Process for in vivo treatment of specific biological targets in bodily fluids
View Patent ↗A process for treating biological targets in a fluid of a biological organism, including introducing a fluid comprising a biological target to an assembly comprising an inlet connected to receive the fluid and an outlet connected to pass the fluid from the assembly, wherein the assembly comprises a flow chamber for conveying a flow of the fluid, and a capture zone comprising a target-specific binding agent, wherein during flow of the fluid through the flow chamber, the biological target undergoes flux rolling along the target-specific binding agent.
1. A process for treating a stem cell comprising the steps of:
introducing a fluid that includes at least one stem cell to an inlet of an assembly, the assembly comprising a flow chamber with a cross-sectional dimension less than 150 microns for conveying the fluid through the assembly, the flow chamber having a capture zone comprising a stem cell-specific binding agent;
permitting the fluid to pass through the flow chamber wherein the stem cell undergoes flux rolling along the stem cell-specific binding agent.
2. A process for treating a stem cell in the blood of an organism comprising the steps of:
placing an assembly in fluid communication with a vein or artery of an organism, the assembly comprising a flow chamber with a cross-sectional dimension less than 150 microns for conveying a first portion of blood through the assembly, the flow chamber having a capture zone comprising a stem cell-specific binding agent;
permitting blood to pass through the flow chamber, wherein during flow of the blood through the flow chamber, the stem cell undergoes flux rolling along the stem cell-specific binding agent.
3. The process as recited in claim 2 , wherein the stem cell-specific binding agent is a peptide or protein.
4. The process as recited in claim 2 , wherein the stem cell-specific binding agent comprises E-selectin, P-selectin, ICAM-1, cadherin-11 or a combination thereof.
5. The process as recited in claim 2 , wherein the assembly further comprises a bypass chamber for conveying a second portion of blood through the assembly without passing the second portion through the flow chamber.
6. The process as recited in claim 2 , wherein the assembly comprises a stent, catheter, cannula, capsule, patch, wire, infusion sleeve, fiber, shunt or graft.
7. The process as recited in claim 2 , wherein the assembly is formed from a natural or synthetic polymer, fiber, diatomaceous earth, glass, metal, colloid or plastic.
8. The process as recited in claim 2 , wherein the stem cell-specific binding agent is immobilized to a surface of the capture zone.
9. The process as recited in claim 2 , wherein the stem cell-specific binding agent is adsorbed or covalently bonded to a surface of the capture zone.
10. The process as recited in claim 2 , wherein after flux rolling of the stem cell along the stem cell-specific binding agent, the stem cell is removed from the capture zone and collected.
11. The process as recited in claim 2 , wherein the flow chamber includes an access port.
12. A process for treating a cancer cell in the blood of an organism comprising the steps of:
implanting an assembly in an organism such that the assembly is in fluid communication with a vein or artery of the organism, the assembly comprising a flow chamber with a cross-sectional dimension less than 150 microns for conveying a first portion of blood through the assembly, the flow chamber having a capture zone comprising a cancer cell-specific binding agent;
permitting blood to pass through the flow chamber, wherein during flow of the blood through the flow chamber, the cancer cell undergoes flux rolling along the cancer cell-specific binding agent.
13. The process as recited in claim 12 , wherein the assembly further comprises a bypass chamber for conveying a second portion of blood through the assembly without passing the second portion through the flow chamber.
14. The process as recited in claim 12 , wherein the capture zone further comprises an anti-proliferative agent that is adsorbed or covalently bonded to a surface of the capture zone.
15. The process as recited in claim 12 , wherein the cancer cell-specific binding agent comprises E-selectin, P-selectin, ICAM-1, cadherin-11 or a combination thereof.
16. The process as recited in claim 12 , further comprising a second assembly which is substantially identical to the first assembly, the first and second assemblies being in fluid communication such that the blood passes through each assembly in series.
