Product Specifications and Sizes

DC Bead LUMI™ are precisely calibrated, radiopaque, biocompatible, nonresorbable hydrogel beads. The beads are produced from polyvinyl alcohol and contain a covalently bound radiopaque moiety.

DC Bead LUMI™ are manufactured to be inherently radiopaque and visible under imaging (Computed Tomography [CT], Cone Beam Computed Tomography [CBCT] and Fluoroscopy). DC Bead LUMI™ are available in two size ranges:

SizeLabel Color
70-150µmBlack

Presentation

  • DC Bead LUMI™ are offered in a prefilled 10ml glass vial, stopper sealed by an aluminum cap with a color-coded lid.
  • Each vial contains approximately 2ml of product in sterile phosphate buffered saline. The total volume of DC Bead LUMI™ and sterile physiological saline is approximately 8ml. 
  • Each package contains a sterile 20mm ViaLok™ Vented Vial Access Device for removal of DC Bead LUMI™ from the vial. 
  • Each vial of DC Bead LUMI™ is intended for single patient use only. Do not re-sterilize. Discard any unused material.

 

AttributeDC Bead LUMI
RadiopacityDeveloped from DC Bead chemistry with a covalently bonded iodine to offer long term radiopacity.
ColorPale golden color
DensityDensity - 1.30; Iodine content makes DC Bead LUMI a little denser than DC Bead
SuspentionDue to DC Bead LUMI being denser, it shoudl be delivered in pure contrast to endure a good suspension.
Distal PenetrationIn-vitro testing of DC Bead LUMI indicates that the distal penetration is equivalen to sizes of DC Bead.
Storage & Shelf Life

Unopened: 24 month shelf life if stored at room temperature.

Opened: Once opened, should be used within 24 hours if refrigerated or 4 hours if at room temperature.

PackagingNew packaging containing vials with colored stoppers, transfer device. Each vial contains 2ml of beads

Contrast Agents

DC Bead LUMI must be suspended in soluble iodinated contrast (a minimum of 20ml per vial) to achieve effective delivery through microcatheters and to aid visualization during administration. Only pure contrast (i.e. undiluted) should be used. The DC Bead LUMI IFU recommends using contrast agents Omnipaque 350 (Iohexol 350) and Iomeron 400 (Iomeprol 400). Based on post-approval early experience, please note that Visipaque provides an even better (long and stable) suspension. DC Bead LUMI is visible on X-ray as the beads accumulate in the vessel and the contrast clears.

Recommended Catheters and Contrast Agents for application with DC Bead LUMI

Once prepared, DC Bead LUMI has been tested and shown to be successfully delivered using the combinations of microspheres size, contrast medium and microcatheters shown in the table below.
DC Bead LUMIRecommended Catheter
(Internal Diameter)
70-150μm
≥2.0Fr
(0.483mm/0.019in)
Recommended Contrast Agents: Omnipaque 350 (lohexol), Iomeron 400 (Iomeprol), Optiray 350 (Ioversol), Oxilan 350 (Ioxilan), Isovue 370 (Iopamidol), Ultravist 350 (Iopromide).
  • Other contrast agents have not been tested in conjunction with DC Bead LUMI.
  • Isovue 300 (Iopamidol) has been tested and is not recommended for use due to the inadequate suspension times. Contrast agents of a similar or lower viscosity at 20° C should not be used with DC Bead LUMI.

 

Radiopacity and Visualization

DC Bead LUMI is radiopaque from the proven core chemistry used in DC Bead with the blue dye replaced by a covalently bonded iodine to offer radiopacity. The radiopacity is integral to the bead and will not degrade, so DC Bead LUMI will be visible on imaging at long-term follow-up.

DC Bead LUMI is visible under x-ray imaging as they accumulate in the embolized vessels. It can be directly visualized as the delivery contrast agent washes out. Best visualization is achieved after administration using X-ray single shot technique (also referred to as X-ray snap shot). Cone beam CT (CBCT) can also be used to visualize the beads accumulated in the vessels with multi-planar reconstructions providing 3D spatial bead location and vessel connectivity.

DC Bead LUMI is easily visualized with CT. Early experience images from various different tumor types, show discrete embolized vessels where DC Bead LUMI is present with no significant streak artefacts nor masking of adjacent tissue unlike commonly seen following lipiodol containing treatments. If contrast enhanced CT images are desired, obtaining a non-contrast image may be helpful to discriminate DC Bead LUMI from contrast enhancement.

The radiopacity of DC Bead LUMI does not degrade over time, so the beads will continue to be visible at follow up.

Drug Loading and Elution

  • Approved for loading with doxorubicin and irinotecan.
  • In-vitro testing confirms that the controlled and sustained elution profiles of drug from DC Bead LUMI™are comparable to those achieved with DC Bead™
  • Elution of doxorubicin and irinotecan falls within the same window as DC Bead™1
  • Under the same conditions, both DC Bead LUMITM  and DC BeadTM achieve complete elution of doxorubicin and irinotecan 1,2 
  • DC Bead LUMITM do not reduce in diameter when loaded with drug.
