ABSTRACT:
A delivery device for insertion of a myocardial implant into a heart wall for trans myocardial revascularization (TMR) of the heart wall. The delivery device provides for the exact placement of one or more TMR implants into a heart wall, and has an elongated, tubular body that may include spaced-apart ports and a connecting conduit. A needle point is formed at one end to pierce the heart wall, and a handle is formed at another end to manipulate the device. The delivery device may include a surrounding sheath into which the needle point and a needle assembly may be withdrawn to release the TMR implant in the heart wall, and withdraw the delivery device from a person's body. The sheath may include a locking portion for holding the TMR implant in position when releasing the implant in a heart wall.
