Abstract
Official abstract text for this publication.
Implantable materials may be used in an iatrogenic site. Applications include radioopaque materials for fiducial marking.
First claim
Opening claim text (preview).
1 . A method for radiation therapy comprising introducing a hydrogel spacer at a site between a first tissue location and a second tissue location to increase a distance between the first tissue location and the second tissue location, with site being chosen to decrease radiation at the first tissue when the second tissue receives a dose of therapeutic radiation, wherein introducing the hydrogel spacer comprises placing one or more flowable synthetic precursors at the site that undergo a covalent crosslinking reaction to make, at the site, a covalently-crosslinked biodegradable hydrogel implant that has a covalently attached radiopaque agent. 2 . A method of making a space-occupying implant in a tissue, comprising injecting a tissue site with one or more flowable synthetic precursors in aqueous medium that undergo a covalent cross-linking reaction to make, in the site, a covalently-crosslinked biodegradable hydrogel implant that has a covalently attached radiopaque iodine agent.
