Abstract
Abstract A manifold for a double lumen angioplasty balloon catheter has a first chamber connecting the balloon lumen to a first port, a second chamber connecting the guide wire lumen to a second port and a guide wire entry port, an adjustable guide wire seal and a mounting system for an alternative elastic diaphragm guide wire feeding device. An override system for the adjustable guide wire seal is also disclosed.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
99 words
An angioplasty device comprising: an angioplasty balloon catheter having a first lumen extending therethrough in fluid connection with a distally located balloon and a second lumen extending therethrough capable of receiving a guide wire; and a manifold comprising: a first chamber connecting the first lumen to a first port; a second chamber connecting the second lumen to a second port and a guide wire entry port; means for progressively and reversibly sealing the guide wire entry port about the guide wire; and means for coupling an elastic diaphragm guide wire feed through device to the means for reversibly sealing.
Claim 2
Dependent Claim
99 words
An angioplasty device comprising: an angioplasty balloon catheter having a first lumen extending therethrough in fluid connection with a distally located balloon and a second lumen extending therethrough capable of receiving a guide wire; and a manifold comprising: a first chamber connecting the first lumen to a first port; a second chamber connecting the second lumen to a second port and a guide wire entry port; means for progressively and reversibly sealing the guide wire entry port about the guide wire; and means for coupling an elastic diaphragm guide wire feed through device to the means for reversibly sealing.
Claim 3
Dependent Claim
38 words
The device of claim 1 wherein the means for reversibly sealing comprise: an object of resilient seal material and means to simultaneously force the object in sealing contact with the guide wire and the guide wire entry port.
Claim 4
Dependent Claim
29 words
The device of claim 2 wherein the object of resilient seal material is a wire engaging "O" ring and the means to simultaneously force is a hemostatic valve nut.
Claim 5
Dependent Claim
19 words
The device of claim 3 wherein the means for coupling is a Luer fitting on the hemostatic valve nut.
Claim 6
Dependent Claim
20 words
The device of claim 1 further comprising: means for locking the means for reversibly sealing in a desired sealing condition.
Claim 7
Dependent Claim
43 words
The device of claim 5 wherein the means for reversibly sealing includes an object of resilient sealing material and means for compressing the object and wherein the means for locking includes means for frictional locking between the manifold and the means for compressing.
Claim 8
Dependent Claim
28 words
The device of claim 6 further comprising: a threaded portion; and wherein the means for compressing is a hemostatic valve nut engaging the threaded portion of the manifold.
Claim 9
Dependent Claim
40 words
The device of claim 7 further comprising: a radially extending shoulder on the manifold; a radially extending shoulder on the hemostatic valve nut; and wherein the means for frictional locking includes a frictional locking object engaging both radially extending shoulders.
Claim 10
Dependent Claim
38 words
The device of claim 8 wherein the frictional locking object is a face-sealing "O" ring interposed between the radially extending shoulders of the manifold and the hemostatic valve nut which frictionally locks the manifold and hemostatic valve nut.
Claim 11
Dependent Claim
16 words
The device of claim 5 wherein the desired sealing condition is the absence of a seal.
Claim 12
Dependent Claim
18 words
The device of claim 1 further comprising: means for sealing the means for coupling to the second chamber.
Claim 13
Dependent Claim
65 words
The device of claim 11 further comprising: a radially extending shoulder on the manifold; a hemostatic valve nut; a radially extending shoulder on the hemostatic valve nut; and wherein the means for coupling include a Luer fitting on the hemostatic valve nut and the means for sealing include a face-sealing "O" ring interposed between the radially extending shoulders of the manifold and hemostatic valve nut.
Claim 14
Dependent Claim
23 words
The device of claim 12 wherein the face-sealing "O" ring prevents a seal between the guide wire and the guide wire entry port.
Claim 15
Dependent Claim
32 words
The device of claim 1 wherein the means for reversibly sealing includes a hemostatic valve nut and wherein the manifold further comprises: means to prevent inadvertent removal of the hemostatic valve nut.
Claim 16
Dependent Claim
28 words
The device of claim 14 wherein the means to prevent inadvertent removal includes a snap fit between the hemostatic valve nut and an extension of the second chamber.
Claim 17
Dependent Claim
95 words
An angioplasty device comprising: an angioplasty balloon catheter having a first lumen extending therethrough in fluid connection with a distally located balloon and a second lumen extending therethrough capable of receiving a guide wire; and a manifold comprising: a first chamber connecting the first lumen to a first port; a second chamber connecting the second lumen to a second port and a guide wire entry port; means for reversibly sealing the guide wire entry port about the guide wire; and means for preventing the inadvertent separation of the means for reversibly sealing from the manifold.
Claim 18
Dependent Claim
95 words
An angioplasty device comprising: an angioplasty balloon catheter having a first lumen extending therethrough in fluid connection with a distally located balloon and a second lumen extending therethrough capable of receiving a guide wire; and a manifold comprising: a first chamber connecting the first lumen to a first port; a second chamber connecting the second lumen to a second port and a guide wire entry port; means for reversibly sealing the guide wire entry port about the guide wire; and means for preventing the inadvertent separation of the means for reversibly sealing from the manifold.
Claim 19
Dependent Claim
29 words
The device of claim 16 wherein the means for reversibly sealing includes a wire engaging "O" ring and a hemostatic valve nut for compressing the wire engaging "O" ring.
Claim 20
Dependent Claim
25 words
The device of claim 17 wherein the means for preventing the inadvertent separation includes a snapping arrangement between the hemostatic valve nut and the manifold.
Claim 21
Dependent Claim
69 words
The device of claim 18 wherein the snapping arrangement includes a resilient extension bore carrying the hemostatic valve nut and the bore includes at least one diameter narrowing intrusion, and the hemostatic valve nut includes a diameter increasing portion such that the resilient extension bore must be deformed for the diameter increasing portion of the hemostatic valve nut to pass the diameter narrowing intrusion of the resilient extension bore.
Claim 22
Dependent Claim
19 words
The device of claim 19 wherein the diameter narrowing intrusion is one of a pair of opposed rib projections.
