QuadraSphere Microspheres are indicated for embolization of hypervascularized tumors including hepatoma, and peripheral arteriovenous malformations.
Device Description
QuadraSphere Microspheres are sterile, biocompatible, hydrophilic, nonresorbable, expandable, acrylic copolymer microspheres. QuadraSphere Microspheres are packaged in a vial containing 25 mg of dry microspheres. The expansion rate is dependent on ionic concentration. When in contact with blood, non-ionic contrast media, or normal saline (NaCl 0.9%), QuadraSphere Microspheres expand to approximately 4 times their dry state diameter; equal to 64x volume. They are available in a range of sizes.
More Information

Not Found

No
The description focuses on the physical properties and performance of the microspheres for embolization, with no mention of AI or ML in the device description, intended use, or performance studies.

Yes
The device is used for embolization of hypervascularized tumors and arteriovenous malformations, which is a therapeutic intervention aimed at treating medical conditions.

No
The device is described as an embolization agent used for treating hypervascularized tumors and arteriovenous malformations, which is a therapeutic rather than a diagnostic function.

No

The device description clearly states that the device is composed of physical microspheres, which are a hardware component. The performance studies also focus on the physical properties and behavior of these microspheres.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
  • Device Description and Intended Use: The description of QuadraSphere Microspheres clearly states they are used for embolization of hypervascularized tumors and arteriovenous malformations. This is a therapeutic procedure performed within the body to block blood vessels.
  • Lack of Diagnostic Testing: There is no mention of this device being used to analyze samples from the body or provide diagnostic information. Its function is purely mechanical (blocking blood flow).

Therefore, QuadraSphere Microspheres are a therapeutic medical device, not an in vitro diagnostic device.

Device Description

QuadraSphere Microspheres are sterile, biocompatible, hydrophilic, nonresorbable, expandable, acrylic copolymer microspheres. QuadraSphere Microspheres are packaged in a vial containing 25 mg of dry microspheres. The expansion rate is dependent on ionic concentration. When in contact with blood, non-ionic contrast media, or normal saline (NaCl 0.9%), QuadraSphere Microspheres expand to approximately 4 times their dry state diameter; equal to 64x volume.
They are available in a range of sizes.

  • Spherical shape with consistent cross sectional diameter after reconstitution with aqueous-based solutions such as contrast media and 0.9% saline solution for predictable flow directed level of occlusion in the vasculature.
  • Rapidly absorb contrast media and 0.9% saline solution.
  • Conform to vessel lumen, providing more surface contact with vessel intima.
  • Expand up to four times the stated dry diameter when hydrated with non-ionic aqueous solutions, resulting in an increase in surface area contact for a more complete vessel occlusion.

The principles of operation for the QuadraSphere Microspheres are the same as the predicate device K153102. QuadraSphere Microspheres are permanent implantable devices and are designed for controlled, targeted embolization. The device is provided dry (in a vial) and must be rehydrated before use. The microspheres are injected into the target vessel with an intravascular catheter(s) to selectively occlude blood vessels. Contrast enhancement using commercially available ionic or non-ionic contrast media allows the embolization procedure to be monitored using fluoroscopy. The embolization agents are intended for single use and are provided sterile.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Safety & Performance Tests
No performance standards applicable to this device have been adopted under Section 514 of the Act. However, vascular 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.

Biocompatibility assessment was performed in accordance with ISO 10993-1 for permanent implants in contact with blood for the predicate device and are being adopted for this subject device based upon the fact that both devices are made from the same materials using the same processes with now the inclusion of an additional size offering.

In-vitro and in-vivo (animal study) design verification and validation testing demonstrates that the BioSphere Medical QuadraSphere Microspheres 20 to 40µm fulfill design and performance specifications. Performance testing of the subject device was conducted based on the requirements of design input and output requirements as below:

  • Macroscopic appearance of the powder
  • Microscopic examination of the microspheres
  • Swelling in Hexabrix of the microspheres
  • Humidity of the microspheres
  • Bacterial endotoxins
  • Catheter compatibility
  • Animal testing
    The results of the testing demonstrated that the subject BioSphere Medical QuadraSphere Microspheres 20 to 40 µm met the pre-determined acceptance criteria applicable to the size requirements and performance of the device.
