Appl. No.:

11/014037

Inventors:

Gary Douglas - Billerica MA, US
David Regan - Pelham NH, US
Nilendu Srivastava - Chelmsford MA, US
Rachana Suchdev - Nashua NH, US

Assignee:

Vascular Technology Incorporated - Nashua NH

International Classification:

A61B 8/14

US Classification:

600459, 600453, 600455

Abstract:

A system is disclosed for the detection of blood flow. The system provides, a portable transceiver unit having a signal generator, a signal comparator, and an audio output whereby a user receives an audio signal indicating differences in Doppler signal, and a Doppler probe coupled to the portable transceiver. The Doppler probe including a piezoelectric crystal disposed at a first end of the Doppler probe; at least one wire transmitting signals between the transceiver unit to the piezoelectric crystal; a rigid or flexible sheath disposed around at least part of the at least one wire and the piezoelectric crystal; and a transceiver unit coupler disposed at a second end of the Doppler probe. The system may also have a quantitative blood flow meter or signal strength meter.

A61M 3/02

US Classification:

604 31, 604 30, 604 27, 604 35, 604 34

Abstract:

A system for the movement of fluids into and out of a surgical field is provided with a control module manipulated by a user; a valve controlled by the user via the control module, the valve controlling flow of a fluid; and a tube set having a proximal branch and a distal branch, wherein the proximal branch is opened and closed by the valve and at least a portion of the distal branch being flexible and a distal tip of the distal branch configured for manipulation within a surgical field. The valve is disposed at a distance to the surgical field and allows free access to tube by the user. Separate proximal branches for suction, irrigation, and insufflation are provided. One or more distal branches may be provided.

Abstract:

A cargo transport system is provided that has an ability to move cargo in an autonomous or semi-autonomous manner, using a compact lift vehicle capable of lifting relatively heavy objects. The system includes a cargo loading system, a sensor suite coupled with a controller, dunnage detection, cross-decking capability, cargo stacking capability, autonomous navigation, tip detection and prevention, or any combinations thereof. The system may include a fork assembly coupled with a mast and movable in a vertical direction relative to the mast. Further, the mast may be coupled with a platform or deck and movable in a horizontal direction relative to the platform, to allow the fork assembly to be lowered below a top plane of the platform when the mast is at a forward location relative to the platform. The controller and sensor suite and may provide for autonomous or semi-autonomous control and movement of the cargo transport system.
