Abstract: Mitral valve prolapse and mitral regurgitation can be treating by implanting in the mitral annulus a transvalvular intraannular band. The band has a first end, a first anchoring portion located proximate the first end, a second end, a second anchoring portion located proximate the second end, and a central portion. The central portion is positioned so that it extends transversely across a coaptive edge formed by the closure of the mitral valve leaflets. The band may be implanted via translumenal access or via thoracotomy.

Abstract: A tubular sheath for enclosing an expandable balloon attached to the distal portion of a catheter encloses and protects the expandable balloon. The tubular sheath is configured to be slidable and removable from the catheter. The tubular sheath may include a longitudinal splitting element that is removable as a result of a force applied to the longitudinal splitting element. The longitudinal splitting element is configured to split the wall of the tubular sheath in response to the force. Alternatively, the tubular sheath may include a gripping portion that has relatively poor cohesive strength to adjacent portions of the tubular sheath. The tubular sheath is configured to be removable in response to a force applied to the gripping portion.

Abstract: A user creates an event in a social networking system specifying a location, a time, and a guest list of other users invited to the event. The social networking system generates a page associated with the event that provides information about the event and identifies whether users have responded to invitations to the event. The content of the page may be customized for the user viewing the page to encourage the viewing user to attend the event. For example, the viewing user's relationship to and/or similar characteristics with other users on the guest list is determined and used by the social networking system to identify the users whose responses to invitations are shown to the viewing user via the page. Additionally, a notification method more prominently distributes acceptances of invitations to other users to encourage attendance.

Abstract: A social networking system user creates an album including a shared collection of content (a “shared album”) and associates a privacy model with the shared album. The privacy model specifies additional users of the social networking system authorized to access content items in the shared album and specifies types of actions users authorized to access content items in the shared album are permitted to perform to content items in the shared album. Notifications describing actions associated with content items in a shared album may be presented to users authorized to access the shared album. The social networking system may prompt a user to create a shared album containing based on actions performed by the user or performed by connected to the user.

Abstract: Social networking system users may create events where a group of other users invited to the event meet at a specified time and location. The social networking system suggests users to invite to an event based on a prediction that the users would attend the event if invited. Various factors may be used to make the prediction, such as an affinity between the inviting user and the other users, the availability of the other users at the time of the event and/or the proximity of the other users to the location of the event. An inviting user receives the suggested users and selects suggested users to invite to the event or invitations may be automatically sent to the suggested users by the social networking system.

Abstract: An electronic device of a second user receives, from a first user, a first message. Subsequent to receiving the first message, the electronic device sends, to the first user, a second message responsive to the first message, wherein the second message is selected from a set of predefined first-reply messages. The set of predefined first-reply messages is based on first-reply factors for the second user, including content from one or more messages between the first user and the second user, and including one or more of: relationship characteristics between the first user and the second user, information provided by the first user and/or the second user to a social network, profile characteristics of the first user and/or the second user, environmental characteristics of the first user and/or the second user, and/or technical characteristics of the electronic device of the first user and/or the second user.

Abstract: A social networking system suggests events for a target user based on stored data in the social networking system related to the target user and to events. The social networking system may suggest events based on the target user's affinity for, connections with, or interactions with objects in the social networking system connected to or otherwise associated with the events. For example, an event is suggested to a target user if users connected to the target user already accepted an invitation to the event. As another example, an event organized by a particular entity is suggested to the target user because of interactions between the target user and other content provided by the entity. Invitations to suggested events may be presented to the target user via a client device, allowing the target user to easily join a suggested event.
