various methods and apparatuses for delivering stents and other devices into the myocardium of a patient. One preferred stent delivery system provides access to the insertion site in the myocardium by advancing a delivery catheter through a blockage in a coronary artery, or around the blockage through a coronary vein or through a channel or tunnel formed around the blockage. In one embodiment, once the distal end of the delivery catheter is adjacent the myocardium, an angled bend is created in the catheter by actuating expandable steering guides mounted to the catheter which cooperate with the walls of the blood vessel to cause the catheter to turn. Then, a guidewire is advanced through the delivery catheter and into the myocardium. In another embodiment, a tip-deflecting pull wire extends from the distal end of the delivery catheter which may be actuated to turn towards and then inserted into the myocardium.Type: ApplicationFiled: July 24, 2003Publication date: September 23, 2004Applicant: Percardia, Inc.Inventors: Todd A. Hall, Greg R. Furnish, Simon M. Furnish, Scott J. Wolf, Peter J. Wilk, David Y. Phelps, Vincent Pompili

Publication number: 20040147869Abstract: Left ventricular conduits and related methods are disclosed for achieving bypass of a partially or completely occluded coronary artery. More broadly, conduits for allowing communication of bodily fluids from one portion of a patient's body to another and related methods are disclosed, including conduits for forming a blood flow path from a chamber of the heart to a vessel or from one vessel to another. In other embodiments, the conduits achieve a coronary artery bypass by allowing blood communication between the left ventricle and the coronary artery or between a proximal portion of the coronary artery and a distal portion of the coronary artery. The conduits may be placed completely through the heart wall or extend only partially therein. Conduits may take on a variety of configurations for allowing the control of blood flow therethrough, including curved or tapered shapes.Type: ApplicationFiled: October 9, 2003Publication date: July 29, 2004Applicant: Percardia, Inc.Inventors: Scott J.
