Abstract: A system for delivering an implant device to a vascular site in a patient a delivery pusher apparatus, an implant device detachably connected to the delivery pusher apparatus by a tether having a distal end connected to a proximal end of the implant device, wherein the tether is substantially non-tensioned when connecting the implant device to the delivery pusher, and an electrical heating element configured coaxially around at least a portion of the tether, wherein heat generated by the heating element severs the tether at a point near the proximal end of the implant device.

Abstract: A nozzle assembly for use in cleaning tubular members of a tube-type heat exchange having a protective coating. A metal nozzle core for communicating with a source of high-pressure water is covered at an exterior portion thereof with a plastic nozzle sleeve for engagement with the heat exchanger. A circumferential ridge of the nozzle core disposed in a circumferential groove of the nozzle sleeve prevents separation of the nozzle core and nozzle sleeve during use.

Abstract: An indexed mutual fund management system and a method for managing such a fund calculate, based on a fund time T, a value of fixed income assets and a value of derivative assets such that the sum of the value of fixed income assets and the value of derivative assets equals an initial mutual fund principal amount at a mutual fund closing time, calculate a hedging strategy over the fund time based on the value of derivative assets related to an index, transmit one or more orders for investment of a portion of the fund principal equal to the value of fixed income assets, and transmit one or more orders for investment of a portion of the fund principal equal to the value of derivative assets according to the hedging strategy. The system and method may calculate a cap for the indexed mutual fund based on the value of derivative assets related to an index, in which case the hedging strategy may be calculated over the fund time based on the cap.

Abstract: An indexed guaranteed investment contract (GIC) system and a method for managing an indexed GIC calculate, based on a contract time T, a value of fixed income assets and a value of derivative assets such that the sum of the value of fixed income assets and the value of derivative assets equals an initial contract principal amount at a contract closing time, calculate a hedging strategy over the contract time, transmit one or more orders for investment of a portion of the contract principal equal to the value of fixed income assets, and transmit one or more orders for investment of a portion of the contract principal equal to the value of derivative assets according to the hedging strategy. The system and method may calculate a cap for the indexed GIC based on the value of derivative assets related to an index, in which case the hedging strategy may be calculated over the contract time based on the cap.
