Claims19
A coaxial guide device comprising:
- an adapter comprising a vacuum channel;
- and
- a needle drive comprising a needle disposed in a needle guide.
A method of delivering material to an anatomical space of interest comprising:
- visualizing the anatomical space of interest using an optical sensor stabilized by a coaxial guide device comprising a vacuum channel;
- accessing the anatomical space of interest using a needle disposed in the coaxial guide device;
- and
- depositing material in the anatomical space of interest using a pair of thin, elongate strips of flexible material and thin layer of elastic material surrounding the pair of thin, elongate strips of flexible material form a flexible, expandable tube, wherein an elongate lumen extends between the pair of thin, elongate strips of flexible material for depositing the material.
