Pressure activated safety valves have been incorporated into medical devices such as peripherally inserted central catheters (PICCs), ports, dialysis catheters and tunneled central catheters which provide long term access to the vascular system, etc. These valves generally include an clastic component that controls flow and/or pressure through the device to prevent flow therethrough when the device is not in use. The elastic component may be a slitted, flexible membrane extending across a lumen generally constructed so that, when subjected to a fluid pressure of at least a threshold magnitude, edges of the slit separate from one another to permit flow through the lumen. When the pressure applied to the membrane drops below the threshold level, the slit reseals to prevent leakage from or into the device. It is desirable to keep the flexible disk in place during high pressure and/or flow while maintaining the desired flow control characteristics of the membrane.
The present invention is directed to a valve comprising 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.
The present invention may be further understood with reference to the following description and the appended drawings, wherein like elements are referred to with the same reference numerals. The present invention relates to an apparatus for controlling fluid flow through medical devices specifically for sealing devices which remain in place in the body to provide long term access to the vascular system. To improve the performance of pressure activated safety valves, exemplary embodiments of the present invention describe a wedge or other similarly shaped geometrical feature for fixing an clastic component and controlling an internal stress of the elastic component.
As shown in
The elastic component 106 may be any flexible membrane (e.g., in the form of a disk) including a slit (not shown) for controlling fluid flow therethrough such as, for example, a silicone disk. The elastic component 106 may operate as a bi-directional valve allowing fluid to flow through the device 100 in either direction whenever the valve is subjected to a fluid pressure of at least a threshold value. Alternatively, the elastic component 106 may operate as a uni-directional valve allowing fluid to flow in only one direction or having different threshold values for each of the two directions of flow therethrough. The clastic component 106 is configured to open only when fluid pressure exerted thereagainst reaches a predetermined threshold magnitude. The slit opens via a deformation of the clastic component 106 with edges of the slit moving away from one another to allow fluid to flow therethrough. Once fluid pressure falls below the threshold magnitude, the slit reseals preventing fluid from flowing therethrough. It will be understood by those of skill in the art that the elastic component 106 may include more than one slit extending therethrough.
As shown in
The second housing 104 includes a lumen 116 extending therethrough and a disk-facing surface 118, which contacts the elastic component 106. The disk-facing surface 118 includes a substantially planar central portion 130 surrounding the lumen 116 and a protrusion 124 surrounding the planar central portion 130. The protrusion 124 extends distally away from the planar central portion 130 around a radially outer edge of the disk-facing surface 118. The protrusion 124 may be, for example, wedge-shaped including an angled surface 126 which contacts a radially outer portion of the elastic component 106 bending it over the edge 122 distally into the relief area 120. It will be understood by those of skill in the an that the protrusion 124 may extend continuously about the outer perimeter of the disk-facing surface 118 or may be formed as a series of protrusions separated from one another circumferentially about the outer perimeter of the disk-facing surface 118 by a series of recesses or gaps. In a preferred embodiment, the protrusion 124 is substantially ring-shaped and extends continuously around a circumference of the disk-facing surface 118.
The relief area 120 and the protrusion 124 of the first and die second housings 102, 104, respectively, enhance retention of the elastic component 106 applying compression to the elastic component 106 radially inward toward the longitudinal axis of the first and second housings 102, 104, respectively, to counteract tension to which the elastic component 106 is subjected as it is pinched between the first and second housings 102, 104 and stretched into the relief area 120. Initially, as the elastic component 106 is being pinched between the first and second housings 102, 104, as the outer edge of the elastic component 106 is bent around the edge 122 into the relief area 120, the central portion of the elastic component 106 is stretched radially outward drawing edges of the slit away from one another and puckering the central portion of the elastic component. Then, as the first and second housings 102, 104 are moved further toward one another, the elastic component 106 is pinched between the protrusion 124 and the edge 122 reducing a thickness of this portion of the elastic component 106 and urging the material pinched away from this area toward the slit—i.e., compressing the elastic component 106 radially to bring the edges of the slit back together sealing the valve. The planar portion 130 of the disk-facing surface 118 keeps the central portion of the clastic component 106 substantially flat so that the elastic component 106 does not pucker, aligning edges of the slit while under compression. In addition, the bending of the peripherally outer portion of the elastic component 106 over the edge 122 into the relief area 120 reduces the likelihood that the elastic component 106 will be pulled out of position between the first and second housings 102, 104 when subjected to excess pressure. That is, the outer perimeter 132 of the clastic component 106 extends radially outward of the edge 122 in the relief area 120 with the outer perimeter 132 acting as an anchor holding the elastic component 106 in place.
It will be understood by those of skill in the art that the compression force for closing the slit may be controlled by altering the angle of the angled surface 126 and a position of the protrusion 124 in relation to the edge 122. In a preferred embodiment, the angled surface 126 may be angled from between approximately 40E to 50E and more preferably, at an angle of approximately 45E. The location of the edge 122 may be determined by the angled surface 126, which is positioned to the periphery of the flexible member 106. Thus, the compression force may be controlled as desired. It will also be understood by those of skill in the art that the amount of compression on the slit and/or the elastic component 106 is one of the factors determining the pressure gradients needed to open and close the slit. Other factors may include, for example, a flexibility, a thickness, and a material of the elastic component 106.
It will be apparent to those skilled in the art that various modifications and variations may be made in the structure and the methodology of the present invention, without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided that they come within the scope of the appended claims and their equivalents.
