Abstract
Exemplary brachytherapy applicators may include an interstitial tube having a body with a proximal end and a distal end and a central conduit extending from the distal end of the body, wherein the central conduit includes a proximal opening, a distal opening, and a channel extending from the proximal opening to the distal opening, and wherein the proximal opening is offset from an axis of the body. The proximal opening may be configured to fluidly connect to a brachytherapy guide tube, and the channel of the central conduit may be dimensioned to receive at least one of a needle or a catheter therethrough.
Claims21
A brachytherapy applicator comprising:
- an interstitial tube, wherein the interstitial tube includes:
- a body having a proximal end and a distal end;
- a central conduit extending from the distal end of the body, wherein the central conduit includes a proximal opening, a distal opening located at a distalmost end of the brachytherapy applicator, and a channel extending from the proximal opening to the distal opening, and wherein the proximal opening is offset vertically from an axis of the body;
- and
- at least one ovoid tube coupled to the interstitial tube and offset peripherally from the axis of the body, wherein the at least one ovoid tube is configured to support an ovoid at a distal end thereof;
- wherein the proximal opening is configured to fluidly connect to a brachytherapy guide tube, and wherein the central conduit is configured to receive at least one of a needle or a catheter through the brachytherapy guide tube and the channel, bypassing the body.
A brachytherapy applicator comprising:
- an interstitial tube including:
- a body having a proximal end and a distal end;
- a joint located at a distal region of the body, wherein the joint has a proximal surface having an opening for coupling to a brachytherapy guide tube, wherein the opening is offset from an axis of the body;
- and
- a central conduit extending distally from the joint, wherein the central conduit has a channel therethrough that fluidly connects with the opening in the joint and extends through a distal end of the central conduit so that the distal end of the central conduit is open, wherein the distal end of the central conduit is located at a distalmost end of the brachytherapy applicator;
- a first ovoid tube having a first ovoid located at a distal end of the first ovoid tube;
- and
- a second ovoid tube having a second ovoid located at a distal end of the second ovoid tube;
- wherein the first ovoid and the second ovoid cooperatively form a generally rectangular surface aligned around the central conduit when the first ovoid tube and the second ovoid tube are connected to the interstitial tube, and wherein the central conduit is configured to receive at least one of a needle or a catheter through the brachytherapy guide tube and the channel, bypassing the body.
A kit for forming a modular brachytherapy applicator, the kit comprising:
- an interstitial tube having:
- a body having a proximal end and a distal end;
- and
- a central conduit extending from the distal end of the body, wherein the central conduit includes a proximal opening, a distal opening located at a distalmost end of the brachytherapy applicator, and a channel extending from the proximal opening to the distal opening, and wherein a proximal end of the central conduit where the proximal opening is located is offset from an axis of the body;
- a first ovoid tube;
- a first ovoid;
- a second ovoid tube;
- and
- a second ovoid;
- wherein the proximal opening is configured to fluidly connect to a brachytherapy guide tube, and wherein the central conduit is configured to receive at least one of a needle or a catheter through the brachytherapy guide tube and the channel, bypassing the body.
