Definitions
- This invention relates to the surgical manage ⁇ ment of body fluid accumulation, as in ascites and hydro ⁇ cephalus, and in particular provides a non-clogging, valved drainage system useful in draining accumulated body fluids, for example, as a peritoneo-venous shunt for draining ascites fluids into the venous system.
- Both ascites and hydrocephalus are serious maladies which are characterized by the accumulation of fluid, in one case in the peritoneal cavity, and in the other in a ventricle of the brain. It is known that both of .these conditions can be managed surgically by implanting a pressure-sensitive valve in the body which is .arranged to drain the accumulated fluid from the peritoneal cavity into a vein, such as the jugular vein, in the case of ascites and from the brain into the peritoneum in the case of hydrocephalus.
- a pressure-sensitive valve in the body which is .arranged to drain the accumulated fluid from the peritoneal cavity into a vein, such as the jugular vein, in the case of ascites and from the brain into the peritoneum in the case of hydrocephalus.
- a pressure-sensitive valve in the body which is .arranged to drain the accumulated fluid from the peritoneal cavity into a vein, such as the jugular vein, in the case of ascites and from
- a peritoneo-venous shunt patients occasionally-undergo occlusion of the valve system. This occurs with about 12% of such patients.
- occlusion is caused by small flecks of . inflammatory exudate formed within the peritoneal cavity which are transported upwardly and lodge in the valve itself cementing the surface of the valve.
- fibrinoid material or a small fat globule can prevent the valve from rising above its seat by mechanical interference with such action.
- a clot can form at the very tip of the tubing enter ⁇ ing the venous system which prevents egress of ascites fluid through the venous (distal) end of the system which lies in the superior vena cava.
- a flushing chamber that is a variable volume chamber on the intake side of the con ⁇ ventional, normally closed pressure-sensitive valve used to control drainage.
- This variable volume chamber has at least a flexible wall which can be located at a position where it can be manipulated by external pressure.
- a second valve which is flow- sensitive, as distinguished from pressure-sensitive, and which is normally open is located on the intake side of the system such that the variable volume flushing chamber is located between the two valves.
- variable volume flushing chamber is physically part of the valve housing for the pressure-sensitive valve.
- the valve housing is preferably located in the peritoneum, has its intake side, including the normally open, flow-sensitive valve, located inside the peritoneal cavity and has its dis ⁇ charge side placed external to the peritoneum and transversus and transversalis fascia. External manual pressure can thus be applied to the valve housing to flex the wall of the flushing chamber to decrease the volume of the chamber. This action closes the flow- sensitive valve, opens the pressure-sensitive valve and forces fluid through the discharge system. When pressure is released the pressure sensitive valve immediately closes thus preventing blood from being drawn into the system.
- FIG. I is a perspective view of a valved drain ⁇ age system in accordance with this invention.
- FIG. 2 is a transverse section through the system of FIG. 1 taken at line 2-2 in FIG. 1.
- FIG. 3 is a schematic drawing illustrating the placement of a valved drainage system in accordance with this invention in the treatment of ascites and
- FIG. 4 is a fragmentary view similar to FIG. 2 illustrating a modification in the location of the flushing chamber.
- System 10 includes a first valve housing 20 having a valve element 21, a flexible flushing chamber 40 and a second valve housing 50 having a valve element 51.
- Valve housing 20 is formed of injection molded polypropylene. Housing 20 is generally in the form of a flat cylinder 23 which is closed at its upper end, as is seen in FIGS. 1 and 2, by a concave portion 22. Its cylindrical sidewall 23 has a single- castellated nipple 24 providing external communication to the interior chamber 25 of housing 20 through a bore 26 in hippie 24.
- valve housing 20 As seen in FIG. 2, is closed with an annular member 27 which interconnects sidewall 23 and the upper portion of a depending cup-shaped base member 28.
- annular member 27 which interconnects sidewall 23 and the upper portion of a depending cup-shaped base member 28.
- OMPI cup-shaped member 28 carries a depending hollow tube 29 which is tapered to a closed lower end from which extends a castellated nipple * 30.
- Nipple 30 has a bore 31 communicating with the hollow interior of tube 29 and thence through cup 28 to the interior 25 of valve housing 20. Nipple 30 is set at a downward angle of approximately 60° from the vertical, as seen in FIG. 2. The upper end of tube 29 projects upwardly in cup 28 forming a valve seat 32.
- valve element 21 is formed of silicone rubber and includes as an integral unit a conical closure element 36 for seating on valve seat 32.
- Four arms 37 extending outwardly from the upper end of conical element 36 and terminating in a circum ⁇ ferential ring 38 form a resilient spider arrangement supporting valve element 21 with ring 38 firmly re ⁇ ceived in channel 35.
- the resiliency of arms 37 is such that only a small positive pressure differential on the underside of element 21 is required to lift conical closure element 36 off seat 32. This pressure is desirably on the order of 3 to 5 centimeters of H 2 0.
- Flushing chamber 40 is preferably made of silicone rubber and is formed as a cap which fits over the upper side 22 of valve housing 20 grasping side wall 23 with a depending cylindrical skirt 41 which is apertured at 42 to receive nipple 24.
- the top of flushing chamber 40 is in the form of a flat, closed' chamber 45 having a lower sidewall 43 lying against top 22 of valve housing 20 and an upper sidewall 44.
- the volume of chamber 45 is variable by flexing top wall 44.
- a bore 46 is provided in flushing chamber 40 for external communication with chamber 45.
- a small tube 47 of silicone rubber is affixed in bore 46 and extends around sidewall 41 of pumping ch.amber 40 through an opening 39 in tubular portion 29 of the bottom of valve housing 20. Tube 47 is affixed in opening 39 and thus provides a per ⁇ manent connection communicating the interior 45 of flushing chamber 40 with the interior of tube -29.
- a collar 12 of foamed silicone rubber having a notched rim 13 is secured over tube 29 firmly against the underside of cup 28 and is appertured at 15 to receive tube 11.
- Second valve housing 50 is made of injection molded polypropylene and has a central bell-like portion 52 enclosing a valve ⁇ hJamber 53.
- the wider end of portion 52 the lower end as seen in FIGS. 1 and 2, carries a castellated nipple 54, and the narrower, upper, end of bell portion 52 carries a castellated nipple 55.
- Nipples 54 and 55 are gener ⁇ ally coaxial with each other and with the axis of bell-like portion 52
- Nipple 54 has an internal bore 56 communicating with chamber 53
- nipple 55 similarly has a bore 57 communicating with chamber 53.
- Valve element 51 is formed of silicone rubber tapering from a flanged circular base 58 to a pair of flat lips 59 which are slightly parted under normal conditions and which close together upon any reverse flow.
- OMPI end of bell portion 52 is provided with a coaxial, internal, annular groove 60 adjacent bore 56 which is designed to receive flanged base 58 of element
- the apparatus is assembled together with a tube of silicone rubber 14 fitting over castellated nipples 30 and.55. holding the discharge side of valve 51 in communication with the interior of tube 29 and hence with the interior of flushing chamber 40 and the intake side of valve 21.
- Drainage device 10 can be used, for example, in the control of ascites, as seen more clearly with reference to FIG. 3, by connecting a section of fenestrated tubing 16 to nipple 54. Device 10 is then partly introduced through an opening made in the peritoneum with collection tubing 16 located within the peritoneal cavity, with collar 12 affixed in the opening in the peritoneum and with the mem ⁇ brane itself being closed about notch 13 such that the bulk of valve housing 20 and flushing chamber 40 are located on the exterior of the peritoneum and transversus and transversalis fascia.
- a section of silicone rubber tubing 17 is affixed over nipple 24 and carried up to the jugular vein, indicated by the reference letter J, through which it is introduced and carried down toward the superior vena cava, V.C. where it terminates.
- valve 21 Since valve element 51 is normally open, valve 21 functions in the arrangement depicted in FIG. 3 in the same manner as described in the above noted LeVeen patent No. 3,910,283.
- the pressure of fluid in the peritoneal cavity is of course transmitted through normally open valve element 51 and tube 11 into in- - ⁇ terior 45 of flushing chamber 40 such that interior 45 is normally filled with ascites fluid.
- valve 21 When chamber interior 45 is refilled functioning of valve 21 resumes in its normal manner.
- FIG. 4 illustratesa modified construction of more simplified design producing essentially the same functions as described with respect to device 10.
- System 70 designates a valved drainage system in accordance with this in ⁇ vention.
- System 70 includes a valve housing 80 formed of injection molded polypropylene of generally flat cylindrical shape having a flat closed upper end 81 and a cylindrical side wall 82 from which a castellated nipple 83 projects.
- Housing 80 also has a bottom end closure in the form of an outer annular flat portion 84 which retains a shallow cup-shaped bottom portion 85 having a central opening 86 formed by a short tubular upperwardly projecting portion 87 functioning as a valve seat.
- Annular bottom portion 84 also is interiorally provided with a pair of annular bosses 88 and 89 which form a groove 90.
- Tubular portion 87 also functions to provide fluid communication through opening 86 into the interior 92 of valve housing 80.
- a bore 91 in nipple 83 provides external fluid communi ⁇ cation to interior 92 of housing 80.
- Valve housing 80 is further provided with a short depending skirt 93 aligned with cylindrical side wall 82 which is provided with an external annular groove 94.
- valve element 95 identical with valve element 21 has a conical closure element 96 on its lower end and carries four arms 97 radiating from its- upper end and terminating in a peripheral rim 98.
- Valve element 95 is positioned in interior 92 of housing 80 such that rim 98 is firmly secured in groove 90 with closure element 96 seated against valve seat 87.
- the re- siliency of arms 97 and the location of the various components is such that, as in the case of valve element 21, valve element 95 is lifted off its seat 87 by a small positive differential pressure on the underside of closure element 86 of the order of 3 to 5 centimeters of H-O.,
- Valve 95 in valve housing 80 functions in the same manner as the.valve 21 described with are ' ference to FIGS. 1 and 2.
- the flow-sensitive valve is formed in a unitary silicone rubber bottom cap 100 which also functions in cooperation with bottom closure on valve housing 80 to define a flushing chamber 110.
- Cap 100 which is inverted in the normal sense of a cap, as shown in FIG. 4 has a generally annular flat bottom 101 with an upstanding peripheral sidewall 102 having an internal annular bead 103 positioned such that cap 100 can be snapped onto the bottom of valve housing 80 with bead 103 received in. groove 94.
- Bottom 101 of cap 100 is also provided with a depending tubu ⁇ lar leg 104 which is offset at approximately 45° from a vertical axis through housing 80, as seen in FIG. 4.
- a normally open valve element 105 Integrally moulded with leg 104 and bottom 101 is a normally open valve element 105 having a con- figuration similar to that of valve element 51.
- the lower end of valve element 105 is of generally circular cross-section and tapers inwardly up to a pair of opposing flat lips 106 -which are normally slighly parted.
- fluid flow is permitted in a direction upwardly through valve element 105, as seen in FIG. 4. Reverse flow will, however, immediately cause lips 106 to close together sealing valve element 105.
- lips 106 in the normal undistorted position of cap 100 are positioned approximatley in opening 86 leading into valve seat 87 such that free fluid communication between the interior 110 of cap 100 forming the flushing cha ⁇ ber is permitted around valve element 105 into valve seat tube 87.
- valved. drainage device 70 is essentially the same as that of device 10 except that the collection tubing system is positioned inside tube 104.
- the discharge tubing 17 is, of course, fitted over castellated nipple 83.
- the mem ⁇ brane of the peritoneum is located about tubing 104 such that valve 105 is actually located outside the peritoneal cavity, as distinguished from valve 51 which is located inside the peritoneal cavity.
- valve housings 20, 50 and 80 have been described as though they were single piece constructions. Obviously, this is not the case, and such constructions must be made of several parts fitted together with fluid-tight joints. Similarly, joints and connections, such as the fitting of rim 98 in groove 90 and other joints between separate parts must be mechanically secure and in most cases obviously must also be fluid-tight.
- chemically inert sealants such as silicone adhesives, can be employed.
- parts are indicated to be polypropylene, other rigid, chemically inert materials can be used.
- parts are indicated to be silicone rubber, other flexible, chemically inert elastomers can be used.
