  • Patent number: 10039569
    Abstract: Lead tip removal is accomplished by first stabilizing an area around the lead tip attachment site in the heart wall. A balloon located at the tip of the lead when inflated expands substantially perpendicular to the lead, stabilizing the area around the lead tip. Upon further inflation, the balloon expands substantially parallel with the lead, causing the lead tip to pull away from the heart wall. In another embodiment, a sheath is inserted over the lead and advanced to the heart wall. A passive or active stabilization device is attached to the sheath tip to stabilize the area around the lead tip. In another embodiment, a balloon is located at the tip of the sheath that, when inflated, expands substantially perpendicular to the lead, stabilizing the area around the lead tip. The lead tip is removed with less force due to the stabilization provided to the lead tip area.

  • Patent number: 9974642
    Abstract: An expandable vascular sheath utilizes a set of expandable members such as shape memory alloy wires for expanding its distal end. The wires are slidable along a portion of the sheath's elongate shaft. In certain embodiments, the distal end of the shaft is manufactured with a more pliable and elastic polymer relative to more proximal portions of the elongate shaft, so that as the wires advance into distal portions of the shaft, they expand, causing the distal end opening of the shaft to expand. A method for retrieving a foreign object from a vasculature utilizes a retrieval tool that can be advanced through the expandable vascular sheath.

  • Patent number: 9034007
    Abstract: A distal embolic protection device for dedicated use in cerebral arterial blood vessels is described. The distal embolic protection device comprises a variable-thickness micro-guidewire and a collapsible filtering device mounted on the microguidewire over two mobile attachment points so that in its collapsed configuration, the thickness of the microguidewire and the filtering device at this region is less than or equal to 0.017 inch (0.432 mm) in thickness to be able to pass through existing conventional microcatheters. The mobile attachment points allow for rotatory and longitudinal mobility of the microguidewire while the filtering device is stable thereby decreasing the risk of trauma to the fragile cerebral arterial blood vessels. Preferably, the filtering device comprises an expansion assembly, e.g., a plurality of struts attached to a filter membrane that are in a folded position which self expand to the desired dimensions within the cerebral blood vessels.

  • Patent number: 9017340
    Abstract: A system for retrieving a specimen includes a collapsible bag having a first mating member and a retrieval device having a second mating member. The second mating member cooperates with the first mating member for coupling the collapsible bag with the retrieval device. A rotation mechanism is disposed in the retrieval device. Actuation of the rotation device collapses an excess portion of the collapsible bag.

  • Publication number: 20150105790
    Abstract: A surgical tissue retrieval instrument has a collapsible pouch at the distal end of an elongated pusher rod that is introduced into a patient through a cannula. The instrument includes a two-jaw fork that forms a loop when in an unconstrained configuration and that supports the pouch. Deployment and operation of the fork and the pouch are controlled by a securing mechanism. The two jaws and the securing mechanism are slid in a hem surrounding the opening of the pouch when the device is assembled.

  • Patent number: 8986321
    Abstract: A tissue retrieval device includes a tubular member, an expandable member, and a tissue retrieval bag. The introducer tube is sized to be inserted into a patient through a trocar. The bag may be selectively opened by the expandable member within the patient. The bag may receive a tissue specimen and be withdrawn from the patient. The bag may be manipulated for packing within the tubular member in a variety of ways. Manipulation of the bag may include folding the bag about axes that are perpendicular to or parallel to the tubular member; rolling the bag about axes that are perpendicular to or parallel to the tubular member; or wrapping the bag about the expandable member, wrapping the bag about a rod, or twisting the bag at a position distal to the expandable member. The tubular member may comprise an environmentally responsive capsule.

  • Patent number: 8968329
    Abstract: A surgical retrieval apparatus includes a handle including an elongated sleeve extending therefrom that, together cooperate to define a lumen therethrough. A shaft having an end effector assembly disposed at a distal end thereof and a plunger disposed at a proximal end thereof is selectively translatable between a first position and a second position, wherein the end effector assembly extends from the sleeve. An articulation mechanism is configured to articulate the end effector assembly relative to the shaft. A specimen retrieval bag is coupled to the end effector assembly and is deployable to an extended position upon movement of the end effector assembly to the second position.

  • Patent number: 8956370
    Abstract: A tissue retrieval system can contain and withdraw excised tissue specimens from within a body cavity. The tissue retrieval system can include a tissue retrieval bag, a foldable actuator, and an introducer. The foldable actuator can be foldable between an insertion configuration for placement through an access device without the aid of a grasper or applicator, and a deployed configuration for supporting the tissue retrieval bag in an open state. The actuator can have a foldable handle to facilitate withdrawal from the body cavity. After insertion of the tissue specimens into the retrieval bag, the retrieval bag is then cinched closed to prevent spillage of its contents and to prevent contamination of the body cavity and body cavity wall during withdrawal of the retrieval bag from within the body cavity.

  • Publication number: 20150045808
    Abstract: A surgical retrieval apparatus for receipt of multiple tissue specimens includes a collection bag, a support ring, and a flip ring. The collection bag includes first and second packets each having an outer portion and an inner portion. The first and second packets define first and second adjacent chambers, respectively, that are each configured for receipt of a tissue specimen therein. The first and second packets are coupled to both the support ring and the flip ring. The flip ring is pivotably coupled to the support ring and is rotatable relative to the support ring between a first position, wherein the first chamber is accessible for depositing a tissue specimen therein and a second position, wherein the second chamber is accessible for depositing a tissue specimen therein.
