Published: — with international search report (Art. 21(3)) (54) Title: INTRAVASCULAR DEVICE DELIVERY SHEATH (57) : An intravascular delivery system includes a delivery sheath ca- pable of transmitting a predetermined tension or compression force in a longi- 224 7-212 tudinal direction while maintaining flexibility to navigate tortuous anatomy. A method of delivering a medical device includes inserting an intravascular device 222 delivery system including a delivery sheath having a continuous spine into a bodily lumen. A distal longitudinal force is applied to the delivery sheath. The distal force is transmitted through the continuous spine and across one or more slit cuts of the delivery sheath. A proximal longitudinal force is applied to the delivery sheath. The proximal longitudinal force is transmitted through the con- tinuous spine of the delivery sheath. FIG. 6
