20090287194 | DEVICE FOR IRRADIATING AN INTERNAL BODY SURFACE - The invention provides a device and method for illuminating a body surface. A light source is optically coupled to the proximal end of a light guide and a light scatterer is optically coupled to the distal end of the light guide. The device includes a deployment mechanism that is configured to bring the light scatterer from a small caliber configuration in which the light scatterer is delivered to the body surface to a large caliber configuration in which the light scatterer irradiates the body surface. The invention may be used, for example, irradiate the periadventitial surface of an aneurysmal blood vessel. | 11-19-2009 |
20100063489 | EQUIPMENT FOR TREATING WOUNDS AND METHOD FOR THE BIOCHEMICAL ACTIVATION OF HEALING - This invention concerns a system for dermatological treatment including an energy source suitable for biochemically activating healing and including at least one means of interaction between the energy source and the patient. The means of interaction is composed of a continuous adhesive support suitable for placement close to the area to be treated, the support having a means of identification and interacting without contact with a sensor allowing the energy source to function only when the distance between the sensor and the means of identification is less than a threshold value. The invention also concerns such a continuous adhesive support and a method of dermatological treatment. | 03-11-2010 |
20100249763 | Laser Tissue Fusion of Septal Membranes - A laser tissue fusion device is optimized for particular surgical applications to join tissue layers. The device has two opposed arms that engage and disengage to clamp and release layers of tissue therebetween. The distal end of the first arm is disposed opposite the distal end of the second arm. A laser energy source generates therapeutic laser energy is either integrated within the device is a separate unit. An energy pathway transmits the laser energy to the distal end of the first arm to deliver the laser energy to tissue layers clamped between the distal ends of the arms. An actuator decreases the separation distance between the distal ends of the arms to clamp the tissue layers and activates the laser energy source upon engagement. The laser energy source delivers a burst of energy at a predetermined wavelength for a predetermined period of time sufficient to spot weld the tissue. | 09-30-2010 |
20110130747 | Contact free and perforation safe endoluminal laser treatment device and method - A device and method for endovascular radiation therapy that prevents unwanted damage to blood vessels during treatment is described. One feature is a means for preventing the emission end of an energy delivery device from coming into contact with the wall of a blood vessel. This positioning means may be a distancing catheter or ring incorporated into a catheter. Another feature is a sensing means that senses the inputted radiation power and prevents irradiation above a preselected power or energy level. Both features serve to prevent radiation, having an overly high intensity or power density, from impacting the vessel wall and causing a puncture. | 06-02-2011 |
20130131655 | BREAST RECONSTRUCTION OR AUGMENTATION USING COMPUTER-MODELED DEPOSITION OF PROCESSED ADIPOSE TISSUE - A tissue transfer method for reconstruction and augmentation of soft tissue. The method includes harvesting adipose tissue from a patient. The harvested tissue is processed via centrifugation to isolate a purified subset of the adipose tissue including separating and removing a substantial amount of triglycerides from the harvested adipose tissue. The centrifugation may be performed to cause separation of water from the purified adipose tissue and to cause separation of oil from mature adipocytes. Specifically, the spin rates may be selected to be high enough to cause lesions in the mature adipocytes that results in the release of the oil. The method continues with implanting the purified adipose tissue into the patient at a breast or other area identified for reconstruction or augmentation. The implanting is performed based on an injection pathway model that defines injection point locations and a number of injection pathway directions from each point. | 05-23-2013 |
20140066910 | MEDICAL DEVICES AND METHODS INCORPORATING FRUSTRATED TOTAL INTERNAL REFLECTION FOR ENERGY-EFFICIENT SEALING AND CUTTING OF TISSUE USING LIGHT ENERGY - A medical instrument includes two jaw members, at least one of which creates conditions of frustrated total internal reflection at a tissue-contacting surface when tissue is grasped between the two jaw members. The first jaw member may include an optical element having a tissue-contacting surface. The medical instrument also includes a light source that provides a light beam for sealing tissue. The light source is positioned so that the light beam is totally internally reflected from an interface between the tissue-contacting surface and air when tissue is not grasped by the jaw members. When tissue is grasped by the jaw members, at least a portion of the light beam is transmitted through that portion of the tissue-contacting surface that is in contact with the tissue. The light source may be movably coupled to a jaw member to scan the light beam and/or to change the incident angle based on optical properties of the tissue. | 03-06-2014 |
