  • Patent number: 5167623
    Abstract: A multilumen catheter having a distal portion with a soft tip and reduced cross-section. The multilumen catheter of the present invention includes a flexible, elongated first catheter tube and a flexible, elongated, dual-lumen catheter tube which has a first and second lumens integrally formed and is disposed within the first catheter tube. The cross-section of the dual-lumen catheter tube is smaller than that of the first catheter tube and therefore, an independent, single lumen is defined in the space between the first catheter tube and the dual-lumen catheter tube. The dual-lumen catheter tube extends beyond the distal end of the first catheter tube thereby providing an overall reduced cross-section of the distal portion of the present multilumen catheter. Furthermore, the dual-lumen catheter tube may be formed from a softer material than that of the first cathether tube thereby providing a softer distal portion of the present multilumen catheter.

  • Patent number: 5149330
    Abstract: A catheter capable of being converted from a single lumen catheter into a multilumen catheter. The catheter of the present invention comprises a first large bore catheter tube and a second catheter tube having at least one lumen and an outer diameter which is smaller than the inner diameter of the first catheter tube and which is capable of being disposed within the first catheter tube. When the second catheter tube is disposed within the first catheter tube, the second catheter tube abuts a portion of the inner wall of the first catheter tube to form a single lumen between the inner wall of the first catheter tube and the outer wall of second catheter tube. The first catheter tube has a first connector portion at its proximal end which is mateable with a second connector portion at the proximal end of the second catheter tube.

  • Patent number: 5147336
    Abstract: An adapter kit 32 for a catheter introducer 31 wherein catheter 34 is passed into the body to transmit a medium through lumen 35 in catheter 34. Coupling means 95 is provided for compressing compression glands 48a and 48b against catheter 34 in a controlled manner in a catheter gripping position in FIG. 13, so that maximum resistance to catheter 34 pull-out is provided without distorting any medium transmitted by lumen 35. A related method is provided for sizing and using compression gland(s) 48.

  • Patent number: 5128101
    Abstract: A method of treating an article with a mixture of ethylene oxide gas, air, and an inert gas which makes possible reuse of the ethylene oxide for an indefinite number of successive treatment cycles. The gas mixture is refortified with ethylene oxide when necessary. Nonflammability is maintained by removing air from the treatment tank before the mixture is admitted into the tank by the evacuation of the tank to a predetermined pressure, the admitting of an inert gas to the tank to a predetermined pressure, and the subsequent removal of the resulting air and inert gas mixture from the tank by evacuation to a predetermined pressure, the air removal resulting in an air proportion less than or equal to that proportion residing in the treatment mixture that is maintained in the holding tank.
