The QUANTUM™ 2 system
QUANTUM COBLATION™ technology takes
arthroscopic surgery to an elevated level by giving
you the power and control you require to handle
whatever you find, in every joint you treat.
Multi-electrode COBLATION devices
AMBIENT™ COBLATION Wand Collection
AMBIENT COBLATION devices are the first and only
RF wands that provide real-time visual and audible
feedback of the temperature of the irrigating fluid in the
joint space. Available in SUPER MULTIVAC™ 50, SUPER
TURBOVAC™ 90, COVAC™ 50 and 70 designs.
SUPER TURBOVAC™ COBLATION Wand
The SUPER TURBOVAC 90 Wand has powerful
suction that draws free-floating, wispy tissue to the
active electrode screen to minimize clogging. It is an
instrument of choice for tissue removal in subacromial
decompression and ACL reconstruction.
STARVAC™ COBLATION Wand
The STARVAC 90 Wand touts an innovative single
aperture, star screen design which combines
aggressive ablation speed with powerful suction.
SUPER MULTIVAC™ COBLATION Wand
The SUPER MULTIVAC 50 Wand is uniquely designed
to facilitate access to hard-to-reach parts of the
knee with its 50˚ angle. It contours tissue edges to
minimize the rough, jagged appearance that may
result from the use of mechanical instruments.
COVAC™ COBLATION Wand
COVAC 50 and 70 Wands feature a wire electrode
configuration, 50˚ and 70˚ shaft angles and beveled
tips for versatility in the knee.
ELIMINATOR™ COBLATION Wand
The ELIMINATOR 90 Wand is a right angle, nonsuction Wand that provides rapid tissue removal for
general arthroscopic soft tissue ablation. The 3.5mm
90˚ Wand is designed for your everyday arthroscopic
MENIVAC™ COBLATION Wand
MENIVAC 45 Wands features more than 20 active
electrodes for aggressive resection of meniscal
tissue. The electrode transects the suction lumen,
removing bubbles for added visibility, particularly in
the posterior meniscus.
TRISTAR™ COBLATION Wand
The TRISTAR 50 Wand maintains an enclosed
ablation field surrounding the whole Wand tip. The
low profile allows access to hard to reach sections
of the meniscus and around delicate articular
DOME™ COBLATION Wands
DOME Wands have dome-shaped electrode
configurations, providing increased contact with
curbed tissue structures. This design helps maintain
tissue contact when access angles vary. DOME
Wands are available in two shaft angles (30˚ and
60˚) for flexibility.
BEVEL™ COBLATION Wands
BEVEL Wands have versatile cutting angles in slimline designs for ease of insertion. The BEVEL Wands
are available with three shaft angles (30˚, 45˚ and
60˚) for a wide variety of surgical applications.

Establish, maintain, and maximize a plasma layer
• Establishes a plasma layer quickly and efficiently
• Maintains a stable and aggressive plasma layer
• Maximizes the size of the plasma layer
OBLATION devices establish a plasma layer of
reactive particles that disrupt organic molecular
bonds in target tissue, and rapidly disintegrate
the tissue, resulting in volumetric removal of
tissue with minimal damage to collateral tissue.1
3 T he COBLATION plasma layer is created by
current flowing between closely-spaced, bipolar
electrodes. This current forms a high density
energy field that rapidly vaporizes a thin layer
of a conductive liquid (saline or Ringer’s lactate
solution) at the surface of the electrode into
a glow discharge plasma of very reactive and
energized ions and electrons.
Multi-electrode technology provides the three
key requirements for the clinically-effective
COBLATION plasma layer:
a. Establishes a plasma layer quickly and efficiently
b. Maintains a stable and aggressive plasma layer
c. Maximizes the size of the plasma layer
establish the ablative plasma layer quickly,
high current density is required. The bipolar
configuration of the COBLATION device, where
the electric field is concentrated between the
active electrode at the Wand tip and the return
electrode at the base of the tip, provides the
energy density to form the reactive ion ablation
5 The current density necessary to establish a
plasma layer is formed first at an electrode edge
where there is a current field enhancement.
With equal surface areas, multiple electrodes
offer more edge length than a single electrode,
thus forming a plasma layer more quickly. This
minimizes the time between initial application of
current and plasma layer formation.
1 COBLATION™ technology, controlled ablation,
offers an alternative from other radiofrequency
electrosurgical techniques that cut or remove
tissue by delivering large amounts of energy or
heat in order to desiccate and pyrolyze tissue to be
In addition, each electrode has an independent
power channel. Current supplied for each
electrode is reduced as that electrode forms
a plasma layer and resistance increases. This
minimizes total current and subsequent power or
heat dissipated to collateral tissue.
The plasma layer is in constant flux, forming and
reforming 100,000 times per second at each
electrode. This layer requires continual renewal as
tissue is ablated and fluid flow carries away the
vapor layer. With properly positioned electrode
arrays, the plasma layer can be renewed and
stabilized while avoiding the thermal inertia of
single electrodes with larger mass.
6 F or maximum ablation, the volume of the plasma
layer should be as large as possible. Since
the distance of the plasma layer around each
electrode typically ranges from 50 to 100µm,
multiple electrodes can be spaced to create a
large, almost uninterrupted, plasma layer without
a proportional increase in power.2
Careful selection of electrode number, size, and spacing creates an ablation layer best suited for your
needs. The QUANTUM™ 2 system is designed to power a selection of over 50 unique COBLATION
devices, each carefully designed for today’s arthroscopic procedures.
