Abstract: Disclosed is a method for manufacturing a steerable instrument for endoscopic and/or invasive type applications, the instrument including an elongated tubular body having a proximal end part, a distal end part and an intermediate part between proximal and distal end parts, the proximal end part having at least one actuation proximal zone. The distal end part has at least one flexible distal zone, and the elongated tubular body is configured such that a movement of an actuation proximal zone is transferred to a corresponding flexible distal zone for a corresponding movement thereof. The elongated tubular body includes an inner, outer, and intermediate cylindrical elements having longitudinal elements between the inner and outer cylindrical elements. Inner, outer and intermediate cylindrical elements are coupled so movement of an actuation proximal zone is transferred by the longitudinal elements of one of the intermediate cylindrical elements to a corresponding flexible distal zone.

Abstract: A device that holds a radial sheath, catheter or similar structure in place during surgical procedures. The device has a strap configured to fit around a patient's wrist and a two-part section that includes a sheath holder or clamp. The clamp is configured to accept a free end of the sheath or other device and to allow the physician access to the open end of that sheath so that they can insert instruments through it. The second section contains a compression device that, when positioned over the puncture site, can be expanded such that it provides pressure and patent hemostasis to the site to stop bleeding. Adhesive surfaces with peel away releasable liners on one or more surfaces of the device allow the flap featuring the compression balloon to be folded over onto the flap containing the sheath clamp and hold it in place.

Abstract: A surgical apparatus includes a body, an ultrasonic transducer, a shaft, an acoustic waveguide, an articulation section, an end effector, and a restricting member. The ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations. The shaft couples the end effector and the body together. The acoustic waveguide is coupled with the transducer. The articulation section is operable to flex to thereby deflect the end effector from a longitudinal axis defined by the shaft. The restricting member is operable to restrict lateral deflection of the end effector. The restricting member is further operable to cooperate with a translating member to rigidize the articulation section when the end effector is aligned with the longitudinal axis. Such rigidization includes removing any “play” or other small movement that might otherwise be provided by the articulation section due to manufacturing tolerances and/or looseness between parts.

The gripping assembly defines a first opening for receiving a finger or a thumb of a user. The gripping assembly includes a first deformable feature that is configured to be moved in order to increase or decrease a cross-sectional area of the first opening. The shaft assembly extends distally from the gripping assembly. The end effector is positioned at a distal end of the shaft assembly and includes a first member. The pivoting member is pivotably coupled with the shaft assembly. The pivoting member is pivotable with respect to the first member of the end effector between an open position and a closed position to thereby clamp tissue between the first member and the pivoting member.

Abstract: A handle assembly for actuating an end effector includes a feedback mechanism for providing an audible and/or tactical response to indicate to the user that the handle assembly is fully actuated. The feedback mechanism may include a hammer member configured to strike a surface of the handle assembly to create the audible and/or tactical response.

Abstract: An assembly at a proximal end of an intravascular delivery system can allow the proximal end of a pull wire to move independently of a delivery tube. The assembly can generally include the pull wire, the delivery tube, a feature to prevent the proximal end of the pull wire from becoming inaccessible due to distal movement of the pull wire, and a feature to protect the proximal end of the pull wire from inadvertent, premature manipulation. When the intravascular delivery system is navigating tortuous vasculature, the proximal end of the pull wire can move distally in relation to the proximal end of delivery tube, relieving stress on the distal end of the pull wire. The proximal end of the pull wire can be protected from inadvertent manipulation during delivery and made available for manipulation once the distal end of the delivery system is in place.

Abstract: A hemorrhage control device for sealing a penetrating wound includes a tube having a connector engaged to a first end thereof. The connector can selectively engage a container so that the container is in fluidic communication with the tube. The container can selectively pressurize a fluid positioned therein so that the fluid is selectively dispensable through the tube. A shell is engaged to a second end of, and in fluidic communication with, the tube. The shell is selectively expandable from a compacted configuration wherein the shell is substantially circumferentially equivalent to the tube. The shell can be at least partially inserted into a penetrating wound in a mammal, such as a bullet wound. The shell then can be selectively expanded, as the fluid is dispensed from the container through the tube, so that the shell contacts a surface of the penetrating wound to control hemorrhaging.
