A video processing system generates and automatically updates videos. A client inputs a smart script that defines general preferences and information to include in a video. The video processing system generates a model of the story from the smart script. A story model comprises story beats that define order and characteristics of information that is presented in a story. The video processing system accesses client content (e.g., video clips, images, and testimonials from a client website) and assigns content items to story beats. The story model and associated content is rendered into a video. The video processing system can then adapt the story model in response to viewer feedback, external events, or other client-supplied parameters. Adapting the story model may include reordering, adding, or removing story beats, or altering parameter values associated with story beat characteristics. Thus, the video processing system can iteratively improve and update a video automatically.

Methods and apparatus are disclosed for treating body tissue whereby a section of tissue is drawn into contact with the open distal end of the first passageway of the apparatus. A tissue treatment fluid is introduced into the second passageway for treating the desired section of tissue retained within the first passageway. Methods and apparatus are also disclosed for positioning a medical device at a desired location within the heart. A portion of the apparatus is retained at a desired location of the heart and a medical device is extended through a passageway of the apparatus for contacting the heart at the desired location.

Apparatus and method are described for delivery of a treating element, such as a radiation source, through a catheter to a desired site in the vascular system of a patient, such as a coronary artery, for inhibiting the formation of scar tissue such as may occur in restenosis following balloon angioplasty. The apparatus includes an elongated flexible catheter tube having proximal and distal end portions, with a lumen extending therebetween, and a diameter sufficiently small for insertion in to a patient's vascular system. One or more treating elements, such as a capsule or pellet containing radioactive material, is positionable within the lumen and movable between the proximal and distal end portions under the force of liquid flowing through the lumen. A method for using such apparatus, including a method for using such apparatus simultaneously with a balloon angioplasty procedure, is disclosed.

An automatic fluid control having a first and second tube members and a slidable valve element capable of moving from a sealed closed position to an open position permitting fluid passage therethrough. In a preferred first embodiment, the elastomeric valve element is slidingly received with a passageway in the first tube. The valve element has a flange portion containing a plurality of slits that, when inverted and stretched, permit fluid to pass therethrough, but when closed, are in contact with the inner wall of the first tube and prevents fluid from passing therethrough. The valve element also can have a rigid plug attached within an opening in the top surface to present a preferably non-deformable contact point for a male luer tip, which, when pressed downward on the valve element, breaks a seal between the valve element and the first tube inner wall. In a second embodiment a toroidal shaped valve portion selectively forms a seal over a pin extending axially from the second tube member, the pin having a plurality of grooves in its surface to permit passage of fluid when the seal created by the valve element is broken. In a third embodiment, a valve element maintains a seal against a pin extending from the base of the second tube member and having a plurality of grooves. When the valve element is urged downward against the upward force of a spring, the pin grooves permit fluid flow through the second tube member.

A blood containment, visualization and tactile confirmation device is provided for use with a vascular entry needle. The device includes a visualization channel and/or a compliant outer wall portion which indicates whether a needle connected to the device has entered a selected blood vessel. The visualization channel is optionally vented to the outside to allow displaced air to escape, but has a gas permeable member to prevent blood from escaping. Alternatively, the visualization channel is substantially sealed such that it is not significantly vented. Preferably, a compliant outer wall portion defining the visualization channel pulses with changes in blood pressure, thereby providing a tactile indication that the needle tip is properly positioned. The device has a guideway with a barrier of elastomeric material which prevents blood from passing therethrough, but which allows passage of an elongated medical instrument such as catheterization apparatus. A flange may optionally be disposed within the compliant membrane to prevent excess depression of the compliant membrane.

A blood containment, visualization and tactile confirmation device is provided for use with a vascular entry needle. The device includes a visualization channel and/or a compliant outer wall portion which indicates whether a needle connected to the device has entered a selected blood vessel. The visualization channel is vented to the outside to allow displaced air to escape, but has a gas permeable member to prevent blood from escaping. The visualization channel may have one, two, or more stages, with a first stage chamber which indicates initial penetration of a selected blood vessel, and a second stage chamber which fills more slowly and indicates that the needle remains positioned within the blood vessel. A third stage chamber with entrapped air which compresses slightly due to the heartbeat may also be used. Preferably, a compliant outer wall portion pulses with changes in blood pressure, thereby providing a tactile indication that the needle tip is properly positioned. The device has a guideway with a barrier of elastomeric material which prevents blood from passing therethrough, but which allows passage of an elongated medical instrument such as catheterization apparatus. A flange may also be disposed within the compliant membrane to prevent excess depression of the compliant membrane.
