Patent CA-2303692-A1 (CA)
Inventor: PAOLITTO ANTHONY
IPC: A61B17/04
Filed: 2000-04-05
Abstract: The present invention provides an improved surgical loop for constricting or ligating, partially or fully, an anatomic conduit during a surgical intervention. The surgical loop is preferably comprised of an elastomeric tubular body, a curved needle that is attached to one free end of said tubular body to facilitate its insertion through a body tissue containing an anatomic conduit, and a pledget which is frictionally engaged and positionable along the length of said tubular body. Pledget is frictionally engaged with a first portion of tubular body through a closed-perimeter opening, thereby forming an integral assembly with said tubular body. A second portion of tubular body is subsequently frictionally engaged or restrained with pledget through a slot configured therein. Pledget cooperates with a length of tubular body, between said first and second pledget-engaged portions, to constrict an anatomic conduit. The pledget is preferably configured with a bias means which maintains said slot in a biased-closed configuration, thereby frictionally engaging and restraining said second portion of tubular body. Bias may be overridden to entrain slot into an open configuration tending to facilitate the insertion of a second portion of tubular body without having to stretch or otherwise deform the tubular body to place it into engagement within said slot. Slot resumes its biased-closed configuration, thereby frictionally engaging and restraining the inserted second portion of tubular body. Tubular body may be drawn through either of slot or closed-perimeter opening to readjust the imposed constriction on anatomic conduit without having to disengage and re-engage second portion of tubular body from said slot.

Abstract: A cyclically operable system consecutively dispenses an equal volume of a liquid from a storage tank. The system includes a hermetically sealed metering chamber at least partially submerged beneath a standing level of liquid contained in a storage tank. The metering chamber has an inlet port communicating with the interior of the tank. A one-way valve accomodates an inflow of liquid into the metering chamber from the tank via the inlet port, and blocks an outflow of liquid from the chamber to the tank. A discharge conduit protrudes into the interior of the chamber. A pump or the like pneumatically pressurizes the metering chamber to thereby exhaust a predetermined volume of liquid via the discharge conduit. The metering chamber is then vented to accomodate an inflow of an equal volume of liquid via the inlet port.
