The device description clearly outlines multiple hardware components (irradiation unit, imager loader system, breast immobilization system) in addition to the treatment planning system (which likely includes software). The device is a physical teletherapy system, not solely software.
Based on the provided information, the GammaPod™ device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the GammaPod™ is a "teletherapy device intended for use in the noninvasive stereotactic delivery of a radiation dose to a partial volume of the breast". This describes a therapeutic device that delivers radiation to a patient's body.
- Device Description: The description reinforces this by explaining it uses "rotating, multi-source Cobalt-60 gamma-ray emitting sources to noninvasively deliver a focal dose of radiation". This is a description of a radiation therapy device.
- IVD Definition: In vitro diagnostics (IVDs) are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. The GammaPod™ does not perform any such tests on biological samples.
The GammaPod™ is a medical device used for treatment, specifically radiation therapy, not for diagnostic testing of biological samples.

Device Description
The GammaPod™ is a teletherapy device that uses rotating, multi-source Cobalt-60 gamma-ray emitting sources to noninvasively deliver a focal dose of radiation to a partial volume of a human breast of a patient in the prone position while sparing the surrounding normal tissues and structures.
The GammaPod system contains 4 main components:
i. GammaPod irradiation unit. The GammaPod irradiation unit consists of a round "pod" containing a hemispherical source carrier that holds multiple Co® sources, a hemispherical dynamically changing collimator system (inside and concentric to the source carrier), a hemi-elliptical-sphere treatment space (inside the collimator) within which the breast is positioned for treatment and a treatment patient loader that lifts and rotates a patient positioned on a treatment couch from the standing to prone position above the round "pod". The couch contains a portal within which the breast immobilization cup is affixed. The irradiation unit is controlled by a computerized treatment control system.
ii. Imager loader system. An imaging couch design and operation, which are similar to the treatment couch, are intended to make the imaging geometry identical to the treatment geometry. A patient is lifted and rotated from a standing position to prone position for imaging while wearing a breast immobilization device, which is affixed through a portal in the imaqing couch.
iii. Breast immobilization system. A vacuum-assisted breast cup is designed to reproducibly hold the breast in place and provide an accurate reference frame to match the tumor with the coordinate system of the irradiation unit. The cup consists of a rigid reusable outer cup with an imbedded stereotactic frame and a thin inner cup joined together by a silicone flange at the chest side. A mild negative pressure is applied between the inner and outer cups causing the skin of the breast to press against the inner cup, securing the breast in place.
iv. Treatment planning system. A treatment planning system is designed specifically for planning breast radiotherapy using the GammaPod by:
a) Placing the breast images within the stereotactic localization frame coordinate system through an image registration process;
b) Optimizing a dynamic and deliverable trajectory of the focal spots of different sizes to realize the prescribed dose to the target volume while minimizing radiation exposure to the surrounding tissues and structures; and
c) Ensuring accurate dose calculation of the optimized plan and providing dosimetric indices for review.

V. INTENDED USE
GammaPod™ is a teletherapy device intended for use in the noninvasive stereotactic delivery of a radiation dose to a partial volume of the breast in conjunction with breast conserving treatment.
VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS TO THE PREDICATE DEVICE
The GammaPod physical design is fundamentally the same as the predicate Device, the Rotating Gamma System - Gamma ART-6000. which uses the same means of achieving a highly focused radiation dose at the isocenter (i.e., using multiple rotating Cobalt-60 sources to focus the radiation at the common isocenter). As compared with the Predicate Device, the GammaPod system has the same intended use, uses the same radioisotope, applies the same operating principle, has similar technical characteristics and meets similar performance specifications. Both the GammaPod and the Predicate Device meet the same sets of regulations and standards.
The key difference between the GammaPod and the Predicate Device is in the site of treatment. While the GammaPod is physically designed specifically for delivering a focal dose of radiation to a partial volume of the human breast, the Predicate Device is designed to treat intracranial lesions. Therefore, the orientation of the treatment space is different.

VIII. SUMMARY OF NONCLINICAL TESTS
A Hazard Analysis was conducted for GammaPod according to ISO 14971 and methods for preventing such hazards were identified and verified. Verification and validation of the control system software and treatment planning system software were conducted in house in accordance to the established Verification and Validation (V&V) Protocols within FDA Software Validation guidance.
Radiation tests including radiation safety measures and radiation dosimetric accuracy tests were conducted to meet the requirements of the NRC and IEC 60601-2-11. The measured radiation leakage profile of the GammaPod is far below the recommended levels of IEC 60601-2-11 and NCRP Report #102 as shown in the Radiation Test Report.
Tests for mechanical safety and mechanical accuracy were also conducted in house. Additionally, a certified laboratory has evaluated GammaPod and certified its compliance with IEC 60601-1:2012 Edition 3.1 Medical electrical equipment - Part 1: General requirements for basic safety and essential performance. EMC testing was conducted by the same lab showing that the GammaPod meets IEC 60601-1-2:2007 Edition 3.0 Medical electrical equipment- Part 1-2: General requirements for safety -Collateral standard: Electromagnetic compatibility - Requirements and tests.
Bio-compatibility has been verified to the requirements of ISO 10993 by a certified laboratory for the breast cup and the silicone flange.
Device performance was tested against a set of functional specifications in an environment that simulated, to the extent practically possible, the actual operating environment. Validation testing demonstrated that the device is as safe and effective as the predicate device.
These tests have demonstrated that the GammaPod system has met its specifications, demonstrated substantially equivalent performance to the predicate device and is suitable for its intended use.

IX. SUMMARY OF CLINICAL TESTS
Clinical testing was conducted through an FDA-approved Phase I clinical trial under IDE No. G120054. Seventeen (17) patients were enrolled from March, 2016 to August, 2017 according to the approved IDE clinical protocol. For each patient, the feasibility of using the GammaPod to deliver a focal dose of radiation to a partial volume of the breast while keeping the dose to other surrounding tissues and organs within specified limits was evaluated. For each patient, the safety and dosimetric accuracy were also evaluated and the results demonstrated that the GammaPod system can safely deliver the prescribed doses as intended.
X. CONCLUSIONS DRAWN FROM NONCLINICAL AND CLINICAL TESTS
As compared with the Gamma ART-6000, the GammaPod system has the same intended use, uses the same radioisotope, applies the same operating principle, has similar technical characteristics and meets similar performance specifications. Both the GammaPod and the Predicate Device meet the same sets of regulations and standards. The mechanical design differences between the GammaPod and the Predicate Device do not raise any new or different issues of safety or effectiveness. The GammaPod is therefore substantially equivalent to the Predicate Device.
