Isotope seeding system that releases radioactive seeds for treatment of cancerous cells
First Claim
1. An isotope seeding system that controls the release of radioactive seeds for treatment of cancerous cells to preclude against jamming and inadvertent migration of said radioactive seeds curing cancer treatment procedures, said system comprising:
- at least one seed that is chargeable with radioactive isotopes;
a seed deployment assembly for locating and delivering said at least one seed into the tissue of an organism, proximate to said cancerous cells;
said deployment assembly including an elongated cannula having a proximal and a distal end, said distal end opposite said proximal end and a conduit positioned therebetween;
a hub assembly attached to the elongated cannula at the proximal end of said cannula, the hub assembly including a proximal and distal end, and an interior region, said distal end of said hub assembly operably associated with the proximal end of said elongated cannula for staging and directing said at least one seed through said elongated cannula from said cannula proximal end to said cannula distal end and, in turn, into said tissue at a desired location proximate said cancerous cells;
an obturator for telescopic projection of said at least one seed through both said hub assembly and said elongated cannula; and
said hub assembly having an initial inner diameter at its proximal end and an operable length between said proximal end of said hub assembly and said proximal end of said cannula, said ratio of said initial inner diameter at the proximal end of said hub assembly, relative to the operable length of said hub assembly, being in the range of 0.075 to 0.175, to ensure against the inadvertent migration and jamming of said at least one seed in said hub assembly; and
the interior region of said hub assembly including a first substantially conical section having a length and a second substantially conical section having a length, the length of the first conical section being at least 50% of the combined length of the first and second conical sections.

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.
