The present invention provides improved devices for biopsy, aspiration, stem cell acquisition, and methods of using the same. The devices balance aspiration with concurrent infusion to manage changes in pressure at the site of biopsy. The present invention can be adapted for any biopsy, aspiration, or cell harvest procedure, including adipose tissue aspiration and bone marrow aspiration (BMA). In particular, the present invention limits patient pain, prevents blood contamination, and increases cell mobilization, such as improved stem cell yields with intraosseous (10) pharmacological mobilization of stem cells during a BMA procedure, and with improved stem cell yields using pharmacological mobilization of stem cells from fat. The pharmacological mobilization of cells allows the harvest of cells from a biopsy many fold larger than existing methods.

Aspiration device

An insertion apparatus for inserting an object into a body comprising a housing, a piercing structure with a lumen, wherein the piercing structure extends distally from the housing, a vacuum chamber that communicates with the lumen of the piercing structure, a plunger configured to fit within the vacuum chamber, a guidewire, and a pressure monitoring channel communicating with the lumen, wherein the insertion apparatus is configured to be operated with a single hand.
