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.
Claims22
An access device comprising:
- a rigid non-linear guide configured to be inserted into a body structure;
- and
- a conduit having a first configuration for insertion into the body structure in which at least a portion of a length of the conduit is tightly collapsed and affixed to an exterior of at least a portion of a distal section of the guide, and a second configuration in which inner and outermost dimensions along the entire length of the conduit are expanded by the application of internal pressure to provide an expanded internal passage,
- wherein the guide is configured to be detachable and removable from the conduit after the conduit is in the expanded second configuration.

An access device comprising:
- a rigid non-linear penetrating guide;
- and
- a conduit, defining an internal passage, having a first configuration for insertion into a body structure in which at least a distal portion of a length of the conduit is tightly collapsed and affixed to an exterior of at least a portion of a distal section of the penetrating guide, and a second configuration in which the internal passage and outermost dimension along the entire length of the conduit are expanded from the first configuration by the application of internal pressure,
- wherein the penetrating guide is configured to be detachable and removable from the conduit after the conduit is in the expanded second configuration.
