Methods For Maintaining A Filtering Device Within A Lumen

US Patent:
2013028, Oct 24, 2013
Filed:
Jun 17, 2013
Appl. No.:
13/919630
Inventors:
Eric JOHNSON - Woodside CA, US
Thomas J. FOGARTY - Portola Valley CA, US
Frank ARKO - Plano TX, US
Jeff ELKINS - Woodside CA, US
Martin SEERY - San Rafael CA, US
International Classification:
A61F 2/01
US Classification:
606200
Abstract:
In one embodiment of the present invention there is provided a method of filtering blood flow in a lumen by positioning an open loop filter support structure within a lumen; maintaining a position of the open loop filter support structure within the lumen using radial force generated by the open loop filter support structure; and filtering blood flow in the lumen using a filter supported by the open loop filter support structure. In one aspect, there is also applying radial force generated by the open loop filter support structure along the axial dimension of the lumen. In another embodiment of the present invention there is provided a method of providing a filter across a lumen flow path by providing a filter support structure having a first end, a crossover section, and a second end; and fixing the position of the filter support structure within the lumen by positioning the first end against a first portion of the lumen and positioning the second end against a second portion of the lumen; and using the filter support structure to provide a filter across the lumen flow path. In one aspect, the ends do not pierce the lumen surface.

Jeff Elkins - Woodside CA, US
Martin Seery - San Rafael CA, US
International Classification:
A61M 29/00
US Classification:
606200000
Abstract:
In one embodiment of the present invention there is provided a method of deploying within a lumen a filter having a material capture structure and a support structure by positioning the filter within the wall of a lumen; and deploying the filter into contact with the lumen by placing the material capture structure across the lumen flow path as one support structure element extends in a clockwise manner along the lumen wall and another support structure element extends in a counter clockwise manner along the lumen wall. In another embodiment of the present invention there is provided a method of positioning within a lumen a filtering device having a filter and a filter support structure by advancing the filtering device along the lumen while the filter and the filter support structure are in a stowed configuration; releasing the filter and the filter support structure from the stowed configuration so that opposing spiral elements of the filter support structure are in atraumatic contact with the lumen and the filter is positioned across the lumen flow path. In another embodiment of the present invention there is provided a method of deploying and retrieving a filter within a vessel by deploying the filter into the vessel from a delivery sheath having a first diameter; and retrieving the filter using a recovery sheath having a second diameter no more than 2 Fr larger than the first diameter.

Endoluminal Filter With Fixation

US Patent:
2013001, Jan 10, 2013
Filed:
Jul 19, 2012
Appl. No.:
13/553335
Inventors:
Eric Johnson - Woodside CA, US
Thomas Fogarty - Portola Valley CA, US
Frank Arko - Plano TX, US
Jeff Elkins - Woodside CA, US
Martin Seery - San Rafael CA, US
International Classification:
A61F 2/01
US Classification:
606200
Abstract:
An endoluminal filter including a first support member and a second support member attached to the first support member to form a crossover. A material capture structure extends between the first and second support members, the crossover and the first end or the second end of the first support member. The filter includes at least one tissue anchor on the first support member and the second support member. There is a method of positioning a filter within a lumen including advancing a sheath containing a filter through the lumen. Next, deploying a retrieval feature against the lumen wall while maintaining substantially all of a material capture structure of the filter within the sheath. Next, deploying the material capture structure of the filter from the sheath to a position across the lumen along with engaging the lumen wall with fixation elements positioned along the filter.
