Patent number: 5685858Abstract: 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.Type: GrantFiled: May 17, 1995Date of Patent: November 11, 1997Assignee: Datascope Corp.Inventor: John George Kawand

Patent number: 4819752Abstract: 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.Type: GrantFiled: October 2, 1987Date of Patent: April 11, 1989Assignee: Datascope Corp.Inventor: Michael P.
