Abstract: Apparatus and method for delivering and deploying an intravascular device into the vessel including an outer and inner tube that are axially linked by a housing structure at the proximal end of the catheter, and a retractable sleeve structure having a middle tube and sleeve tip. The sleeve tip is sealed to the inner tube at the distal end, and continuously extends into the middle tube. At the proximal end of the sleeve structure, the middle tube is sealed to either a housing structure or slideable proximal ring, forming a sealed chamber between the inner tube and the sleeve structure. A radial space is formed between the sleeve tip and the inner tube optimized for intravascular device placement. During retraction of the sleeve structure, the fold of the sleeve tip peels away from the device, which expands to its deployed state while minimizing axial forces and friction.

Abstract: Devices and methods for tissue and graft procedures are provided that are designed to fail under a certain amount of force, providing sensory feedback that a particular activity may be providing too much stress on a surgical implant. For example, a surgical implant can include a sacrificial element in the form of a filament designed to break when a certain threshold value of force is met or exceeded, while a second filament that has the ability to withstand higher values of force, is able to maintain the repair after the first filament fails. In other embodiments, the sacrificial element includes a filament engagement mechanism associated with a suture anchor configured to fail at a threshold value of force, and a second filament engagement mechanism of the anchor can maintain the repair after the first one fails. Many implants configurations are provided, as are various surgical methods incorporating sacrificial elements.

Abstract: The wax warmer with automated stirring combines the heating element and wax temperature control with a rotating wax reservoir. The rotating wax reservoir causes the associated stored wax to rotate with respect to the body of the device. To interrupt the flow of the wax within the rotating reservoir, and cause mixing and stirring, a stationary stir stick is placed in the path of rotation. As the moving wax contacts the stationary stir stick, turbulence is caused, resulting in mixing. The mixing helps to maintain a consistent temperature of wax within the reservoir. The stir stick is preferably held in position by a slot within the lid, removal of the lid causing removal of the stir stick, removing the stir stick as an obstacle to the user accessing the wax within the vessel.
