Abstract
A rough, bio-absorbable strand is provided. More specifically, a bio-absorbable strand having a central body and a rough or irregular outer surface capable of securing the placement of the strand inside a patient is provided. The strand has one or more radioactive seeds embedded in the central body of the strand. The rough outer surface of the strand may include one or more prongs, ridges, strips, grooves, or texture. Additionally, the strand may be capable of being dispensed from an implant needle.
Claims15
A bio-absorbable strand for securing the placement of radioactive seeds inside a patient, the strand comprising:
- an elongated body of bio-absorbable material, wherein the elongated body of the strand is positioned along a central longitudinal axis, the elongated body having one or more raised strips of bio-absorbable material of additional thickness rotationally positioned along the strand surface in a corkscrew manner, wherein the one or more raised strips of bio-absorbable material are at least partially connected to the strand surface such that parts of the one or more raised strips split off of the strand surface, projecting outward from the central longitudinal axis of the strand;
- a plurality of radioactive seeds imbedded in the body of the strand;
- and
- one or more bio-absorbable spacers imbedded between the plurality of radioactive seeds.
A rough bio-absorbable strand for securing the placement of radioactive seeds inside a tissue of a patient, the strand comprising:
- a central body of bio-absorbable material, wherein the central body is an elongated strand of bio-absorbable material having a central longitudinal axis;
- a rough outer surface of the central body, wherein the rough outer surface comprises one or more raised ridges of bio-absorbable material of additional thickness, each of the one or more raised ridges rotationally positioned on the strand surface extending lengthwise along the central longitudinal axis in a corkscrew manner from a proximal first end to a distal second end along the central body, wherein the one or more raised ridges are configured to secure the placement of the bio-absorbable structure inside the tissue of a patient;
- and
- a plurality of active elements implanted in the central body of the bio-absorbable structure, wherein the plurality of active elements contain therapeutic properties for treatment of a patient.
A rough bio-absorbable strand for securing the placement of radioactive seeds inside a tissue of a patient, the strand comprising:
- a central body of bio-absorbable material, wherein the central body is an elongated strand of bio-absorbable material having a central longitudinal axis;
- a rough outer surface of the central body, wherein the rough outer surface comprises one or more raised ridges of bio-absorbable material of additional thickness rotationally positioned on the strand surface along the central longitudinal axis in a corkscrew manner, wherein the one or more raised ridges are configured to secure the placement of the bio-absorbable structure inside the tissue of a patient, and wherein the one or more raised ridges of bio-absorbable material comprise at least two ridges that overlap at one or more points along the central longitudinal axis of the body of the strand, further adding thickness to the strand;
- and
- a plurality of active elements implanted in the central body of the bio-absorbable structure, wherein the plurality of active elements contain therapeutic properties for treatment of a patient.
