SUBCUTANEOUS TUNNELING AND IMPLANTATION TOOLS FOR A DISK-SHAPED SENSOR
Tunneling and implantation tools that may be used to implant a sensor within a living animal. For example, the sensor may be implanted in subcutaneous tissue below the skin. The sensor may be disk-shaped and may be capable of being compressed (e.g., wrapped) in a more cylindrical shape. The sensor may or may not be able expand on its own (i.e., to force tissue apart to accommodate the sensor in its full disk-shape) after insertion into the living animal. The tunneling tool may have a flat and wide tip, a vibration device, arms attached to a rod at its tip, a spring in a hollow tube at the end of a rod, and/or oscillating teeth. The implantation tool may have jaws that clamp and then release the sensor and/or rods that insert into channels of the sensor and spread apart to assist in opening up a compressed sensor.
1 . A subcutaneous tunneling tool for implanting a disk-shaped sensor, the tunneling tool comprising:
a handle;
a rod extending from the handle, wherein the rod includes a tip at the end of the rod; and
a vibration device configured to vibrate the tip.
2 . The tunneling tool of claim 1 , wherein the tip is flat and wide.
3 . A subcutaneous tunneling tool for implanting a disk-shaped sensor, the tunneling tool comprising:
a handle;
a rod extending from the handle, wherein the rod includes:
a tip at the end of the rod; and
one or more arms attached to the rod at the tip; and
an actuator configured to force the one or more arms away from the rod.
4 . The tunneling tool of claim 3 , wherein the one or more arms are spring-loaded.
5 . The tunneling tool of claim 3 , wherein the actuator is a slider.
6 . A subcutaneous tunneling tool for implanting a disk-shaped sensor, the tunneling tool comprising:
a handle;
a rod extending from the handle, wherein the rod includes:
a hollow tube at the end of the rod; and
a spring that, when confined in tension in the hollow tube, is compressed and, when relieved of tension out of the hollow tub, fans open; and
an actuator configured to force the spring out of the hollow tube and relieve the spring of tension.
7 . The tunneling tool of claim 6 , wherein the actuator is a slider.
8 . A subcutaneous tunneling tool for implanting a disk-shaped sensor, the tunneling tool comprising:
a handle;
a rod extending from the handle, wherein the rod includes:
a tip at the end of the rod; and
teeth configured to oscillate in and out of the rod when actuated.
9 . The tunneling tool of claim 8 , wherein the teeth, when actuated, extend from the rod and retract into the rod.
10 . A subcutaneous implantation tool for implanting a disk-shaped sensor, the implantation tool comprising:
jaws configured to clamp the sensor, which has been wrapped up into a cylindrical shape, and to keep the sensor wrapped up in the cylindrical shape;
a spring configured to keep the jaws clamped together via tension of the spring;
an actuator configured to release the tension of the spring and release the sensor from the jaws.
11 . The implantation tool of claim 10 , further comprising first and second gripping portions configured to grip the sensor when clamped by the jaws.
12 . A subcutaneous implantation tool for implanting a disk-shaped sensor, the implantation tool comprising:
a first rod configured for insertion into a first channel in the sensor;
a second rod configured for insertion into a second channel in the sensor; and
an actuator configured to spread apart the first and second rods apart such that the sensor, which has the first and second ends connected to the first and second rods, respectively, is unwrapped.
13 . The implantation tool of claim 12 , wherein the first and second rods are configured to be removed from the first and second channels, respectively, of the sensor after being spread apart.
14 . The implantation tool of claim 12 , wherein the first channel is at a first end of the sensor, and the second channel is at a second end of the sensor.
15 . The implantation tool of claim 12 , wherein the first and second channels are tapered.
16 . A subcutaneous tunneling tool for implanting a disk-shaped sensor, the tunneling tool comprising:
a handle;
a rod extending from the handle, wherein the rod includes a flat and wide tip at the end of the rod.
