Embosphere Microspheres are indicated for use in the embolization of: - Hypervascular tumors, including symptomatic uterine fibroids - Prostatic arteries for symptomatic Benign Prostatic Hyperplasia (BPH) - Arteriovenous malformations - Blood vessels to occlude blood flow to control bleeding/hemorrhaging in the peripheral vasculature

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 appropriate size necessary for the vessel being embolized. The size ranges available are: • 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 (K181300). Embosphere Microspheres are permanent implantable devices and are designed for controlled, targeted embolization. All indications for Embosphere Microspheres; uterine arteries, arteriovenous malformations, hypervascular tumors and prostate arteries all involve arterial embolization. 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 interrupt artery blood flow to the targeted area. The device is intended for single use.

Embozene Color-Advanced Microspheres are intended for embolization of arteriovenous malformations and hypervascular tumors, including uterine fibroids (UFE) and hepatoma, and for embolization of prostatic arteries (PAE) for symptomatic benign prostatic hyperplasia (BPH). The device is not intended for neurovascular use.

Embozene Color-Advanced Microspheres (hereafter may be referenced as Embozene Microspheres or Embozene) are spherical, tightly calibrated, biocompatible, non-resorbable, hydrogel microspheres coated with an inorganic perfluorinated polymer shell (Polyzene-F). The microspheres are suspended in liquid and then injected into the bloodstream to permanently occlude blood vessels. They are used to stop bleeding when the underlying lesion is not likely to heal or block arteries supplying a tumor to cause tumor necrosis and/or shrinkage. Embozene Color-Advanced Microspheres are sterile, single use devices and are supplied in pre-filled 20 ml syringes containing 2ml of microspheres in approximately 7 ml of transport solution. The Embozene Microspheres are available in 40-1300 µm sizes.

Bead Block microspheres are intended to be used for the embolization of hypervascular tumours, including uterine fibroids (UFE) and arteriovenous malformations (AVMs). Bead Block microspheres are also intended for embolization of prostatic arteries (PAE) for symptomatic benign prostatic hyperplasia (BPH).

Bead Block, a permanent intravascular implant, is made up of preformed soft, compressible, biocompatible, hydrophilic, non-resorbable and precisely calibrated microspheres that occlude vessels for the purpose of blocking the blood flow to a target tissue. Bead Block compressible microspheres consist of a macromer derived from polyvinyl alcohol (PVA). The fully polymerized microsphere is approximately 90-95% water and is compressible to approximately 30% by diameter. Bead Block microspheres are dyed blue to aid in the visualization of the microspheres in the delivery syringe. The microspheres can be suspended in contrast agents and delivered through microcatheters to the target location. Bead Block is available in bead sizes from 100 – 1200µm and supplied sterile in 20ml syringes which contain 1 or 2 ml of beads suspended in 6 or 5 ml of phosphate buffered saline, respectively. The different bead sizes of the product are differentiated by differently colored labels and syringe end caps. Bead Block is provided as a single use, non-pyrogenic, sterile (steam sterilized) device.

The HydroPearl® Microspheres are intended for the embolization of arteriovenous malformations and hypervascular tumors, including uterine fibroids, and for embolization of prostatic arteries (PAE) for symptomatic benign prostatic hyperplasia (BPH).

The HydroPearl TM Microspheres are a pre-formed, compressible, precisely calibrated, spherical embolic agent consisting of a biocompatible hydrogel. The HydroPearl TM Microspheres are offered in a variety of diameters ranging from 75-1100µm and are provided in a sterile syringe pre-filled with microspheres in phosphate buffered saline. The pre- filled syringe is packaged in a sealed sterile dispenser tray. The HydroPearl TM Microspheres are delivered to the treatment site through a delivery catheter.

Embosphere Microspheres are indicated for use in the embolization of: • Hypervascular tumors, including symptomatic uterine fibroids • Prostatic arteries for symptomatic benign prostatic hyperplasia (BPH) • Arteriovenous malformations • Blood vessels to occlude blood flow to control bleeding/hemorrhaging in the peripheral vasculature (subject of this Traditional 510(k))

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.
