Abstract
A medical device includes a needle and optionally a catheter and a sheath. The device takes a biopsy from a body tissue and/or injects a substance into a body tissue, such as heart tissue. One or more ports are located on the needle to either take a biopsy and/or inject a substance. If a catheter is included as part of the device, a relative motion restrictor may be included to restrict relative movement during needle deployment between the catheter and the sheath. Additionally, a driver may be employed to deploy the needle with one or more of a predefined force, acceleration and velocity to assist in needle penetration.
