US 10,369,032 B2 · Transluminal delivery system

Abstract

A transluminal delivery system and a method of assembling. The system includes a cylindrical, inner-catheter component and a retractable sheath surrounding the component and defining a space between the component and the sheath to receive a self-expanding luminal prosthesis between the component and the sheath. The inner-catheter component may include at least one sleeve having fibers, at least one connected sleeve portion connected to the inner catheter, and at least one unconnected sleeve portion slidably engaging the inner catheter such that when the sheath retracts, the unconnected portion expands and sleeve fibers engage the prosthesis's luminal surface, wherein the engagement opposes proximal stent movement.

Dependent claims

A transluminal delivery system for deploying a stent in a patient, comprising:

a retractable sheath positioned over the stent;
and
an inner catheter positioned through a lumen of the stent, the inner catheter comprising:
a tubular portion having an abluminal surface;
and
a cylindrical braid element positioned over the abluminal surface of the tubular portion, the cylindrical braid element comprising:
an inner surface contacting the abluminal surface of the tubular portion over an entire length of the cylindrical braid element;
a proximal region bonded to the abluminal surface of the tubular portion;
and
an unbonded distal end slidably disposed on the abluminal surface of the tubular portion.
