Abstract: A surgical fixation tool (10) includes at least one fixation member (12) which protrudes from a leg (16) of a proximal grasping portion (20). The at least one fixation member (12) includes a needle (28) with a sharp distal tip (29). The needle (28) protrudes distally from a support structure (30) that includes one or more sloped support surfaces (34, 36) that are sloped with respect to a needle shaft (27).

Abstract: The present invention discloses a device suitable for delivery of a fluid composition to an eye, especially therapeutic compositions, comprising: a hollow needle with a bore having a proximal end and a distal end, said distal end configured to pass into a passage in a sclera of an eye, said bore configured to function as a conduit for a fluid from said proximal end to said distal end, and a solid separator having a distal tip, configured to move inside said bore of said hollow needle allowing said distal tip of said separator to protrude from said distal end of said needle.

Abstract: Provided is a device for injection into an interlayer of an organ of a subject. The device includes a needle having a size transitional portion terminating in a sharp needle distal tip. The device also includes an elongated tissue separator that is shiftable in the needle lumen. An actuator shifts the tissue separator in the needle lumen between a first position, in which the separator distal tip is fixedly positioned proximally to the needle distal tip, and a second position in which the separator distal tip is fixedly positioned a predetermined distance distally from the needle distal tip.
