Abstract: A rectifier circuit has a cathode node, an anode node, a rectifier switch, an auxiliary switch, an operating power capacitor and a rectifier controller supplied with power by the operating power capacitor. The rectifier switch is electrically connected to the auxiliary switch. When the rectifier controller turns OFF both the rectifier and auxiliary switches, the rectifier circuit supports a first loop, directing a first current to flow into the rectifier circuit from the anode node, through the operating power capacitor, and away the rectifier circuit from the cathode, so the operating power capacitor is charged. When the rectifier controller turns ON both the rectifier and auxiliary switches, the rectifier circuit supports a second loop directing a second current to flow into the rectifier circuit from the anode node, through the rectifier switch, and away the rectifier circuit from the cathode, without charging the operating power capacitor.

Abstract: An isolated power supplies converts an input power source in a primary side into an output power source in a secondary side, capable of transmitting a signal from the secondary side to the primary side via a transformer. The transformer has a primary winding connected with a main switch, and a secondary winding connected with a secondary-side switch. A primary-side controller controls the main switch. A secondary-side controller controls the secondary-side switch and detects a demagnetization time of the transformer. Before the end of the demagnetization time, the secondary-side controller turns OFF the secondary-side switch to signal, via the transformer, the primary-side controller, which in response turns ON the main switch to operate the isolated power supply in a continuous-conduction mode or in a boundary mode.

Abstract: An embodiment includes a process for treating an abdominal aortic aneurysm (AAA) endoleak with a shape memory polymer (SMP) foam device. First, a bifurcated stent graft is placed within the aneurysm while a micro guidewire is positioned within the aneurysm for future catheter access. Second, after placing the iliac graft extension, a catheter is introduced over wire to deliver embolic foams. Third, embolic foams expand and conform to the aneurysm wall. Fourth, embolic foams create a stable thrombus to prevent endoleak formation by isolating peripheral vessels from the aneurysm volume.
