Abstract: An abrasive tip is used to exfoliate skin and tissue through abrasive materials integrated in the tip. The tip also delivers fluid to the skin and vacuums the fluid and abraded tissue during treatment. In an implementation, the tip is replaceable and disposable.

Abstract: A cannula insertion device for use with an insertion set includes an insertion module and a cannula insertion needle. The insertion module has a housing (with a housing distal end, a housing proximal end, and a housing opening extending from the distal to the proximal end) and a plunger that is disposed within the housing opening. The plunger has a plunger distal and proximal ends. The cannula insertion needle is attached to the plunger distal end. In addition, the plunger distal end is configured to releasably retain a cannula cartridge of the infusion set in operative alignment with the cannula insertion needle and the housing distal end is configured to releasably retain an infuser base of the infusion set in operative alignment with the cannula cartridge.

Abstract: A method for mounting an infusion set to an infusion site includes adhering an infuser base of the insertion set to an infusion site on a user's skin and inserting a cannula cartridge of the infusion set into an opening of the infuser base such that a cannula of the cannula cartridge is subcutaneously inserted into the infusion site. Subsequently, the method includes removeably attaching a hub of the infusion set to a barb of the infuser base such that a hub needle of the hub pierces a self-sealing septum of the cannula cartridge, thereby creating a fluid pathway from the hub needle to the cannula. In the method, the attachment of the hub to the barb is such that user-controlled three-hundred and sixty (360°) rotatable motion between the hub and the barb is provided.

Abstract: An infusion set includes an infuser base, a cannula cartridge and a hub. The infuser base includes an adhesive pad configured for removably adhering the infuser base to an infusion site, a barb, and an infuser base opening. The cannula cartridge includes a cannula for subcutaneous insertion into the infusion site and a cannula cartridge self-sealing septum. The hub is configured for removable and user-controlled three hundred and sixty degree (360°) rotateable engagement with the barb. The hub includes a hub needle for piercing the self-sealing septum, thereby creating a fluid pathway from the hub needle to the cannula of the cannula cartridge. The hub also includes a flexible tube in fluid communication with the hub needle. The cannula cartridge of is configured for insertion into the infuser base opening with the cannula being subcutaneously inserted into the infusion site.

The hub is configured for removable and user-controlled three hundred and sixty degree (360°) rotateable engagement with the barb. The hub includes a hub needle for piercing the self-sealing septum, thereby creating a fluid pathway from the hub needle to the cannula of the cannula cartridge, and a hub self-sealing septum. The cannula cartridge is configured for insertion into the infuser base opening with the cannula being subcutaneously inserted into the infusion site.

Abstract: A method for inserting a cannula of an infusion set into an infusion site includes releasably retaining a cannula cartridge of an infusion set on a distal end of a cannula insertion device plunger. The method also includes releasably retaining an infuser base on a distal end of a housing of the cannula insertion device. Subsequently, the method involves moving the plunger from a retracted position, wherein the cannula cartridge is remote from the infuser base, to an advanced position wherein the cannula cartridge is engaged with the infuser base and a cannula of the cannula cartridge has been subcutaneously inserted into an infusion site by a cannula insertion needle attached to the plunger.

Abstract: An infusion set is disclosed. The infusion set includes a cannula hub assembly having a cannula housing body with a distal end and a bottom surface. The set includes an insertion needle assembly having an elongated insertion needle hub adapted to be coupled to the cannula housing body and a cannula having a distal cannula end. The cannula is at least partially slidably disposed within the insertion needle hub. The insertion needle assembly also includes an insertion needle having a distal insertion needle end, wherein the needle extends coaxially through the cannula. The distal cannula end and the distal insertion needle end are adapted to be inserted through the distal end of the cannula housing body. The insertion needle is retractable from the cannula housing body to be at least substantially disposed within the insertion needle hub. A method of inserting the cannula through a patient's skin is also disclosed.

Abstract: An infusion set for administration of fluid to a subcutaneous layer includes a cannula housing adapted for mounting onto a patient's skin and a needle housing for connection to the cannula housing. The needle housing has a pair of flexible sidewalls and a resilient band connected to the sidewalls. The resilient band is lockably engageable with the cannula housing to thereby secure the housings together, and is releasable from the cannula housing when the sidewalls are pressed toward each other to deform the resilient band. A hollow needle extends out of a main body of the needle housing for delivering fluid to the cannula from a fluid source. The walls of the needle housing extend beyond a distal end of the hollow needle to prevent needle contact with contaminated surfaces and inadvertent injury.

Abstract: A laser scanning method and apparatus having a scanning hand piece 18 connected at the free end 20 of a hollow wave guide 14 to scan a beam of laser energy 22 in a predetermined pattern to uniformly ablate in an enlarged target area. The hand piece 18 includes a hollow shaft motor 40 having a conduit mounted therein for conducting the beam of laser energy 22. The conduit 54 has a proximal end 56 in axial alignment with the longitudinal axis 60 of the hollow shaft 48 and in light energy communication with the laser energy generator 12. The distal end 58 of the conduit 54 is mounted in the hollow shaft 48 so that it is eccentrically positioned with respect to the axis 60 of the hollow shaft 48. When the motor 40 is energized, the hollow shaft 48 rotates the distal end 58 of the conduit 54 in a predetermined circular pattern to scan the laser energy uniformly and thoroughly over the tissue in the target area.

Abstract: A gas laser having a housing including a discharge region that contains a lasing gas medium, a pair of DC electrodes having primary surfaces facing toward the discharge region, the primary surfaces being arranged in substantially parallel planes, and a pair of RF electrodes having secondary surfaces facing toward the discharge region, the secondary surfaces being in substantially parallel planes with the secondary surfaces being arranged substantially orthogonal to the primary surfaces. The gas laser also has an RF power source connected between said pair of RF electrodes and selectively generating an RF discharge in the discharge region, and a DC power source connected between said pair of DC electrodes and selectively generating a DC discharge in the discharge region.

Abstract: A medical laser delivery system usable to transmit laser energy from a laser energy source to a surgical site of a patient. The delivery system includes a handpiece adapted for rotatable coupling to a delivery arm coupled to the laser energy source such that the handpiece is rotatable about its longitudinal axis with respect to the delivery arm. A distal delivery system is coupled to the handpiece and delivers laser energy to the surgical site when the laser energy source is actuated. The handpiece includes a handpiece body adapted for rotatable coupling to the delivery arm and a handpiece head coupled to both the handpiece body and the distal delivery system. The handpiece head can be rotatably coupled to the handpiece body. In one embodiment, the handpiece head is angularly oriented at a fixed angle with respect to the handpiece body.
