wherein the gateway is configured to convert the order quantity parameter in the contract-based unit to a converted order quantity parameter in the flow-based unit; and
wherein the gateway is configured to send a second message to buy or sell the tradeable object, wherein the second message includes the converted order quantity parameter in the flow-based unit.
2. The system of claim 1, wherein converting the quantity information in the flow-based unit to the converted quantity information in the contract-based unit is based on a predefined relationship.
3. The system of claim 1, wherein the flow-based unit is associated with a set of terms and conditions utilized by an exchange.
4. The system of claim 1, wherein the contract-based unit is associated with a set of terms and conditions preferred by a trader.
5. The system of claim 1, wherein the tradeable object includes any of the following products: oil, natural gas, or electric power.
6. The system of claim 1, wherein the flow-based unit includes any of the following units: bblday, MMBtusday, MMBtus, MWhrsday, or MWhrs.
7. The system of claim 1, wherein the second message is the first message modified to include the converted order quantity parameter in the flow-based unit instead of the order quantity parameter in the contract-based unit.
8. The system of claim 1, wherein the second message is sent to an exchange.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
Having described the invention, we claim:
1. An apparatus for eliminating dislodged thrombus in a blood vessel, said apparatus comprising:
a catheter having a plurality of infusion ports;
a filter attached to said catheter for trapping dislodged thrombus carried by blood flow in a blood vessel, said plurality of infusion ports being disposed within said filter and being operable to deliver a thrombolytic fluid to dissolve the dislodged thrombus trapped in said filter.
2. The apparatus of claim 1 wherein said plurality of infusion ports are spaced along an infusion section of said catheter in a helical pattern.
3. The apparatus of claim 1 wherein said plurality of infusion ports can deliver the thrombolytic fluid at a rate of up to 60 cchr.
4. The apparatus of claim 1 wherein said plurality of infusion ports vary in size and increase in diameter toward a distal end of said catheter.
5. The apparatus of claim 1 wherein said filter is radially expandable to stretch across the blood vessel and trap the dislodged thrombus.
6. The apparatus of claim 5 wherein said filter is self-expanding upon deployment in the blood vessel.
7. The apparatus of claim 5 wherein said filter comprises a mesh basket having a proximal end that has a relatively loose mesh to allow blood carrying the dislodged thrombus to enter said filter and a distal end that has a relatively tight mesh to trap the dislodged thrombus as the blood flows through said filter.
8. The apparatus of claim 5 wherein said filter has a distal end comprising a basket and a proximal end comprising support wires for supporting said basket.
9. The apparatus of claim 5 wherein said filter comprises at least one coil member that, when expanded, has a generally conical shape.
10. The apparatus of claim 1 further comprising a tubular member coaxially surrounding a portion of said catheter and being movable relative to said catheter.
11. The apparatus of claim 10 wherein a first end of said filter is attached to said tubular member and a second end of said filter is attached to said catheter.
12. The apparatus of claim 11 wherein said filter is radially expandable by moving said tubular member relative to said catheter.
13. An apparatus for eliminating dislodged thrombus in a blood vessel, said apparatus comprising:
relatively movable first and second tubular members, said first tubular member being partially disposed coaxially within said second tubular member, said first tubular member including a plurality of infusion ports for delivering a thrombolytic fluid; and
a filter member attached to said first and second tubular members, said filter member being radially expandable by relative movement between said first and second tubular members to stretch across the blood vessel and trap dislodged thrombus carried by blood flowing through the blood vessel;
said plurality of infusion ports being located within said filter member and oriented to direct the thrombolytic fluid against the dislodged thrombus trapped in said filter member and thereby dissolve the dislodged thrombus.
14. The apparatus of claim 13 wherein said plurality of infusion ports are spaced along an infusion section of said first tubular member in a helical pattern.
15. The apparatus of claim 13 wherein said plurality of infusion ports can deliver the thrombolytic fluid at a rate of up to 60 cchr.
16. The apparatus of claim 13 wherein said plurality of infusion ports vary in size and increase in diameter toward a distal end of said first tubular member.
17. The apparatus of claim 13 wherein said filter member comprises a mesh basket having a proximal end that has a relatively loose mesh to allow blood carrying the dislodged thrombus to enter said filter member and a distal end that has a relatively tight mesh to trap the dislodged thrombus as the blood flows through said filter.
18. The apparatus of claim 13 wherein said filter member has a distal end comprising a basket and a proximal end comprising support wires for supporting said basket.
19. The apparatus of claim 13 wherein said filter member comprises at least one coil member that, when expanded, has a generally conical shape.
20. A method for eliminating thrombus attached to a wall of a blood vessel, said method comprising the steps of:
inserting a radially expandable filter assembly into the blood vessel downstream from the thrombus, the filter assembly including a filter basket having a plurality of infusion ports disposed within the filter basket;
radially expanding the filter assembly to extend across the blood vessel;
dislodging the thrombus from the wall of the blood vessel;
trapping the dislodged thrombus in the filter basket; and
infusing a thrombolytic agent through the filter assembly and directing the flow of the thrombolytic agent through the plurality of infusion ports into the filter basket to dissolve the thrombus trapped in the filter basket.
