  • Catheter
    Patent number: 8858530
    Abstract: A catheter includes an inner layer, a braid, an outer layer, and a distal tip. A recessed region having a first side and a second side is formed in a distal end portion of the braid, a length of the first side being longer than the sum of a wire width of a first wire and a distance between two adjacent first wires, a length of the second side being longer than the sum of a wire width of a second wire and a distance between two adjacent second wires. The distal tip is bonded to the inner layer in the recessed region. By providing the recessed region, the number of peaks formed in the distal end portion of the braid is made smaller than that in the existing case.
