A composition, article, and method for increasing the hydrolytic stability of a polymer; wherein a composition includes: a polymer comprising functional groups having hydrolyzable bonds; a carbodiimide compound; and a weak base (or hindered amine); wherein the carbodiimide compound and weak base (or hindered amine) are used in amounts effective to decrease the rate and/or extent of hydrolytic degradation of the polymer relative to either used alone in the same amount with the polymer.

A tubing component, and methods of forming, for a particulate material delivery assembly including a particulate delivery device to deliver a mixed particulate solution to a patient. The tubing component includes a material including a material density, and a determined thickness sufficient to shield a delivery line connector of a particulate delivery device from at least 90% of a radiation dose. The delivery line connector is configured to receive the mixed particulate solution from the particulate delivery device of the particulate material delivery assembly, and the determined thickness of the tubing component is calculated based on the material density to achieve shielding of the delivery line connector by the material of at least 90% of the radiation dose. The tubing component includes an integral wall of the delivery line connector, an outer sleeve configured to be removably disposed about the delivery line connector, or combinations thereof.

The embodiments described herein relate to a self-positioning, quick-deployment low profile transvenous electrode system for sequentially pacing both the atrium and ventricle of the heart in the dual chamber mode, and methods for deploying the same.

A method of making magnetically controllable devices for interventional medical procedures comprises the steps of: Manufacturing a medical device for interventional medical procedures having magnetic materials which are without permanent magnetization; and establishing permanent magnetization within the magnetic materials subsequent to manufacturing, wherein the permanent magnetization allows the medical device to be magnetically controllable. The method may further including the step of packaging and sterilizing the medical device, wherein establishing permanent magnetization occurs after packaging and sterilization. The establishing permanent magnetization within the magnetic materials may include providing different magnetic orientations to distinct portions of the magnetic materials. The magnetic material includes one of a platinum alloy or a palladium alloy.
