Abstract
Abstract A device and method for enabling substantially uniform and tight crimping of an intravascular stent onto a balloon catheter assembly. The device has a base portion having an intermediate portion and pivoting arm portions attached thereto. A loop portion is attached at its end portions to the pivoting handle portions. The loop portion has a compressible and generally cylindrical opening which is substantially uniformly compressible radially inwardly upon pivoting the arm portions downwardly from the intermediate portion. This substantially uniformly and tightly crimps the stent onto the catheter portion which is inserted therein.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
132 words
A stent crimping tool in combination with a stent, comprising: a base having a central intermediate portion and two outstretched pivotable arms that pivot toward each other; a flexible loop portion disposed on the intermediate portion, the loop portion including first and second edges with at least one row of apertures and a corresponding plurality of fingers extending from the first edge of the loop portion, wherein the loop portion is rolled into a loop and the fingers pass through the apertures; and wherein the fingers are anchored to one arm and the second edge is anchored to another arm; and wherein the stent is mounted on a catheter and disposed inside the loop portion and the two arms are pivoted toward each other to collapse the loop thereby crimping the stent.
Claim 2
Dependent Claim
132 words
A stent crimping tool in combination with a stent, comprising: a base having a central intermediate portion and two outstretched pivotable arms that pivot toward each other; a flexible loop portion disposed on the intermediate portion, the loop portion including first and second edges with at least one row of apertures and a corresponding plurality of fingers extending from the first edge of the loop portion, wherein the loop portion is rolled into a loop and the fingers pass through the apertures; and wherein the fingers are anchored to one arm and the second edge is anchored to another arm; and wherein the stent is mounted on a catheter and disposed inside the loop portion and the two arms are pivoted toward each other to collapse the loop thereby crimping the stent.

Claim 7
Dependent Claim
148 words
A stent crimping tool in combination with a stent, comprising: a base having a top face and a bottom face including an intermediate portion and two arms pivotably joined to the intermediate portion at the bottom face; a flexible sheet loop portion disposed on the top face at the intermediate portion, the loop portion having first and second edges with at least one row of apertures and a corresponding plurality of fingers extending from the first edge of the loop portion, wherein the loop portion is rolled into a loop and the fingers pass through the apertures; and wherein the fingers are affixed to one arm and the second edge is affixed to another arm; and wherein the stent is mounted on a catheter and disposed inside the loop portion and the two arms are pivoted toward the bottom face to collapse the loop thereby crimping the stent.
Claim 8
Dependent Claim
148 words
A stent crimping tool in combination with a stent, comprising: a base having a top face and a bottom face including an intermediate portion and two arms pivotably joined to the intermediate portion at the bottom face; a flexible sheet loop portion disposed on the top face at the intermediate portion, the loop portion having first and second edges with at least one row of apertures and a corresponding plurality of fingers extending from the first edge of the loop portion, wherein the loop portion is rolled into a loop and the fingers pass through the apertures; and wherein the fingers are affixed to one arm and the second edge is affixed to another arm; and wherein the stent is mounted on a catheter and disposed inside the loop portion and the two arms are pivoted toward the bottom face to collapse the loop thereby crimping the stent.
Claim 9
Dependent Claim
24 words
The stent crimping tool of claim 6, wherein flexible sheet loop portion includes a material selected from the group consisting of capton or mylar.
Claim 10
Dependent Claim
14 words
The stent crimping tool of claim 6, wherein the base includes a polymeric material.
Claim 11
Dependent Claim
16 words
The stent crimping tool of claim 6, wherein the base and arms include a block shape.
Claim 12
Independent Claim
160 words
A method of crimping a stent to a catheter comprising the steps of: providing a base having a top face and a bottom face including an intermediate portion; providing two arms pivotably joined to the intermediate portion at the bottom face; providing a flexible sheet loop portion, the loop portion having first and second edges with at least one row of apertures and a corresponding plurality of fingers extending from the first edge of the loop portion; disposing the flexible sheet portion on the top face at the intermediate portion; rolling the loop portion into a loop; passing at least one of the fingers through at least one of the apertures; anchoring at least one of the fingers to one arm; anchoring the second edge to another arm; mounting the stent on the catheter; disposing the stent and catheter inside the loop portion; and pivoting the two arms toward the bottom face to collapse the loop thereby crimping the stent.
Claim 13
Independent Claim
160 words
A method of crimping a stent to a catheter comprising the steps of: providing a base having a top face and a bottom face including an intermediate portion; providing two arms pivotably joined to the intermediate portion at the bottom face; providing a flexible sheet loop portion, the loop portion having first and second edges with at least one row of apertures and a corresponding plurality of fingers extending from the first edge of the loop portion; disposing the flexible sheet portion on the top face at the intermediate portion; rolling the loop portion into a loop; passing at least one of the fingers through at least one of the apertures; anchoring at least one of the fingers to one arm; anchoring the second edge to another arm; mounting the stent on the catheter; disposing the stent and catheter inside the loop portion; and pivoting the two arms toward the bottom face to collapse the loop thereby crimping the stent.
