Abstract
A device for penetrating tissue with reduced force and placing a guidewire is provided. The device includes a driving actuator generating reciprocating motion at less than 20 kHz. A penetrating member having a lumen dimensioned to accommodate a guidewire is provided, and may be coaxial or axially offset from the driving actuator. A coupler mechanically connects the driving actuator and the penetrating member, transferring the reciprocating motion to the penetrating member. At least one frictional member facilitates the movement of the guidewire through the lumen for placement at the target tissue. The frictional member(s) may be operated manually or by a guidewire actuator. A housing including a channel also dimensioned to accommodate the guidewire may also be provided, and may further include the frictional member(s) for facilitating movement of the guidewire. A side port may also be included at the penetrating member or coupler for introduction of the guidewire.
