Abstract
Abstract A valved connector for a device for penetrating the arterial system of a patient. The connector comprises a tubular housing having a bore, plus a first valve for controlling back leakage through the tubular housing bore. The first valve is adjustably openable and closable to permit an elongated member to pass through the lumen of the first valve and bore of the housing, with the first valve providing selectively controllable sealing about the elongated member. A second valve is carried, typically proximal of the first valve. The second valve comprises a slit, resilient partition permitting the elongated member to pass through the slit partition with added sealing. Thus, back leakage through the housing can be controlled by the second valve when the first valve is opened, so that the elongated member passing through the connector can be easily moved by releasing the first valve without significant back leakage, so that the elongated member may be easily moved through the connector, but may be strongly sealed at any desired time.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
110 words
A valved connector for a device for penetrating the arterial system of a patient, which comprises: a tubular housing having a bore; a first valve for controlling back leakage through said tubular housing bore, said first valve being adjustably openable and closable to permit an elongated member to pass through the bore of said first valve while providing selectively controllable sealing about said elongated member; and a second valve carried proximal of said first valve, said second valve comprising a slit, resilient partition permitting said elongated member to pass through said partition with added sealing, whereby back leakage through said housing can be controlled when said first valve is opened.
Claim 2
Dependent Claim
110 words
A valved connector for a device for penetrating the arterial system of a patient, which comprises: a tubular housing having a bore; a first valve for controlling back leakage through said tubular housing bore, said first valve being adjustably openable and closable to permit an elongated member to pass through the bore of said first valve while providing selectively controllable sealing about said elongated member; and a second valve carried proximal of said first valve, said second valve comprising a slit, resilient partition permitting said elongated member to pass through said partition with added sealing, whereby back leakage through said housing can be controlled when said first valve is opened.
Claim 3
Dependent Claim
20 words
The connector of claim 1 in which a branch conduit connects with said tubular housing distal to said first valve.
Claim 4
Dependent Claim
44 words
The connector of claim 1 in which said first valve comprises a resilient, tubular valve member having a lumen that communicates with said bore, and a rotatable, screw-threaded pressure member to adjustably compress said resilient valve member to control the diameter of said lumen.
Claim 5
Dependent Claim
16 words
The connector of claim 1 which carries on its distal end a rotatable luer lock connector.
Claim 6
Dependent Claim
22 words
The connector of claim 1, attached to the proximal end of an elongated member having a size of at least French 9.
Claim 7
Dependent Claim
184 words
A valve connector for a device for penetrating the arterial system of a patient, which comprises: a tubular housing having a bore; a first valve for controlling back leakage through said tubular housing bore, said first valve defining a lumen and being adjustably openable and closable to permit an elongated member to pass through the lumen of said first valve and the bore of said housing, with said first valve providing selectively controllable sealing about said elongated member; and a second valve carried by a rotatable, screw-threaded pressure member in a position proximal of said first valve, said second valve comprising a slit, resilient partition permitting said elongated member to pass through said partition with added sealing, whereby back leakage through said housing can be controlled when said first valve is opened, said first valve comprising a resilient, tubular valve member having said lumen that communicates with said bore, said rotatable, screw-threaded pressure member being positioned to adjustably compress said resilient valve member to control the diameter of said lumen; and a branch conduit connecting with said tubular housing distal to said first valve.
Claim 8
Dependent Claim
184 words
A valve connector for a device for penetrating the arterial system of a patient, which comprises: a tubular housing having a bore; a first valve for controlling back leakage through said tubular housing bore, said first valve defining a lumen and being adjustably openable and closable to permit an elongated member to pass through the lumen of said first valve and the bore of said housing, with said first valve providing selectively controllable sealing about said elongated member; and a second valve carried by a rotatable, screw-threaded pressure member in a position proximal of said first valve, said second valve comprising a slit, resilient partition permitting said elongated member to pass through said partition with added sealing, whereby back leakage through said housing can be controlled when said first valve is opened, said first valve comprising a resilient, tubular valve member having said lumen that communicates with said bore, said rotatable, screw-threaded pressure member being positioned to adjustably compress said resilient valve member to control the diameter of said lumen; and a branch conduit connecting with said tubular housing distal to said first valve.
