Patent ID: 11266814

Abstract:
A support catheter is used together with a guiding catheter in which a treatment catheter is inserted, the guiding catheter guiding the treatment catheter in a blood vessel, the support catheter being inserted in the guiding catheter from a proximal-side opening of the guiding catheter and having such a length that the support catheter protrudes from a distal-side opening of the guiding catheter, the support catheter guiding a distal end portion of the treatment catheter to a treatment site. The support catheter includes: a distal shaft forming a distal-side portion of the support catheter, the distal shaft having a tubular shape such that the treatment catheter is insertable in the distal shaft; and a proximal shaft forming a proximal-side portion of the support catheter. The proximal shaft is joined to a proximal-side portion of the distal shaft by a modified polyolefin-based adhesive.
