Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
78 words
A hemostatic valve comprising an exit port adapted for connection to a guiding catheter or the like, an instrumentation port in fluid communication with the exit port, a first sealable access port adapted to receive a first elongate element which passes through the guiding catheter, and a second access port sealable independently of the first access port for receiving a second elongate element which passes through the guiding catheter and can be manipulated independently of the first element.
Claim 2
Dependent Claim
78 words
A hemostatic valve comprising an exit port adapted for connection to a guiding catheter or the like, an instrumentation port in fluid communication with the exit port, a first sealable access port adapted to receive a first elongate element which passes through the guiding catheter, and a second access port sealable independently of the first access port for receiving a second elongate element which passes through the guiding catheter and can be manipulated independently of the first element.
Claim 3
Dependent Claim

Claim 4
Dependent Claim
49 words
A hemostatic valve as claimed in claim 1 or claim 2 including at least one addditional access port sealable independently of the other access ports for receiving at least one additional elongate element which passes through the guiding catheter and can be moved independently of the other elongate elements.
Claim 5
Independent Claim
76 words
An apparatus for use in angioplasty, comprising: a valve having an exit port, an instrumentation port in fluid communication with the exit port and first and second separately sealable access ports; a guiding catheter connected to the exit port; a first elongate element passing through the first access port and the guiding catheter; and a second elongate element passing through the second access port and the guiding catheter and being movable independently of the first element.
Claim 6
Independent Claim
76 words
An apparatus for use in angioplasty, comprising: a valve having an exit port, an instrumentation port in fluid communication with the exit port and first and second separately sealable access ports; a guiding catheter connected to the exit port; a first elongate element passing through the first access port and the guiding catheter; and a second elongate element passing through the second access port and the guiding catheter and being movable independently of the first element.
Claim 7
Dependent Claim
26 words
An apparatus as claimed in Claim 4 wherein the first elongate element comprises a dilation catheter and the second elongate element optionally comprises a guide wire.
Claim 8
Dependent Claim
49 words
An apparatus as claimed in claim 4 or claim 5 including at least one additional access port sealable independently of the other access ports and an elongate element passing through the or each additional access port and the guiding catheter and being movable independently of the other elongate elements.
Claim 9
Dependent Claim
112 words
A hemostatic valve, comprising: a body having an exit port, a central arm aligned axially with the exit port and a pair of side arms intersecting the central arm at an angle; an instrumentation port formed in one of the side arms in fluid communication with the exit port; a first sealable access port formed in the central arm for receiving a first elongate element which passes through the exit port; and a second access port formed in the second side arm and sealable independently of the first access port for receiving a second elongate element which passes through the exit port and can be manipulated independently of the first elongate element.
Claim 10
Dependent Claim
112 words
A hemostatic valve, comprising: a body having an exit port, a central arm aligned axially with the exit port and a pair of side arms intersecting the central arm at an angle; an instrumentation port formed in one of the side arms in fluid communication with the exit port; a first sealable access port formed in the central arm for receiving a first elongate element which passes through the exit port; and a second access port formed in the second side arm and sealable independently of the first access port for receiving a second elongate element which passes through the exit port and can be manipulated independently of the first elongate element.
Claim 11
Dependent Claim
50 words
A hemostatic valve as claimed in claim 7 including end caps threadedly mounted on the central arm and the second side arm with openings through which the elongate elements can pass, and sealing glands compressable about the elongate elements by roatation of the end caps to seal the access ports.
Claim 12
Dependent Claim
57 words
A hemostatic valve as claimed in claim 8 wherein each of the access ports includes an axial bore with a radially extending shoulder forming a seat for one of the sealing glands, and each of the end caps has an axially extending stem which extends into the bore and in use compresses the gland against the seat.
Claim 13
Dependent Claim
20 words
A hemostatic valve as claimed in claim 9 wherein the seat in each of the access ports is conically tapered.
Claim 14
Dependent Claim
26 words
A hemostatic valve as claimed in any one of claims 7 to 10 including a rotary connector for attaching a guiding catheter to the exit port.
Claim 15
Dependent Claim
72 words
A hemostatic valve as claimed in any one of claims 7 to 11 including at least one additional side arm which intersects the central arm, and a separately sealable access port formed in each additional side arm for receiving an elongate element which passes through the exit port and can be moved independently of the other elongate elements, the side arms optionally lying in planes which extend radially from the central arm.
Claim 16
Independent Claim
181 words
A method of assembling apparatus for coronary angioplasty comprising elongate elements, for example guide wires and dilatation catheters, and a hemostatic valve having an exit port and a pair of access ports, the method comprising: connecting the proximal end of a guiding catheter to the exit port; inserting a first elongate element through a first one of the access ports, the exit port and the guiding catheter with the distal end portion of the elongate element extending beyonding the distal end of the guiding catheter; forming a fluid-tight seal between the first elongate element and the first access port through the second access port, the exit port and the guiding catheter; said second elongate element being movable independently of the first elongate element; and forming a fluid-tight seal between the second elongate element and the second access port, the hemostatic valve optionally having at least three access ports, an independently movable elongate element being introduced through each of the access ports, and a fluid-tight seal being formed between each of the access ports and the elongate elements passing through the same.
Claim 17
Independent Claim
181 words
