Bone marrow aspirator
First Claim
1. A bone marrow aspiration device, comprising:
- an elongate handle having proximal and distal surface extending between opposed first and second ends, the first and second ends defining a central axis extending therebetween, the handle having a shape adapted to facilitate grasping thereof;
an elongate penetrating element having a proximal portion coupled to the handle and having a proximal end with an inlet port formed therein and positioned at a location on the handle between the opposed first and second ends of the handle, a distal portion having a smooth outer surface and a solid, distal piercing tip, a substantially cylindrical sidewall defining an inner lumen extending from the inlet port to a position proximal to the distal piercing tip, and at least one opening formed in the sidewall and in communication with the inner lumen, the at least one opening being positioned proximal to the distal piercing tip;
wherein the proximal portion of the elongate penetrating element is offset with respect to a longitudinal axis of the distal portion of the elongate penetrating element such that the handle of the device can be grasped and manipulated to position the distal portion of the elongate penetrating element while simultaneously allowing access to the inlet port in the proximal portion of the elongate penetrating element.

Abstract
A bone marrow aspiration device is provided having a handle adapted to facilitate grasping thereof, and an elongate penetrating element coupled to the handle and having a proximal inlet port and a distal piercing tip for penetrating into tissue and bone. The device is particularly effective in that the configuration of the handle and the elongate penetrating element allows a person to grasp and manipulate the handle while accessing the inlet port to aspirate fluid therethrough. The device is also effective to facilitate penetrating of the device into bone due to the configuration of the distal penetrating tip. A person having ordinary skill in the art will appreciate that, while the device is described for use as a bone marrow aspiration device, the device can be used to withdraw or inject fluid.

19. A bone marrow aspirator device, comprising:
-
a handle having proximal and distal surfaces extending in a substantially horizontal plane between opposed ends of the handle; and
an elongate bone penetrating member positioned a distance apart from at least one of the opposed ends of the handle and including a proximal portion having a proximal inlet port and a distal portion having a distal bone penetrating tip, the proximal and distal portions extending in a direction substantially transverse to the horizontal plane of the handle, and the proximal portion of the bone penetrating member having an axis offset from, but substantially parallel to an axis of the distal portion of the bone penetrating member, an intermediate portion disposed between the proximal and distal portions and oriented to extend substantially parallel to the handle, an inner lumen extending between the proximal port and the distal portion of the elongate bone penetrating member, the inner lumen terminating proximal to the distal bone penetrating tip, and at least one opening formed in the distal portion of the elongate penetrating element proximal to the distal bone penetrating tip, the at least one opening being in communication with the inner lumen. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A bone marrow aspiration device, comprising:
-
an elongate handle having at least one side surface extending between opposed ends that define a central axis extending therebetween; and
a bone penetrating member coupled to the handle at a location offset from a substantial midpoint of the handle, the midpoint being located between the opposed ends, the bone penetrating member including a proximal portion positioned with the handle and having an inlet port located on a side surface of the handle, a distal portion extending from a side surface of the handle at a location that is offset along the central axis of the handle from the location of the inlet port, the distal portion including a distal penetrating tip, and an inner lumen extending from the inlet of the proximal portion through the bone penetrating member to an opening located in the distal portion and positioned proximal to the distal penetrating tip. - View Dependent Claims (32, 33, 34, 35)
