Apparatus, systems, and methods for treating an eye utilizing ab externo pressure wave generation. The shockwave generator comprises a housing comprising a fluid-filled chamber and an eye-contacting surface or chamber configured to contact a surface of the eye. First and second coaxially-aligned electrodes disposed within the housing are configured to generate an electric arc across a gap between the electrode tips when energized and thus produce a shockwave in a fluid of the fluid-filled chamber. The shockwave generator is coupled to the surface of the eye before focusing a shockwave to a pre-determined location on or below the surface of the eye. A plurality of shockwave generators may be disposed within a fluid-filled chamber of a contact lens, which may comprise a contact balloon.

Embodiments of the present disclosure are directed to methods of inducing therapeutic adipose tissue inflammation using high frequency pressure waves (e.g. high frequency shockwaves) wherein the inflammation results in a reduction in the volume of subcutaneous adipose tissue. Embodiments include applying electrohydraulic generated shockwaves at a rate of between 10 Hz and 1000 Hz to reduce the appearance of cellulite or the volume of subcutaneous fat in a treatment area.

A treatment device includes a housing having a longitudinal axis extending between a proximal end and a distal end, a motor, a drive shaft operatively coupled to the motor, a compression spring at least partially disposed about the drive shaft, a helical cam disposed adjacent the compression spring, the helical cam having at least one discontinuity, a hammer coupled to the helical cam and moveable therewith, and a tip disposed adjacent the distal end.

Embodiments of the present disclosure are directed to systems, devices, and methods of inducing physical effects in tissue, such as dermis, adipose, musculoskeletal, vascular, hepatic tissue, using unfocused or planar, non-cavitating acoustic shock waves. The physical effects include disruption of fibrous extracellular matrix of the targeted tissues. Embodiments of the present disclosure include applying rapid acoustic pulses (e.g., shock waves) to cause a breakdown in the fibrous extracellular matrix to reduce the appearance of cellulite or scars in a treatment area. Such unfocused or planar, non-cavitating acoustic shock waves may induce a tissue reaction, such as reduction of fibrosis, induction of angiogenesis, or lymphangiogenesis.

Disclosed is an ultrasonic transducer including a housing, a base disposed on a front surface of the housing, and multiple linear arrays each arranged in a radial direction on the base, extending from a central region of the base, and configured to irradiate a therapeutic ultrasonic wave, the linear arrays each including a plurality of piezoelectric elements which are linear elements extending side by side with each other in the radial direction.

The present disclosure relates to a devices and methods to control suction during medical procedures, and more particularly to medical suction devices, systems, and methods for controlling suction using the portable suction devices/systems during endoscopic procedures. For example, the present disclosure includes a portable suction device in fluid communication with an endoscope system, the portable suction device including: a suction regulator device releasably coupled to and in communication with at least one suction tube of the endoscope system, the at least one suction tube in fluid communication with an endoscope of the endoscope system and a suction source of the endoscope system, wherein the suction regulator device is actuatable to at least one of increase or decrease a suction force within the at least one suction tube.

Systems and methods for detecting and disrupting obstructions (such as clot material) within a blood vessel are disclosed herein. In some examples, the present technology comprises a system for detecting and disrupting a clot in a cerebral blood vessel of a patient, where the system comprises a treatment environment, a detection system, and an energy delivery device. The detection system may be configured to determine the presence of a blood clot within a cerebral blood vessel of a patient. In some embodiments, the detection system is configured to obtain data characterizing a position of the clot within the treatment environment. The energy delivery device can be configured to receive the data characterizing the position of the clot and, based on the data, deliver energy to the clot, thereby disrupting the clot and restoring blood flow in the affected blood vessel.

A method is disclosed for removing a vascular occlusion, such as a clot, from a blood vessel. A tubular sheath is inserted into the vessel and a self-expanding Nitinol mesh filter is deployed from a distal end of the tubular sheath at a location proximal to a clot. An inner catheter is advanced through the tubular sheath and through the mesh filter for contacting the clot. An expandable agitation element is provided along a distal end portion of the inner catheter for cutting or chopping the clot, thereby facilitating removal of the clot and improving blood flow through the vessel. Resulting clot particles are captured by the mesh filter. Negative pressure may be applied along a proximal end portion of the sheath for aspirating remaining particles. Certain embodiments of the method are well-suited for treating deep vein thrombosis and do not require the use of thrombolytic drugs.
