Assignee:

Keimar Corporation - Los Altos CA

International Classification:

A61B 502

US Classification:

600526, 600345, 600348, 600364

Abstract:

Apparatus for ascertaining cardiac output of the heart of a patient comprising a control and display module. A venous probe is inserted into a vein in the forearm of the patient and is coupled into the control and display module and provides an electrical signal representing the dissolved oxygen in the venous blood. An arterial probe is inserted into an artery in the forearm of the patient and is coupled into the control and display module and provides an electrical output signal representing the dissolved oxygen in the arterial blood. The control and display module has a visible display that provides a continuous in vivo cardiac output that utilizes an arterial venous oxygen differential equation which includes an adjustment factor for adjusting for venous blood being sampled rather than mixed venous blood in the pulmonary artery of the patient.

US Classification:

600345, 600364, 600348, 600353, 600355, 600361

Abstract:

An apparatus for use with a patient having a vessel carrying blood to ascertain characteristics of the blood. The apparatus includes a display module and a probe having a distal extremity adapted to be inserted into the vessel of the patient and having a proximal extremity coupled to the display module. The probe includes a sensor in the distal extremity for providing an electrical signal to the display module when the probe is disposed in the blood. The probe can have an antithrombogenic surface treatment for inhibiting the adhesion of blood components to the probe when disposed in the blood.

International Classification:

A61B 1739

US Classification:

128898

Abstract:

The present invention provides electrosurgical needles, needle systems, and methods for their use which will allow the surgeon to target a tumor's blood supply. Generally, the invention facilities targeting the bloodflow of the tumor by incorporating a doppler ultrasound transducer into the needle or needle sheath. Preferably, the surgeon will also be able to control the temperature of the needle using an integral temperature sensor to effect maximum transfer of the RF energy into the tissue, thereby maximizing the volume of tissue destroyed. Furthermore, when used (for example) in the treatment of uterine fibroids, the present invention will reduce damage to the serosa by monitoring the uterine surface temperature during myolysis through a temperature sensor integrated into the sheath holding the myolysis needle.
