Abstract: A system for enabling the insertion and removal of an embolic protection device, for capturing and retaining embolic debris which may be created during the performance of a therapeutic interventional procedure in a stenosed or occluded region of a blood vessel. The system, in an embodiment thereof, is capable of enabling at least one operator to control the delivery and removal of an embolic protection device to a position in a patient's vasculature distal to an interventional procedure site, to enable the exchange of the delivery and recovery system. The system, in another embodiment thereof, includes a delivery system and a recovery system which are capable of enabling the delivery and recovery of an embolic protection device so as to maintain a clinically acceptable profile and flexibility through the patient's vasculature.

Abstract: A catheter assembly is provided having an inner member and an outer member extending along a longitudinal axis, the inner member and the outer member having a coaxial configuration and dimensioned for relative axial movement. The outer member may include an anti rotation member adapted to engage with a longitudinal slot formed on the inner member so as to maintain rotational alignment between inner member and outer member. The inner member can be made with a proximal portion made from a tubing such as hypotubing or a coil tubing. The inner member also may be made with a proximal portion made with a support mandrel. A coil tubing can be utilized to form the guide wire receiving member which is attached to the inner member.

Abstract: A single, common correlation filter (CF) core is provided in a wireless system using CDMA. A plurality of channels with different data rates are provided in the wireless system. The channels provided in the wireless system include the access channel, the maintenance channel, and the traffic channel in which information (e.g., pilot or data symbols or both) is transmitted at the tier 1, tier 2 and tier 3 rates. The data rate for transmitting the information is programmable by digital signal processor (DSP). A user-unique code, such as a PN code, is applied to the information being transmitted in the channels of the wireless system. The information is QPSK modulated and transmitted in any one of the channels at any data rate. The transmitted information is correlated at the smallest data rate (i.e., the tier 1 rate) in the correlation filter (CF) of the wireless system by time multiplexing delayed versions of the PN code to the correlation filter core.

Abstract: An embolic protection device for use in a blood vessel when an interventional procedure is being performed in a stenosed or occluded region to capture any embolic material which may be created and released into the bloodstream during the procedure. The device includes a filtering assembly having a self-expanding strut assembly and a filter element attached thereto. In one embodiment, the filtering assembly is attached to the distal end of a guide wire and is deployed within the patient's vasculature as the guide wire is manipulated into the area of treatment. A restraining sheath placed over the filtering assembly in a coaxial arrangement maintains the filtering assembly in its collapsed position until it is ready to be deployed by the physician. Thereafter, the sheath can be retracted to expose the filtering assembly which will then self-expand within the patient's vasculature.

Abstract: An interface circuit providing a high speed bus. According to one embodiment, the interface circuitry includes a plurality of I/O pins coupled to a plurality of bus drivers, wherein each bus driver is configured to adjust the rise time, fall time, and drive strength of outputs signal on the I/O pins based on process-voltage-temperature ("PVT") conditions. The circuitry used to adjust the I/O outputs includes a slew rate control circuit, a current control circuit, and a delay lock loop ("DLL").

Abstract: A hair clip for gripping strands of a woman's hair arranged in a desired coiffure includes upper and lower tapered jaw pieces having front portions which curve arcuately downwards in a manner suggestive of the jaw parts of a flamingo's bill. The rear portions of the jaw pieces are joined by a transversely disposed pivot pin which permits relative motion of the upper and lower jaw pieces in a vertical plane. A coil spring encircling the pivot pin urges apart the rear portions of the upper and lower jaw pieces, thereby urging the front arcuately downwardly curved portions of the jaw pieces into compressive clamping contact. Preferably, the front portion of the lower jaw piece is shorter and more curved than the front portion of the upper jaw piece, and is received in a longitudinally disposed channel formed in the lower surface of upper jaw piece.

Abstract: A circuit for determining the carry out from the addition of two numbers independent of the determination of the sum of the two numbers including apparatus for determining a first carry out from each bit position for a carry in of a first value, apparatus for determining a second carry out from each bit position for a carry in of a second value, a plurality of apparatus for utilizing the first and second carry out values from two or more adjacent bit positions to produce a first carry out from each plurality of bit positions for a carry in of a first value, and second carry out from each plurality of bit positions for a carry in of a second value, and apparatus for selecting between the first and second values based on the actual values of the carry ins.
