A system for the surface and subsurface delivery of therapeutic and cosmetic agents. The system includes a disposable attachable tip with pre-filled medications or cosmetics that is adjustable hand pieces including electromagnetic and mechanical energy delivery devices.

Techniques, devices and systems are disclosed for implementing acoustically triggered propulsion of nano- and micro-scale structures. In one aspect, an ultrasound responsive propulsion device includes a tube that includes one or more layers including an inner layer having an electrostatic surface, and an ultrasound-responsive substance coupled to the inner layer and configured to form gaseous bubbles in a fluid in response to an ultrasound pulse, in which the bubbles exit the tube to propel the tube to move in the fluid.

The devices, assemblies, and methods described herein utilize photoacoustic principals to create a jet of fluid using a ultrasonic resonance member and a pulsed laser light beam. The ultrasonic resonance member is a treated substrate having an liquid interface surface in contact with a fluid. When a pulsed laser light beam is applied to the treated substrate, pressure is generated via induced ultrasonic waves to urge the fluid into a jet stream.

Ultrasound catheter devices and methods provide enhanced disruption of blood vessel obstructions. Generally, an ultrasound catheter includes an elongate flexible catheter body with one or more lumens. An ultrasound transmission member or wire extends longitudinally through the catheter body lumen and, in many embodiments, a guide wire tube also extends through the same lumen. A distal head is fixed to or otherwise mechanically coupled with the distal end of the ultrasound transmission member or wire and is positioned adjacent the distal end of the catheter body. Although the distal end of the catheter body overlaps the distal head, the distal head is not directly affixed to the distal end of the catheter body. Thus, the distal tip may move freely, relative to the distal end of the catheter body when ultrasonic energy is applied through the ultrasound transmission member. Such a freely floating distal head enhances the efficiency of an ultrasound catheter, enabling the catheter to ablate calcific occlusions and increasing the useful life of the ultrasound transmission member and catheter.

A wound drainage and hemostasis promoting medical device (1) are disclosed. A balloon (15) is temporary inflated and arranged outside a sheath (10), in contact with tissue surrounding a wound cavity for hemostasis promotion. The drainage device comprises a fluid communication channel for wound exudate from wound. The balloon is deflated and retracted into said sheath for removal from said wound cavity. Thus the medical device is percutaneously retractable from said confined wound.

A method for preventing and/or ameliorating skin aging in a subject includes administering to the subject in need of such treatments a synthetic peptide, which has an amino acid sequence that has 20-39 amino acid residues. The synthetic peptide has at least 20 consecutive residues that has at least 90% amino acid sequence identity to residues 11-30 of SEQ ID NO: 1.

A method of changing the volume of an intra-bilayer membrane space of at least one bilayer membranous structure of a target tissue. The method comprises providing at least one characteristic of a target tissue having at least one bilayer membranous structure, selecting an acoustic energy transmission pattern set to change a volume of an intra-bilayer membrane space of a bilayer membrane of the at least one bilayer membranous structure according to the at least one characteristic, and applying acoustic energy on the target tissue according to the selected acoustic energy transmission pattern.
