• Applicant: Nucletron Corp.
• Product Code: JAQ · Radiology
• Decision Date: Aug 18, 2004
• Decision: SESE
• Submission Type: Special
• Regulation: 21 CFR 892.5700
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The MicroSelectron PDR is intended to enable an operator to apply, by remote control, a radionuclide source into the body (including Interstitial, Intracavitary, Intraluminal, Bronchial, or intra-operative) or to the surface of the body for radiation therapy.

Device Story

MicroSelectron PDR is a remote-controlled radionuclide applicator system for radiation therapy. It functions as an afterloader, delivering radiation sources into the body or onto the surface. The system utilizes a PC-based workstation running Windows XP, which manages treatment scheduling and PDR (Pulsed Dose Rate) workflows. Treatment plans are transferred from external radiotherapy planning software via LAN file transfer. The device incorporates an RCU (Remote Control Unit), NSD (Nucletron Source Driver), and a radiation status indicator. It is operated by clinical staff in a radiotherapy setting. The system enables precise, remote delivery of radiation, reducing radiation exposure to clinicians while facilitating targeted treatment for various anatomical sites. It builds upon the MicroSelectron HDR platform, adding specific PDR functionality and components from previously cleared Nucletron devices.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Remote-controlled radionuclide applicator system. PC-based workstation running Windows XP. Includes RCU, NSD, and radiation status indicator. Connectivity via LAN for treatment plan file transfer. Software-controlled workflow for PDR procedures.

Indications for Use

Indicated for patients requiring radiation therapy via remote-controlled radionuclide source application, including interstitial, intracavitary, intraluminal, bronchial, intra-operative, or surface body applications.

Regulatory Classification

Identification

Troatment Console Software by file transfer. Connection to a LAN is planning soltware to the Transfer of Treatment Plan Files. It is the same as in the predicate only for the parpose of I he Treatment Console Software Console Software from radiotherapy treatment planning software running on a separate computer.

The radiotherapy treatment planning software is not part of this 510(k) submission. Applicators The Tadiotherapy « Cathere for microSelectron-HDR (V2) are also applicable for the aria Transfer Tubes as available for Information of the ended as a modality to the Nucletron microSelectron Afterloader system.

The PC based Afterloader workstation is the current TCS workstation, but ported to from a rrie TO based Alteriouse woment of the PC based Afterloader workstation comes with functionality to support PDR procedures (i.e. Scheduling of treatments).

The modifications to the previously cleared device K953946 are:

- Addition of RCU and NSD previously cleared device K902533 .
- Addition of Radiation Status Indicator .
- Changes to TCS to enable the PDR workflow .
- Addition of Smoothbase, part of previously cleared device K031158 .

The software runs on a PC with a Windows XP platform.

#### Intended use:

The modified device has the same intended use as the legally marketed predicate device cited:

The MicroSelectron PDR is intended to enable an operator to apply, by remote control, a r ric Millorolooron PB the body (including Interstitial, Intracavitary, Intraluminal, Bronchial, radionablias obarbs into intra-operative) or to the surface of the body for radiation therapy.

#### Summary of technological considerations:

MicroSelectron PDR is substantially equivalent to the cleared predicate device, microSelectron HDR, 510(k)#: K953946.
