Bead Block™

Indications for Use

Bead Block™ microspheres are intended to be used for the embolization of hypervascular tumors, including uterine fibroids and arteriovenous malformations (AVMs).

Key Specifications

  • Preformed soft, deformable microspheres composed of a macromer derived from polyvinyl alcohol (PVA)
  • Fully polymerized microspheres are approximately 90-95% water
  • Compressible to approximately 30% by diameter
  • Dyed blue to aid in visualization in the delivery syringe
  • Can be delivered through typical microcatheters in the 1.5-5Fr range
  • Size ranges: 100-300µm, 300-500µm, 500-700µm, 700-900µm, 900-1200µm
  • Available in 1 ml or 2 ml quantities of beads with corresponding saline volumes (6 ml for 1 ml beads, 5 ml for 2 ml beads)
  • Certain configurations intended for Uterine Fibroid Embolization (UFE): EB1S709, EB1S912, EB2S709, EB2S912
  • Size calibrated spherical particles for embolization
  • Visualization of embolization process using radiographic imaging

Description

Bead Block™ is made up of preformed soft, deformable microspheres that occlude arteries for the purpose of blocking the blood flow to a target tissue, such as a fibroid or a cancerous tumor. 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 delivered through typical microcatheters in the 1.5-5Fr range.
