  • Patent number: 10849604
    Abstract: A method of removing an appendix (9) includes the steps of accessing the abdomen of a patient, insufflating the abdominal cavity, and sealing and cutting the appendicular artery and vein. A sheath is introduced into the abdominal cavity and placed over the appendix, while the appendix is still attached to the colon. The sheath is secured the sheath in place over the appendix using a securing device to secure the sheath with respect to the proximal end of the appendix, and then the proximal end of the appendix is ligated. The appendix is dissected from the colon, and the sheath containing the appendix is removed from the abdomen of the patient. The procedure can be a NOTES procedure, using a natural orifice, or laparoscopic using one or more incisions created in the abdomen. The ligation and dissection can be performed within the abdomen, or after the appendix is pulled through one of the incisions, such that the ligation and/or dissection is carried out outside the abdomen.

  • 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.

    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: 9974554
    Abstract: Devices and methods for removal of calculus (including for example, kidney stones) are disclosed. In an embodiment, a device for removal of kidney stones includes a substantially sealable pouch that can be inserted into the kidney for capturing a kidney stone. The pouch is also designed to permit fragmentation of the kidney stone inside the pouch, while preventing kidney stone fragments from escaping from the pouch. As a result, the likelihood of dispersing stone fragments during fragmentation of a large stone is greatly lessened.

  • Patent number: 9943322
    Abstract: A device may include a distal assembly including a first plurality of legs, a second plurality of legs, and a distal tip, and further include a first driver and a second driver, a proximal end of at least one leg of the first plurality of legs may be coupled to the first driver, and a proximal end of at least one leg of the second plurality of legs may be coupled to the second driver. The medical device may include a first longitudinally extending hollow member movably positioned along the first driver and a second longitudinally extending hollow member movably positioned along the second driver. Movement of the first longitudinally extending hollow member relative to the first driver may converge legs of the first plurality of legs, and movement of the second longitudinally extending hollow member relative to the second driver may converge legs of the second plurality of legs.

  • Patent number: 9901329
    Abstract: A collapsible and expandable receptacle that can be inserted into a patient's cavity through a laparoscopic port (sleeve) is disclosed herein. The receptacle is configured so that when it enters the cavity it can be expanded or opened into a shape of a bowl or cone. A targeted tissue specimen can then be placed inside the expanded receptacle, and the surgeon has the room and visibility to cut the tissue with a power morcellator and avoid severing the bag or spreading unwanted particulate tissue to other areas inside the patient. Once the specimen has been cut and removed, the empty receptacle can be collapsed and removed out the same tissue removing sleeve.

  • Patent number: 9877740
    Abstract: A morcellator shield and bag assembly including a shield having a cavity and a bag coupled to the shield. The bag is moveable between a contracted position, in which at least a portion of the bag is positioned within the cavity, and an expanded position. The bag has an opening that is in fluid communication with the cavity when the bag is in the expanded position. A method for using the assembly along with a morcellator to remove tissue from a body cavity. The method includes inserting at least a portion of the assembly into a body cavity, moving the bag to the expanded position, placing tissue in the bag, pulling the bag through an opening in a patient, inserting the morcellator into the assembly, and morcellating the tissue with the morcellator. The assembly is designed to contain the tissue being morcellated and prevent the morcellator from contacting the bag.

  • Patent number: 9833250
    Abstract: An apparatus for treating hemorrhoids including a first member having a proximal portion, a distal portion and a window formed therein to receive tissue. A third member is operably connected to the second member and movable between a first position and a second position, the third member having a clamping surface movable to the second position to provide a clamping force on tissue received through the window. Movement of the second member in a distal direction moves the third member in the distal direction toward the second position, the third member movable in a distal direction until such movement is limited due to contact and compression of tissue within the window, the second member continuing movement in the distal direction after movement of the third member in the distal direction has been limited.

  • Patent number: 9763684
    Abstract: An apparatus includes a transmission member having a proximal end portion and a distal end portion. The transmission member is configured to be inserted into a bodily lumen, and is configured to transfer ultrasonic energy from the proximal end portion to the distal end portion. The transmission member defines a lumen along a longitudinal center line of the transmission member. The distal end portion of the transmission member includes a concave engagement surface and a distal end surface. The distal end surface defines a plane that intersects the longitudinal center line of the transmission member at an angle of between about 75 degrees and about 105 degrees. The engagement surface is configured to engage a target tissue within the bodily lumen to limit movement of the target tissue along the longitudinal center line. The engagement surface defines an opening in fluid communication with the lumen.
