An automatic insertion device and method of using the same is provided. A vibrator and an extender are connected to a penetrating member and are both in electrical communication with a controller. A detector identifies a subcutaneous target for insertion and the insertion angle, distance and trajectory for the penetrating member are calculated. The vibrator provides vibrations to the penetrating member and the extender advances the penetrating member for insertion. The vibrator and extender are in electrical communication with one another during the insertion process and adjustments to the insertion speed are made based on feedback of vibrational load encountered by the vibrator during insertion, and adjustments to the vibrations are made based on feedback of insertion load encountered by the extender during insertion. Iterative samples are taken to constantly adjust the operation of one motor based on the operations and feedback from the other motor.

Device and method for automated insertion of penetrating member

A device for engaging tissue includes a body disposable around the distal end of a medical instrument, such as an endoscope, and a handpiece. The body includes a primary channel for receiving the medical instrument and at least one arm channel for receiving an arm therethrough. At least one arm extends through the arm channel of the body and proximally to the handpiece. The arm includes an engagement member distally of the body, and may further include a bend between the body and engagement member. The engagement member is movable between a first position not contacting tissue and a second position contacting tissue. With multiple engagement members, the engagement members are farther apart from one another in the first position and closer together in the second position. Movement of the engagement members is controlled by selective and independent movement of the corresponding arms by rotational and/or translational motion.

Device for aiding in the positioning and anchoring of an endoscope during gastrointestinal procedures

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.

Reduced force device for intravascular access and guidewire placement

A device for gripping tissue that is inside of a patient for use in delivering therapy is provided. The device may include a first gear that rotates and that engages the tissue. A second gear that also rotates may be included and may likewise engage the tissue. A spacing mechanism may be included in the device that adjusts the spacing between the first and second gears such that the first and second gears are moved closer to one another and moved farther from one another.

Miniature device platform for navigation on moving organs

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.

The application is directed to piezoelectric single crystals having shear piezoelectric coefficients with enhanced temperature and/or electric field stability. These piezoelectric single crystal may be used, among other things, for vibration sensors as well as low frequency, compact sonar transducers with improved and/or enhanced performance.

Temperature and field stable relaxor-PT piezoelectric single crystals

A transducer is disclosed that includes a multiply resonant composite, the composite having a resonator bar of a piezoelectric single crystal configured in a dtransverse length-extensional resonance mode having a crystallographic orientation set such that the thickness axis is in the &#x3c;110&#x3e; family and resonance direction is the &#x3c;001&#x3e; family.

Transverse mode multi-resonant single crystal transducer

A piezoelectric composite micromachined ultrasound transducer including single and multilayer 1-D and 2-D arrays having through-wafer-vias (TWVs) that significantly decreased electrical impedance per element, and hence the improved electrical impedance matching to T/R electronics and improved signal to noise ratio is disclosed. The TWVs facilitate integrated interconnection in single element transducers (positive and negative contact on the same side) and array transducers (contact pads array for integration with T/R switches and/or pre-amplifier circuits).

Micromachined piezoelectric ultrasound transducer arrays

A tangentially poled piezoelectric single crystal ring resonator is disclosed. A single crystal material is machined into elements and formed into a ring structure. The single crystal elements have a &#x3c;110&#x3e; poled tangential axis. The elements may also have a &#x3c;211&#x3e;, &#x3c;511&#x3e; or &#x3c;322&#x3e; orientation range in the radial direction. The elements may have a generally wedge shape.
