    摘要: An anchoring member which comprises a support structure and at least one anchor secured to the anchoring member is disclosed. An anchor deflection member is disposed generally externally to and at least partially surrounding and extending along the perimeter of the anchoring member. The anchor deflection member supports the anchoring member for sliding longitudinal movement in directions which result in advancement and retraction of a point on the anchor. The anchor deflection member defines a guide surface positioned on the inside of the anchor deflection member. The guide surface extends longitudinally, and it is configured and dimensioned to slidingly guide the cylindrical anchoring member. A deflection lip is positioned relatively inwardly with respect to the guide surface. The deflection lip is positioned to outwardly deflect the point of the anchor as the anchor is advanced from a position removed from the deflection lip toward the deflection lip into contact with the deflection lip and beyond the deflection lip.

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 deflection surface positioned between the trocar point and the proximal end of the cannula, the deflection surface being configured and positioned to deflect, in response to axial movement of the stylets in a direction from the proximate end of the cannula to the distal end of the cannula, at least some of the stylets laterally with respect to the cannula axis in different directions along substantially straight paths, the paths defining an ablation volume.

    摘要: A fuel-air premixer for a combustor of a gas turbine engine includes a central passage disposed along an axis and operable to communicate a first airflow and an outer annular passage about the axis operable to communicate a second airflow. The fuel-air premixer further includes an inner annular passage about the axis and between the central passage and the outer annular passage for communicating fuel flow. The inner annular passage including an inner exit angled for directing fuel flow toward the axis into a mixer passage downstream of the outer and inner exits for mixing the fuel flow with the first and second airflows.
