Abstract
This invention relates to an implantable device for a physiologic sensor, comprising an implantable expandable anchor, a bridge on which the sensor is secured, as well as an optional adapting ring. The invention also relates to a method of monitoring bodily functions using the anchor and sensor. The anchor is compressed and the bridge assumes an elongated shape during delivery to a target lumen. Upon deployment at the target site, the anchor expands and the bridge bows into the interior lumen of the expanded anchor, distancing the sensor from the vessel wall. This invention also relates to a method of manufacturing said device and a method of implanting a sensor.
Claims26
An implantable device comprising:
- an anchor having a first serpentine ring and a second serpentine ring defining a lumen along a longitudinal axis, and having a compressed configuration and an expanded configuration, and
- a bridge having a first end attached to said first serpentine ring and a second end attached to said second serpentine ring, said first end is separated from the second end at a first distance and said bridge is aligned with the longitudinal axis of the anchor when said anchor is in the compressed configuration, and said first end is separated from the second end at a second distance when said anchor is in the expanded configuration, and said bridge protrudes into said lumen when said anchor is in the expanded configuration, said second distance is less than said first distance.
An implantable device comprising:
- an anchor having a first serpentine ring having a plurality of peaks and valleys and a second serpentine ring having a plurality of peaks and valleys, wherein the plurality of valleys of the first serpentine ring are connected to the plurality of peaks of the second serpentine ring, said anchor having a compressed configuration and an expanded configuration;
- and a bridge having a first end and a second end, said first end attached to one of the plurality of peaks of the first serpentine ring and said second end attached to one of the plurality of valleys of the second serpentine ring, said one of the plurality of peaks of the first serpentine ring is separated from said one of the plurality of valleys of the second serpentine ring by a first distance in the compressed configuration, and said one of the plurality of peaks of the first serpentine ring is separated from said one of the plurality of valleys of the second serpentine ring by a second distance in the expanded configuration, said second distance is less than said first distance, wherein said bridge is in a flat position when said anchor is in the compressed configuration, and said bridge is in a bowed position and protrudes into a lumen of the anchor when said anchor is in the expanded configuration.
