One embodiment provides a support catheter member assembly, preferably for cardiac interventional procedures, comprising an elongated tubular body having proximal and distal ends, and a plurality of lumina extending axially therethrough. A plurality of support members extend through the catheter, exit at a defined distance from its distal opening, and reattach at its distal end. Manipulation of support members leads to their flexing outward/retraction towards the catheter, providing an adjustable support assembly with which the position of a separate guide catheter can be stabilized.

Self-washing catheter
20200129731 · 2020-04-30 ·

The present invention is a self-cleaning catheter designed to impede the development of biofilm within the catheter and provide a mechanism for removing biofilm within the catheter during use by a patient. The self-cleaning catheter includes an outer shell enclosing a urine lumen. The urine lumen has the ability to be opened and closed with a urine lumen closure device and is formed with a plurality of micro ports and a plurality of macro wash ports. At least one antimicrobial lumen is affixed to the exterior of and in fluid communication with the urine lumen at the plurality of micro ports. Similarly, at least one wash lumen is affixed to the exterior of and in fluid communication with the urine lumen at the plurality of macro wash ports. Antimicrobial solutions and wash solutions are introduced into the urine lumen by the antimicrobial lumen and wash lumen respectively, even during use.

10625045 · 2020-04-21 ·

An expandable intra-venous catheter for a faster intra-venous fluid challenge combination has a needle with a tip and an opposite base, a block receiving the needle axially, an inflator port in the block and an opposite IV port 5 in the block, the IV port has fluid communication into the needle, at least three inflators deployed along the needle outwardly from the block, the inflator port has gaseous communication into the inflators, a sheath extending from the block over the inflators towards the tip, and an IV tube upon the needle and within the sheath. The catheter has a flat state and an expanded state. The catheter minimizes the need for multiple access points and raises the rate of access success upon a practitioner's initial IV attempt.

Indwelling luminal devices

The invention comprises an indwelling medical device which is capable of delivering a therapeutic agent evenly along the length of the indwelling portion, including the outer wall, of the device.

20200085558 · 2020-03-19 ·

An attachment configuration for a vascular filter assembly including a self-expanding filter member attached to a catheter body and constrained from expansion in a first configuration by a constraining sheath is presented. The attachment configuration includes an outer tube of material that is overlaid over an end of the filter member and bonded to the catheter body through cutouts disposed through the end of the filter member.

INTRA-VENTRICULAR INFUSION AND EVACUATION CATHETER FOR TREATMENT OF INTRACEREBRAL HEMORRHAGE (ICH)
20200086083 · 2020-03-19 ·

A method of treating an anatomical cavity of a patient comprises introducing an infusion/aspiration catheter into the patient, such that a plurality of arms of the catheter reside within the anatomical cavity, delivering a fluid into the at least one of a connector, such that fluid exits the at least one fluid port of at least one of the arms, thereby infusing the anatomical cavity with the fluid, and aspirating the fluid into the at least one fluid port of at least one of the arms, such that the fluid exits the connector(s).

Medical drug delivery systems with mixing chamber
10589024 · 2020-03-17 ·

A drug delivery system provides for controlled mixing of drugs, using at least one mixing chamber. Flow controllers guide drugs into single or multiple catheters, enabling a single lumen catheter to dispense multiple drugs, diluting a concentrated drug to provide varying drug concentration. A buffer fluid can deliver precise drug amounts or can separate drugs within a catheter. A patient's bodily fluid can serve as a diluent or buffer fluid. A drug testing/filler apparatus may be used to facilitate filling of multiple reservoirs. Bolus or continuous delivery of drug to selected distal locations can occur at independent rates. New catheter systems, hub assemblies, and uses therefore are also described. New methods for promotion of healthy pregnancy and treatment of a developing fetus are disclosed.

MEDICAL MANIPULATOR AND MEDICAL DEVICE
20200078557 · 2020-03-12 · ·

A medical manipulator includes: an end effector provided at a distal side of the medical manipulator; a proximal housing provided at a proximal side of the medical manipulator; and an elongated portion coupled to both the end effector and the proximal end. The elongated portion includes: a first elongated member coupled to both the end effector and the proximal housing; a second elongated member coupled to only either one of the end effector and the proximal housing, the second elongated member being configured to form by surrounding the first elongated member; and to be slidable in a longitudinal direction relative to the first elongated member; and a third elongated member coupled to both the end effector and the proximal housing, the third elongated member being configured to form an exterior of the elongated portion by surrounding the second elongated member.

Devices and methods for providing focal cooling to the brain and spinal cord
10569064 · 2020-02-25 · ·

Systems and methods for systems and methods for focal cooling of the brain and spinal cord are disclosed. Some embodiments may be directed to a neuroprotection system that includes a cerebrospinal fluid processing platform. Embodiments may provide rapid and selective spinal cord hypothermia and drainage. Embodiments may be tailored to selective spinal cord cooling, pressure monitoring and automated drainage. Embodiments may enable local hypothermic neuroprotection, limit the stress of systemic cooling, minimize secondary neuronal damage and achieve maximal neuroprotection while at the same time improving workflow as a result of automated drainage. Embodiments may include a multi-lumen catheter, a drainage collection reservoir bag, a pump to circulate coolant, sensor hardware and controllers to modulate the flow of a heat transfer fluid for cooling to modulate therapeutic hypothermia and re-warming. Certain embodiments may include extracorporeal cooling of cerebrospinal fluid (CSF). Certain embodiments may include circulating heat transfer fluid within a CSF-containing space near the brain or spinal cord using a catheter. Particular methods may be used to determine the length and amount of cooling.
