SLIP LAYER DELIVERY CATHETER
First Claim
1. A self-expanding stent delivery system comprising:
- an outer tube comprising at least one layer and configured with a plurality of strips comprising a low friction material and extending from a distal end of the outer tube, the strips extending continuously from the at least one layer, each of the plurality of strips comprising a proximal and distal strip portion and terminating in a distal strip end, the plurality of strips being defined by plurality of empty slotted regions disposed between adjacent strips;
an inner tube having a proximal inner tube portion and a distal inner tube portion, the distal inner tube portion connected to the distal strip ends; and
a self-expanding stent collapsibly disposed over the inner tube and concentrically oriented between the inner tube and the outer tube, the stent defined by an inner lumenal stent side and an outer ablumenal stent side,wherein the strips are folded back into the outer tube such that the proximal strip portions are disposed between the outer tube and the ablumenal stent side and the distal strip portions are disposed between at least a portion of the inner tube and the lumenal stent side.

Abstract
A slip layer delivery catheter includes a slip layer delivery catheter includes an outer tube configured with a plurality of strips extending therefrom and terminating in a plurality of distal strip end ends, the plurality of strips defined by empty slotted regions disposed between adjacent strips. An inner tube is coaxially disposed in the outer tube. The inner tube includes a proximal inner tube portion and a distal inner tube portion connected to the distal strip ends. An endoluminal medical device is collapsibly disposed over the inner tube. The plurality of strips is folded back into the outer tube, concentrically orienting the device between the outer tube and the inner tube such that at least a portion of the strips are disposed between the outer tube and the ablumenal device side.

20. A method for fabricating a medical device delivery system comprising:
-
providing an outer tube; forming a plurality of strips in a distal end of the outer tube by removing portions of the outer tube to form a plurality of empty slotted regions between adjacent strips; co-axially disposing an inner tube within the outer tube; connecting a plurality of distal strip ends of the strips to a distal portion of the inner tube; overlaying an expandable medical device over a portion of the inner tube; and translocating a distal portion of the inner tube, the device, and the plurality of strips into the outer tube, such that at least a portion of the strips are disposed between the outer tube and an external side of the device.
