1. An implantable medical endoprosthesis delivery system, comprising:
- a catheter;
a sheath at least partially surrounding the catheter, the catheter and the sheath being configured so that an implantable medical endoprosthesis can be disposed therebetween;
a plurality of slots of material attached to the sheath; and
a tip coupled to a distal end portion of the catheter, the tip having a head portion and a proximal portion, the head portion having a shaped surface including a plurality of proximally-extending projections that are in partial contact with a distal end surface of the sheath so that a plurality of longitudinal gaps are formed between the tip and the sheath such that there is fluid communication between an interior region of the sheath and an exterior region of the sheath through the longitudinal gaps; and
wherein at least a section of the proximal portion is configured to be positioned within the slots of material.

Abstract
Medical device delivery systems, and related methods and components, are disclosed. In some embodiments, an implantable medical endoprosthesis delivery system includes a catheter, a sheath at least partially surrounding the catheter, and a tip coupled to a distal end portion of the catheter. The tip can cooperate with a distal end surface of the sheath to form a gap therebetween so that there is fluid communication between an interior region of the sheath and an exterior region of the sheath.

8. An implantable medical endoprosthesis delivery system, comprising:
-
a catheter; a sheath at least partially surrounding the catheter, the catheter and the sheath being configured so that an implantable medical endoprosthesis can be disposed therebetween; a plurality of spacer members disposed along an interior wall surface of the sheath; a tip coupled to a distal end portion of the catheter, the tip including a head portion and a proximal portion, the head portion including a surface cooperating with a distal end surface of the sheath to form a plurality of longitudinal gaps therebetween so that there is fluid communication between an interior region of the sheath and an exterior region of the sheath, wherein the surface of the tip comprises a plurality of proximally-extending projections that contact the distal end surface of the sheath at a plurality of circumferentially spaced regions; and wherein the proximal portion of the tip is configured to be positioned within the spacer members. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
