Abstract

Apparatus for delivering a quantity of fluid to bone marrow of a bone or providing access to remove fluids from a target site is provided. The apparatus may include a driver, a plunger operating and cartridge assembly mechanism, a cartridge assembly having a fluid reservoir and a bone penetrating needle.

Claims

1. A bone penetrating needle operable to deliver a quantity of fluid to bone marrow of a bone comprising:

a first end having a closed tip;

at least one cutting edge formed on the closed tip for use in penetrating the bone and bone marrow;

a second end operable to receive a quantity of fluid from a fluid reservoir;

the second end disposed in a hub having a threaded connection that is operable to be engaged with a fluid reservoir or connector to communicate fluids to bone marrow;

a longitudinal bore extending from the second end to a location proximate the closed tip;

at least one side port located proximate the closed tip;

the at least one side port communicating with the longitudinal bore proximate the closed tip;

the at least one side port disposed at an acute angle relative to the longitudinal bore to minimize obstruction of the at least one side port and the longitudinal bore by bony fragments during insertion of the bone penetrating needle into the bone and associated bone marrow; and

a non-threaded outer surface of the needle extends from the first end to the hub;

where the hub includes a proximal end, a distal end, and a flange having a maximum transverse dimension disposed at the distal end of the hub, the flange coupled in fixed relation to the bone-penetrating needle, the flange configured to contact skin overlying a bone if the bone-penetrating needle is driven into the bone.

2. The bone penetrating needle of claim 1 further comprising multiple side ports disposed at acute angles relative to the longitudinal bore and communicating with the longitudinal bore.
