| 20120136301 | Power Injection Valve - A device for transferring fluids between an internal structure in a living body and an exterior thereof comprises a housing including a pressure activated lumen extending to a distal end opening to a power injection lumen that extends to a distal port configured for connection to a fluid conduit extending to a target structure within the body and a pressure activated valve extending across the pressure activated lumen and controlling fluid flow therethrough, in combination with a proximal port coupled to the housing for movement between a first position in which a proximal end of the power injection lumen opens to the proximal port and a second position in which a proximal end of the pressure activated lumen opens to the proximal port. | 05-31-2012 |
| 20120130319 | Valved Catheters Including High Flow Rate Catheters - A pressure activated two-way slit valve assembly is designed to be used in combination with, but not limited to, a high flow rate catheter to prevent accidental ingestion of air or loss of blood if the closure cap comes off during non-use of the catheter. In addition, the potential for occlusion of the catheter due to blood clots in the catheter and catheter related infection is substantially reduced. The pressure activated two-way slit valve assembly includes a first end, a second end, a wall defining a dumbbell shaped channel, and a flexible, thin disk having a slit and positioned within the pressure activated two-way slit valve assembly to reside within the dumbbell shaped channel. The slit and the dumbbell shaped channel are sized to enable the slit to deform in response to a predetermined pressure differential across the slit to allow fluid to pass therethrough. | 05-24-2012 |
| 20120059250 | Power Injectable Port Identification - An implantable port for accessing internal body structures, the port comprises a proximal housing including an opening providing access to an interior of the port and a distal housing adapted for assembly with the proximal housing, the distal housing including a reservoir which, when the distal housing is mated with the proximal housing is in fluid communication with the opening of the proximal housing in combination with a radiopaque element in one of the proximal and distal housings, a shape of the radiopaque element identifying, when imaged, a structural characteristic of the port not otherwise identifiable visually. | 03-08-2012 |
| 20110313368 | Pressure Activated Valve with High Flow Slit - A pressure actuated valve for controlling the flow of fluid through a medical device, the valve comprises a housing including a lumen extending therethrough and a flow control membrane extending across the lumen to control the flow of fluid through the lumen. The membrane includes a plurality of slits extending therethrough so that, when the membrane is acted upon by a pressure of at least a threshold magnitude, the slits open to permit flow through the lumen and, when not acted upon by a pressure of at least the predetermined magnitude, the slits are maintained closed by a biasing force applied thereto by the membrane to prevent flow through the lumen. Each of the slits extends between end portions thereof along a curve wherein a distance between a first end portion of a first one of the slits and a first end portion of a second one of the slits is a minimum distance between the first and second slits. | 12-22-2011 |
| 20110313367 | PRESSURE RESPONSIVE SLIT VALVE ASSEMBLY FOR A PLURALITY OF FLUIDS AND USES THEREOF - A pressure responsive slit valve assembly is designed to be used in a variety of configurations of medical devices to manage contemporaneous and pressure responsive fluid communications between such devices and a plurality of fluid sources. The pressure responsive slit valve assembly of the present invention includes a valve housing adapted to receive fluids from at least two sources and a pressure responsive slit valve means corresponding to each fluid sources. | 12-22-2011 |
| 20110264054 | METHOD TO SECURE AN ELASTIC COMPONENT IN A VALVE - An apparatus for controlling fluid flow to provide long-term access to the vascular system, and methods of making the same, are disclosed. Exemplary embodiments of the present invention describe a wedge or other similarly shaped geometrical feature for fixing an elastic component and controlling an internal stress of the elastic component. | 10-27-2011 |
| 20110257608 | Multi-Slit High Flow Valve - A valve may include (a) a housing defining a valve lumen adapted for fluid connection with a lumen of a catheter; (b) a substantially conical valve member coupled to the housing and extending across the valve lumen to control flow therethrough; (c) a plurality of slits extending through the valve member and separated from one another circumferentially around the valve member; and (d) a ramp formed within a distal end of the valve lumen extending proximally from a distal tip of the valve member toward a ramp vertex separated from the distal tip by a predetermined distance. | 10-20-2011 |
| 20110118612 | Valved Catheter with Integrated Pressure Measurement Capabilities - Valve assemblies and valved catheters including pressure sensors, and related methods for treating patients, are disclosed. The valve assembly includes a valve member extending across a first lumen and includes a planar flexible member with an internal slit acting as a valve. The valve assembly further includes a pressure sensor located distally from the valve member and in fluid communication with the first lumen. | 05-19-2011 |
| 20110087093 | VALVE CONFIGURATIONS FOR IMPLANTABLE MEDICAL DEVICES - A medical device at least partially insertable into a patient. The device comprises a catheter portion comprising a flexible tube that is at least partially insertable into the patient, and a valve portion proximal to the catheter portion. The valve portion comprises a planar flexible member comprising first and second valve portions separated from one another by an internal slit. The thickness of the planar flexible member at the internal slit is less than the thickness of the planar flexible member at any other location. | 04-14-2011 |
| 20110071500 | BRANCHED CATHETER TIP - A venous access device comprises a catheter portion extending longitudinally from a proximal end to a distal end, the flexible shaft defining a lumen therein in combination with a plurality of branches separated from one another and extending distally from the flexible shaft. | 03-24-2011 |
| 20110009811 | METHOD TO SECURE AN ELASTIC COMPONENT IN A VALVE - A valve comprises a flexible member including a slit formed on a central portion thereof and a first housing defining a first lumen extending therethrough, the first housing including a first contacting surface adapted, when the slit of the flexible member is aligned with the first lumen, to contact a first side of the flexible member the first housing defining a relief area extending about a perimeter of the first contacting surface radially outside the central portion relative to a longitudinal axis of the first lumen in combination with a second housing adapted to mate with the first housing with a second lumen defined by the second housing aligned with the first lumen and separated therefrom by the flexible member, the second housing including a second contacting surface which, when the first and second housings are mated to one another in an operative configuration with the flexible member pinched therebetween, contacts a second side of the flexible member opposite the first side thereof along the longitudinal axis, a radially outer portion of the second contacting surface including a protrusion aligning with and extending into the relief area when the first and second housings are mated in the operative configuration, the protrusion bending a peripheral portion of the flexible member about a radially outer edge of the first contacting surface into the relief area to maintain the flexible member at a desired position separating the first and second lumens so that, when subject to a fluid pressure of at least a predetermined magnitude, the slit of the flexible member opens to permit fluid transfer between the first and second lumens and, when subject to a fluid pressure less than the predetermined magnitude, the slit of the flexible member remains closed preventing fluid transfer between the first and second lumens. | 01-13-2011 |
