Abstract: The present disclosure comprises handle assemblies for intravascular treatment devices. In one embodiment, a handle assembly comprises an actuator for deflecting a distal region of an intravascular treatment device. In one embodiment, a handle assembly comprises a rotator for rotating an intravascular treatment device independently of the handle assembly. In one embodiment, a handle assembly comprises a rotation limiting element for limiting independent rotation of an intravascular treatment device relative to the handle assembly. Methods and systems for intravascular delivery, deflection and placement of an intravascular treatment device via a handle assembly of the present invention are also provided.

Abstract: Hardware-enforced zoning is provided in Fiber Channel switches to protect against breaching of assigned zones in a switch network which can occur with software-based zoning techniques. The invention provides logic for performing a hardware-based validation of the Source ID S_ID of frames both at the point where the frame enters the Fiber Channel fabric, and at the point where the frame leaves the fabric. The S_ID is verified against an inclusion list or table of allowable S_IDs, which can be unique for each fabric port. The invention provides a way to increase the range of sources an inclusion table can express, by implementing wild cards, on an entry-by entry basis. If the S_ID is valid, it will enter the fabric and route normally. If invalid, the frame will not be routed but will be disposed of by the fabric according to FC rules.

Abstract: The Fibre Channel Credit Extender (FCCE) (600) is a network device that is disposed between and connected to an end node (210) and an optical repeater (220). The FCCE (600) contains as many buffer credits as necessary, to solve bandwidth problems in a network. In a situation where maximum bandwidth is required in both directions of a link, the FCCE (600) breaks a single logical link into three physically separated “linklets.” The short-distance linklets attain maximum bandwidth by use of the existing buffer credits of the end nodes. The long-distance linklet attains maximum bandwidth by use of very high receive buffer credits in the FCCEs (600). In this way, only those links that need maximum bandwidth over distances not covered by end-node credit counts need be attached to an FCCE (600). The FCCE (600) contains the optical repeater to gain distance on that link, and contains high credit count receive buffers to gain bandwidth on the link.

Abstract: Medical device and methods for delivery or implantation of prostheses within hollow body organs and vessels or other luminal anatomy are disclosed. The subject technologies may be used in the treatment of atherosclerosis in stenting procedures. For such purposes, a self-expanding stent is deployed in connection with an angioplasty procedure with a corewire actuated delivery system having a fixed distal stent-carrying extension. Withdrawal of the corewire retracts a restraint freeing the stent from a collapsed state, whereupon the stent assumes an expanded configuration set in apposition to the interior surface of a vessel lumen in order to help maintain the vessel open.

Abstract: Medical device and methods for delivery or implantation of prostheses within hollow body organs and vessels or other luminal anatomy are disclosed. The subject technologies may be used in the treatment of atherosclerosis in stenting procedures. For such purposes, a self-expanding stent may be deployed in connection with an angioplasty procedure with a sliding restraint based delivery system adapted for simplified use. In the system, the sliding restraint is sized, in coordination with a fixed sleeve accepting a core wire to actuate the restraint to effect an anchoring function with the sleeve so that the stent is not inadvertently advanced during deployment.

Abstract: A high performance switch fabric element and flexible link interconnection topologies and frame addressing techniques therefor are disclosed. The fabric element, which may be a 16 port ASIC with internal steerable interconnection among all ports. The fabric element ports each have a unique local routing table, thereby avoiding the need for a global routing table for ports as is provided in the prior art. This also permits addressing and routing from port to port within the fabric element without need for look-up references from off the fabric element, thereby contributing to speed. The fabric element can be used in multiples interconnected by unique link interconnection techniques including cascade, mesh, microstaging, and combinations thereof. These link interconnection techniques provide unique switch topologies that permit high performance switching chassis or network box having a significantly larger number of ports than is achievable with the prior art techniques.

Abstract: A sample retention apparatus for use in a device for measuring hemostasis. The device for measuring hemostasis may include a sample articulation apparatus including a guide shaft coupled for articulating motion to a drive motor, a sample carrier secured to and axially moveable along the guide shaft between a sample ready position, a sample testing position and a sample ejection position. The sample carrier therefore articulates in unison with the articulating motion of the guide shaft. A measuring apparatus may include a sensing column. The sample retention apparatus may include a sample cup defining a volume within which a sample may be disposed. The sample cup may be adapted to be operably positioned within an aperture formed within the sample carrier. The sample testing apparatus may also include a sample pin that is engageable with the sensing column. The sample pin may include a tip portion for extending into the sample cup.
