Implantable adjustable sphincter system
First Claim
1. An implantable adjustable sphincter system for treatment of a medical condition, comprising:
- a band configured to encircle a portion of an anatomical passageway and to resiliently receive and hold fluid;
a manual pump responsive to manual palpation;
a reservoir in fluid communication with said manual pump; and
a valve assembly in fluid communication with said band and said manual pump, said valve assembly comprising;
a first configuration, wherein said first configuration permits fluid from the band to flow toward the reservoir, wherein said first configuration prevents fluid from flowing from the reservoir toward the band, and a second configuration, wherein said second configuration permits fluid from the reservoir to flow toward the band, wherein said second configuration prevents fluid from flowing from the band toward the reservoir;
wherein said valve assembly is operable to be manually switched between said first configuration and said second configuration;
wherein said manual pump is in fluid communication with said valve assembly and said reservoir, wherein said manual pump is manually operable to transfer fluid between said reservoir and said band in response to manual palpation when said valve assembly is in said second configuration.

Abstract
An implantable adjustable sphincter system is comprised of a band configured to encircle a portion of an anatomical passageway, a manual pump, a reservoir in fluid communication with the pump, and a valve assembly in fluid communication with the band and the manual pump. The valve assembly is comprised of a first configuration and a second configuration, and is operable to be manually switched between configurations. The first configuration only permits fluid to flow from the band toward the reservoir. The second configuration only permits fluid to flow from the reservoir toward the band. The manual pump is in fluid communication with the valve assembly and the reservoir, and is manually operable to transfer fluid between the reservoir and the band when the valve assembly is in the second configuration.

10. An implantable adjustable sphincter system for treatment of a medical condition of a patient comprising:
-
(a) a band configured to encircle a portion of an anatomical passageway and to resiliently receive and hold fluid;
(b) a manual pump responsive to manual palpation;
(c) a reservoir in fluid communication with said manual pump; and
(d) a valve assembly in fluid communication with said band and said manual pump, said valve assembly comprising;
