A specimen bag configured for viewing the contents therein during a surgical procedure is provided. The specimen bag includes an open end and a closed end and defines a cavity. An appendage extends from the bag and defines a channel in communication with the cavity of the bag for receiving a surgical instrument.

A specimen retrieval device includes a bag having a closed bottom end portion and an open top end portion. The specimen retrieval device includes a cinch mechanism coupled to the open top end portion. The cinch mechanism includes a flexible band secured to the bag and a cinch coupled to the flexible band. The flexible band is movable relative to the cinch to reduce or enlarge a diameter of the open top end portion of the bag. The cinch is selectively engagable with the flexible band to fix the diameter of the open top end portion of the bag.

A method and system are disclosed for opening a workspace inside a lumen of a living creature are disclosed. Anchors may be affixed to opposite ends of the workspace. An extender may be distance anchors apart while they are affixed to the walls of the workspace. Distancing the anchors may unfold and/or stretch the lumen in the region of the workspace.

Systems and methods for preventing the seeding of cancerous cells during morcellation of a tissue specimen inside a patient's body and removal of the tissue specimen from inside the patient through a minimally-invasive body opening to outside the patient are provided. One system includes a cut-resistant tissue guard removably insertable into a containment bag. The tissue specimen is isolated and contained within the containment bag and the guard is configured to protect the containment bag and surrounding tissue from incidental contact with sharp instrumentation used during morcellation and extraction of the tissue specimen. The guard is adjustable for easy insertion and removal and configured to securely anchor to the body opening. Protection-focused and containment-based systems for tissue removal are provided that enable minimally invasive procedures to be performed safely and efficiently.

Components, systems and kits for capturing and removing tissue from mammalian bodies include a tissue container that may be introduced into a body cavity and within which a tissue specimen may be placed, cut and removed from the body cavity. Methods of using these components, systems and kits are also described.

A method and a device for secured retrieval of tissue from inside a patient body and a kit comprising the device. the device comprises a tube housing a movable cutter. The cutter controllably extends from the tube while allowing continued fluid communication. The device comprises a retractable enclosure with a supporting frame linked to an impermeable membrane comprising an opening. Amplitude of the supporting frame is controlled. The opening in the impermeable membrane is unseal when enclosure is expanded and, when the tissue is positioned within the enclosure, the opening is sealably closed in the impermeable membrane. The moveable cutter morcellates the tissue into tissue specimens when the opening in the impermeable membrane is sealably closed while amplitude of the supporting frame is reduced to compress the tissue specimens and the tissue specimens are able to transit in the fluid communication channel through a discharging aperture after morcellation.

A retrieval catheter and methods of use are described for removing a heart valve therapy such as a leaflet clip or artificial leaflet cord. The retrieval catheter can include a cutting element and a basket, piercing element, clamping mechanism, or similar grasping device. The method includes delivering a catheter to the region of the heart valve therapy and then manipulating the catheter and associated instruments to cut tissue as necessary and then remove the heart valve therapy and withdraw the catheter.

A surgical apparatus for positioning within a tissue incision to access an underlying body cavity and remove a tissue specimen therefrom includes a wound retractor having a specimen bag attached thereto. The wound retractor includes a proximal ring, a distal ring, and a film extending therebetween defining a longitudinal passage therethrough. The specimen bag is attached to the distal ring of the wound retractor and permits placement of a tissue specimen to be removed from the body therein.

A minimally invasive endovascular device for treating a blocked or obstructed biological lumen, such as a blood vessel fully or partially obstructed by deposits of biological matters in or non-biological matters. Certain embodiments of the present invention comprise two capture members that are configured to be placed on either side of the obstruction and enclose around the obstruction for removal. Embodiments of the present invention also provide methods for implementing an endovascular device according to aspects of the present invention.

A method of viewing the contents of a specimen bag includes, placing tissue within a cavity of the specimen bag through an open end of the specimen bag, engaging a stretchable portion of the specimen bag with a scope to stretch the stretchable portion of the specimen bag, and operating the scope to view the contents of the specimen bag.
