International Classification:
A61B 17/3209, A61B 18/14
US Classification:
606 45, 606167
Abstract:
A surgical instrument guide for facilitating treatment of a target tissue is provided. The surgical instrument guide may be placed between two groups of tissue such that a first group of tissue is cut and a second group of tissue is protected from being cut. The surgical instrument guide may lift tissue and slide tissue along a surface so that a target tissue may be cut to a desired depth more easily during a surgical procedure. The surgical instrument guide may be releasably attachable to a surgical instrument or integrally formed therewith.

International Classification:
A61M 1/14, A61M 37/00, C02F 1/44, B01D 53/22
US Classification:
422 44, 604 401, 604 609, 604 614, 210645, 216DIG 28
Abstract:
A disposable, integrated extracorporeal blood circuit employed during cardiopulmonary bypass surgery performs gas exchange, heat transfer, and microemboli filtering functions in a way as to conserve volume, to reduce setup and change out times, to eliminate a blood reservoir, and to substantially reduce blood-air interface. Blood from the patient or prime solution is routed through an air removal device that is equipped with air sensors for detection of air. An active air removal controller removes detected air from blood in the air removal device. A disposable circuit support module is used to mount the components of the disposable, integrated extracorporeal blood circuit in close proximity and in a desirable spatial relationship to optimize priming and use of the disposable, integrated extracorporeal blood circuit. A reusable circuit holder supports the disposable circuit support module in relation to a prime solution source, the active air removal controller and other components.

International Classification:
G01N 29/00
US Classification:
73 1903
Abstract:
A universal air bubble detector allows for use with a variety of sizes and types of tubing. The detector maintains proper alignment of a sensor emitter and receiver with different sizes of tubing. The detector may be mounted on existing equipment or may be used to monitor a tubing at any position along the tubing, and may operate in a stand alone mode or in combination with existing equipment.

Automatic Safety Occluder
US Patent:
8491543, Jul 23, 2013
Filed:
Jul 22, 2011
Appl. No.:
13/188818
Inventors:
Mark Stringham - Salt Lake City UT, US
Assignee:
Zevex, Inc. - Salt Lake City UT
International Classification:
A61M 5/00, A61M 1/00
US Classification:
604250, 604151, 251 4, 251 6
Abstract:
An automatic safety occluder provides an occluder for an infusion set that is biased in a closed position until an electrical signal is received that causes the occluder to open. Should the occluder fail to be installed correctly, or if power is removed, the occluder will return to its biased closed position, preventing free flow. The occluder may also be placed in an integrated unit such that the automatic safety occluder may attach to the tubing as a unit.

Pressure Sensor And Method Of Use
US Patent:

Filed:

Assignee:
Zevex, Inc. - Salt Lake City UT
International Classification:
A61M 5/142
US Classification:
604151, 604 9301
Abstract:
A sensor and method of use provides for detection of an occlusion (or sudden pressure increase) in tubing during the administration of solutions to a patient. The occlusion sensor may be attached to an infusion pump using a biasing mechanism. The tubing may be positioned in contact with the occlusion sensor using a cassette. Detection of an occlusion in the tubing is accomplished by measuring the compression and expansion of the tubing. When the tubing becomes occluded pressure within the tube will increase, resulting in expansion of the tubing. Expansion of the tubing exerts a force on the sensor to trigger an alarm to alert medical personnel of the occluded tube.

Assignee:
Zevek, Inc. - Salt Lake City UT
International Classification:
G01N 29/00
US Classification:
73 182
Abstract:
Air bubbles may be characterized by an air bubble detector by choosing an optimum set of frequencies and then comparing a return signal from a sensor receiving those frequencies against an internal reference. The number of pulses that exceed the internal reference represents a width and may be counted. The width, as counted, may be correlated to bubble characteristics including volume.
