Abstract: Embodiments of the disclosure describe an example guide extension catheter. The guide extension catheter may include a proximal shaft having a proximal end, a distal end, the distal end having an attachment region. The guide extension catheter may further include a distal sheath having a proximal end, a distal end and a lumen extending therebetween. The distal sheath may include an outer layer, inner layer and an intermediate reinforcing member disposed between the inner layer and the outer layer. Moreover, the distal sheath is attached to the attachment region adjacent to the reinforcing member.
