Device and method for rapid aspiration and collection of body tissue from within an enclosed body space

Device and method for rapid extraction of body tissue from an enclosed body cavity. Hollow entry cannula with optional core element provides entry into body tissue space such as bone marrow. Aspiration cannula is inserted through the hollow entry cannula into the body tissue and is manipulated to advance directionally through the body cavity. Optional stylet within the aspiration cannula aids in advancing the aspiration cannula through the body tissue and is removed to facilitate extraction of the body tissue through the aspiration cannula. Inlet openings near distal tip of the aspiration cannula allow tissue aspiration, with negative pressure source at the proximal end of the aspiration cannula providing controlled negative pressure. The aspiration cannula may be withdrawn and its path adjusted for multiple entries through a same entry point, following different paths through the body tissue space for subsequent aspiration of more tissue.

Bone marrow harvesting and storage

Methods of extracting bone and/or cellular material from a patient for possible use in a later surgical procedure, which involves that patient or even a different patient, are provided. An embodiment of the method generally comprises extracting bone and/or cellular material from a patient undergoing a routine surgical procedure, saving the material, and then sending it to a storage, separation, and processing facility (e.g., a biobank) for use in a later surgical procedure involving that patient, or a different patient. The material may be cancellous bone, cortical bone chips, or bone marrow. The extracted bone and/or cellular material can be processed at the biobank and used in a multitude of different medical procedures (e.g., as an allograft infused with stem cells for use in a fusion procedure).

INTERMITTENT SUCTION REGULATION DEVICE AND METHOD

Methods and devices for regulating suction pressure are disclosed. The suction regulator device may include a housing including three ports and a valve engaging the ports. The method includes connecting a vacuum source to the first port, connecting a suction powered device to the third port, and oscillating the valve between maintaining a closed configuration for a predetermined time period and maintaining an open configuration for a second predetermined time period. In the closed configuration the valve places the third port in fluid communication with the second port exposing to ambient/atmospheric pressure and in the open configuration the valve places the third port in fluid communication with the first port.

Bone fragment collector and processor

A device for collecting and processing bone fragments comprises a housing and a filter element disposed in the housing. The filter element at least partially defines a collection chamber for the collection of a composition comprising bone fragments. An inlet cap is releasably coupled to either the housing or to the filter element and configured to receive the composition. The inlet cap includes a body, an inlet port extending from the body and configured to be coupled to a surgical tool, and a spout extending from the body opposite the inlet port. The spout includes an injection port extending into the collection chamber of the filter element. A outlet cap is releasably coupled to the housing and is configured to be coupled to a vacuum source.
