Assignee:

Abbott Cardiovascular Systems Inc. - Santa Clara CA

International Classification:

B29C 65/02

US Classification:

156196

Abstract:

Methods for making scaffolds for delivery via a balloon catheter are described. The scaffold, after being deployed by the balloon, provides a crush recovery of about 90% after the diameter of the scaffold has been pinched or crushed by 50%. The scaffold structure has patterns that include an asymmetric or symmetric closed cell, and links connecting such closed cells.

International Classification:

A61C 300

US Classification:

433 8, 433 9

Abstract:

Disclosed herein is an orthodontic article, a method of making an orthodontic article and an apparatus for making the orthodontic article. The orthodontic article is made by laser welding the work piece, comprising a bracket body and a the pad, together. The article thus formed includes a laser-welded seal around the perimeter of the adjoining areas between the pad and the bracket body. In an exemplary embodiment the apparatus of the invention, makes a series of closely spaced spot welds. The spot welds, in an exemplary embodiment, are significantly overlapped that they form a seal around the entire perimeter of the work piece adjoining areas. The spot welds, in an exemplary embodiment, are significantly overlapped that they form a hermetic seal between the pad and the bracket body. In other exemplary embodiments, the process of manufacturing orthodontic articles is automated and controlled by a computer and computer software.

A61M 25/09

Abstract:

An intravascular delivery system includes a delivery sheath capable of transmitting a predetermined tension or compression force in a longitudinal direction while maintaining flexibility to navigate tortuous anatomy. A method of delivering a medical device includes inserting an intravascular device delivery system including a delivery sheath having a continuous spine into a bodily lumen. A distal longitudinal force is applied to the delivery sheath. The distal force is transmitted through the continuous spine and across one or more slit cuts of the delivery sheath. A proximal longitudinal force is applied to the delivery sheath. The proximal longitudinal force is transmitted through the continuous spine of the delivery sheath.

US Classification:

21912172, 21912167

Abstract:

A laser system including various optical components providing for beam alignment and process monitoring of a stent cutting process is described. The various aspects of the invention provide for monitoring of a beam of laser light reflected from the surface of a stent tube so as monitor the properties of the cutting beam, location of the beam, system cleanliness, optical defects in the system, and cutting efficiency of the laser.
