PS Medical® Flow Control Products -- Shunts
Strata® Shunt Assemblies
Strata® Shunt Assembly, Regular
The PS Medical Strata valve is an
adjustable flow control valve in which the resistance properties of
the valve can be changed non-invasively by the caregiver. It is designed
to minimize overdrainage of cerebrospinal fluid (CSF) and maintain
intraventricular pressure (IVP) within a normal physiologic range,
regardless of patient position. The normally closed Delta chamber
mechanism opens in response to positive ventricular pressure. Working
with the ball and spring valve, this mechanism minimizes overdrainage
by utilizing the principle of hydrodynamic leverage.

Delta shunt assemblies combine the Delta valve with an integral,
open-end, radiopaque peritoneal catheter. All Delta shunt assemblies
incorporate the same product features as the Delta valves. These
include injectable reservoir domes, occluders for selective flushing,
and a completely non-metallic design. The valves are fabricated
of dissimilar materials -- polypropylene and silicone elastomer
-- reducing the chance of valve sticking and deformation. The
normally closed Delta chamber mechanism minimizes overdrainage
by utilizing the principles of hydrodynamic leverage.
Delta valves are available in two styles, two sizes, and four
performance levels, meeting the needs of most patient groups.To

The PS Medical
CSF-Snap Shunt assemblies include integral snap assembly ventriculostomy
reservoir domes. When used with a snap assembly reservoir base,
a complete shunt can be assembled without the need for ligatures,
thus reducing shunt placement time.

CSF-Unitized Shunts, Contoured |
PS Medical CSF-Flow Control Shunt assemblies
and CSF-Unitized Shunt kits incorporate a variety of features to
meet specific needs. All shunt models incorporate a CSF-Flow Control
valve.
The valve configurations include injectable reservoir domes, one
or two occluders for selective flushing, and a non-metallic design.
The
reliable membrane valve design, combined with a uniform internal
flow path, ensures optimum valve performance. The valves are fabricated
of
dissimilar materials -- polypropylene and silicone elastomer --
reducing the chance of valve sticking and deformation. Catheter components
are
designed to complete the shunt for the specific patient group. All
shunt configurations are accessorized with the end user in mind.
