CATHETER, MEDICAL DEVICES AND POLYMER MATERIAL USED FOR MEDICAL DEVICES

摘要

PROBLEM TO BE SOLVED: To provide materials having characteristics to make the materials usable according to applications having a selective range of flexibility and a catheter and medical devices formed by such materials. SOLUTION: This catheter has a catheter shaft 12 having a proximal and distal end 20, defining an inflation lumen 14 and a polymer balloon 18 which is affixed to the catheter shaft 12 near the distal end 20 and the interior of which the communicates with the infarction lumen 14. At least a portion of the catheter shaft 12 is made of a polymer blend of polyamide and maleated polyethylene.
