DAYVILLE, CT USA - (February 8, 2017) - Putnam Plastics Corporation, a leader in advanced extrusions for minimally invasive medical devices, has expanded their capabilities to include advanced laser machining and state-of-the-art short pulse and ultrashort pulse laser technologies. In addition, an in-house tool shop allows Putnam to design custom tooling and fixtures to handle a variety of materials and tubing in need of laser machining.
DAYVILLE, CT USA - (February 8, 2016) - Putnam Plastics Corporation, a leader in advanced extrusions and components for minimally invasive medical devices, has developed an advanced tri-layer tubing technology that significantly improves tensile and burst strength, while reducing elongation. Super-Tri™ tubing is made with a proprietary extrusion process and aids in the prevention of wire lock-up in catheters where guidewires are used.
DAYVILLE, CT, USA - (January 11, 2016) – Today, U.S. Senator Chris Murphy (D-Conn.) announced that Putnam Plastics of Dayville is this week’s “Murphy’s Monday Manufacturer.” Founded in 1984, Putnam Plastics is a family-owned developer and manufacturer of tubing, catheters, and other assemblies for the medical device industry.
DAYVILLE, CT, USA – (October 3, 2013) – Putnam Plastics Corporation, a leader in advanced extrusion for minimally invasive medical devices, reports increased interest in integrated catheter components made by medical device companies. These components leverage continuous manufacturing to combine sub-component processes, eliminate assembly steps and reduce manual labor, thus allowing device companies to reduce overall costs.
DAYVILLE, CT USA - (June 18, 2012) – Putnam Plastics Corporation, a leader in advanced extrusion for minimally invasive medical devices, has completed construction of a state of the art manufacturing and office space in Dayville, CT. The 92,000 square feet (8.4 square meters) facility will allow for expansion of extrusion technology development and manufacturing operations.
DAYVILLE, CT USA - (December 18, 2012) – Putnam Plastics Corporation, a leader in advanced extrusion for minimally invasive medical devices, introduces Taper-Tie™ variable flexibility tubing for catheter shafts that require maximum flexibility on one end for forward navigation and rigidity on the other end for directional control by physicians. Taper-Tie is a proprietary continuous extrusion technology designed to replace traditional manual assembly of segmented shafts and eliminate associated labor costs.
DAYVILLE, CT USA - (October 30, 2012) – Putnam Plastics Corporation, a leader in advanced extrusion for minimally invasive medical devices, has increased its range of custom PEEK extrusions for medical devices to include large diameter, thin wall tubing for endoscopy and laparoscopy procedures. This new offering extends Putnam’s thin wall, PEEK tubing range from microcatheter sizes up to 1 inch (25.4 mm) diameter.
DAYVILLE, CT USA - (September 11, 2012) – Putnam Plastics Corporation, a leader in advanced extrusion for minimally invasive medical devices, has added variable pitch braid and coil reinforcement to its portfolio of variable flexibility medical catheter shaft technologies. These continuous manufacturing technologies are designed to reduce cost and improve product performance of complex shafts traditionally assembled manually. Variable braiding or coiling can also be used in conjunction with geometric tapering or sequential polymer extrusion of distinct materials to enhance pushability and torque of catheters while maintaining flexibility to navigate vascular pathways deeper in the body.
Innovative processing technologies can help designers create products that perform better and cost less.
Medical tubing used in minimally invasive devices has become increasingly sophisticated. Today’s cutting-edge devices are reaching more remote regions of the human anatomy and are used to perform greater diagnostic and interventional procedures, requiring different performance properties on the exterior and interior of the catheter shaft and along the length.
The performance characteristics necessary for catheters to reach smaller distal areas within the body include pushability, torque transmission, and flexibility. Catheters are inserted into a vascular passage from a peripheral location, such as the femoral artery. The physician advances the catheter by pushing it from the proximal end and provides direction with rotational inputs that are transmitted by way of torque from the proximal end to the advancing distal tip. At the same time, the catheter must remain flexible to navigate the complex turns and branches inherent in the vascular system...
Today’s minimally invasive surgical techniques involve incisions that are small enough for a surgeon to insert a catheter into a blood vessel. These small incisions are a conduit through which instruments and devices can be inserted to treat diseased blood vessels, clean out blocked vessels, or deliver clot-dissolving medications directly at the problem area.
Vascular catheters used in minimally invasive surgery face a number of design challenges. While they must be fairly stiff at their proximal end to allow the pushing and maneuvering of the catheter as it progresses through the body, they must also be sufficiently flexible at the distal end to allow passage of the catheter tip through smaller blood vessels without causing significant trauma to the vessels themselves or to the surrounding tissue. This combination of flexibility, high tensile strength, and compression resistance is what makes designing a vascular catheter challenging.
