Estimating the term…
An intravascular catheter such as a guiding catheter of composite construction having a nontraumatic distal tip comprising a proximal elastomeric tubular element and a distal elastomeric tubular element formed of softer material that the proximal section. The proximal tubular section of the distal tip preferably has a radiopaque material incorporated therein to enable the distal tip to be fluoroscopically observable when in place within a patient. The shaft of the catheter, which exhibits excellent torquability and pushability, is formed with a very thin wall. The catheter shaft includes an inner tubular member of braided polymeric fibrous strands impregnated with a thermoset polyurethane and having an outer jacket or coating of thermoplastic polyurethane secured to the braided tubular member. In some embodiments it is preferred to include a lubricous liner within the braided tubular member.
An intravascular catheter comprising:
A torquable guiding catheter having an elongated tubular shaft with an inner lumen extending therein and having a preformed distal portion with a soft, relatively short and straight distal tip which facilitates a nontraumatic advancement through a patient's vasculature, comprising:
