LC Bead LUMI™

Device-Type

Embolic Particles/Beads

Manufacturer

Boston Scientific


LC Bead LUMI is the world’s first microsphere offering inherent, long-term radiopacity combined with the trusted performance of LC Bead.

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

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


Contrast Agents

LC 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 LC 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. LC Bead LUMI is visible on X-ray as the beads accumulate in the vessel and the contrast clears.

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 LC Bead LUMI.
  • Optiray 350, Oxilan 350, and Isovue 370 have not been tested for the 300-500μmm size range.
  • 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 LC Bead LUMI.


Radiopacity and Visualization


LC Bead LUMI is radiopaque from the proven core chemistry used in LC 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 LC Bead LUMI will be visible on imaging at long-term follow-up.


LC 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.


LC Bead LUMI is easily visualized with CT. Early experience images from various different tumor types, show discrete embolized vessels where LC Bead LUMI is present with no significant streak artifacts 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 LC Bead LUMI from contrast enhancement.


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

Features and Benefits

LC Bead LUMI™ — See More. Treat Smarter.


VISION

With LC Bead LUMI™, you are empowered to see the bead during and after treatment. During LUMI embolization — see precisely where LC Bead LUMI™ need to be delivered.

LC Bead LUMI™ offers you a new level of control with real-time feedback both during and after embolization.

 

PRECISION

LC Bead LUMI™ is designed to offer a more precise and controlled procedure than current techniques.

LC Bead LUMI™ enables real-time adjustment during the whole procedure.

 

ASSURANCE

LC Bead LUMI™ offers the precision and control you need to:

  • Modify the procedure in real time
  • Evaluate the completeness of treatment
  • Inform decisions of future patient management


Presentation

  • LC 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 LC Bead LUMI™ and sterile physiological saline is approximately 8ml. 
  • Each package contains a sterile 20mm ViaLok™ Vented Vial Access Device (Yukon Medical LLC, 4021 Stirrup Creek, Durham, NC USA) for removal of LC Bead LUMI™ from the vial. 
  • Each vial of LC Bead LUMI™ is intended for single patient use only. Do not re-sterilize. Discard any unused material.


Safety informations

CONTRAINDICATIONS

  • Patients intolerant to occlusion procedures
  • Vascular anatomy or blood flow that precludes catheter placement or injection of embolics
  • Presence or likely onset of vasospasm
  • Presence or likely onset of hemorrhage
  • Presence of severe atheromatous disease
  • Lesion/tumor-feeding vessel with diameter smaller than any distal vessel(s) branching from it
  • Presence of patent extra-to-intracranial anastomoses or shunts
  • Presence of end arteries leading directly to cranial nerves
  • Presence of arteries supplying the lesion/tumor not large enough to accept LC Bead LUMI™
  • Vascular resistance peripheral to the feeding arteries precluding passage of LC Bead LUMI™ into the lesion/tumor
  • Presence of collateral vessel pathways potentially endangering normal territories during the embolization procedure that cannot be coiled or blocked
  • Presence of high-flow arteriovenous shunt with a diameter greater than the selected bead size that cannot be coiled or blocked
  • Do not use LC Bead LUMI™ in the following applications:
  • Embolization of arteriovenous (AV) shunts (i.e. where the blood does not pass through the arterial/capillary/venous transition but directly from artery to vein)
  • Any vasculature where LC Bead LUMI™ could pass directly into the internal carotid artery or other non-target territories
  • Any neurovascular indication14. Do not use in the pulmonary arterial vasculature

CAUTIONS

  • If there are any symptoms of unwanted embolization during injection, consider stopping the procedure to evaluate the possibility of shunting. Such symptoms may include changes in patient’s vital signs, such as hypoxia or central nervous system changes.
  • In case of hypersensitivity to contrast agents it is recommended not to use LC Bead LUMI™
  • Non-target embolization may occur in the presence of arteriovenous anastomosis, branch vessels which lead away from the targeted embolization area, or emergent vessels not evident prior to embolization. The patient may experience severe complications as a result of non target embolization. Special care should be taken to avoid ischemia of non-tolerant, non-targeted tissue
  • Patients with prior biliary surgery, bile duct dilation or vessels close to bile ducts may be at increased risk from infection (e.g. biloma/ liver abscess)
  • Consideration should be given to Tc99m-MAA scanning if there is suspicion of AV shunting, especially when using the smaller bead sizes
  • Risks of radiation from angiography and fluoroscopy used to visualise the blood vessels during embolization which may include a radiation burn and risks to future fertility.

Potential adverse events

  • Undesirable reflux or passage of LC Bead LUMI™ into normal arteries adjacent to the targeted lesion or through the lesion into other arteries or arterial beds, such as the pulmonary, internal carotid or coronary circulations
  • Non-target embolization for example:
  • Pulmonary embolization
  • Pancreatitis
  • Deep vein thrombosis, or clotting of a deep vein in patient’s leg(s)
  • Thrombosis of the artery at the incision site for arterial access
  • Ischemia at an undesirable location
  • Capillary bed saturation and tissue damage
  • Ischemic stroke or ischemic infarction
  • Vessel or lesion/tumor rupture and hemorrhage
  • Neurological deficits including cranial nerve palsies
  • Vasospasm
  • Recanalization
  • Foreign body reactions necessitating medical intervention
  • Infection necessitating medical intervention
  • Clot formation at the tip of the catheter and subsequent dislodgement causing arterial thromboembolic sequelae
  • Post embolization syndrome which may include nausea, fever, pain and increases in laboratory parameters such as elevated liver enzymes
  • Allergic reactions to contrast agents or LC Bead LUMI™ in patients who are allergic or with known sensitivity to iodine / iodine containing substances
  • Embolization of the wrong artery or migration of the beads to other parts of the body, which may necessitate further treatment
  • Haematoma, or bruising or arterial aneurysm, at the arterial access incision site
  • Liver abscess
  • Death
