Abstract

Insertable imaging devices and use methods thereof in minimally invasive medical procedures. Some insertable imaging devices are introduced and removed from an access port without disturbing or risking damage to internal tissue. Some insertable imaging devices are integrated with an access port, thereby allowing imaging of internal tissues within a vicinity of the access port, while enabling manipulation of surgical tools in the surgical field of interest. Some insertable imaging devices are integrated into an imaging sleeve that is insertable into an access port. Some insertable imaging devices perform imaging within an access port, wherein the imaging is based on one or more imaging modalities, including, but are not limited to, magnetic resonance imaging, ultrasound, optical imaging, such as hyperspectral imaging and optical coherence tomography, and electrical conductive measurements.

First claim
