A vibration assisted needle device is disclosed for use in medical procedures such as needle aspiration biopsies. Reciprocation of the needle, such as a biopsy needle, eases the advance of the needle through tissue, penetration of the site of interest and the collection of sample at a site of interest. The device comprises a housing defining a chamber, a needle support external to the chamber for supporting a needle and a mechanism in the chamber for causing reciprocatory motion of the needle support. The needle support is preferably external to the housing. A syringe support may be connected to the housing for supporting a syringe. The reciprocatory mechanism may comprise means for converting rotational motion into reciprocating motion, such as a bearing or a rotor with a circumferential, angled groove on its surface, coupled to the needle support. The bearing or the rotor may be driven by a rotational motor, preferably located outside of the housing, or by a hydraulically driven turbine within the housing. Alternatively, the reciprocatory mechanism means may comprise a stationary solenoid and a movable solenoid for being coupled to the needle.

An inner sleeve for a flat extrusion cylinder includes an inner sleeve ring piece, an upper insert piece and a lower insert piece. The inner sleeve ring piece is positioned in an intermediate sleeve of the flat extrusion cylinder. The upper insert piece and the lower insert piece are symmetrically disposed on an inner wall of the inner sleeve ring piece to form an inner sleeve working die cavity of the flat extrusion cylinder. Arc surfaces of two insert pieces match with the arc inner wall of the inner sleeve ring piece, so as to improve the stress distribution at interface portions between the flat surface and the arc surface of the inner sleeve working die cavity. When the flat extrusion cylinder is operated, the insert pieces will make a minor displacement in upward and downward direction due to the pressure from the inner sleeve working die cavity, such that the inner sleeve ring piece is elastically deformed in a circumferential direction, thereby generating a resisting force against the peak stress in the cylinder. In the flat extrusion cylinder according to the present invention, concentrated internal stress is uniformly transmitted to the inner sleeve ring piece, which decreases the peak stress in dangerous sections and achieves cylinder-type stress distribution in the flat extrusion cylinder. Thus, the stress received by the inner sleeve ring piece is distributed uniformly, thereby increasing the lifespan of the entire flat extrusion cylinder.

Intravascular delivery system for deployment of a therapeutic device (such as a stent, and / or other therapeutic devices including balloon catheter(s), laser catheter(s), intravascular ultrasound (IVUS), Optical coherence tomography (OCT), drug delivery catheter(s), coil delivery catheter(s), etc.) as required by a particular surgical procedure, in a controlled and robust manner is supported by a lockable balloon catheter equipped with a locking mechanism configured to lock in vivo to a delivery component, such as a guidewire. The lockable balloon catheter can be controllably transitioned between locked and unlocked modes of operation by inflation / deflation of the balloon of the lockable balloon catheter. The system provides an enhanced interlocking interface between the delivery component and an inner shaft by a unique configuration of the inner shaft. Connection of the inner shaft / guidewire and / or outer shaft / inflation lumen to the balloon is by an extended “neck” at the end(s) of the balloon which snuggly envelopes the portions of the inner and / or outer shaft(s) entering / exiting the balloon, thus avoiding the bonding and simplifying fabrication process. Being in the locked mode of operation, the lockable balloon catheter facilitates delivery of the therapeutic device along the delivery component to a target site while enhancing the stability of the delivery component, especially near the target site.
