Abstract: A drainage device and method of draining a biological fluid from the body of a patient is disclosed. The drainage device includes a drainage tube, a pressure relief assembly, a cleaner assembly, and a housing. The drainage tube includes an array of apertures in it through which biological fluid from the patient can flow for collection by a collection canister. The cleaner assembly includes a squeegee unit configured to be pulled in a proximal direction from a distally located position in the drainage tube to scrape any biological material adhering on the inner surface of the drainage tube and carry it to the collection canister. The pressure relief assembly serves to equalize the pressure in the drainage tube as it is being cleaned. The squeegee unit also acts as a pressure relief valve to equalize the pressure within the drainage tube when the squeegee unit is retracted back to its distally located position.

Abstract: Systems and methods for facilitating the removal of a tissue specimen from a patient are disclosed. The systems include a bag or pouch, a tissue cutter device, a support and a stabilizer. The tissue cutter device includes a passer, a wire, and a handle. The support is an elongated member. The passer is an elongated member configured to be coupled to the support and introduced as a temporary unit into the mouth of the bag or pouch in the patient's body holding the tissue specimen. The wire is attached to the passer. The temporary unit is configured to pass around the tissue specimen and out of the opening in the bag or pouch to carry the wire through that path so that a distal portion of the wire and a proximal portion of the wire are outside the patient's body. Those portions of the wire can be pulled to cut into the tissue specimen. The stabilizer holds the tissue specimen as the wire cuts into it.

Abstract: A system and method for removing a tissue specimen or organ from the body of patient is disclosed. The system includes a bag and an excising instrument. The tissue specimen or organ is located in the bag, which is located in the patient's body. The instrument comprises a guide and a cutter. The guide is configured for introduction into the bag. The cutter is rotatable within the guide and includes a central passageway and an annular cutting blade. The cutting blade is brought into engagement with a peripherally located portion of the tissue specimen and rotated to produce a tangentially cut peripheral portion while a pulling force is applied to the tissue specimen through the central passageway. The pulling force rotates the tissue specimen within the bag to effect the production of the tangentially cut peripheral portion and to move the tangentially cut peripheral portion out of the patient's body. Gas pressure may be applied to inflate the bag to facilitate placement of the excising instrument.

Abstract: Entrapment and collection systems and method of entrapping and collecting biologic material produced on a patient are disclosed. The systems include a collection bag which formed of a flexible sheet material having a hollow interior, a first mouth and a second mouth. The first mouth is openable to enable the biological structure to be disposed in the hollow interior and to enable a removal instrument, e.g., a morcellator, to be introduced therethrough to engage the biologic structure to effect a procedure on it. The second mouth enables a viewing instrument to be extended through it for visualizing the procedure and is closeable by a drawstring to entrap biologic material produced by the procedure after the removal instrument and viewing instrument have been removed, whereupon the collection bag may be withdrawn from the body of the patient.
