  • Publication number: 20110233259
    Abstract: A surgical buttress includes a body portion and a band disposed on each of the distal and proximal ends thereof. The surgical buttress is configured to attach to an end effector of a surgical stapling apparatus. The body portion, having perforations disposed thereon, overlies the working surface of one of the first or second jaws of the end effector. A resilient portion extends transversely beyond the side edges of the first or second jaws. Each band remains attached to the end effector following the firing thereof. The proximal band is removably attachable to a hook feature disposed on one of the first or second jaws of the end effector. The surgical buttress can be made from suitable degradable or non-degradable materials. One embodiment contemplates a detachable and disposable single use loading unit. A method of attaching the surgical buttress to a surgical apparatus is also envisioned.

  • Patent number: 7938851
    Abstract: Devices and methods are provided for operating and controlling an interventional element on an interventional catheter. The interventional element may be a stent or series of stents, a balloon, or any other interventional element for which length control is necessary or desirable. A handle member includes an elongated body and an actuator knob that rotates around the longitudinal axis of the body. Rotational movement of the actuator knob is translated to rotational movement of one or more lead screws by a system of gears, rollers, or combinations of gears and rollers. Each of one or more axially moveable members is positioned on a lead screw and attached to a portion of the catheter shaft in order to provide the ability to advance or retract the portion of the catheter shaft.

  • Publication number: 20110004285
    Abstract: An implantable medical device (IMD) can include implantable pulse generator (IPG) devices, implantable cardioverter-defibrillators (ICD), cardiac resynchronization therapy defibrillator devices, neurostimulators or combinations thereof. In one example, the IMD can include a body assembly, which can provide at least one electrical signal corresponding to a therapy. The IMD can also include a cardiac lead assembly, which can have a proximal portion and a distal portion. The proximal portion of the cardiac lead assembly can be in communication with the body assembly to receive the therapy and the distal portion can be adapted to be coupled to an anatomical structure to transmit the at least one electrical signal to the anatomical structure. The proximal portion of the cardiac lead assembly can have a first stiffness and the distal portion can have a second stiffness. The first stiffness can be greater than the second stiffness.
