VACUUM ASSISTED SKIN PENETRATING APPLIANCE WITH EXTERNAL INTERFACE
An external protective interface is provided for intravenous infusion lines, drive lines, vacuum lines, and monitoring lines for percutaneous access. The interface acts as an airtight seal in concert with a vacuum line to promote accelerated tissue healing to reduce and prevent infection at insertion sites for infusion lines, drive lines, and medical devices. The interface provides additional mechanical stability to an implanted tube or PAD or so as to speed healing around a semi-permanent implanted tube or PAD, as well as connection points for vacuum lines and at least one drive line for the insertion of medical devices. The dense fibroblast ingrowth encouraged by the interface acts to strengthen barriers to infection at the insertion site.
Method of Dialysis of Blood
The present disclosure provides a method for hemodialysis of blood, comprising providing a hemodialysis catheter having a low recirculation distal tip, a first and a second extension tubes that are configured to be connected to a dialysis machine, providing a hemodialysis machine with an arterial patient connector and a venous patient connector; conducting hemodialysis with the first extension tube connects to the arterial patient connector of the dialysis machine, and the second extension tube connects to the venous patient connector of the dialysis machine; and periodically reversing the first and second extension tubes connections to the arterial and venous patient connectors of the dialysis machine in a subsequent hemodialysis. The present disclosure also provides a hemodialysis catheter, comprising a switchable connection indicator indicating connection to arterial or venous flow path. The switchable connection indicator can be integrated with a clamp.
Medicated patch for preventing exit site infections during peritoneal dialysis
A medicated apparatus including a medicated patch for use onto a subject undergoing peritoneal dialysis is disclosed, according to an embodiment of a present invention. The patch includes a medication layer containing a medication therein, and a backing film disposed on one side of the medication layer. The patch also includes a skin adhesive layer disposed beneath the medication layer; and a protective liner disposed beneath the skin adhesive layer. The patch is placed on a catheter by applying pressure to skin of a subject after insertion of the catheter therein, thereby holding the catheter and the medication diffusing into the skin prevents an exit site of infection.
Single lumen drainage catheter with extendable and retractable drains
A single lumen catheter with extendable and retractable drains for providing improved fluid drainage and irrigation. The catheter generally includes a housing enclosing a single unpartitioned lumen, a plurality of drain ports, and a common drain. A plurality of drains provide a plurality of paths for fluid to flow between the common drain and the exterior of the housing. The plurality of drains are coupled to an internal connector within the single lumen, and are selectively movable via the internal connector and a stylet with a specially shaped end tip between a retracted position in which the drains are enclosed within the lumen and an extended position in which the drains extend through the drain ports to the exterior of the housing. Additionally or alternatively one or more elongated tools or other elements can be coupled to the internal connector and caused to move between retracted and extended positions.
Deploying split-tip hemodialysis catheter in a right atrium
A split-tip catheter and methods for deploying a split-tip catheter in a right atrium are provided. The catheter is configured with a distal portion including a first and a second distal end regions elastically divergable from alignment along a splitting plane to regain a relaxed configuration. The first distal end region terminates in a first tip having a first forward opening, and the second distal end region terminates in a second tip having a second forward opening. Catheter deployment may include directing the first forward opening generally towards an anterior right atrium wall portion and applying the first forward opening to withdraw blood from the right atrium.
Automated Peritoneal Dialysis Device
An automated peritoneal dialysis (APD) system using gravity to deliver fluid from one or more source dialysate bags to the patient as the destination, and using gravity to deliver fluid from the source patient to the destination drain container or drain receptacle, and heats at least one dialysate bag placed onto a heated plate, and using a disposable tubing set is used for dialysate delivery to and from the patient, and using one or more solenoid-operated, normally closed, electronically-controlled pinch valves which pinch or release the disposable tubing set's tubing to stop or start fluid flow, respectively.

METHOD FOR PERITONEAL REMOVAL OF ELECTROLYTES AND INFLAMMATORY MEDIATORS
A method of peritoneal removal of electrolytes and inflammatory mediators. The method begins with infusing a treatment solution into the peritoneal cavity of a patient by way of a catheter. The treatment solution is drained from the peritoneal cavity by way of the catheter. During the draining, the treatment solution is filtered for removing electrolytes and inflammatory mediators.
Implantable fluid management system having clog resistant catheters, and methods of using same
A fluid management system for moving bodily fluid accumulated due to ascites, pleural effusion or pericardial effusion is provided including an implantable pump coupled to an inflow catheter, an outflow catheter, and optionally an anti-clog catheter. The fluid management system facilitates removal of fluid from a body region, such as the peritoneum, pleural cavity or pericardial sac, where drainage is desired to another body region, such as the urinary bladder or the peritoneal cavity. The system includes clog resistant mechanisms such as clog resistant catheters and/or programmed routines for cycling fluid through inlet catheters in predetermined time intervals and/or responsive to sensed conditions to minimize the risk that inlet catheters become clogged due to, for example, tissue ingrowth and/or solid objects within accumulated fluid.
Method and apparatus for performing peritoneal ultrafiltration
Method and apparatus for ultrafiltration of a patient being overhydrated due to congestive heart failure, comprising a cassette having four inlets/outlets. A patient tube is connected to a patient connector, intended to be connected to a patient line for access to a peritoneal cavity of the patient. The patient tube comprises a flow pump for addition and removal of a peritoneal fluid between the cassette and the peritoneal cavity. The fluid is introduced into an intermittent bag controlled by an intermittent valve and then returned the same way back to the peritoneal cavity. Glucose is metered into the fluid entering the peritoneal cavity by means of a glucose pump. Glucose is replenished continuously or intermittently for keeping a concentration of the osmotic agent substantially constant in the peritoneal cavity. After treatment, the peritoneal fluid is drained to a drain bag, wherein the drain tube comprises a drain valve and an albumin filter.
