A pellet delivery system is provided that comprises a needle having an inner surface defining a passageway. The needle has a first portion that extends along a longitudinal axis and a curved second portion comprising an opening that is in communication with the passageway. The second portion extends transverse to the longitudinal axis. A pellet is positioned in the passageway. A plunger is slidably positioned in the passageway. The plunger comprises a shaft having a rounded tip configured to push the pellet through the first and second portions and out of the opening without the pellet becoming stuck within the passageway or the opening. Implants, systems, constructs, instruments and methods are disclosed.

Enhanced stylet for drug depot injector

An injection includes a tube having opposite first and second ends. A hub is coupled to the first end. A sheath is coupled to the tube and the hub. The hub is movable relative to the tube to move the sheath between a first orientation in which the sheath covers an orifice in the second end and a second orientation in which the sheath is spaced apart from the orifice. Kits and methods of use are disclosed.

Drug pellet injector needle and method technical field

The invention provides improved devices and apparatuses and related methods for sensing differences in pressure or other parameters in the environment of the body of a patient during passage of the device through one or more tissues. In one aspect, the devices and apparatuses of the invention are configured to sense differences in the environment of the body of the patient as the device passes through tissue adjacent to the epidural space to tissue of the epidural space. In one aspect, a dual cannula device comprising one or more sensors connected to a signaling component is provided for sensing passage into of the device into the epidural space and positioning therein. Methods of using same are also provided.

Multi-cannula sensing device

A cryoprobe is used during surgery in a human body to remove unwanted tissue. The cryoprobe includes a first gas supply line and a second gas supply line for delivering a supply of cryogenic gas from at least adjacent a proximal end to at least adjacent a distal end of the cryoprobe. The cryoprobe further includes a first gas return line and a second gas return line for returning the supply of cryogenic gas from at least adjacent the distal end to at least adjacent the proximal end of the cryoprobe. At least a portion of the first gas supply line is received in the first gas return line. A transition portion having at least one internal cavity and an aperture from the at least one internal cavity to an exterior portion of the transition portion is also included in the cryoprobe. The transition portion is provided to facilitate at least the transfer of the cryogenic gas from the second gas return line to the first gas return line, so that the cryogenic gas can flow adjacent the first gas supply line on its way to the proximal end of the cryoprobe.
