Abstract: An implantable treatment device has a housing portion defining a chamber and a self-resealable cover portion which closes off the chamber to provide a fluid receiving reservoir. An exit port extends from the reservoir to the external surface of the housing, and a locking member affixed to the device permits a twist-lockable catheter connection to be securely sealed to the exit port. In one embodiment the locking member is a base plate having a slot therein to capture the flange of a catheter connection. A protruding tab on the catheter connection may be sutured to hold the twist-locked connection in a fixed orientation. A multi-reservoir and multi-catheter embodiment is shown. A preferred implantable multi-reservoir device includes tactile features palpable through the skin for distinguishing the different reservoirs, or identifying the contents thereof.

Abstract: An integrally formed single piece loop ostomy appliance includes a central rod portion, a cross piece transverse to the rod portion at one end, and a displaceable end piece at the other end, displaceable between a first position which extends in the same general direction as the rod portion and a second position transverse to the rod portion. The end piece comprise a catch disposed to be in locking engagement with a recess in the rod portion when the end piece is moved to the second position. The end piece further comprises first and second spaced apart walls partially forming an aperture and adapted to be squeezed toward one another to release the catch from the recess. The loop ostomy appliance is preferably made of plastic, e.g. polypropylene.

Abstract: The invention is an improved attachment strap for a large diaper or adult incontinent pad. It consists of an accordion pleated length of material, preferably a nonwoven fabric, with one end permanently attached to the diaper body. The final pleat at the opposite end is terminated by a length of peelable pressure sensitive tape which overhangs each edge of the pleat. The medially oriented overhang is relatively narrow while the laterally oriented overhang, which ultimately serves as an attachment tab, is relatively wider. When in stored position, the two overhanging portions hold the folded tape compactly against the back face of the diaper where they do not interfere with manufacturing or packaging operations. The peelable attachment tape has an adhesive coating that is relatively high in shear strength but modest in peel strength. These characteristics are chosen so that the tape can be peeled off without tearing the diaper backing sheet.

The main body has at least one passage for use in joining the passage of the extension tube to the lumen.

Abstract: A gastrostomy-jejunal feeding tube comprises a gastrostomy tube having an enlarged resiliently, collapsible retainer element on the distal end thereof and a jejunal feeding tube which is removably received in the gastrostomy tube in a manner which allows fluids to pass through the gastrostomy tube despite the presence of the jejunal feeding tube therein. The gastrostomy-jejunal feeding tube is adapted to be installed in a patient so that the gastrostomy tube extends through the stomach wall, fascia and skin for draining fluids from the stomach and so that the jejunal feeding tube extends into the jejunum area of the intestines for feeding and medicating the patient. Since the jejunal feeding tube is removable from the gastrostomy tube it can be replaced without surgery, and since the retainer element is resiliently collapsible, it can be pulled outwardly through the stomach wall to allow the gastrostomy tube to be removed from the patient without surgery.

Abstract: A modular, portable water-jet system for attachment to the faucet of a kitchen or bathroom sink. The system includes a diverter valve assembly that can be screwed to the faucet and which has one outlet having an aerator and another outlet to which is removably attached a control valve assembly to which is removably attached a jet-flow device, such as an oral cleaning nozzle. The diverter valve assembly includes a spool valve slidably mounted in the housing. One end of the spool valve forms a passage from the inlet of the housing leading to the outlet port to the control valves assembly. A modular solution mixing and metering container can be optionally positioned between the diverter valve assembly and the control valve assembly when a liquid medicant or cleaning agent, for example, is desired. A cross-channel at the top of the container opens to the container where water mixes with and pressures the resulting mixture up a vertical pipe back to the cross-channel where it is pressured to the jet-flow device.

Abstract: A disposable "third hand" holder for CAPD exchange sets holds a set connector and a cap in an aseptic condition until ready for use. The holder is adhesively secured to a work surface. After the set connector has been removed from the holder and the exchange is under way, a sterilant tube can be connected to the holder in place of the set connector, and its contents can be squeezed out through a passage within the holder into the interior of the cap. When the patient's catheter is eventually capped, the sterilant in the cap maintains all interior surfaces of the catheter connector in an aseptic condition.
