Infusion syringe
First Claim
1. A syringe, comprising:
- a barrel;
a plunger positionable within and translatable along a length of the barrel;
a pressure transducer housed at least partially within an interior of the plunger; and
a tip at an end of the plunger, including a pressure translating region positioned over the pressure transducer.

Abstract
A device for applying and measuring fluid pressure in the lumen of a syringe in communication with a tubular member attached to a needle inserted into the body of a disk found in the spinal column of the back. A pressure transducer is integrally mounted in the plunger of the syringe under the plunger tip, such that the force applied by the plunger to the fluid in the syringe is transmitted to the transducer and the resulting electronic signal is converted to a display value aiding the physician in diagnosing diseased disks in the back. Other uses of pressure applying monitoring syringes for other applications in communication with the body also benefit from the disclosed syringe construction, such as percutaneous translumenal angioplasty (PTA) procedures.

11. A method for initializing electronics of a pressure-sensing syringe, comprising:
-
providing power to the electronics;
determining whether an initial pressure monitored by a pressure transducer in communication with the electronics is within a range defined by at least one threshold value; and
reinitializing the electronics if the initial pressure is not within the range. - View Dependent Claims (12, 13)
