  • Publication number: 20040210244
    Abstract: An anastomosis device is a one piece device for connecting a graft vessel to a target vessel without the use of conventional sutures. The anastomosis device includes an expandable tube configured to have a graft vessel secured to the tube. The device has an expandable linkage positioned at one end of the device and expansion of this linkage causes a first radially extending flange to fold outward. This first flange abuts an interior wall of a target vessel and a second flange is formed which abuts an exterior wall of the target vessel trapping the target vessel between the two flanges and secures the end of the graft vessel into an opening in the wall of the target vessel. The device greatly increases the speed with which anastomosis can be performed over known suturing methods and allows anastomosis to be performed in tight spaces.

  • Publication number: 20040167550
    Abstract: An integrated anastomosis tool both creates an opening in a side wall of a target blood vessel and performs an anastomosis procedure to connect a graft vessel to a side of the target blood vessel with a single integrated tool. The integrated anastomosis tool includes a cutting device, a graft vessel attachment device, an introducer, and a tool body. In each of the embodiments of the anastomosis tool, the advancement paths of a cutting device and a graft vessel attachment device cross, intersect, or align so that both the cutting device and the graft vessel attachment device can be operated by a single tool at the same intended anastomosis site in a sequential manner. The anastomosis procedure can be performed on a pressurized vessel since there is no need to interchange tools during the procedure.

  • Publication number: 20040148035
    Abstract: Disclosed is an apparatus for deploying a bronchial isolation device in a bronchial passageway in a lung of a patient. In one embodiment, the apparatus includes an outer shaft having a distal end. A housing is coupled to the distal end of the outer shaft and configured to receive the bronchial device. An inner shaft is slidably disposed within the outer shaft. A handle is adapted to move the outer shaft relative to both the inner shaft and the handle while the inner shaft remains fixed relative to the handle so as to eject the bronchial isolation device from the housing.

  • Publication number: 20040098011
    Abstract: A tissue punch for creating a hole in the wall of a target blood vessel for receiving an anastomosis device includes a piercing element for penetrating the tissue and a cutting element for cutting a plug of tissue around the pierced hole. The tissue punch includes a trocar for inserting the piercing element. After punching is complete, the piercing element is removed from the trocar through a side wall of the trocar so that a medical device can be deployed through the trocar lumen. The tissue punch may also include a tissue trap for trapping the plug of tissue.

  • Publication number: 20040089306
    Abstract: Disclosed are methods and devices for removing bronchial isolation devices from a lung. According to one method, a flow control device is removed from a bronchial passageway of a patient. A removal device having an elongate shaft and a distal engaging element is provided. The removal device is inserted through the bronchial isolation device such that the distal engaging element is positioned within or distally of the bronchial isolation device in the bronchial passageway. The engaging element is then transitioned to have a radial size that is larger than the radial size of at least a portion of the bronchial isolation device. The bronchial isolation device is engaged with the distal engaging element to urge the bronchial isolation device in the proximal direction, thereby removing the bronchial isolation device out of the bronchial passageway. The bronchial isolation device can also be equipped with a handle that will collapse the bronchial isolation device when force is applied to the handle.

  • Publication number: 20040055606
    Abstract: Disclosed is a flow control device for a bronchial passageway. The device can includes a valve member that regulates fluid flow through the flow control device, a frame coupled to the valve member, and a membrane attached to the frame. At least a portion of the flow control device forms a seal with the interior wall of the bronchial passageway when the flow control device is implanted in the bronchial passageway. The membrane forms a fluid pathway from the seal into the valve member to direct fluid flowing through the bronchial passageway into the valve member.

  • Publication number: 20040039250
    Abstract: Disclosed are method and devices for deploying a guidewire in a lung of a patient. The method comprises removably coupling a distal end of the guidewire to a distal end of a delivery device having an elongated shaft and a lumen extending therethrough. The distal end of the delivery device is delivered through the patient's trachea into a bronchial passageway of the lung so that the distal end of the guidewire is disposed in the bronchial passageway. The delivery device is then removed from the a bronchial passageway while the distal end of the guidewire remains in the bronchial passageway.

  • Publication number: 20030120293
    Abstract: The anastomosis device according to the present invention is a one piece device for connecting a graft vessel to a target vessel without the use of conventional sutures. The anastomosis device includes a frame for receiving and holding the end of a graft vessel in an everted position and first and second spreading members configured to be inserted into an opening in the target vessel. The first and second spreading members are arranged substantially in a plane for insertion into an opening in a target vessel, and are moved away from one another to capture the edges of the opening in the target vessel securing the graft vessel to the target vessel. One version of the anastomosis device includes a plurality of linkages arranged in two rows for grasping opposite sides of an opening in the target vessel. A portion of the linkages fold outward to trap vessel walls on opposite sides of the opening in the target vessel.

  • Publication number: 20030109893
    Abstract: A medical device which can be implanted at a target site in a living body. The device includes an inner flange formed by radial expansion of the device and an outer flange formed by axial compression of the device. The device can include an implant portion and a discard portion which separate from each other during formation of the outer flange. The separation can occur by fracturing a frangible linkage or by mechanically separating a portion of the outer flange from a deployment tool. The device can be a one piece anastomosis device for connecting a graft vessel to a target vessel without the use of conventional sutures. The inner and outer flanges capture the edges of an opening in a target vessel and secure the graft vessel to the opening in the target vessel. The device greatly increases the speed with which anastomosis can be performed over known suturing methods.

  • Publication number: 20030028205
    Abstract: An anastomosis system and method uses an anvil to control and support a tissue site during an anastomosis procedure. The anvil is particularly useful for supporting a wall of a coronary artery during attachment of a graft vessel to the coronary artery because the wall of the coronary artery is very thin, difficult to grasp, and susceptible to tearing. In one method, the anvil is inserted into a pressurized or unpressurized target vessel and is pulled against an inner wall of the target vessel causing tenting of the thin tissue of the vessel wall. A graft vessel is then advanced to the anastomosis site and an end of the graft vessel is positioned adjacent and exterior of the target vessel. Staples are inserted through the tissue of the graft vessel and the target vessel by pivoting the arms of a staple holder towards the anvil. When the ends of the staples engage staple bending features on the anvil, the ends of the staples bend over securing the graft vessel and target vessel together.
