Abstract

A medical device containing a sensor, a motor, one or more plates, and a control unit, for treating diabetes. The medical device vibrates the pancreas thereby improving blood and secretory hormone circulation and enhancing the production of insulin.

First claim

The invention claimed is:

1. A medical device, comprising:
a glucose sensor;
a single vibration motor, wherein the vibration motor is an ultrasonic transducer configured to vibrate at 40-60 kHz, wherein the plate has a single inner surface and a single outer surface;
a single plate, wherein the plate is connected to the motor through a rod having first and second circular faces, wherein the first circular face of the rod is in direct contact with the vibration motor and the second circular face is in direct contact with the plate, and the plate and motor are implantable in a patient;
a control unit in communication with the motor and the glucose sensor,
wherein the plate is configured to conform to a surface of a pancreas of the patient and the entire inner surface of the plate has a microstructured surface that is configured to be in continuous contact with the surface of the pancreas of the patient, wherein the plate has a continuous curve structure configured to conform with a shape of the pancreas so that an apex of the curve structure is configured to cover a head portion of the pancreas and a chord of the curve corresponds with a tail portion of the pancreas, wherein the vibration motor is connected to the plate at the apex of the curve structure and the plate has a longitudinal axis configured to be parallel to a longitudinal axis of the pancreas;
wherein the plate is configured to be between the vibration motor and the surface of the pancreas and the entire inner surface of the plate is configured to be in contact with the surface of the pancreas,
wherein the microstructured surface has a pattern of repeating microstructure protrusions having an average height of 0.02-2 mm and an average distance between each microstructure protrusion and an adjacent microstructure protrusion is in a range of 5-100 μm, and
wherein the plate has a length in a range of 15-50 mm, a width in a range of 1-25 mm and a thickness in a range of 0.1-2 mm.

2. The medical device of claim 1 , wherein the plate is flexible.

3. The medical device of claim 1 , wherein the plate comprises silicone.

4. The medical device of claim 1 , wherein the control unit comprises:
a display;
at least one battery; and
a central processing unit electrically connected to the vibration motor and the glucose sensor.

5. The medical device of claim 1 , wherein the control unit is configured to actuate and deactuate the vibration motor based on a blood glucose level feedback from the glucose sensor, thereby keeping a blood glucose level within a range of 70-140 mg/dl.

6. The medical device of claim 1 , wherein the microstructure protrusions are made of or coated with one or more selected from the group consisting of alginate, hyaluronic acid and collagen.

7. The medical device of claim 1 , wherein the chord of the curve is in a range of from 0.2-3 mm.
