An inner catheter for deployment of a medical device can include a pusher band having a passage that includes a first portion extending from a first end to a position and a second portion extending from a second end to the position. A cross-sectional area of the second portion can be less than a cross-sectional area of the first portion to form a step. A second end of the first tubular member having first and second ends can be within the first portion of the pusher band, abut the step and be unable to pass through the second portion. A portion of a second tubular member having first and second ends can be within the pusher band, and the second end of the second tubular member can extend away from the second end of the pusher band and be configured to extend through a medical device.

Inner catheter with a pusher band

A delivery system is provided for self-expanding medical devices, such as stents. The delivery system has a restraining sheath that maintains the stent in a compressed state prior to deployment. The restraining sheath terminates distally from the deployment handle, and a wire connects the restraining sheath to the deployment handle. The restraining sheath is withdrawn from the stent to deploy the stent by pulling the wires proximally at the deployment handle.

Delivery system for a self-expanding medical device

An introducer sheath includes an elongated tubular member having a passageway extending generally longitudinally therethrough. The passageway is defined by an inner surface of the tubular member and configured to receive a medical device movably disposed therein. The introducer sheath further includes a reinforcing member engaged with the inner surface of the tubular member and extending into the passageway such that a non-uniform surface for receiving the medical device is defined thereby. The reinforcing member also has a surface therein suitable for facilitating movement of the medical device through the passageway.

Introducer sheath having a non-uniform inner surface

A delivery system for a self-expanding medical device is provided. The delivery system includes an outer sheath that radially restrains the medical device. First and second inner catheters are disposed within the outer sheath. The first inner catheter is a composite structure with a closed coil wire covered by a polymer outer layer. The second inner catheter is disposed within the closed coil wire but is not attached to the closed coil wire.

Inner catheter arrangement for a self-expanding medical device delivery system

An introducer sheath has a proximal segment and distal segment. The proximal segment includes an inner portion, and a polymeric outer covering portion. The inner portion is formed from a plurality of elongated strands circularly positioned around a longitudinal axis. Each strand includes axial twist portions arranged to define a generally helical strand profile, wherein the twist portions are complementary with twist portions of adjacent strands to define the tubular segment. A tubular distal segment is dimensioned to receive an elongated stent for deployment. The length of the proximal segment is greater than the length of the distal segment, and the outer diameter of the distal segment may exceed that of the proximal segment. A stability sheath may be received over the proximal segment to enhance the stability of the sheath.
