Abstract:
An apparatus for delivering devices. The apparatus comprises a catheter with an elongated shaft having a first lumen and a second lumen extending therethrough. The apparatus further comprises a distal section with a lumen in communication with a port in a distal end of the catheter and with the first lumen and the second lumen. The first lumen is configured for a first device and the second lumen is configured for a second device to be disposed therein. The apparatus further comprises a proximal adapter coupled to the elongated shaft with a first port in communication with the first lumen and a second port in communication with the second lumen.
Abstract:
A device and method for converting a low voltage signal into a high voltage signal are provided, which can be implemented by using a low voltage CMOS manufacturing process to convert a low voltage signal of 0V to 1.5V into a high voltage signal of 2.5V to 1.25V. According to one preferred embodiment, PMOS transistors are employed to perform voltage level conversion and supply voltages of 1.25V and 2.5V are supplied to the PMOS transistors. During the conversion, no current path exists between the supply voltages thus effectively reducing static power consumption. In addition, the low level of the high voltage signal is outputted through the drain and source of the transistor so that the low level of the high voltage signal can be accurately defined and not affected by manufacturing parameters.
Abstract:
A clock circuit for supporting a plurality of memory module types is provided. The clock circuit is connected to a first type memory module slot, and a second type memory module slot. The clock circuit includes a clock generator for producing a clock signal and a clock buffer having doubly defined clock pins for outputting the first type memory clock signal or the second type memory clock signal. The clock buffer receives the clock signal and outputs a first type memory clock signal to the first type memory clock pin. The doubly defined clock pin is also capable of outputting a second type memory clock signal to the second type memory clock pin. This invention is capable of using just a single clock buffer to drive a plurality of different memory module types.

Each of the video trunk combiners is connected between the first level network device and at least one user end, and receives the at least one of the frequency channels provided by at least two of the media storage ends via the first level network device.
Abstract:
The present invention is directed to implantable devices (e.g., drug-delivery stents) containing nuclear receptor ligands. The nuclear receptor ligands may be, inter alia, PPAR ligands or retinoids. The invention also provides for a method of treating or preventing vascular disorders (e.g., restenosis) and related disorders using the nuclear receptor ligand-containing devices.
