  • Patent number: 8992442
    Abstract: The invention relates to a device for taking a liquid bone marrow sample (aspiration) and a solid bone sample (biopsy) in the same procedure, which can thus replace specialized needles for taking bone marrow and needles exclusively used for taking bone biopsies. The device for taking liquid bone marrow samples and a solid bone sample has a simple mechanism that uses two grooved clamps, it is easy to disassemble for sterilization and its handle is designed to perform the puncture easily. The needle of the device is hollow, and within it a guide is placed with two sections of different diameters. The guide makes it possible to open up the empty needle channel to allow the bone marrow liquid to flow and be extracted, and also to close the channel to be able to penetrate the tissue. The purpose of this invention is to combine the procedures of bone marrow aspiration and bone biopsy, thus reducing the patient's discomfort and the time needed for the procedure.

    Abstract: A biopsy device, comprising a flexible coaxial structure, comprising an obturator within a sheath, the obturator being adapted to be displaced with respect to the sheath along the coaxial axis by a force applied at a proximal end; a disruptor, at a distal end of the obturator, adapted to disrupt a tissue surface to free cells therefrom, having a first position covered within the sheath and a second position freely extending beyond the sheath; an element, having a fixed position on the obturator, and a close clearance with respect to an inner surface of the sheath, such that a retraction of the obturator within the sheath causes an associated change in pressure in a space between the obturator distal to the element and the sheath, to thereby draw fluid proximate to an end of the sheath within the sheath.

  • Patent number: 8882680
    Abstract: An improved flexible endoscopic instrument to precisely and efficiently obtains samples of flat polyps and multiple polyps from a patient by debriding one or more polyps and retrieving the debrided polyps without having to alternate between using a separate cutting tool and a separate sample retrieving tool and may be used with an endoscope. In one aspect, the cutting tool is coupled to a flexible torque coil or torque rope that is configured to transfer rotational energy from a powered actuator through the length of the endoscope onto the cutting tool.

  • Patent number: 8870788
    Abstract: Methods and device for extracting and collecting tissue, which can be used for example in tissue engineering and grafting applications, are disclosed. In one embodiment, a device can include an outer tube. A rotatable shaft can be disposed within the outer tube can have a tissue harvesting tip formed on its distal end, the tissue harvesting tip being effective to excise tissue upon rotation thereof. A tissue collection device can be included to receive and collected excised tissue, and the tissue collection device can indicate the amount of tissue collected therein. For example, the tissue collection device can include a straining element which collects excised tissue and an indicator by which to assess the amount of collected tissue. In some embodiments, the tissue collection device can translate to indicate the amount of collected tissue.

  • Patent number: 8864682
    Abstract: A biopsy device may include a needle, a cutter, and a handpiece. A vacuum pump may be provided in the handpiece for providing a vacuum to the needle and/or to the cutter. A motor may be provided in the handpiece to drive the vacuum pump and/or the cutter. A biopsy device may also include a valving mechanism within the handpiece for selectively communicating a vacuum and/or atmospheric air to the needle. A clutching mechanism may selectively provide communication between a motor and the cutter. Portions of a valving mechanism and a clutching mechanism may be integrally formed. A clutching and valving mechanism may be driven by a first motor; and a cutter and vacuum pump by a second motor. A biopsy device may include batteries for powering motors. A biopsy device may thus provide vacuum and power from within a handpiece, such that the biopsy device is tetherless.

  • Patent number: 8852120
    Abstract: Devices and methods for transplanting tissue for the purpose of regeneration, for treating a patient having injured myocardial tissue, and/or for improving cardiac function through cell regrowth. More specifically, the devices and methods obviate the need for cellular alteration. The devices comprise a hollow tube with a sharp distal end, a stylet that is disposed and movable within the hollow tube, and a stopping device that constrains movement of the stylet. The methods comprise removing intact tissue from a first region of a mammalian organ and implanting the tissue in a second region of the same organ.

  • Patent number: 8845546
    Abstract: A tissue sample holder for a biopsy device comprises an outer cup, a collection tray, and a flow restriction device. The outer cup defines a hollow interior. The collection tray separates the hollow interior into an upper chamber and a lower chamber while allowing fluid to pass between the two chambers through an opening in the collection tray. The flow restriction device selectively seals the opening thereby preventing fluid from passing from the lower chamber into the upper chamber. The flow restriction device may be operable to selectively seal the opening in response to a vacuum being induced within the upper chamber. The collection tray may have a shape (e.g., tapered, funnel-shaped, convex, etc.) selected to facilitate the flow of fluid toward the opening. The lower chamber may be coupled with an external fluid collection device. The lower chamber may define a larger volume than the upper chamber.
