Abstract: According to an embodiment, the present subject matter describes a device for delivery of one or more fluids in to a target site. The fluid delivery device (100) includes a housing (105, 205), a shaft (110), which may 125 be disposed inside the housing (105, 205) to form at least one fluid chamber (115, 210) therebetween. Further, the fluid chamber (115, 210) is adapted to receive the one or more fluids. The fluid delivery device (100) further includes a plunger (120, 225) provided at a first end (125) of the housing (105, 205). The plunger (120, 225) may be coupled to the shaft (110) and may be adapted to move inside the housing (105, 205) to deliver the one or more fluids to the target site (405).

Abstract: A biopsy needle, a biopsy needle assembly and methods to perform biopsy are disclosed. The biopsy needle includes a primary needle section formed as a hollow tube; a converging section accurately converging from a wall of the hollow tube of a first end of the primary needle section to form a piercing tip; a secondary needle section; and a body. The converging section of the biopsy needle further includes an opening on a lateral wall having a third cutting edge. The body of the biopsy needle is coupled to a second end of the primary needle section and may be coupled to an actuator to control a linear and a rotational movement of the biopsy needle.

Abstract: The present subject matter relates to a biopsy needle assembly (102) for performing biopsy. In one implementation, the biopsy needle assembly (102) includes a biopsy needle (106) which further includes a primary needle section (202), formed as a hollow tube, where the primary needle section (202) comprises a first end and a second end; a converging section (204) arcuately converging from wall of the hollow tube of the first end of the primary needle section to form a piercing tip (108). The converging section (208) further includes an opening on lateral wall to form cutting edges to extract the tissue sample. The biopsy needle (106) also includes a body (208) coupled to the second end of the primary needle section (202), where wherein the body (208) may be adapted for coupling to an actuator to initiate a movement of biopsy needle (106).
