摘要:
Exemplary systems and methods are directed toward the creation of packets of light. A packet contains one or more pulses of light. In some embodiments, the packet may contain two, ten, 100, 1000, 1E6, or more pulses of light. The packet may be characterized by many of the same properties that are used to describe pulses, such as packet energy, packet width, packet power, packet period (for a periodic series of packets), and peak power of the packet. Packets may also be characterized by other properties describing their shapes. These properties may be described or defined by mathematical functions when the packets have complicated shapes.
摘要:
The present disclosure relates to methods for visualizing the opening of a drug reservoir of an implantable medical device. In particular, the present disclosure provides methods for observing the release or exposure of contents from a drug reservoir of a medical device placed within the vitreous of an eye of a subject. The methods include implanting a drug delivery device within an anatomy of a subject. The drug device includes a plurality of reservoirs, each loaded with a therapeutic agent and a marker. Furthermore, the drug delivery device comprises a plurality of barrier layers for separating the contents of one of the plurality of reservoirs from the anatomy. The method further includes irradiating at least one of the plurality of barrier layers such that at least one of the plurality of reservoirs is breached, thereby triggering release of the therapeutic agent and the marker from the device. By visually detecting release of the marker into the anatomy, release of the therapeutic agent into the anatomy is verified.
摘要:
One embodiment of an ultrasound system for reducing the appearance of cellulite includes an ultrasound contact plate positioned within the cavity of a handpiece. Suction is used to draw tissue into the cavity, bringing the skin surface into contact with the ultrasound contact plate during ultrasound energy delivery. A motor mechanically vibrates the handpiece during ultrasound delivery, causing the contact plate to reciprocate relative to the underlying tissue undergoing ultrasound exposure.
摘要:
An implantable drug delivery device that uses multiple reservoir elements to contain and release doses of active pharmaceutical ingredients. The device includes a first shell element, which has a first enclosed cavity volume and forms a low-permeability barrier. The first shell element is configured to absorb light irradiation from a laser source, the laser irradiation causing a breach in the first shell element. A first active pharmaceutical ingredient is contained in the first enclosed cavity volume and is released when the first shell element is breached. The device also includes a second shell element, which has a second enclosed cavity volume and also forms a low-permeability barrier. A second active pharmaceutical ingredient is contained in the second enclosed cavity volume. The device also includes an envelope element containing the first and second shell elements.
摘要:
In a method for removing hair using ultrasound, one or more pulses of ultrasound energy are applied to the tissue at a frequency (e.g. 5-15 MHz) selected to deliver the energy a tissue depths corresponding to those at which hair follicles are located. Pulse widths are selected to correspond to thermal relaxation times for hair. The skin may be optionally cooled before, during, and/or after ultrasound exposure.
摘要:
A system and method for modifying a characteristic of a contact lens is presented. A beam of ultra-short pulses is generated. The beam of ultra-short pulses is delivered to a desired location at the contact lens. A characteristic of the contact lens is modified at the desired location using the beam of ultra-short pulses.
