  • Publication number: 20070179403
    Abstract: The invention relates to a coaxial cannula for extracting samples from tissue comprising a biopsy needle unit provided with a space for sample extraction and a sample separation unit which coaxially encompasses the biopsy needle on an external wall and is longitudinally movable. The inventive coaxial cannula comprises a sealing element which is arranged on the proximal end thereof and closes the space between the internal wall of the coaxial cannula and the external walls of the sample separation unit. The sealing element opens an air outlet when the biopsy needle unit is inserted, and prevents air intake when the biopsy needle unit is positioned and vacuum is produced in the internal chamber of the biopsy needle.

  • Publication number: 20070158147
    Abstract: The invention relates to pressure generating units, in particular to pressure generating unit arranged in the hand piece of a vacuum biopsy device in the form of a singe (2). In said units, air intake is open by a piston when said piston (5) is in the rear position thereof in the space of a vacuumed cylinder (11) which is switched for generating a superpressure, thereby initiating the outflow of a tissue liquid by the air introduced into the space of the vacuumed cylinder. For this purpose, the space of the vacuumed cylinder is connected to the space of an atmosphere pressure cylinder (12) arranged behind the piston, by means of a connection line (15), and an absorbing element (14) is placed on the piston axis.

  • Publication number: 20070149895
    Abstract: 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.

  • Publication number: 20070149894
    Abstract: A biopsy device for taking tissue samples, includes a housing, a removable element and a control panel. The housing contains an electric power source and a tension slide connected to the power source. The tension slide may be brought into a cocked position against the action of a spring by the power source. The removable element is configured for insertion into the housing and includes a biopsy needle unit, a vacuum pressure-generating device and a control panel. The removable element may be provided as a sterile package unit. The biopsy needle unit can be arranged on the tension slide and includes a hollow biopsy needle with a sample removal chamber and a cutting sheath. The biopsy device can be held in one hand and is fully integrated with all components required to perform a vacuum biopsy such that no cables or lines are required to other external units.

  • Publication number: 20070129717
    Abstract: Embodiments of the invention relate to electrophysiology catheters and methods of using the same. According to one embodiment, the catheter includes a braided conductive member at its distal end that can be radially expanded, for example using a mandrel slidably disposed within a shaft of the catheter. According to another embodiment, the catheter comprises a tip portion constructed of an elastomeric material. According to a further embodiment, the catheter includes a braided conductive member wherein a thermocouple is formed using one filament of the braided conductive member and one thermocouple wire. Other embodiments of the invention relate to a handle for use with a catheter and methods of using the same. According to one embodiment, the handle comprises a thumbwheel coupled to a housing, a spring disposed within the housing in contact with the thumbwheel, and means for increasing compression of the spring to increase rotational friction on the thumbwheel.

  • Publication number: 20070112373
    Abstract: A removable blood clot filter includes a number of locator members and anchor members disposed radially and extending angularly downward from a hub. The locator members include a number of linear portions having distinct axes configured to place a tip portion approximately parallel to the walls of a blood vessel when implanted and to apply sufficient force to the vessel walls to position the filter near the vessel centerline. The anchor members each include a hook configured to penetrate the vessel wall to prevent longitudinal movement due to blood flow. The hooks may have a cross section sized to allow for a larger radius of curvature under strain so that the filter can be removed without damaging the vessel wall.

  • Publication number: 20070083256
    Abstract: A covered self-expanding stent (20) can be restrained against axial movement with a pusher (40) within the lumen of the stent that carries a spiral of wire (48) that provides protrusions that are accommodated within a luminal covering layer (24) radially inside the stent body. The protrusions distribute the stress over the full length of the stent. The pusher can be removed from the stent lumen by “unscrewing” the spiral relative to the covering layer (24). When the stent expands, the pusher can be withdrawn proximally, out of the stent lumen, without any need for rotatory movement.

  • Patent number: 7175612
    Abstract: A suction limiting device with variable control for use in a surgical system includes a main vent body having a fluid carrying bore extending therethrough and a variable vent mechanism having a main vent opening in selective fluid communication with the fluid carrying bore so as to permit introduction of atmospheric air into the fluid carrying bore. The vent mechanism being adjustable so that the degree of airflow into the fluid carrying bore is variable between a fully open position to a fully closed position where atmospheric air is prevented from entering the fluid carrying bore. The suction limiting device also includes a valve disposed within the main vent body and positionable between an open position when negative pressure and a closed position when positive pressure exists in the main vent body.
