An apparatus includes a transducer assembly including a transducer housing and an ultrasonic transducer disposed within the transducer housing. A transducer horn is disposed at least partially within the transducer housing and includes a probe coupling. A first probe includes a first coupler and a first elongate member coupled to the first coupler. The first coupler has a first coupling portion and a second coupling portion, and the first coupling portion is configured to be releasably coupled to the probe coupling of the transducer horn such that the first probe is coupled to the ultrasonic transducer. A second probe includes a second coupler and a second elongate member coupled to the second coupler. The second coupler has a third coupling portion releasably couplable to the second coupling portion of the first coupler such that the second probe is coupled to the ultrasonic transducer.

Dual ultrasonic catheter and methods of use

A compound transmission member including: a first tube sub-member and a second tube sub-member, each including: a first end having a first opening and a second end having a second opening, wherein the first opening is in fluid communication with the second opening, and wherein at least the first tube sub-member is configured to transmit ultrasonic energy; and a fitting configured to receive the first ends of the tube sub-members.

Device having a multi-channel transmission member

An apparatus includes a generator including a control module that is operably coupled to a power module. The power module is configured to produce an electronic signal to be received by an ultrasonic energy delivery assembly. The ultrasonic energy delivery assembly is characterized by a natural frequency, and the electronic signal is characterized by a frequency. The control module is configured to send a control signal to the power module to randomly vary the frequency of the electronic signal within a range defined at least in part by the natural frequency.

Systems and methods for controlling delivery of ultrasonic energy to a bodily tissue

An apparatus includes a transmission member having a proximal end portion and a distal end portion. The transmission member is configured to be inserted into a bodily lumen, and is configured to transfer ultrasonic energy from the proximal end portion to the distal end portion. The transmission member defines a lumen along a longitudinal center line of the transmission member. The distal end portion of the transmission member includes a concave engagement surface and a distal end surface. The distal end surface defines a plane that intersects the longitudinal center line of the transmission member at an angle of between about 75 degrees and about 105 degrees. The engagement surface is configured to engage a target tissue within the bodily lumen to limit movement of the target tissue along the longitudinal center line. The engagement surface defines an opening in fluid communication with the lumen.

Devices and methods for removing occlusions from a bodily cavity

An apparatus includes a monolithically-constructed transmission member that defines a lumen along a longitudinal axis. The transmission member includes a first portion, a second portion, and a third portion. The first portion is configured to be coupled to an ultrasonic energy source. The second portion is configured to contact a bodily tissue to transfer ultrasonic energy from a first portion into the bodily tissue. The third portion is disposed between the first portion and the second portion and defines a cross-sectional moment of inertia that is less than at least one of a cross-sectional area moment of inertia of the first portion or a cross-sectional moment of inertia of the second portion.

Dual probe with floating inner probe

The present invention relates to a device with an ultrasonic-based probe for drilling and coring. The invention uses ultrasonic and subsonic vibrations produced by a frequency compensation coupler or free mass to produce the hammering action of a partially disengaged probe, with a relatively low axial force required. The invention can also be fitted with irrigation and aspiration capabilities. The invention can furthermore be furnished with a body sensor-feedback apparatus, which provides feedback to the operator as to the optimal frequency and power use of the generator. One embodiment of the invention also has a cooling mechanism to keep the drill or coring apparatus at an optimum temperature.
