1. A system, comprising:
- an outer tubular member defining a lumen;
an inner tubular member extending within the lumen of the outer tubular member, the inner tubular member having a sidewall defining an aperture configured to allow a guide wire to pass therethrough, the inner and outer tubular members being configured so that an implantable medical endosprosthesis can be disposed between the inner and outer tubular members;
a support member disposed in a lumen of the inner tubular member, the support member being configured such that at least a portion of the support member can be disposed adjacent the aperture, the support member and the outer tubular member being configured to retract relative to the inner tubular member, wherein the support member has a solid cross-section;
wherein a portion of the sidewall of the inner tubular member proximal to the aperture defines a plurality of cuts so as to increase the flexibility of the inner tubular member while allowing the inner tubular member to be pushable in the distal direction; and
wherein a portion of the sidewall of the inner tubular member distal to the aperture defines at least one cut in the form of a continuous spiral for increasing the flexibility of the inner tubular member.

Abstract
Medical systems and related methods are disclosed. In some embodiments, the medical systems include an inner tubular member defining an aperture and an outer tubular member at least partially surrounding the inner tubular member. The inner and outer tubular members can be arranged such that an implantable medical endoprosthesis can be disposed therebetween.

19. A system, comprising:
-
an inner tubular member having a sidewall defining an elongate slot, the inner tubular member being formed of one or more metals; an outer tubular member at least partially surrounding the inner tubular member, the outer tubular member having a sidewall at least partially defining an opening arranged such that a guide wire can be passed through the elongate slot of the inner tubular member and the opening of the outer tubular member, the inner tubular member and the outer tubular member being arranged such that an implantable medical endoprosthesis can be disposed between the inner tubular member and the outer tubular member; wherein a portion of the sidewall of the inner tubular member proximal to the elongate slot defines a plurality of cuts arranged in the form of an interrupted spiral; wherein a portion of the sidewall of the inner tubular member distal to the elongate slot defines at least one cut that is arranged in the form of a continuous spiral; and a solid support member having a solid cross-section disposed in a lumen of the inner tubular member, the support member being configured such that at least a portion of the support member can be disposed adjacent the elongate slot, and the support member being arranged to retract relative to the inner tubular member. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28)
