Patent number: 10925474Abstract: The present disclosure is a device and method associated with the delivery of medical devices in the pericardial space using a minimally invasive approach with direct visualization. More specifically, the device can be used to deliver permanent pacing, defibrillation and cardiac resynchronization leads, as well as leadless pacemakers for cardiac rhythm management to the epicardial surface of the heart. A subxiphoid procedure is proposed as a minimally invasive alternative to thoracotomy, while the delivery tool incorporates a camera for direct visualization of the procedure. The tool also incorporates a steerable catheter to provide selective control of the placement and orientation of the medical device in the pericardial space.Type: GrantFiled: February 18, 2015Date of Patent: February 23, 2021Assignee: CHILDREN'S NATIONAL MEDICAL CENTERInventors: Charles Berul, Justin Opfermann, Axel Krieger, Peter Kim, Tanya Davis, Bradley Clark

Patent number: 10881279Abstract: An instrument for use with an endoscope may include an elongate section configured to move exterior to the endoscope. The elongate section may include a distal end and a proximal end. The instrument may also include an end effector attached to the distal end of the elongate section, and an actuation device attached to the proximal end of the elongate section. The actuation device may be configured to operate the end effector. The instrument may also include a guiding member coupled to the elongate section. The guiding member may be configured to be coupled to an external surface of the endoscope to permit the guiding member to move longitudinally relative to the endoscope. The guiding member may be coupled to the elongate section such that the end effector may extend past a distal end of the endoscope and move in a transverse direction independent of the movement of the distal end of the endoscope.Type: GrantFiled: October 30, 2019Date of Patent: January 5, 2021Assignee: Boston Scientific Scimed, Inc.Inventor: Barry Weitzner
