20080253370 | MAINTENANCE OF BANDWIDTH ALLOCATION FOR TRAFFIC INCLUDING MULTICASTS - Multicast packets that are received on a port of a network device and forwarded to multiple output ports are stored in memory and respective primary control entries which define them are converted to secondary control entries defining multiple unicast packets before a scheduling algorithm is applied. The packets are reconstituted after the application of the scheduling algorithm has been applied to the control entries. For VPLS packets that are received on a single port and replicated multiple times on one or more output ports, a replication database may be used in conjunction with a replication engine to convert the control entry for a received packet into multiple control entries defining unicast packets for each of the destination ports before the scheduling algorithm is applied. This method is applicable to the replication of packets onto a Virtual Private LAN. | 10-16-2008 |

20080269615 | TRANSDUCER WITH MULTIPLE RESONANT FREQUENCIES FOR AN IMAGING CATHETER - A single transducer element that is capable of oscillation at a plurality of natural resonant frequencies may be used in an ultrasonic imaging catheter assembly including a catheter body configured to be inserted and guided through the vascular system of a living being, a lumen and a rotatable imaging core adapted to pass through the lumen, the imaging core including a flexible drive-shaft. Because the transducer element is capable of oscillation at a plurality of natural resonant frequencies, a user can switch from one frequency to another in order to improve the depth of field or resolution without having to switch out the catheter or imaging core. | 10-30-2008 |

20080215046 | MEDICAL DEVICE CONTROL SYSTEM - A medical device for use by an operator to perform a medical procedure in a body includes a handle to be held by the operator, a shaft attached to the handle and an actuating assembly to control functions associated with the medical procedure. The shaft includes an operative distal portion to perform a medical procedure in the body. The medical device may be part of an ablation catheter system that is programmed to correlate one or more functions with the actuation of the actuating assembly. Multiple actuating assemblies may be provided. Each actuating assembly may be a button. Other types of actuating assemblies may also be used, such as switches or a trackball. The actuating assembly may also be provided on a sleeve that may be selectively attached to the handle of the catheter or the physician operating the catheter, for example. | 09-04-2008 |
