TRIMMABLE CATHETER INCLUDING DISTAL PORTION STABILITY FEATURES
摘要
A catheter tube for insertion into a body of a patient is disclosed. The catheter tube includes a distal portion that remains stable during fluid infusion into the patient, thus reducing or eliminating whipping of the catheter distal tip, even during power injection. In one embodiment, the catheter tube defines at least one lumen and is formed from a tube material that defines a proximal portion and a distal portion of the catheter tube. The catheter tube is configured such that the arithmetic product of an elastic modulus and an area moment of inertia for at least a portion of the distal portion of the catheter tube defined by the catheter tube material is greater relative the arithmetic product of an elastic modulus and an area moment of inertia for at least a portion of the proximal portion of the catheter tube.
