ABSTRACT:
A pad for use in combination with a bone marrow biopsy needle which is adapted to be slipped over the proximal end of the needle to provide an enlarged surface for distributing the pressure across the palm of the user. The pad includes a generally disc-shaped palm engaging surface along with a needle enveloping sleeve for releasable attachment to the biopsy needle. A bore is formed through the wall of the sleeve to provide communication between the interior of the sleeve and the atmosphere, thereby avoiding transfer of air between the pad element and the lumen of the needle when the pad element is mounted on the needle.
