Filed:

May 27, 2011

Appl. No.:

13/118311

Inventors:

Annie P. Liu - Cupertino CA, US
Jason Phillips - Lake Elsinore CA, US
Mark C. Johnson - Murrieta CA, US

Assignee:

Abbott Cardiovascular Systems Inc. - Santa Clara CA

International Classification:

A61M 29/00

US Classification:

60410305

Abstract:

A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. A sheath pair is placed over the crimped scaffold after crimping to reduce recoil of the crimped polymer scaffold and maintain scaffold-balloon engagement relied on to hold the scaffold to the balloon when the scaffold is being delivered to a target in a body. The sheath pair is removed by a health professional before placing the scaffold within the body.

Ashish Gupta - Mountain View CA, US

International Classification:

G06F 16/901

Abstract:

Various embodiments include a classification platform system. A user can define a classification experiment on the classification platform system. For example, the user can define an input data space by selecting at least one of data sources interfaced with the classification platform system and defining a workflow configuration including a directed graph (DG) connecting a plurality of transformation blocks to represent an experiment workflow. The DG can specify how one or more outputs of each of the transformation blocks are fed into one or more other transformation blocks. The DG can be executed by various types of computation platforms. The classification platform system can schedule the experiment workflow to be executed on a distributed computation platform according to the input data space and the workflow configuration.

Abstract:

In one embodiment, a method includes defining an input data space, defining a directed graph (DG) connecting a plurality of transformation blocks to represent an experiment workflow, wherein at least one of the plurality of transformation blocks includes logic to dynamically modify the DG during execution of the experiment workflow, formatting the DG and the input data space into a data structure such that the data structure is interpretable by a plurality of different computation platforms, scheduling a distributed computation platform selected from the plurality of different computation platforms to execute the experiment workflow according to the input data space and the DG, and imperatively programming computing nodes of the distributed computation platform to execute the experiment workflow based on the DG if at least one of the transformation blocks dynamically modifies the DG during the execution of the experiment workflow.

Abstract:

A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. A sheath is placed over the crimped scaffold after crimping to reduce recoil of the crimped polymer scaffold and maintain scaffold-balloon engagement relied on to hold the scaffold to the balloon when the scaffold is being delivered to a target in a body. The sheath is removed by a health professional either by removing the sheath directly or using a tube containing the catheter.

International Classification:

A61F 2/91
A61L 31/04
A61L 31/14

Abstract:

A method of accelerated aging of bioresorbable polymer scaffolds including exposing the scaffold to water is disclosed. The scaffold is exposed to water at a controlled temperature for a selected aging time. The functional outputs, such as radial strength, expandability, and % recoil obtained from aged scaffolds predict those of real-time aging of the scaffold. The accelerated aging factor, which is the required shelf life divided by the aging time, is significantly higher for poly(L-lactide) scaffolds tested than thermal aging.

International Classification:

A61F 2/82
A61F 2/915
A61L 31/04
A61L 31/18

Abstract:

A scaffold includes a radiopaque marker connected to a strut. The marker is retained within the strut by one or more of a mechanical interference fit, a polymer coating or melt, and/or by friction. The marker can take the form of a bead, rivet or snap-in marker, or a tube deformed when attached to the strut. The strut is made from a tube. The strut has a thickness of about 100 microns.

International Classification:

G06F 17/30

Abstract:

An online system ranks topic-groups for users and presents content items in topic-based feeds. A topic group corresponds to one or more topic(s) and can be used to generate a feed for presenting the content items related to the topic(s). For a particular user, the topic groups are ranked according to the likelihood of the user interacting with content items included in the topic groups. The topic groups are ranked using information of the users and/or users' historical interaction data such as click-based interaction data, post-based interaction data, or engagement-based interaction data. The online system generates and provides a user interface for presenting the topic groups to the client device. Content items that are related to the topic(s) corresponding to the topic group are presented in each topic-based feed such that the user can switch between different topic-based feeds.
