There is a need for a minimally invasive surgical treatment method for periodontitis for the removal of deep pockets, elimination of disease, creation of reattachment of the gingiva to the tooth surface and true regeneration of the attachment apparatus (new cementum, new periodontal ligament, and new alveolar bone) on a previously diseased root surface. The PerioLase? MVP-7? including eGUI or another device capable of laser dosimetry, such as an original MVP-7? type laser without the eGUI, achieves this with the LANAP protocol (laser-assisted new attachment procedure) and the LENAP protocol (laser excisional new attachment procedure).

A laser scanning system for scanning a laser beam of a hair cutting device includes a laser scanning device for generating a scanning movement of the laser beam and a movable optical device for adjusting and/or focusing the laser beam. The laser scanning device includes an arrangement with at least one movable optical element which is mechanically coupled to the movable optical device, and an optical system fixed to the laser scanning device. The movable optical element is arranged to inter-relate a position of the movable optical device to a mobile access-position where the laser beam enters the optical system. Further, the optical system is arranged to inter-relate said mobile access-position to at least one corresponding position where the laser beam is incident on the movable optical device.

A dental laser comprises a hand piece (100) having a grip region (100a) and a treatment tip (101) with an outlet point (101a), arranged at a distal end, for laser light (102), and further comprises a light source (103) and light conduction means (105) for providing laser light (102) at the outlet point (101a). The laser light (102) has a wavelength (104) of 44520 nm, in particular, 44510 nm and more particularly 4455 nm, and an optical power output is provided at the outlet point in a power range of at least 2 W, advantageously at least 3 W and, in particular, 3.5 W. In another dental laser the laser light (102) has a wavelength (104) of 41010 nm, and an optical power output is provided at the outlet point (101a) in a power range of no less than 1 W to no more than 2 W.

Dermatological systems and methods for providing a therapeutic laser treatment using a handpiece delivering one or more therapeutic laser pulses to a target skin area along a first optical path, and sensing the temperature of the target skin area based on infrared energy radiating from the target skin area along a second optical path generally counterdirectional to the first optical path, and sharing a common optical axis with the first optical path for at least a portion of the first and second optical paths. The handpiece may also provide contact cooling for a first skin area comprising the target skin area.

A laser and a minimally invasive dental surgical procedure using the laser to stimulate periodontal tissue formation.

A steerable laser probe may include an actuation structure, a nosecone fixed to the actuation structure by one or more links and one or more link pins, a housing tube having a first housing tube portion with a first stiffness and a second housing tube portion with a second stiffness, and an optic fiber disposed in the housing tube and the actuation structure. A compression of the actuation structure may be configured to gradually curve the housing tube and the optic fiber. A decompression of the actuation structure may be configured to gradually straighten the housing tube and the optic fiber.

A device configured to cut hair using laser light includes a handle portion and a shaving portion. The handle portion includes a battery and a laser light source. The laser light source is coupled to and configured to receive power from the battery. The laser light source is also configured to generate laser light having a wavelength selected to target a predetermined chromophore to effectively cut a hair shaft. The shaving portion includes a support and a single fiber optic supported by the support. The fiber optic has a proximal end, a distal end, an outer wall, and a cutting region positioned towards the distal end and extending along a portion of the side wall. The fiber optic is positioned to receive the laser light from the laser light source at the proximal end, conduct the laser light from the proximal end toward the distal end, and emit the light out of the cutting region and toward hair when the cutting region is brought in contact with the hair.

A medical device for implantation in a hip joint of a patient is provided. The medical device comprises a first and second piece and a releasing member adapted to, in a first state hold the first piece attached to the second piece, and in a second state release the first piece from the second piece. The releasing member is adapted to change from the first state to the second state when a pre-determined strain is placed on the releasing member.
