Filed:

Jul 6, 2001

Appl. No.:

09/900682

Inventors:

Jeffrey Carlisle - Rings Island MA, US
Peter Costa - Winthrop MA, US
Christopher Holmes - Harvard MA, US
John Kirkman - Kingston NH, US
John Thompson - San Clemente CA, US
Mark Semler - Bradford MA, US

International Classification:

F04B043/00

US Classification:

417/479000, 417/480000

Abstract:

A cassette for controlling fluid flow from a source to a sink, for example, a patient. The cassette comprises a housing, and a passive inlet valve for hydraulically controlling pressurized fluid flow from the inlet valve to a central chamber, and an actuatable outlet valve. The central chamber provides a fluid pathway between the inlet and outlet valves. The cassette further comprises a piston assembly for exerting pressure in the central chamber. The piston assembly comprises a movable member, a covering for the moveable member; and a flexible interface between the member and the housing for providing near frictionless movement between the member and the housing.

International Classification:

A61B 34/00
A61B 34/30
A61B 1/005

Abstract:

An articulating joint comprising a multi-cluster joint where every consecutive pair of links is interfaced by a gimbal, which offers rotation about two orthogonal axes within the same plane. Thus, the articulating joint comprises an alternating sequence of links and gimbals. Furthermore, there may be multiple cables attached to one or more of the links. As these cables are selectively pulled and released, one can achieve any desired articulation of the articulating joint. There may be a transmission member extending through the links and gimbals, parallel to the central longitudinal axis of the joint in its nominal non-articulated condition. This transmission member may be either a tension member that is pulled on (e.g. a cable or flexible pull rod) and that loads the articulating joint in compression, or the transmission member may be a flexible push rod that loads the articulating joint in tension.
