A device for penetrating tissue with reduced force and placing a guidewire is provided. The device includes a driving actuator generating reciprocating motion. A penetrating member having a lumen dimensioned to accommodate a guidewire is provided. A coupler mechanically connects the driving actuator and the penetrating member to transfer the reciprocating motion to the penetrating member. The penetrating member may be coaxial or axially offset from the driving actuator. 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 may also be provided including a channel also dimensioned to accommodate the guidewire, and may further include the frictional member(s) for facilitating movement of the guidewire. The channel and lumen are aligned to permit placement of the guidewire at the target site.

A device for guidewire placement, comprising: an electrically activated driving actuator configured to generate repetitive reciprocating motion in an axial direction along a driving axis sufficient to reduce the force needed to penetrate living being tissue when said driving actuator is activated;a penetrating member having an open distal end and an opposite open proximal end and a lumen extending there between, said lumen dimensioned to accommodate a guidewire, said penetrating member and said lumen extending axially along a penetrating axis spaced apart from said driving axis;at least one coupler in mechanical communication between said driving actuator and said penetrating member, and transmitting said repetitive reciprocating motion from said driving axis to said penetrating member and moving said penetrating member with said repetitive reciprocating motion along said penetrating axis; andat least one frictional member configured to selectively engage and facilitate movement of said guidewire through said lumen. 17. The device as recited in claim 16, wherein said penetrating axis is parallel to said driving axis. 18. The device as recited in claim 16, wherein said coupler rigidly interconnects said penetrating member and said driving actuator to transfer said repetitive reciprocating motion from said driving axis to said penetrating axis. 19. The device as recited in claim 16, further comprising a guidewire actuator that mechanizes movement of said at least one frictional member. 20. The device as recited in claim 19, wherein said guidewire actuator is a motor. 21. The device as recited in claim 16, wherein said at least one frictional member is moved manually. 22. The device as recited in claim 16, wherein said at least one frictional member rotates to move said guidewire in said lumen. 23. The device as recited in claim 16, further comprising a plurality of frictional members, wherein at least one of said frictional members is active. 24. The device as recited in claim 23, wherein at least one of said frictional members is passive and moves dependent on the movement of said at least one active frictional member. 25.
