A method for using a biopsy device includes providing a housing containing a tension slide, wherein the tension slide is movable to a cocked position against the action of a spring by the power source; inserting a removable element into the housing, the removable element including a biopsy cannula unit, a pressure generating device, a first connection element connecting the biopsy cannula unit and the valve, and a second connection element connecting the valve and the pressure generating device; arranging the biopsy cannula unit on the tension slide; operating the pressure generating device to generate a vacuum; and operating the valve to control pressure buildup and release within the pressure generating device.

Quick cycle biopsy system

A method for operating a biopsy apparatus includes providing a cannula having a lumen, a proximal portion, a closed distal end, and an orifice located on a circumferential surface of the cannula, the orifice being configured to receive a tissue sample into the lumen of the cannula; providing a cutting sheath coaxially disposed with the cannula, the cutting sheath being configured to be movable relative to the cannula to selectively cover the orifice; providing a pressure chamber coupled to the proximal portion of the cannula, the pressure chamber configured to contain a pressure; providing a bifurcated valve assembly interposed between the cannula and the pressure chamber, the bifurcated valve assembly having a first valve and a second valve; operating the first valve to release the pressure into the lumen of the cannula; and operating the second valve to facilitate an inflow of air into the pressure chamber.

Method for operating a biopsy apparatus

A biopsy apparatus includes a cannula, a cutting sheath, and a pressure generating device. The cannula has a lumen, a proximal portion, a closed distal end, and an orifice located on a circumferential surface of the cannula. The orifice is configured to receive a tissue sample into the lumen of the cannula. The cutting sheath is coaxially disposed with the cannula. The cutting sheath is configured to be movable relative to the cannula to selectively cover the orifice. The pressure generating device is coupled to the proximal portion of the cannula. A bifurcated valve assembly is interposed between the cannula and the pressure generating device. The bifurcated valve assembly has a first valve configured to release pressure into the lumen of the cannula and has a second valve configured to facilitate an inflow of air into the pressure chamber of the pressure generating device.

The cutting sheath is configured to be movable relative to the cannula to selectively cover the orifice. The pressure generating device is coupled to the proximal portion of the cannula. A valve is interposed between the cannula and the pressure generating device. The valve is configured to control a flow of a fluid between the lumen of the cannula and the pressure generating device.

A method for extracting a tissue sample includes altering the pressure inside the lumen of a cannula to facilitate extraction of a tissue sample from the cannula. One aspect of the invention includes a biopsy apparatus comprising a valve for controlling the pressure inside the lumen of the cannula. In one variation, the pressure/vacuum generating device is connected to a cannula with a closed distal end and an orifice located on a circumferential surface of said cannula. A cutting sheath is slidably disposed over said cannula. The valve may be provided between the pressure/vacuum generating device and the cannula to control the pressure within the lumen of the cannula.

An implantable vessel filter having an integrated sensing capability for monitoring the condition of the vessel filter. In one variation, the vessel filter comprises a plurality of legs that would themselves perform as a sensor device for detecting distention, which would indicate the presence of a clot or thrombus therein. A passive electrical circuit may be implemented on the vessel filter to receive electromagnetic energy and transmit signals indicative of the condition of the implanted vessel filter. In another variation, a miniaturized sensor is adapted for measuring the strain and/or other physical parameters of the filter legs.

Vascular filter with sensing capability

A biopsy apparatus includes a cannula having a closed distal end. An orifice is located on a circumferential surface of the cannula. The orifice is configured to receive a tissue sample into a lumen of the cannula. A cutting sheath is slidably and coaxially disposed over the cannula. The cutting sheath is adapted to seal the opening of the orifice. A pressure generating device is connected to a proximal portion of the cannula for altering a pressure in the lumen of the cannula. A valve is positioned between the cannula and the pressure generating device for controlling a flow of a fluid between the lumen of the cannula and the pressure generating device.

A microporous reinforced expanded PTFE vascular graft in which the reinforcing structure is substantially identical in porosity to the body of the graft. The graft is characterized by a microporous expanded PTFE tubular graft wall and integral and monolithic expanded PTFE rib structures with a porosity or density substantially identical to that of the tubular graft wall.

A pacifier assembly including a distinct cover design having light emitting diodes located at the details of the cover design to provide entertainment to the viewer of the pacifier. One or more light emitting diodes are attached to the pacifier face plate and are activated by the use of the pacifier using a controller circuit and or a switch.
