  • Patent number: 11938280
    Abstract: A drainage catheter system comprising a catheter having an elongate body \configured for insertion into an organ or cavity of a patient and a hub configured for coupling with a longitudinal shearing device and the first end of the catheter and movable over the elongate body of the catheter. A locking stay suture extends through the elongate body of the catheter. The length of the elongate body of the catheter can be adjusted by sliding the hub coupled to the longitudinal shearing device along the longitudinal axis of the catheter, and then creating a longitudinal cut in the catheter through which the proximal end of the locking stay suture can be removed and secured, thereby enabling the excess catheter tubing to be removed by cutting and allowing the base to rest flush against the patient's body.

  • Patent number: 11938257
    Abstract: The present invention presents a novel oxygenator of the invention provides a revolutionary engineering design and management of the flow regime in a completely different way from the existing and accepted regime in the field of oxygenators, that further lower the risk levels associated with the use of oxygenators and reduces the manufacturing cost. The revolutionary technology is aimed to divert the world of blood oxygenation from the use of technology that relies on a fiber membrane or gas bubbles and causes substantial damage to the patient's blood, towards the use of technology that allows the exchange of gases without a membrane at all and is aimed to reduces risks and improves patient outcome.

  • Patent number: 11878098
    Abstract: A method includes: receiving measurements of a blood-related parameter corresponding to a patient undergoing hemodialysis; estimating a value of one or more hemodialysis treatment-related parameters by applying a vascular refill model based on the received measurements of the blood-related parameter, wherein the one or more hemodialysis treatment-related parameters are indicative of an effect of vascular refill on the patient caused by the hemodialysis; determining, based on the one or more estimated values of the one or more hemodialysis treatment-related parameters, a hemodialysis treatment-related operation; and facilitating performance of the treatment-related operation. The vascular refill model is a two-compartment model based on a first compartment corresponding to blood plasma in the patient's body, a second compartment based on interstitial fluid in the patient's body, and a semi-permeable membrane separating the first compartment and the second compartment.

  • Patent number: 11871936
    Abstract: Embodiments of the present invention are directed to devices, systems and methods adapted for implementing intermittent displacement of blood to mitigate peripheral nerve neuropathy such as that induced by chemotherapeutic agents (i.e., chemotherapy-induced neuropathy (CIN)) that are administered to a patient. Such devices, systems and methods advantageously provide for precise, uniform and controlled blood flow occluding (and optionally blood displacing) compression along irregular surfaces of an appendage of a patient. Such precise, uniform and controlled blood occluding compression is imparted upon the epidermal and dermis skin layers within the aforementioned areas of a patient's extremities to decrease the time that free nerve endings located in the epidermal and encapsulated nerve endings located in the dermis skin layers are exposed to nerve damaging chemotherapy chemicals, thereby substantially decreasing CIN caused by prolonged exposure to such chemicals.
