Title:
二重編組シャフト
Document Type and Number:
Japanese Patent JP5256211
Kind Code:
B2
Abstract:
A dual braided catheter shaft includes a flat wire forming the inner braid, thereby potentially allowing for reduced radial thickness of the shaft. In one embodiment, the shaft (100) includes an inner polymer jacket (104), an inner braid (106) formed on the inner jacket (104), an intermediate jacket (108) formed over the inner braid (106), an outer braid (110) formed on the intermediate jacket (108) and an outer jacket (112) formed on the outer braid (110). A preferred construction process involves extruding polymer material directly onto each of the inner and outer braids (106 and 110) so that little or no air gaps remain between the polymer material and the braids (106 and 110). The braiding parameters of the inner and outer braids (106 and 110) can be varied along the length of the catheter to provide varying mechanical properties.
