Abstract: A biopsy needle for collecting a tissue specimen includes an outer cannula and an inner tube received within the outer cannula. A snare coil is attached between the inner tube and the outer cannula and is configured to wind down when the inner tube rotates in a first direction relative to the outer cannula. The outer cannula is fixedly coupled to a needle holder that is coupled to and moves with a movable base that is axially movable within the handle housing. An inner driven structure (curvilinear part) is configured to selectively engage the movable base and travel therewith in a first stage of operation and in a second stage of operation in which the inner driven structure is disengaged from the movable base, the inner driven structure is driven along the movable base which is held in a stationary position.

Abstract: A biopsy needle for collecting a tissue specimen includes an outer cannula that is at least partially received within a handle housing and an inner tube received within the outer cannula and configured to receive a stylet. A snare coil is attached between the inner tube and the outer cannula and is configured to wind down when the inner tube rotates in a first direction relative to the outer cannula and uncoil when the inner tube rotates in a second direction relative to the outer cannula. The outer cannula is fixedly coupled to a needle holder that is coupled to and moves with a movable base that is axially movable within the handle housing. An inner driven structure (curvilinear part) is configured to selectively engage the movable base and travel therewith in a first stage of operation and in a second stage of operation in which the inner driven structure is disengaged from the movable base, the inner driven structure is driven along the movable base which is held in a stationary position.

A snare coil is attached between the inner tube and the outer cannula and a movable base is disposed within the handle housing. The outer cannula is fixedly coupled to the base and the movable base is axially movable within the handle housing. An inner driven structure that is coupled to the inner tube is configured to travel axially across an upper surface of the movable base. The coupling between the inner driven structure and the inner tube is such that the axial driving of the inner driven structure imparts rotation to the inner tube relative to the outer cannula.

Abstract: A cuffed-catheter removal device includes a handle and a shaft extending from the handle. The shaft extends from the handle to a distal end of the cuffed-catheter removal device. At the distal end of the cuffed-catheter removal device the shaft includes a C-shaped shaft member with a concave recess shaped and dimensioned for attachment and tracking along an exposed catheter shaft.

Abstract: A guidewire steering device includes a gripping member and a compression member. The gripping member includes opposed first and second gripping surfaces positioned for selective engagement of a guidewire positioned therebetween. The first gripping surface includes a first end and a second end and the second gripping surface includes a first end and a second end. The first and second gripping surfaces being oriented to permit selective gripping of a guidewire positioned therebetween. The second end of the first gripping surface and the second end of the second gripping surface are spaced apart in a manner defining a lateral access slot through which a guidewire may be passed for positioning between the first and second gripping surfaces.
