20150082618 | SHIELDED IMPLANTABLE MEDICAL LEAD WITH REDUCED TORSIONAL STIFFNESS - Shields within implantable leads increase the torsional stiffness of the leads. The torsional stiffness may be reduced by cutting the shield axially to break the circumferential mechanical continuity of the shield. The circumferential shielding continuity of the shield may be re-established to preserve the shielding effect in various manners. The shield may overlap onto itself to close the slot created by the cut. A shield patch may be placed across the slot created by the cut. The shield may be located between two insulation layers of the lead. The shield may be cut and then the slot closed prior to application of the outer insulation layer. The outer insulation layer may then be added over the shield. The outer insulation layer may be compliant so that once covered, the circumferential mechanical continuity of the shield remains broken. | 03-26-2015 |

20080269854 | IMPLANTABLE MEDICAL LEAD WITH MULTIPLE ELECTRODE CONFIGURATIONS - Medical leads having at least one segmented row of electrodes, as well as at least one ring electrode that extends substantially completely around the periphery of the lead, are described. The electrodes in a segmented row extend around only a portion of the periphery of the lead, rather than substantially around the entire periphery. The electrodes in a segmented row may be distributed at respective locations around the periphery of the lead and separated by insulating material. The ring electrodes and segmented rows are located at respective axial positions. For example, in some embodiments, a plurality of segmented rows, such as two rows having three electrodes each, are located between two ring electrodes. Such a lead may, for example, provide a variety of stimulation modalities because of localized stimulation capabilities. | 10-30-2008 |

20150133955 | MEDICAL LEADS HAVING A DISTAL BODY AND AN OPENLY COILED FILAR - Medical leads have one or more openly coiled filars and a distal body coupled to the openly coiled filars. The openly coiled filars provide a lead with compliance and elasticity while the distal body provides the firmness needed for placement and support of the electrodes. The openly coiled filars may transition to a linear distal portion that extends to the distal body, and the distal body may have proximal tines that fold proximally to become adjacent to the linear distal portion of the filars. The openly coiled filars may instead extend to the distal body and the proximal tines may be laterally arced to then fold against the lateral surface of the coiled filars. The tines may fold distally during explantation to allow the distal body to release and exit the body. | 05-14-2015 |

20130315253 | Lossless Connection Failover for Single Devices - The WAN optimization devices delay ACK until the ACK is actually received from the target while opening up the TCP window. When the ACK is received and forwarded, the TCP window is reduced in size. If there are mirrored WAN optimization devices, the original WAN optimization device sends the datagram across the WAN and at the same time sends the datagram to the mirroring WAN optimization device. When the mirroring WAN optimization device ACKs the mirrored datagram, the original WAN optimization device ACKs the host. When the ACK across the WAN is received, the mirroring WAN optimization device gets the ACK forwarded and deletes the mirrored datagram. On a loss of a device, the TCP connection transitions to the mirroring WAN optimization device, which closes the LAN TCP window and transmits all un-ACKed data. Then upon success the mirroring WAN optimization device reopens the LAN TCP window. | 11-28-2013 |
20130315260 | Flow-Based TCP - A system and method for sharing a WAN TCP tunnel between multiple flows without having head of the line blocking problem is disclosed. When a complete but out of order PDU is stuck behind an incomplete PDU in a TCP tunnel, the complete but out of order PDU is removed from the tunnel. To do that, first the boundaries of the PDUs of the different flows are preserved and the TCP receive window advertisement is increased. The receive window is opened when initially receiving out-of-order data. As out-of-order complete PDUs are pulled out of the receive queue, to address double counting, place holders are used in the receive queue to indicate data that was in the queue. As out-of-order data PDUs are pulled out of the queue the window advertisement is increased. This keeps the sending side from running out of TX window and stopping transmission of new data. | 11-28-2013 |
