Abstract
A chemical absorber to absorb and release compounds includes a porous scaffold of lattices, modified surfaces of the scaffold, wherein the modification is selected based upon an ability to bond with or release a particular compound, and a center hole in the scaffold to accommodate a guide wire.
Claims23
A chemical absorber to absorb and release compounds, comprising:
- a porous scaffold of lattices;
- a surface modification on at least one surface of the lattices, wherein the surface modification is selected based upon an ability to one of either bond with, or release, a particular compound;
- and
- a center hole in the scaffold to accommodate a guide wire.
The chemical absorber as claimed in claimed 1, wherein the surface modification comprises functional groups added to the at least one surface of the lattices.
A method of manufacturing a chemical absorber, comprising:
- forming a three-dimensional porous scaffold of lattices having a center hole;
- and
- modifying at least one surface of at least one of the scaffold and lattices to introduce functional groups, wherein the functional groups are selected based upon an ability to bond with a particular compound.
A method of introducing a chemical absorber into a body, comprising:
- inserting a guide wire through a central hole in the chemical absorber;
- attaching the chemical absorber to the guide wire;
- inserting the chemical absorber into an introducer sheath;
- inserting the introducing sheath into a blood vessel of the body;
- and
- placing the chemical absorber into a vein from which blood from a tumor is drained.
