The VariSource Endometrial applicator which is the subject of this 510(k) is a component of the VariSource system. ## Device Story VariSource Endometrial Applicator is a component of the Varian VariSource Remote High Dose Rate (HDR) Afterloader system. The system uses an electromechanical device to enable remote-controlled delivery of a high-activity radionuclide source to internal or surface body locations for radiation brachytherapy. The applicator consists of a vaginal cylinder and irradiation tubes (one straight, two curved) made of stainless steel and polysulfone. It is operated by trained medical personnel in a clinical setting. The device facilitates precise source positioning for brachytherapy, allowing clinicians to deliver targeted radiation doses to treat specific anatomical sites, potentially improving therapeutic outcomes while minimizing radiation exposure to staff through remote operation. ## Clinical Evidence bench testing only ## Technological Characteristics Materials: Polysulfone (vaginal cylinder), Stainless Steel (irradiation tubes). Components: Vaginal cylinder, 3 irradiation tubes (1 straight, 2 curved). Fixation: Pivot assembly lock. Operation: Remote HDR afterloading system. Connectivity: Coupling catheter fittings. ## Regulatory Identification A remote controlled radionuclide applicator system is an electromechanical or pneumatic device intended to enable an operator to apply, by remote control, a radionuclide source into the body or to the surface of the body for radiation therapy. This generic type of device may include patient and equipment supports, component parts, treatment planning computer programs, and accessories. ## Predicate Devices - Mick Radio-Nuclear Instruments, Inc., Hilaris-Nori Endometrial Applicator ([K871216](/device/K871216.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
