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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The transluminal delivery system according to claim 1, wherein the proximal region of the cylindrical braid element is adjacent a proximal end of the stent prior to deployment of the stent. ### Claim 3 (depends on 2) The transluminal delivery system according to claim 2, further comprising a collar connected to the retractable sheath and a pulling member, wherein a proximal end of the proximal region of the cylindrical braid element is adjacent the collar prior to deployment of the stent. ### Claim 4 (depends on 2) The transluminal delivery system according to claim 2, wherein a distal end of the cylindrical braid element is within the lumen of the stent prior to deployment of the stent. ### Claim 5 (depends on 1) The transluminal delivery system according to claim 1, wherein the cylindrical braid element is a first braid element, and wherein the inner catheter further comprises a second braid element having a second proximal region bonded to the abluminal surface of the tubular portion, and a second unbonded distal end slidably disposed on the abluminal surface of the tubular portion. ### Claim 6 (depends on 1) The transluminal delivery system according to claim 1, wherein the cylindrical braid element comprises a plurality of filaments formed from at least two different materials. ### Claim 7 (depends on 6) The transluminal delivery system according to claim 6, wherein one of the at least two different materials is polyurethane. ### Claim 8 (depends on 1) The transluminal delivery system according to claim 1, wherein the cylindrical braid element is enclosed in a thin polymer matrix. ### Claim 9 (depends on 1) The transluminal delivery system according to claim 1, wherein the cylindrical braid element comprises a plurality of filaments having a non-circular cross-section. ### Claim 10 (depends on 1) The transluminal delivery system according to claim 1, wherein the abluminal surface of the tubular portion of the inner catheter is roughened. ### Claim 11 (depends on 1) The transluminal delivery system according to claim 1, wherein the cylindrical braid element distal of the proximal region is 5 mm. ### Claim 12 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 two or more cylindrical braid elements positioned over the abluminal surface of the tubular portion, each of the two or more cylindrical braid elements comprising: an inner surface contacting the abluminal surface of the tubular portion over an entire length thereof; 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. ### Claim 13 (depends on 12) The transluminal delivery system according to claim 12, wherein the two or more cylindrical braid elements comprise a first cylindrical braid element, a second cylindrical braid element, and a third cylindrical braid element. ### Claim 14 (depends on 13) The transluminal delivery system according to claim 13, wherein the proximal region of the first cylindrical braid element is adjacent a proximal end of the stent prior to deployment of the stent. ### Claim 15 (depends on 14) The transluminal delivery system according to claim 14, further comprising a collar connected to the retractable sheath and a pulling member, wherein a proximal end of the proximal region of the first cylindrical braid element is adjacent the collar prior to deployment of the stent. ### Claim 16 (depends on 13) The transluminal delivery system according to claim 13, wherein a distal end of each of the first, second, and third cylindrical braid elements is within the lumen of the stent prior to deployment of the stent. ### Claim 17 (depends on 12) The transluminal delivery system according to claim 12, wherein at least one of the two or more cylindrical braid elements comprises a plurality of filaments formed from at least two different materials. ### Claim 18 (depends on 17) The transluminal delivery system according to claim 17, wherein one of the at least two different materials is polyurethane. ### Claim 19 (depends on 12) The transluminal delivery system according to claim 12, wherein at least one of the two or more cylindrical braid elements is enclosed in a thin polymer matrix. ### Claim 20 (depends on 12) The transluminal delivery system according to claim 12, wherein the abluminal surface of the tubular portion of the inner catheter is roughened.
