Patent number: 9566181Abstract: Devices and methods for gastrointestinal bypass are described. A gastrointestinal bypass device includes a gastrointestinal cuff and a gastrointestinal sleeve. The cuff may be configured to be attached in the esophagus, and may be sufficiently flexible to expand and collapse to conform with the inside of the esophagus to allow the esophagus to function substantially normally. The sleeve is configured to be coupled to the cuff, and may be made of a material that is floppy or flaccid but does not substantially expand radially.Type: GrantFiled: May 31, 2012Date of Patent: February 14, 2017Assignee: ValenTx, Inc.Inventors: Jesse N. Nelson, Heather Benoit, Christopher Thierfelder

Publication number: 20140207159Abstract: One or more tissue anchors may be delivered first without being coupled to an anchored device. An anchored device may be delivered second, and then coupled to the tissue anchors. This may enhance placement accuracy of tissue anchors, as well as facilitate delivery of tissue anchors. The tissue anchors include anchor couplings configured to be coupled to one or more device couplings of the anchored device.Type: ApplicationFiled: January 24, 2014Publication date: July 24, 2014Inventors: Sean MILLER, Cole CHEN, Terry DAHL, Johann NEISZ, Jesse N.

Patent number: 8317861Abstract: A voice prosthesis comprising a tubular body portion, a valve and a valve seat disposed within the body portion. The valve seat is further comprised of a medical grade elastomer containing a dispersion of an antimicrobial agent. This valve seat extends the life of the prosthesis by retarding the growth of microorganisms. The body portion of the prosthesis may also contain an antimicrobial agent at a concentration that is non-toxic to the tissue it contacts.Type: GrantFiled: March 29, 2005Date of Patent: November 27, 2012Assignee: Helix Medical, LLCInventors: Jeffrey L. Goldberg, Edmund V. Seder, Jesse N. Nelson, Juan M. Madrigal

Publication number: 20110264214Abstract: A voice prosthesis device includes a barrel defining a passageway, a tracheal flange adjacent a tracheal end of the barrel and an esophageal flange adjacent an esophageal end of the barrel. The passageway includes a first stop extending inwardly from a sidewall of the passageway between the tracheal and esophageal ends and a plurality of second stops extending inwardly from the sidewall of the passageway between the first stop and the esophageal end of the passageway. A valve mechanism is located between the first and second stops and permits flow through the passageway from the tracheal end and impedes flow through the passageway from the esophageal end.Type: ApplicationFiled: July 1, 2011Publication date: October 27, 2011Applicant: HELIX MEDICAL, LLCInventor: Jesse N. Nelson

Patent number: 7520897Abstract: Microbial growth on the surface of a valve of a voice prosthesis and optionally the cartridge or ring supporting the valve, is inhibited by providing antimicrobial activity at a level sufficient to retard growth of a microbial film by dispersing an inorganic antimicrobial agent such as silver oxide or an organic antimicrobial agent such as triclosan or butyl paraben dispersed in a medical grade silicone elastomer. The valve, ring or cartridge is in contact with body fluids containing microorganisms and nutrients therefor. The antimicrobial surface can interfere with or inhibit the growth of a biofilm, bacterial layer or a yeast layer. The body of the prosthesis may also contain an antimicrobial surface as long as it is non-toxic to the tissue it contacts.Type: GrantFiled: November 15, 2004Date of Patent: April 21, 2009Assignee: Helix Medical, LLCInventors: Edmund V. Seder, Jesse N. Nelson

Patent number: 7393547Abstract: A method for making an elastomeric material containing an antimicrobial composition such as a dispersion of silver oxide that is suitable for implantation within the body. The elastomer made in accordance with this method extends the amount of work-time available for processing the elastomer into an article as compared with the work-time available when using prior art compounding methods.Type: GrantFiled: August 19, 2004Date of Patent: July 1, 2008Assignee: Helix Medical, LLCInventor: Jesse N. Nelson

Publication number: 20020193879Abstract: Microbial growth on a first surface of a medical device in indirect contact with tissue such as a prosthesis and particularly a valve, cartridge or ring in a voice prosthesis, is inhibited by providing antimicrobial activity at a level sufficient to retard growth of a microbial film by dispersing an antimicrobial agent such as triclosan or butyl paraben dispersed in a medical grade silicone elastomer. The valve, ring or cartridge is in contact with body fluids containing microorganisms and nutrients therefor. The antimicrobial surface can interfere with or inhibit the growth of a biofilm, bacterial layer or a yeast layer. The body of the prosthesis may also contain an antimicrobial surface as long as it is non-toxic to the tissue it contacts.Type: ApplicationFiled: April 11, 2001Publication date: December 19, 2002Inventors: Edmund V.
