Abstract
Abstract A stent delivery assembly includes a catheter for carrying an intravascular stent for use in a body lumen. The catheter assembly includes a rapid exchange feature in which a proximal port is spaced a relatively short distance form the distal end of the catheter and a relatively long distance from the proximal end of the catheter. A stent is mounted on the expandable member or balloon portion of the catheter.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
82 words
An intravascular stent delivery assembly, comprising: a. a catheter having: i. a proximal end and a distal end; ii. a distal port at the distal end; iii. a proximal port spaced a relatively short distance from the distal end and a relatively long distance from the proximal end; iv. a passageway for a guide wire extending between the distal port and the proximal port; and v. an expandable member for expanding a stent; and b. a stent disposed about the expandable member.
Claim 2
Dependent Claim
82 words
An intravascular stent delivery assembly, comprising: a. a catheter having: i. a proximal end and a distal end; ii. a distal port at the distal end; iii. a proximal port spaced a relatively short distance from the distal end and a relatively long distance from the proximal end; iv. a passageway for a guide wire extending between the distal port and the proximal port; and v. an expandable member for expanding a stent; and b. a stent disposed about the expandable member.
Claim 3
Dependent Claim
15 words
The assembly of claim 1 , wherein the stent is mounted on the expandable member.
Claim 4
Dependent Claim
44 words
The assembly of claim 1 , wherein the stent is longitudinally flexible and expandable and comprises a plurality of cylindrical elements which are independently expandable in the radial direction and which are interconnected so as to be generally aligned on a common longitudinal axis.
Claim 5
Dependent Claim
17 words
The assembly of claim 3 , wherein the cylindrical elements of the stent are out of phase.
Claim 6
Dependent Claim
13 words
The assembly of claim 1 , wherein the expandable member comprises a balloon.
Claim 7
Dependent Claim
13 words
The assembly of claim 1 , wherein the catheter has an inflation passageway.
Claim 8
Dependent Claim
17 words
The assembly of claim 6 , wherein the inflation passageway is in fluid communication with the balloon.
Claim 9
Dependent Claim
17 words
The assembly of claim 1 , further comprising a sheath having a passageway for receiving the catheter.
Claim 10
Dependent Claim
33 words
The assembly of claim 8 , wherein the sheath has a first port at a distal end of the sheath and a second port spaced distally of the proximal end of the sheath.
Claim 11
Dependent Claim
32 words
The assembly of claim 9 , wherein a slit in the sheath extends distally from the second port so that the guide wire can be pulled through the slit during catheter exchanges.
Claim 12
Dependent Claim
32 words
The assembly of claim 1 , wherein a slit in the catheter extends distally from the proximal port so that the guide wire can be pulled through the slit during catheter exchanges.
Claim 13
Dependent Claim
96 words
An intravascular stent delivery assembly comprising: a. a catheter having i. a proximal end and a distal end; ii. a distal port at the distal end; iii. a proximal port spaced a relatively short distance from the distal end and a relatively long distance from the proximal end; iv. a passageway for a guide wire extending between the distal port and the proximal port; v. a long relatively stiff proximal section; vi. a short relatively flexible distal section; and vii. an expandable member for expanding a stent; and b. a stent disposed about the expandable member.
Claim 14
Dependent Claim
96 words
An intravascular stent delivery assembly comprising: a. a catheter having i. a proximal end and a distal end; ii. a distal port at the distal end; iii. a proximal port spaced a relatively short distance from the distal end and a relatively long distance from the proximal end; iv. a passageway for a guide wire extending between the distal port and the proximal port; v. a long relatively stiff proximal section; vi. a short relatively flexible distal section; and vii. an expandable member for expanding a stent; and b. a stent disposed about the expandable member.
Claim 15
Dependent Claim
15 words

Dependent Claim
17 words
The assembly of claim 14 , wherein the cylindrical elements of the stent are out of phase.
Claim 18
Dependent Claim
21 words
The assembly of claim 12 , wherein a stiffening mandrel is disposed within at least the proximal section of the catheter.
Claim 19
Dependent Claim
13 words
The assembly of claim 12 , wherein the expandable member comprises a balloon.
Claim 20
Dependent Claim
13 words
The assembly of claim 17 , wherein the catheter has an inflation passageway.
Claim 21
Dependent Claim
17 words
The assembly of claim 18 , wherein the inflation passageway is in fluid communication with the balloon.
Claim 22
Dependent Claim
17 words
The assembly of claim 12 , further comprising a sheath having a passageway for receiving the catheter.
Claim 23
Dependent Claim
33 words
The assembly of claim 20 , wherein the sheath has a first port at a distal end of the sheath and a second port spaced distally of the proximal end of the sheath.
