  • Publication number: 20040152947
    Abstract: The various aspects of the invention pertain to devices and related methods for treating heart conditions, including, for example, dilatation, valve incompetencies, including mitral valve leakage, and other similar heart failure conditions. The devices and related methods of the present invention operate to assist in the apposition of heart valve leaflets to improve valve function. According to one aspect of the invention, a method improves the function of a valve of a heart by placing an elongate member transverse a heart chamber so that each end of the elongate member extends through a wall of the heart, and placing first and second anchoring members external the chamber. The first and second anchoring members are attached to first and second ends of the elongate member to fix the elongate member in a position across the chamber so as to reposition papillary muscles within the chamber.

    Abstract: Devices and related methods for treating heart conditions, including, for example, dilatation, valve incompetencies, including mitral valve leakage, and other heart failure conditions, may operate to assist in the apposition of heart valve leaflets to improve valve function. A method for improving the function of a valve of a heart includes placing an elongate member transverse a heart chamber so that each end of the elongate member extends through a wall of the heart, and placing first and second anchoring members external the chamber. The first and second anchoring members are attached to first and second ends of the elongate member to fix the elongate member in a position across the chamber so as to reposition papillary muscles within the chamber. A method of treating the valve may include real-time monitoring the valve function and adjusting the device based on data obtained during the real-time monitoring.

  • Publication number: 20030233022
    Abstract: Devices, systems and methods for improving the function of a valve of a heart by implanting the device adjacent the valve such that the device indirectly applies a force to the valve and increases coaptation of the leaflets, or otherwise improves valve function. The device may be implanted in a position that does not directly contact the valve structures. The force may be applied to a wall of the heart, and the force may be an inward force applied to two walls of the heart, such as the left ventricular free wall and the ventricular septum, or the left ventricular free wall and the right ventricular free wall, to improve mitral valve function.

  • Patent number: 6397850
    Abstract: An apparatus and method are disclosed for accurately detecting the detachment of both electrically conductive and non-conductive implants which have been introduced to and are intended to remain at a desired therapeutic site. The detachment detection apparatus may include a conductive or an electrically-isolated implant, such as a vasoocclusive coil, connected to a wire by an electrolytically severable joint. The detachment assembly further includes a power supply having a direct current drive circuit for supplying a direct current to the joint, an alternating current drive circuit for independently supplying an alternating current to the joint, and an alternating current monitoring circuit for monitoring an alternating current level of the alternating current supplied to the joint. The detection assembly includes a central processing unit for selecting a first mode and a second mode for determining a detachment threshold level indicating detachment of the implant.
