Abstract: A hand-held, power operated debridement tool (2000) includes a rotary disk knife blade (2300) with a cutting edge (2360) on an outer peripheral edge (2362) of the knife blade, the cutting edge defining a cutting plane (CP) of the disk knife blade. The debridement tool further includes an annular skin guide (2700) including an outer wall (2716) defining a skin contact surface (2720) disposed above the cutting plane (CP) of the disk knife blade and positioned radially inwardly of the disk knife blade cutting edge to receive and direct an excised layer of skin tissue (EST) cut by the disk knife blade upwardly away from the blade cutting edge. The debridement tool additionally includes an axially adjustable depth gauge (2620) including a depth gauge plate (2622) disposed above the cutting plane of the disk knife blade and positioned radially outwardly of the cutting edge of the disk knife blade.

Abstract: A head assembly (200) for a power operated dermatome (100) including a frame body or housing (202) supporting a gear train (520), a blade housing assembly (400), an annular rotary knife blade (300) supported for rotation about an axis of rotation (R) by the blade housing assembly (400). The rotary knife blade (300) includes an inner wall (365) defining an interior region (301) and has a cutting edge (360) at one end (368) defining a cutting plane (CP). The head assembly (200) further includes a depth gauge assembly (600) including a depth gauge support (602) and a depth gauge (620) including a depth gauge plate (622) supported by the depth gauge support (602) for axial movement along the axis of rotation (R), the depth gauge plate (622) extending into the interior region (301) and the depth gauge support (602) attached to and extending from the frame body (202).

Abstract: A totally implantable method for occluding the urethra or bladder neck utilizing an occlusive cuff connected to a control mechanism via a conduit tube. The occlusive cuff is reversibly changed from an activated (occlusive condition) to a de-activated (non-occlusive) condition by depressing a deactivation button contained within a resilient, elastomeric sheath surrounding the control mechanism. The occlusive condition is once again obtained by depressing an activation button also situated within the resilient sheath. In the occlusive condition, a preset tension is applied to a flexible diaphragm through a tensioning suture by a constant force spring contained within the control mechanism. This tension is translated into an occlusive pressure applied to the urethra or bladder neck sufficient to prevent urinary leakage.

Abstract: An implantable vessel occlusive device and method for occluding a vessel are described, for example to occlude the urethra or bladder neck. The devices and methods described utilize an occlusive member connected to a control mechanism. The occlusive member is reversibly changed from a non-occlusive condition to an occlusive condition, for example by depressing an activation button contained within a resilient, elastomeric cover surrounding the control mechanism. In the occlusive position, an initial tension is applied to the occlusive member through a tensioning suture. The tension is translated into an occlusive pressure applied to the urethra or bladder neck that is sufficient to prevent urinary leakage. The non-occlusive position can be obtained by depressing the de-activation button. The occlusive member is constructed to allow elution of drugs, such as may be required to combat infection or tissue encapsulation from its surface.
