Endoprosthesis Having Improved Strain Distribution

View page
US Patent:
8496698, Jul 30, 2013
Filed:
Jul 15, 2010
Appl. No.:
12/836767
Inventors:
Chad J. Abunassar - San Francisco CA, US
Assignee:
Abbott Cardiovascular Systems, Inc. - Santa Clara CA
International Classification:
A61F 2/06
US Classification:
623 115
Abstract:
An endoprosthesis for delivery in a body lumen can be configured to inhibit structural fatigue, crack formation, and elastic recoil while providing improved crimping and expansion uniformity and radial strength. As such, the endoprosthesis can include at least one multi-stage crest element connecting adjacent bar arms. The multi-stage crest element and, optionally, the connection or transition between the multi-stage crest element and the bar arms can form a plurality of undulations or curves to improve the distribution of the strains experienced by the endoprosthesis. The improved strain distribution can improve the structural integrity and prevent failure of the endoprosthesis.

Stent And Method For Making A Stent

View page
US Patent:
20100106242, Apr 29, 2010
Filed:
Oct 23, 2008
Appl. No.:
12/257327
Inventors:
Arzu M. Ozkan - Mountain View CA, US
Chad Joseph Abunassar - San Francisco CA, US
Assignee:
Abbott Cardiovascular Systems Inc. - Santa Clara CA
International Classification:
A61F 2/06
A61B 19/00
US Classification:
623 142, 623 115, 623 144, 128898
Abstract:
A stent includes a body, a layer of therapeutic agent over at least a section of the body, and a sealant layer over the layer of therapeutic agent. The sealant layer includes a through hole that allows release of the therapeutic agent of the therapeutic agent layer through the through hole when the stent is deployed in a blood vessel.

Aspect Ratio For Stent Strut Design

View page
US Patent:
20110251672, Oct 13, 2011
Filed:
Apr 12, 2010
Appl. No.:
12/758197
Inventors:
CHAD J. ABUNASSAR - San Francisco CA, US
Assignee:
ABBOTT CARDIOVASCULAR SYSTEMS INC. - Santa Clara CA
International Classification:
A61F 2/82
US Classification:
623 116, 623 115, 623 142
Abstract:
An intravascular stent is provided to be implanted in coronary arteries and other body lumens. The stent includes stent struts that have a transverse cross-section that is substantially rectangular and an aspect ratio in the range of 0.9 to 1.0 to 1.4 to 1.0. This range of aspect ratios for the stent struts minimizes out of plane twisting of the struts or projecting edges of the struts when the stent is expanded from a compressed diameter to an expanded diameter in a coronary artery.

Optimal Ratio Of Polar And Bending Moment Of Inertia For Stent Strut Design

View page
US Patent:
20110264193, Oct 27, 2011
Filed:
Apr 22, 2010
Appl. No.:
12/765080
Inventors:
CHAD ABUNASSAR - San Francisco CA, US
Assignee:
ABBOTT CARDIOVASCULAR SYSTEMS INC. - Santa Clara CA
International Classification:
A61F 2/82
US Classification:
623 115
Abstract:
An intravascular stent is provided to be implanted in coronary arteries and other body lumens. The transverse cross-section of at least some of the stent struts have a ratio of polar and bending moments of inertia, which results in optimal resistance to stent twisting. This resistance to twisting ratio for the stent struts minimizes out of plane twisting of the struts or projecting edges of the struts when the stent is expanded from a compressed diameter to an expanded diameter in a coronary artery.

Stent Having Optimized Expansion Ratio

View page
US Patent:
20110295356, Dec 1, 2011
Filed:
May 28, 2010
Appl. No.:
12/789901
Inventors:
Chad Abunassar - San Francisco CA, US
Assignee:
ABBOTT CARDIOVASCULAR SYSTEMS INC. - Santa Clara CA
International Classification:
A61F 2/82
US Classification:
623 115
Abstract:
An intravascular stent has an elongated tubular member that has a manufactured inner diameter and a manufactured outer diameter. The nominal expansion outer diameter (implanted diameter) is approximately 1.618 times larger than the manufactured outer diameter, which is referred to the Golden Ratio. The Golden Ratio provides for optimal crimping and expansion aesthetics, stent expansion uniformity, and uniform coatability for stent receiving a drug coating.

Filed:
Jul 18, 2012
Appl. No.:
13/552490
Inventors:
Chad Abunassar - San Francisco CA, US
Assignee:
ABBOTT CARDIOVASCULAR SYSTEMS INC. - Santa Clara CA
International Classification:
A61F 2/86
US Classification:
623 115
Abstract:
A stent and method comprising inserting within a vessel an unexpanded stent that includes a first zone comprising a plurality of adjacent ring elements, not less than three in number, that are distributed along the stent with a first spacing, and a second zone comprising a plurality of adjacent ring elements that are distributed along the stent with a second spacing, and expanding the stent to cause the plurality of ring elements in the first zone to redistribute to a third spacing that is smaller than the first spacing and to cause ring elements in the second zone to distribute to a fourth spacing larger than the first spacing.
