  • Publication number: 20230302267
    Abstract: The disclosure relates to a subcutaneously implanted port device for establishing access to the vascular system of a patient requiring multiple blood treatments over an extended period of time. The systems, devices and methods disclosed herein may reduce miscannulation, promote intra-session hemostasis, and decrease the incidence of bacteremia and sepsis among other improvements and advantages. The devices include a port with a tapered seat for receiving an access tube, the first tapered seat having a proximal portion, a distal portion, and a conical section extending between the proximal portion and the distal portion; and an interface surface configured to engage a blood vessel or a vascular access catheter. The proximal portion of the tapered seat is configured to receive the access tube therethrough, and the tapered seat creates a mismatch fit with a diameter of the access tube when in use for an increase in flow during treatment.

  • Publication number: 20190380898
    Abstract: A tilt-tip moldable bed system for the care of immobile patients is provided. The bed system may include a moldable mattress having a casing with a bladder defining an inner volume and a top compliant surface over a top surface of the bladder, the compliant surface configured to conform to a shape of a displacing structure. The bladder may be configured to hold a plurality of beads suspended in a fluid medium. The moldable mattress may be molded while inflated and maintain a resilient shape when evacuated. The system may further include a supporting frame for the moldable support structure having a laterally rigid outer rim with at least one attachment point for the moldable mattress, at least one attachment point for a netted sling, and one or more mounting tracks configured to support at least one peripheral attachment.

  • Patent number: 10456570
    Abstract: The present invention relates to subcutaneously implanted graft-port systems, devices and methods for establishing access to the vascular system of a patient requiring multiple blood treatments over an extended period of time. The systems, devices and methods disclosed herein reduce miscannulation, promote intra-session hemostasis, and decrease the incidence of bacteremia and sepsis among other improvements and advantages. The devices include a port with a flattened plateau-like surface for receiving an access tube. The flat surface may include a tactile or visual guide to assist with placement of the access tube into the tapered seat. Optional valve mechanisms reduce the size and form factor of the implantable graft-port device and seals the conduit of the port closed to physiologic pressures until the valve is opened upon percutaneous insertion of the access tube. The access tube does not pass into the conduit.

  • Publication number: 20110213025
    Abstract: Methods, compositions and kits are disclosed for infusing a hydrophobic catheter lock solution into an indwelling catheter. The combination of a tocopherol compound and at least one saturated mid-chain fatty acid provides a broad spectrum antimicrobial solution with optimal viscosity for effectively locking a catheter. The lock can effectively reduce or eliminate the risk of infection and prevents tainting the catheter, particularly clotting and thrombus in intravascular and extravascular catheters. The potential for this discovery is for maintaining or reestablishing the viability of an intravascular or extravascular catheter, as well as topical formulations for promoting healing.

  • Patent number: 5807356
    Abstract: A catheter with valve for implantation in a vascular structure of a living being. The catheter is in the general shape of a "T" with the top of the "T" implanted within the lumen of a vascular structure, and the leg of the "T" extending out of the vascular structure through an incision in the vascular structure. The lumen of the implanted portion of the catheter completely occupies the lumen of the vascular structure, causing all blood flow through the vascular structure to be directed through the implanted portion of the catheter. A valve is placed in the wall of the implanted portion of the catheter which opens into the lumen of the leg of the "T" of the catheter upon application of sufficient differential pressure between the lumens of the two portions of the catheter.

  • Patent number: 5755780
    Abstract: An implantable device grafted directly to vascular structures for high volume blood and/or fluid infusion and/or removal for such purpose as hemodialysis, apheresis, exchange transfusion, or large volume fluid infusion. The device is also adaptable to intermittent access to the venous or arterial circulations for purpose of blood sampling or giving medications. The device is comprised of an implantable fluid chamber connected to a vascular shunt which is then grafted directly to the vascular structure (e.g. artery or vein). The vascular end of the device employs a valve to prevent reflux of blood and subsequent washout of anticoagulant during periods when the device is not in use. The device is accessed percutaneously with a needle or needle-introduced catheter and is filled with anti coagulant prior to needle withdrawal to prevent thrombosis.

The device is also adaptable to intermittent access to the venous or arterial circulations for purpose of blood sampling or giving medications. The device is comprised of an implantable fluid chamber connected to a cannula or shunt segment which is then grafted directly to the vascular structure (e.g. artery or vein) using a sewable cuff located at the vascular end of the cannula or shunt segment. The vascular end of the device employs a valve which is directly adjacent to the vascular structure after grafting, in order to prevent reflux of blood and subsequent washout of anticoagulant during periods when the device is not in use. The device is accessed percutaneously with a needle or needle-introduced catheter and is filled with anti-coagulant prior to needle withdrawal to prevent thrombosis.
