Definitions

  • the subject of this invention is a vascular prosthesis assembly and particularly a prosthesis assembly incorporating a tubular graft .to be used for replacing a portion of a blood vessel in a human or animal body.
  • vascular prostheses are becoming more and more widespread in the treatment of certain biological conditions but at present such prostheses are merely substitutes for blood vessels.
  • a prosthesis has been inserted as a graft in a blood vessel there is no way of knowing what is act ⁇ ually happening in the blood vessel without actually making a surgical examination.
  • a vascular prosthesis assembly incorporates a tube' of textile material incorporating at least one transducer sensitive to at least one of the conditions to be monitored attached to the tube wall so that the sensitive portion of the transducer is exposed to the interior of the tube and a transmitting device to which the transducer is connected arranged to transmit a radio signal which carries information about conditions prevailing in blood passing through the prosthesis.
  • the prosthesis may incorporate several transducers each sensitive to a different characteristic.
  • transducer sensitive to blood pressure there may be incorporated a transducer sensitive to the pH value of the blood, there may be incorporated a transducer sensitive to temperature.
  • transducer sensitive to temperature There may be incorporated in the prosthesis . two transducers spaced axially from one another, one transducer being a sound-emitting transducer and the other transducer being a sound-receiving transducer and computing means capable of determining the rate of flow of blood through the prosthesis, for example by use of the d ⁇ ppler effect.
  • the transducers may be incorporated in the structure of the prosthesis or may be attached to the prosthesis by bio-compatible adhesive.
  • the signals produced by the transducers may be such that they can be picked up ' by a receiver located outside the body at a distance from the body or it may be arranged that they are picked up by a receiver located at another organ in the body, that receiver being arranged to stimulate that organ to operate in accordance with the signal received whereby to compensate for some undesirable effect or trend perceived by the transducer in the prosthesis.
  • transducers sensitive to characteristics to be monitored denotes transducers sensitive to characteristics to be monitored and 3 and 4 are two transducers one of which is capable of issuing a sonic signal and the other is capable of receiving a sonic signal.
  • 5 denotes computing means in the form of a micro-computer arranged to control operation of the transducers 3 and 4.
  • 6 denotes a radio transmitter arranged totransmit as radio signals the signals from the transducers and from the micro- computer.
  • the transmitter and the micro-computer are incorporated in a separate capsule which may be located at a remote point, for example the capsule may be located for convenience of access in a subcutaneous position.
  • the transmitter and the micro-computer may be located in separate capsules or in the same capsule which may be located on the graft or at another convenient site.
