Raleigh, North Carolina - Polyzen, which provides solutions for medical device OEMs, says it can now provide product designers with an alternative to latex materials for the construction of low-pressure balloons.
A series of polyurethane films from Polyzen can be thermoformed, then welded together to form a medical balloon that achieves previously unattainable high neck-to-body ratio, the company claims. Polyzen said in a 1 Feb news release that these polyurethane films represent a materials source that offers quick turn-around times by facilitating the design, prototyping, manufacturing and assembly capabilities of the balloons.
The balloons, which can be used for gastrointestinal and vascular devices, as well as in catheters used for drug delivery, are fully three-dimensional, exhibit a nearly invisible seam, and can be produced in thicknesses ranging from 1 to 10 mils (0.0254 to 0.254 millimetres).
Previously, the configuration of non-latex, low-pressure balloons were undesirable due to limitations of the two-dimensional form, and the low-pressure between 1-2 psi was too low for certain medical applications, according to Polyzen. The company can offer 3D designs with pressures up to 5 psi. The special welding process allows Polyzen the ability to produce polyurethane balloons to into full three-dimensional shapes.
