An implantable medical device having at least one compliant retention member configured not only to resist migration of the device with respect to its deployment site, but also to conform to anatomical forces applied thereto. The retention member may present a convex tissue-contacting surface to tissue at the deployment site and to which anatomical forces may be applied. The retention member may be compressible upon application of radially-inwardly directed anatomical forces thereto, but is sized, shaped, configured, and/or dimensioned to withstand forces tending to cause migration of the implantable medical device even when being compressed radially-inwardly. As such, the implantable medical device withstands forces applied thereto without building up internal stresses which may result in material fatigue.

The optical pressure sensor may include a sensor body and a deflectable membrane coupled to the sensor body. The deflectable membrane may include a polymer. An optical fiber may be coupled to the sensor body and may extend proximally therefrom. A pressure equalization channel is formed in the optical fiber, the sensor body, or both.

Abrégé

An accessory device for an endoscope includes a cap attached to a shaft of the endoscope, the cap extending along a first axis, a first tip coupled to the cap and movable relative to the cap between a deployed configuration and a non-deployed configuration, and a first shaft defining a lumen and extending proximally from the first tip. In the deployed configuration, the first tip extends along a second axis that is offset from the first axis, and in the non-deployed configuration, the first tip extends along a third axis that is offset from the first axis.
