A61B 1708

606213

A device for expansion within a blood vessel having a wall defining a lumen in the body. The device comprises an elongated tubular member having proximal and distal extremities and having a longitudinal axis. An expansile member is carried by the distal extremity of the elongated tubular member and is movable between contracted and expanded configurations. A deformable membrane having proximal and distal outer surfaces at least partially covers the expansile member in the expanded configuration. The proximal and distal outer surfaces have substantially different configurations when the expansile member is in the expanded configuration. Deployment tool is carried by the proximal extremity of the elongated tubular member and is coupled to the expansile member for moving the expansile member between the contracted and expanded configurations. A handle assembly is carried by the proximal extremity of the elongated tubular member and coupled to said deployment tools.

A medical fluid suctioning device for selectively applying varied levels of suction pressure at a device-tissue interface includes a direct “trumpet”-type control mechanism in conjunction with a “venturi”-type control. A valve manifold is adapted to couple a vent pathway and a suction pathway simultaneously to the vacuum conduit adapted for connection to a vacuum source. The amount of resistance to flow due to vacuum pressure is adjusted simultaneously in both the vent pathway and the suction pathway in order to achieve controlled, selected levels of suction. Similarly shaped valve apertures are provided in inverse and reciprocal orientation along an axis of motion of a valve manifold. The apertures translate across ports to the suction and venting pathways simultaneously to vary applied suction to those pathways inversely. The shaped valve apertures preferably have diminished elliptical shapes having an elongate axis with an increasing cross-sectional area going from a transverse short axis to a transverse wide axis along the axis of motion of the valve manifold.

A device for expansion within a blood vessel having a wall defining a lumen in the body. A first elongate tubular member has proximal and distal extremities and has a longitudinal axis. An expansile member is carried by the distal extremity of the first elongate tubular member is and movable between contracted and expanded positions. The expansile member has a predetermined configuration in the expanded position. A deformable membrane covers the expansile member, and is sized so as to be capable of overlying and underlying the expansile member in the expanded position. A deployment mechanism is carried by the proximal extremity of the first elongate tubular member and is adapted to be operated by the human hand for controlling movement of the expansile member between the contracted and expanded positions. A deployment mechanism includes a push-pull wire with proximal and distal extremities and extends through the first elongate tubular member and is coupled to the expansile member.

A device for introducing and polymerizing polymeric biomaterials in the human body. The device has a first elongate tubular member having proximal and distal extremities and a longitudinal axis. An expansile member is carried by the distal extremity of the first elongate tubular member and is movable between contracted and expanded positions. The expansile member has a predetermined configuration in the expanded position. A deformable membrane covers the expansile member and is sized so as to be capable of overlying and underlying the expansile member in the expanded position. A second elongate tubular member has proximal and distal extremities, a longitudinal axis and a first lumen extending from the proximal to the distal extremity of the second elongate tubular member. The distal extremity of said second elongate tubular member terminates proximal to the distal extremity of said first elongate tubular member and adjacent to said expansile member. The first elongate tubular member is carried by said second elongate tubular member.

The inventive ablation element comprises an elongated cannula having a proximal end and a distal end. The cannula defines an internal lumen within the cannula and a cannula axis. A plurality of conductors contained within the lumen, each of the conductors has a proximal end proximate the proximal end of the cannula, and a distal end proximate the distal end of the cannula. A plurality of ablation stylets each has a proximal end and a distal end, and each coupled at the respective proximal end of the stylet to the distal end of a respective conductor, the stylets comprise a deflectable material, the conductors together with their respective stylets being mounted for axial movement. A trocar point defined proximate the distal end of the cannula.

A sealant applicator suitable for dispensing a coagulable sealant, for example a two-component fibrin sealant mixed in the applicator, employs impulse clearing to remove residual coagulated or coagulating material from the dispensing pathway and mixing chamber, if present. Impulses may be generated by manual application of a clearing member such as a plunger which can enter into the dispensing pathway to engage, dislodge and discharge residuals or can generate a gas impulse to impact the residuals to similar effect. A clearing valve having a clearing port can be operated by movement of the clearing member to provide access to the dispensing pathway.

The inventive method for ablating a tissue mass associated with a human or animal patient being treated comprises positioning an ablating electrode in a tissue mass to be ablated. A plurality of return electrodes are positioned on the patient. Electrical energy is applied between the return electrodes and the ablating electrode. The temperature of the return electrodes is measured to generate a temperature measurement signal which is used to control ablation current through the return electrodes.
