AI Technical Summary

Problems solved by technology

Variations in patient anatomy can make some conventional brachytherapy delivery devices unwieldy or unsuitable for accurately delivering a pre-planned dose distribution within the subject
Additionally, some conventional applicators can be substantially rigid once assembled and can cause patient discomfort
In particular, some gynecological brachytherapy applicators may cause pain associated with the subject's vaginal introitus and / or may be too large for some subjects
Traditional brachytherapy delivery devices may not be suitable - and therefore may not be effective - to ideally target women with large anatomical deviations, such as those without a uterus (eg, post-hysterectomy)
In this group of patients, traditional brachytherapy delivery devices may provide less effective treatment, or a medical professional may manually place the needle to release the radioactive source
Traditional modular brachytherapy applicators can be more time consuming to assemble, with some parts requiring separate screws and / or tools to attach different parts

Abstract

Embodiments of the disclosure may be drawn to brachytherapy applicators. Exemplary 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 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 there through.

Description

[0001] Citations to related applications [0002] This application claims the benefit of priority of U.S. Provisional Application No. 62 / 824,484, filed March 27, 2019, and U.S. Provisional Application No. 62 / 900,030, filed September 13, 2019, each of which is in its entirety Incorporated herein by reference. technical field [0003] Various embodiments of the present disclosure relate generally to medical devices for brachytherapy. More particularly, embodiments of the present disclosure relate to brachytherapy applicators, and particularly gynecological applicators. Background technique [0004] Brachytherapy can be used to treat cancerous tissue, such as tumors, and involves placing a radiation source relative to the area of ​​the subject (eg, patient) to be treated. Brachytherapy applicators may be used to facilitate accurate placement of radiation sources, eg, interstitial or intracavity. Variations in patient anatomy can make some conventional brachytherapy delivery ...
