Abstract
An isotope seeding system that controls the release of radioactive seeds for treatment of cancerous cells during cancer treatment procedures. The isotope seeding system comprises at least one seed that is chargeable with radioactive isotopes. At least one dissolvable web netting may alternatively be positioned about the at least one seed, and a seed deployment assembly is utilized for delivering the at least one seed, with or without the dissolvable web netting, into an organism's tissue, to surround cancerous cells. The seed deployment assembly includes an elongated cannula, a hub assembly and an obturator. The hub assembly includes an initial inner diameter at its proximal end and an operable length between the proximal end of the hub assembly and the proximal end of the cannula, the ratio of the initial inner diameter relative to the operable length being in the range of 0.075 to 0.175, to preclude against jamming of the at least one seed, with or without the at least one dissolvable web netting wrapped thereabout, within the hub assembly and/or to further preclude against inadvertent migration of such seeds from the web netting when such netting is utilized.
