The device is a physical medical device (microspheres) used in embolization procedures, not a software-only device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
- Device Function: The Embosphere Microspheres are implantable devices used for embolization. This is a procedure performed within the body to block blood vessels.
- Intended Use: The intended uses listed (embolization of tumors, fibroids, BPH, AVMs, and peripheral vasculature) all involve a therapeutic intervention performed directly on the patient's circulatory system.
- Device Description: The description details the physical characteristics of the microspheres and how they are delivered into the body.
- Procedure: The description of the procedure clearly outlines an interventional radiological procedure performed on the patient.
The device is a therapeutic medical device used for embolization, not a diagnostic device that analyzes samples outside the body.

Device Description
Embosphere Microspheres are small, compressible, hydrophilic, biocompatible spheres made of acrylic polymer and porcine-derived gelatin. The microspheres are packaged in 0.9% saline and are provided sterile and non-pyrogenic in a vial or in a syringe. The product is provided in seven size ranges to allow physicians to choose the calibration necessary for the vessel being embolized: 50-100 microns, 40-120 microns, 100-300 microns, 300-500 microns, 500-700 microns, 700-900 microns, 900-1200 microns.
The principles of operation for the subject device Embosphere Microspheres are the same as the predicate device Embosphere Microspheres (K021397) and reference devices Embosphere Microspheres (K991549, DEN160040). Embosphere Microspheres are permanent implantable devices and are designed for controlled, targeted embolizations. Embolization of uterine fibroids, arteriovenous malformations, hypervascular tumors and benign prostatic hyperplasia involve an embolization of the arteries supplying those areas. The procedure of arterial embolization is similar for all arteries. Appropriately sized microspheres for target vessel occlusion are chosen by the trained interventional radiologist. The delivery procedure involves arterial access through an artery, using a guidewire and microcatheter under fluoroscopic guidance. Once the catheter tip is placed in the artery(ies) supplying the targeted tissue, Embosphere Microspheres mixed with a non-ionic contrast agent are delivered in a controlled manner under visualization to occlude the feeding vessel(s) to stop blood flow to the targeted area. The device is intended for single use.

Device Description
The principles of operation for the subject device Embosphere Microspheres are the same as the predicate device Embosphere Microspheres (K021397) and reference devices Embosphere Microspheres (K991549, DEN160040). Embosphere Microspheres are permanent implantable devices and are designed for controlled, targeted embolizations for Embosphere Microsphere Microspheres involve arterial embolization; embolization of uterine fibroids, arteriovenous malformations, hypervascular tumors and benign prostatic hyperplasia involve an embolization of the arteries supplying those areas. The procedure of arterial embolization is similar for all arteries. Appropriately sized microspheres for target vessel occlusion are chosen by the trained interventional radiologist. The delivery procedure involves arterial access through an artery, using a quidewire and microcatheter under fluoroscopic guidance. Once the catheter tip is placed in the artery(ies) supplying the targeted tissue Embosphere Microspheres mixed with a non-ionic contrast agent are delivered in a controlled manner under visualization to occlude the feeding vessel(s) to stop blood flow to the targeted area.

No performance standards have been established under Section 514 of the Food, Drug and Cosmetic Act for these devices. However, vascular and neurovascular embolization devices are subject to the special controls specified in "Guidance for Industry and FDA Staff - Class II Special Controls Guidance Document: Vascular and Neurovascular Embolization Devices", issued on December 29, 2004. In addition, the subject device follows the FDA Draft Guidance on "Medical Devices Containing Materials Derived from Animal Sources (Except for In Vitro Diagnostic Devices)", issued on January 23, 2014.
Non-clinical performance testing conducted on the predicate device includes:
- · Chemical analysis
- · Size range
- Catheter compatibility
- Packaging performance
- · Shelf Life
- · Sterilitv
- · Biocompatibility
Biocompatibility evaluation was performed in accordance with ISO 10993-1:2009 for permanent implants in contact with blood for the predicate device Embosphere Microspheres (K021397) and the reference devices Embosphere Microspheres (K991549, DEN160040), and is being adopted for this subject device based upon the fact that all devices are made from the same materials using the same manufacturing and sterilization processes.
Safety & Performance Tests
No new testing was performed since predicate device Embosphere Microspheres (K021397) / reference devices Embosphere Microspheres (K991549. DEN160040), and subject device Embosphere Microspheres have identical technological characteristics, manufacturing, processing and sterilization.
Clinical data from the literature were reviewed on the use of Embosphere Microspheres for embolization of blood vessels to occlude blood flow to control bleeding / hemorrhaging in the peripheral vasculature. The retrieved clinical data consisted of 40 publications from 2000 to 2018, including eight prospective trials and thirty-two retrospective trials. The total number of patients treated with Embosphere Microspheres was 662 (at least). The majority of patients were adults of both genders. Some publications listed age ranges below adult (from 1 to 17 years).
The extensive clinical data provide relevant information about the safety and effectiveness of the subject Embosphere Microspheres in the proposed indication for use. Embolization of arteries with Embosphere was found to be an effective method to control bleeding / hemorrhaging in the peripheral vasculature, with a low complication rate.
Adverse events that were found related to the procedure are mostly complications related to catheterization, post-embolization syndrome and non- targeted embolization. The raised events found are addressed in the predicate device Embosphere Microspheres (K021397) and the reference devices Embosphere Microspheres (K991549, DEN160040) IFU as warnings or potential complications.
The proposed indication for use does not raise a safety or effectiveness issue that was not raised by the predicate device, or have the potential to significantly increase a safety or effectiveness concern raised by the predicate device. The
7
function of both the subject device and predicate device (K021397) is to occlude blood vessel(s) in order to stop blood flow to a targeted area, which is the clinical endpoint for both devices. The safety and effectiveness of the device are related to size, shape, compressibility and biocompatibility for both general and specific indications. These characteristics do not change from the predicate to the subject Embosphere Microspheres.
Based on the same intended use (other than the requested change that is the objective of this submission), design, fundamental scientific technological Summary of characteristics, fundamental operational characteristics and safety and Substantial performance testing, the BioSphere Medical subject Embosphere Microspheres device meets the requirements that are considered essential for its intended use Equivalence and is substantially equivalent to the predicate device Embosphere Microspheres (K021397).
