Abstract
A needle system for providing fluidic and/or instrument access to an internal body structure. Exemplary embodiments may include non-linear needles having anatomically appropriate lengths and curvatures. Some exemplary embodiments may include a pivotable base, which may assist in stabilizing the needle system with respect to a body structure and/or may be reconfigurable into a safety guard position. Exemplary needle systems may include expandable conduits providing fluidic and/or instrument pathways into internal body structures.
Claims23
A needle system comprising:
- a housing having proximal and distal ends, and an axis extending between the proximal and distal ends;
- a tubular needle secured to the housing and having a length extending outward from the distal end of the housing between proximal and distal ends of the tubular needle, the tubular needle including a straight section, and a bent section, the bent section extending distally and non-linearly from the straight section, wherein a length of the bent section substantially corresponds to a depth of a biological structure beneath a tissue surface, wherein the biological structure is at least one of a vessel, vein, artery, joint, and organ;
- a base coupled to the housing such that the base is movable between a first position, in which the base extends distally from the housing and along the length of the tubular needle to cover the distal end of the tubular needle, and a second position, in which the base extends laterally away from the axis of the housing to uncover the distal end of the tubular needle.
A penetrating device system comprising:
- a housing;
- a needle device including a first section, a second section, a third section, a first bend interposing the first section and the second section, a second bend interposing the second section and the third section, and a depth indicator, wherein the first, second, and third sections are non-coplanar;
- a base coupled to the housing such that the base is movable between a first position and a second position, wherein the base has a base surface facing the needle device when the base is in the second position;
- and
- a latch configured to couple the base to the housing when the base is in the second position.
