Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
80 words
An adjustable sideholes catheter, comprising an inlying catheter having a distal end and a proximal end wherein said distal end has multiple sideholes and wherein said distal end has at least two discrete radiopaque marks; an outlying catheter having a distal end and a proximal end wherein said proximal end has an irrigation port; wherein said outlying catheter has a slightly greater diameter than said inlying catheter, enabling said outlying and inlying catheters to be moved slidably back and forth.
Claim 2
Dependent Claim
80 words
An adjustable sideholes catheter, comprising an inlying catheter having a distal end and a proximal end wherein said distal end has multiple sideholes and wherein said distal end has at least two discrete radiopaque marks; an outlying catheter having a distal end and a proximal end wherein said proximal end has an irrigation port; wherein said outlying catheter has a slightly greater diameter than said inlying catheter, enabling said outlying and inlying catheters to be moved slidably back and forth.
Claim 3
Dependent Claim
16 words
The adjustable sideholes catheter of claim 1, wherein said catheter is made of lower frictional polyethylene.
Claim 4
Dependent Claim
22 words
The adjustable sideholes catheter of claim 1, wherein said inlying catheter has multiple sideholes on its distal part between two radiopaque markers.
Claim 5
Dependent Claim
35 words
The adjustable sideholes catheter of claim 1, wherein said outlying catheter is long enough to reach the nearest sidehole of the inlying catheter when the proximal parts of the inlying and outlying catheters are attached.
Claim 6
Dependent Claim
28 words
The adjustable sideholes catheter of claim 1, wherein said inlying catheter has an internal diameter selected from the group consisting of 3 F, 4 F and 5 F.
Claim 7
Dependent Claim
23 words
The adjustable sideholes catheter of claim 1, wherein said inlying catheter has a length of from about 65 cm to about 125 cm.
Claim 8
Dependent Claim
25 words
The adjustable sideholes catheter of claim 1, wherein said inlying catheter with sideholes has a length of from about 10 cm to about 20 cm.
Claim 9
Dependent Claim
16 words
The adjustable sideholes catheter of claim 1, wherein said sideholes are spaced approximately 0.5 cm apart.
Claim 10
Dependent Claim
16 words
The adjustable sideholes catheter of claim 1, wherein said intervals of each sidehole are spirally arranged.
Claim 11
Dependent Claim
16 words
The adjustable sideholes catheter of claim 1, wherein said sideholes are approximately 0.009 inches in diameter.
Claim 12
Dependent Claim
28 words
The adjustable sideholes catheter of claim 1, wherein said outlying catheter has an internal diameter selected from the group consisting of 5 F, 6 F and 7 F.
Claim 13
Dependent Claim
26 words
The adjustable sideholes catheter of claim 1, wherein said outlying catheter has a length approximately 10 cm to about 20 cm shorter than corresponding inlying catheter.
Claim 14
Dependent Claim
20 words
The adjustable sideholes catheter of claim 1, wherein said irrigation port of said outlying catheter is a three way stopcock.
Claim 15
Dependent Claim
22 words
The adjustable sideholes catheter of claim 1, wherein a 0.032-inch to 0.035-inch guide wire is freely advanceable beyond the inlying catheter tip.
Claim 16
Dependent Claim
21 words
The adjustable sideholes catheter of claim 1, wherein a catheter introduction sheath introduces the adjustable sideholes catheter into a blood vessel.
Claim 17
Dependent Claim
33 words
The adjustable sideholes catheter of claim 1, wherein said catheter is used to simplify catheterization of angiography by adjusting the outlying catheter to control the number of functional sideholes on the inlying catheter.
Claim 18
Dependent Claim
20 words
The adjustable sideholes catheter of claim 1, wherein said catheter is used to remove blood clots through said outlying catheter.
Claim 19
Dependent Claim
