An implantable dialysis access port assembly for connection of a dialysis machine to a patient and detoxifying blood within the patient. The implantable dialysis access port assembly includes a first port including a first device for receiving a first needle of the dialysis machine, and a first connector and a second port including a second devices for receiving a second needle of the dialysis machine, and a second connector. A first catheter is connected to extend from the first connector and into a vein of the patient and a second catheter is connected to extend from the second connector and into the vein of the patient. The first and second ports are of different geometrical shapes and are readily detectable in position below the skin of the patient such that when the first needle is received by the first receiving device, the second needle is received by the second receiving device and the dialysis machine is turned on, blood is caused to be removed from the vein through the first catheter, the first port and the first needle for detoxification in the dialysis machine and returned to the vein through the second needle, the second port and the second catheter.

A catheter cleaning device for clearing a catheter of obstructions. The catheter cleaning device includes an elongate hollow housing including first and second slots extending along opposing sides thereof and first and second lateral slots extending perpendicular to a respective one of the first and second slots, a guide member encircling the housing and including a bar extending across a diameter thereof and through both the first and second slots, a guide wire extending from the bar and an adapter for connecting the device to the catheter. The adapter includes a recess extending therethrough for the guide wire to pass out of the housing and into the catheter. The first and second lateral slots allow for rotation of the guide member and thus turning of the guide wire. Turning of the guide wire causes the guide wire to scrape against the obstruction thereby breaking the obstruction into smaller pieces and clearing the catheter. The guide wire has a length substantially equal to a length of the catheter and an end of said guide wire is able to bow upon contacting the obstruction.

A system for protecting the appendage of a user from contamination and water seepage while bathing or outdoors during inclement weather. The system includes a protective cover and a sleeve. The protective cover is sized and configured for placement about the hand and arm or the foot and leg of a user. The cover includes a slit with a zipper closure and may include a closure flap at the upper end of the slit. The cover may include securing straps for retaining the cover securely about the appendage of the user. The sleeve extends over and covers the open end of the cover to provide an additional barrier against contamination and seepage.

A power generation system utilizes a wind driven turbine to energize a pair of generator disposed on opposing ends of drive shaft having helical propeller fin attached thereto. The units may be installed on the roof a structure in parapet fashion and stacked to increase power output. Furthermore, the wind driven turbine could be incorporated into a ram air drive to recharge the battery of an electric or hybrid vehicle.

A stent assembly (10) for placement in a body lumen (12) acting to retain the body lumen (12) in an open position. The stent assembly (10) includes a cylindrical shell (14) and a plurality of circular coils (16) embedded within the cylindrical shell (14). The stent assembly (14) is changeable between a first unexpanded state for placement within the body lumen (12) and a second expanded state for holding the body lumen (12) open once positioned therein. The cylindrical shell (14) is made of expandable PTFE material and the plurality of coils (16) are formed of cut rings, the cuts in each coil being staggered about the 360 degree radius of the cylindrical shell (14) providing full support for the cylindrical shell (14) throughout its circumference. The cylindrical shell (14) may also include ridges (24) extending from an outer wall (30) thereof for engaging the inner wall (28) and holding the stent assembly (10) in place. This stent assembly (10) is particularly useful as a venous stent due to its physical characteristics.
