A hemodialysis and vascular access system which includes a catheter having an arteriovenous fistula utilizing an indwelling silastic venous end and an arterial end which is adapted to be anastomosed to an artery is described. The catheter includes a needle receiving s through which a needle is inserted to access fluid flow within the hemodialysis and vascular access system. The invention enables use of an “arterialized” indwelling venous catheter where blood flows from an artery through the hemodialysis and vascular access system and is returned to the venous system via an arrangement wherein the outflow opening is distinct and distant from the site where the catheter enters the vein. The site of blood return to the venous system is not directly fixed to the venous wall but is free floating within the venous system. This system provides a hemodialysis and venous access graft which has superior longevity and performance and is relatively easy to implant.

A hemodialysis and vascular access system comprises a subcutaneous composite PTFE silastic arteriovenous fistula having an indwelling silastic venous end which is inserted percutaneously into a vein and a PTFE arterial end which is anastomosed to an artery. Access to a blood stream within the system is gained by direct puncture of needle(s) into a needle receiving site having a tubular passage within a metal or plastic frame and a silicone upper surface through which needle(s) are inserted. In an alternate embodiment of the invention, percutaneous access to a blood stream may be gained by placing needles directly into the system (i. e. into the PTFE arterial end). The invention also proposes an additional embodiment having an arterialized indwelling venous catheter where blood flows from an artery through a tube and a port into an arterial reservoir and is returned to a vein via a port and a venous outlet tube distinct and distant from the area where the blood from the artery enters the arterial reservoir. The site where blood is returned to the vein is not directly fixed to the venous wall but is free floating within the vein. This system provides a hemodialysis and venous access graft which has superior longevity and performance, is easier to implant and is much more user friendly.

An apparatus to prevent and/or treat pressure ulceration of the skin notably in the sacral area, but also other pressure-sensitive areas of the body as well. The apparatus includes a garment configured for placement about a region of a person, the garment having at least one bladder and at least one corresponding support surface configured to be maintained in a substantially fixed relationship relative to a portion of the region of the person and configured to provide controllable support to the person in this portion of the region. The at least one bladder is controllably inflated/deflated with a fluid. The apparatus can be configured to off-load the sacrum and reposition weight distribution in the sacral area to avoid skin ischemia and skin breakdown leading to pressure sores know as decubitus ulcers.

Described herein are systems and apparatuses for the prevention and treatment of pressure ulcers. In particular, the ulcer prevention systems and/or apparatuses disclosed herein prevent or otherwise mitigate pressure ulcers by actively orienting a patient over an anatomy-specific pressure-mitigating contact surface on which the patient rests. A pressure-mitigating contact portion of the contact surface includes a plurality of independently pressurized chambers configured in a specific geometric pattern that is designed to mitigate contact pressure between a support surface (e.g., table or chair) and a specific anatomic region of a patient's body when the specific anatomic region of the patient's body is oriented over an epicenter of the geometric pattern. A plurality of elevated side support portions are interconnected on the base material and configured to actively orient the specific anatomic region of the patient's body over the epicenter of the geometric pattern.

Described herein are systems and apparatuses for enhanced comfort through contact pressure reduction. In particular, the systems and apparatuses disclosed herein prevent or otherwise mitigate pressure by actively orienting a patient over an anatomy-specific pressure-mitigating contact surface on which the patient rests. A pressure-mitigating contact portion of the contact surface includes a plurality of independently pressurized chambers configured in a specific geometric pattern that is designed to mitigate contact pressure between a support surface (e.g., bed or chair) and a specific anatomic region of a patient's body when the specific anatomic region of the patient's body is oriented over an epicenter of the geometric pattern. In one embodiment, the geometric pattern includes a first independently pressurized relief chamber that intersects the epicenter of the geographic pattern, and second and third independently pressurized relief chambers that collectively encompass the first independently pressurized relief chamber.
