  • Patent number: 5685858
    Abstract: A catheter gard unit is disclosed herein which includes a flexible tapered introduction guide. The distal end of the tapered introduction guide, in a sheath procedure, is placed over a guide wire and into a sheath, both of which have been pre-placed within a patient's body. In a sheathless procedure, the distal end of the tapered introduction guide is placed adjacent the skin of the patient and over the pre-placed guide wire. The gard unit comprises a body with a passageway therethrough for the passage of the catheter tube. A resilient slidable seal is mounted upon the tapered introduction guide of the gard unit. The slidable seal is adapted to slid over and seal the connection between the introduction guide, through which the catheter is placed, and a hemostasis valve of the sheath, after insertion of the sheath into the patient's body and thereby form a liquid seal between the introduction guide and the sheath.

  • Patent number: 4819752
    Abstract: A blood constituent measuring apparatus and method, which can be used to measure the oxygen (or other blood constituent) content of the blood. The apparatus includes sources of two or more wavelengths of light for transmitting, e.g., red and infrared light through a portion of the body, and a photodetector for generating respective signals representing each wavelength of light transmitted through the body portion. The photodetector signals have pulsatile and non-pulsatile components. The oxygen content of the blood is computed based on the light transmitted through the body portion at each wavelength, as determined from the pulsatile component, amplified alone after the much larger non-pulsatile component is subtracted from it. The apparatus can compute the oxygen content of patients with weak pulses, or unstable physiological states, or both, by using, preferably, a plurality of independently settable gains, to maintain the signal level within a range suitable for accurate measurement.

  • Patent number: 4631059
    Abstract: A hollow, open-ended sheath is removed from a position enclosing a catheter which has been inserted through the sheath with a close tolerance and introduced into a human body thereby. A cutting blade is mounted in a deforming and guiding mechanism connected to the blade and engageable with the sheath for exerting pressure on the sheath in such a manner as to deform the sheath away from the catheter at a point immediately adjacent to the cutting blade and into contact with the cutting blade while maintaining the catheter beyond the reach of the blade. The device guides the blade for lengthwise movement relative to the sheath. The blade cuts the sheath in a lengthwise direction for removal from the catheter while the catheter remains in place.
