Particles and related methods are disclosed.

Particles

A particle includes a ferromagnetic material, a radiopaque material, and/or an MRI-visible material.

Embolization

Polymer insulators and methods of using polymer insulators are disclosed. In some embodiments, a method includes separating a first portion of a subject's tissue from a second portion of the subject's tissue so that there is a space between the first and second portions of tissue. Deionized water, a buffered saline solution, liquid polymers, gels, particles, foams, and/or gases are disposed between the first and second portions of tissue, and the first portion of tissue is exposed to energy to treat the first portion of tissue.

Tissue-treatment methods

Ferromagnetic particles and methods are disclosed.

Ferromagnetic particles and methods

Embolization, as well as related particles and methods, are described.

A drug delivery particle including a reservoir region having primarily large pores and a metering region. The particle can be highly spherical.

Drug delivery particle

A particle with a diameter of at most about 3,000 microns has an internal pressure of at least about 1.1 atmospheres at a temperature of less than about 25&#xb0; C.

A composition includes a plurality of particles. At least some of the plurality of particles include cross-linked polyvinyl alcohol and have a diameter of about 500 microns or less. The particles have a first average pore size in an interior region, and a second average pore size at a surface region. The first average pore size being greater than the second average pore size. The composition also includes a carrier fluid. The plurality of particles being in the carrier fluid.

Porous polymeric particle comprising polyvinyl alcohol and having interior to surface porosity-gradient

Particles and related methods are disclosed. In some embodiments, a method of making particles can include forming a stream of a mixture including first and second materials, exposing the stream to a vibration, and treating the stream to form particles. The vibration can have, for example, a sinusoidal, triangular, and/or sawtooth waveform.
