Claims7
A method of treating a patient, comprising:
- placing a particle within a tissue of a patient, the particle comprising a polymer backbone bonded to a chemical species via a 1,2,3-triazole group, wherein the particle has a maximum dimension of at most 5,000 microns, and wherein the polymer backbone comprises polyvinyl alcohol.
A method of treating a patient, comprising:
- placing a particle within a tissue of a patient, the particle comprising:
- a first polymer backbone;
- a second polymer backbone;
- and
- a 1,2,3-triazole group,
- wherein the 1,2,3-triazole group is covalently bonded to the first and second polymer backbones to cross-link the first and second polymer backbones, and the particle has a maximum dimension of at most about 5,000 microns and the first and second polymer backbones comprises polyvinyl alcohol.
3 more elements
A method of treating a patient, comprising:
- placing a carrier fluid within a tissue of a patient, the carrier fluid comprising a plurality of particles, wherein at least some of the plurality of particles have a maximum dimension of at most about 5,000 microns and comprise a material comprising a first polymer backbone cross-linked to a second polymer backbone via a 1,2,3-triazole group and the first and second polymer backbones comprise polyvinyl alcohol.
