| abstract |
A method for introducing an injectable medicament into a subarachnoid space of a patient includes advancing a subarachnoid needle into the subarachnoid space. The subarachnoid needle has an elongate passage with a sidewall, a proximal end and a distal end that has a closed point and at least two openings through the sidewall located at a distance from the closed point. The method includes establishing a fluid communication between the subarachnoid space and the passageway through the openings, then introducing the medicament into the subarachnoid space of the patient through the passageway. |
