An apparatus and methods for tissue restoration are provided. The apparatus may include a catheter shaft extending from a proximal end to a distal tip, the catheter shaft defining lumens including an inflation lumen and a light fiber lumen, a coated balloon positioned on a translucent distal segment of the catheter shaft proximal to the distal tip in fluid communication with the inflation lumen, the coated distal balloon comprising a translucent material and a coated material on an outer surface of the coated balloon, and a light fiber positioned in the catheter shaft in the light fiber lumen and extending through the translucent distal segment.

A portable hair removal device (10), comprising a head portion (30), and a housing (20) connected to one end of the head portion (30). An emitter capable of emitting light is provided in the housing (20), and the light emitted by the emitter passes through the head portion (30) and then acts on the skin for hair removal. The head portion (30) is provided with at least a phototherapy lamp (32), and light emitted by the phototherapy lamp (32) acts on the skin through the head (30) and takes care of the skin. The portable hair removal device (10) has rich functions and a good skin care effect.

A system for controlling operation of a radiofrequency treatment device to apply radiofrequency energy to tissue to heat tissue to create lesions without ablating the tissue. The system includes a first treatment device having at least one electrode for applying radiofrequency energy to tissue, a controller including a connector to which a first treatment device is coupled for use, and a generator for applying radiofrequency energy to the electrodes. The controller controls application of energy so that the tissue is thermally treated to create lesions but preventing thermal treatment beyond a threshold which would ablate the tissue.

A surgical instrument includes a housing including an actuator disposed thereon and an elongated shaft extending therefrom. The elongated shaft includes an end effector assembly including a pair of opposing jaw members including a knife channel defined therein. An articulation section is disposed between the housing and the end effector assembly and is configured to articulate the end effector assembly upon actuation of the actuator, the articulating section and a proximal end of the knife channel defining a first distance therebetween. A knife assembly includes a knife having a length, the proximal end including an engagement feature disposed thereon. A knife drive rod is configured to engage the engagement feature to secure the knife drive rod to the knife such that the distal end of the knife extends beyond the engagement feature and wherein the knife length is less than the length of the first distance.

A knife assembly for use with a surgical instrument includes a knife having proximal and distal ends, the proximal end including an aperture defined therein having a series of spaced apart fins extending thereacross. A knife drive rod is included and is configured to operably engage the fins to secure the knife drive rod to the knife. A retention mechanism is operably disposed at a distal end of the knife drive rod and is configured to secure the knife drive rod in engagement between the fins.

This disclosure relates generally to medical devices, systems, and methods for activation of a photoactive agent during a medical procedure. In an aspect, a catheter system for activation of a photoactive agent may comprise a catheter comprising an elongate shaft comprising a proximal portion, a distal portion, and a first lumen extending along the elongate shaft. A first flexible circuit may be disposed about the distal portion of the elongate shaft. A plurality of first light-emitting diodes (LEDs) may be disposed along the first flexible circuit. A second flexible circuit may be disposed about the distal portion of the elongate shaft. A plurality of second LEDs may be disposed along the second flexible circuit. A control unit may be coupled to the proximal end of the elongate shaft. The communications cable may be disposed within the catheter and may electrically couple the first LEDs with the control unit.

The disclosure relates to a device and a method for the treatment of diseases of the skin, glands, mucousae, connective tissue, nerves and/or horny tissue. The device is adapted for the treatment of diseases of the skin, glands, mucousae, connective tissue, nerves and/or horny tissue and has at least one applicator, which applicator is arranged outside the device housing; at least one radio wave module, which radio wave module is adapted to generate an adjustable electromagnetic radiation with a variable frequency or with at least one constant frequency with an adjustable variable or at least one adjustable constant intensity.

A light applicator (5) for examining and/or treating an organic body includes a minimal-invasive, rigid, semi-flexible or flexible insertion section (11) which extends along a longitudinal direction (L) and at its distal end includes an LED (19). The light applicator (5) includes a first electrical lead (61a) for the supply of electricity to the LED (19). The lead extends in the insertion section (11) in the longitudinal direction (L) and there has a cross-sectional area of at least 70% of the cross-sectional area of the light applicator (5). The light applicator (5) in the insertion section (11) is thermally insulated in the radial direction in a manner such that the radial thermal insulation reduces proximally.
