  • Stent with a bio-resorbable connector
    Patent number: 10449066
    Abstract: A stent including a plurality of curved sections and a connector. The curved sections surround a longitudinal axis to define a tube portion and are distributed along the longitudinal axis to form a helix. The connector includes a bioresorbable material and is positioned between two adjacent curved sections. The stent has a spring constant that changes to a different spring constant after exposure to biological material.
    Type: Grant
    Filed: July 17, 2017
    Date of Patent: October 22, 2019

  • Stent with a bio-resorbable connector
    Patent number: 8647379
    Abstract: A helical stent having bio-resorbable connecting members connecting sections of the stent. The connecting members provide various spring rates or spring constants to the stent, and permit a change in the flexibility of the stent subsequent to implantation while maintaining the unitary design of the stent.

  • Stent with bio-resorbable connector and methods
    Patent number: 7862607
    Abstract: A helical stent having bioresorbable connecting members connecting sections of the stent. The connecting members provide various spring rates or spring constants to the stent, and permit a change in the flexibility of the stent subsequent to implantation while maintaining the unitary design of the stent. A method of making the helical stent includes forming a tube with a section made of a bioresorbable material prior to forming the stent.
