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 Iso 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.
Claims (20)
1. A device for guidewire placement, comprising: an electrically activated driving actuator configured to generate repetitive reciprocating motion at a frequency less than 20 kHz in an axial direction 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 further comprising a lumen extending between said open distal and proximal ends and dimensioned to accommodate a guidewire; at least one coupler in mechanical communication connecting said driving actuator and said penetrating member and transmitting said repetitive reciprocating motion to said penetrating member to cause said penetrating member to move with said repetitive reciprocating motion at a frequency less than 20 kHz in said axial direction during penetration; and at least one frictional member to selectively engage and facilitate movement of said guidewire through said lumen.
2. The device as recited in claim 1, further comprising a guidewire actuator that mechanizes movement of said at least one frictional member.
3. The device as recited in claim 2, wherein said guidewire actuator is a motor.
4. The device as recited in claim 1, wherein said at least one frictional member is moved manually.
5. The device as recited in claim 1, wherein said at least one frictional member rotates to move said guidewire in said lumen.
6. The device as recited in claim 1, further comprising a plurality of frictional members, wherein at least one of said frictional members is active.
7, The device as recited in claim 1, wherein said penetrating member is selectively attached to said coupler,
8, The device as recited in claim 7, wherein said penetrating member is disposable,
9, The device as recited in claim 1, further comprising a housing having a channel extending through at least a portion of said housing, said channel dimensioned to accommodate said guidewire and is in fluidic communication with said lumen of said penetrating member,
10, The device as recited in claim 9, wherein said housing further comprises a housing aperture permitting access to said at least one frictional member.
11 The device as recited in claim 1, wherein said penetrating member extends axially along a penetrating axis, said driving actuator is configured to generate repetitive reciprocating motion along a driving axis, and wherein said penetrating axis is coaxial with said driving axis,
12, The device as recited in claim 12, further comprising a housing including said driving actuator, said at least one frictional member, and a channel dimensioned to accommodate said guidewire extending through at least a portion of said housing and through said driving actuator, such that said lumen of said penetrating member and said channel align in fluidic engagement and form a continuous bore.
13, The device as recited in claim 1, further comprising a side port in fluid communication with said lumen of said penetrating member, said side port dimensioned to accommodate said guidewire.
14, The device as recited in claim 1, wherein said driving actuator comprises at least one of a voice coil, piezoelectric element, and a flextensional transducer.
15. A device for penetrating tissue, comprising: an electrically activated driving actuator configured to generate reciprocating motion in an axial direction 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 further comprising a lumen extending between said open distal and proximal ends and dimensioned to accommodate a guidewire; at least one coupler In mechanical communication connecting said driving actuator and said penetrating member and transmitting said reciprocating motion to said penetrating member; a side port in fluid communication with said lumen of said penetrating member, said side port dimensioned to accommodate said guidewire; and at least one frictional member to engage said guidewire and facilitate movement of said guidewire through said lumen.
16. The device as recited in claim 15, wherein said side port is located at one of said penetrating member and said at least one coupler.
17. The device as recited in claim 16, wherein said penetrating member includes a hub at said proximal end, said side port located at said hub.
18. The device as recited in claim 17, wherein said penetrating member, said hub and said side port are disposable.
19. The device as recited in claim 17, further comprising a housing, said hub selectively attachable to said housing.
20. The device as recited in claim 15, wherein said side port extends from said device at an oblique angle relative to said penetrating member.
