Hydrated catheter with sleeve

Embodiments provide a urinary catheter assembly comprising an outer package of gas-impermeable material and an intermittent urinary catheter arranged inside the outer package. The catheter comprises a proximal insertion end, a distal connection end, and a connector at the distal end. The connector defines a distal opening. The catheter assembly further comprises a sleeve of liquid-impermeable material configured to define at least part of a liquid tight enclosure. The enclosure encloses the insertable part of the catheter. The enclosure is closed by a first closure in the proximal end and a second closure in the distal end. The second closure is configured to be opened as the outer package is opened and the first closure is configured to be opened as the catheter and sleeve is removed from the outer package.

Introducer needle with notches for improved flashback
11744997 · 2023-09-05 · ·

A catheter system may include a catheter adapter, a catheter extending distally from the catheter adapter, an introducer needle extending through the catheter, a flash chamber in fluid communication with a needle lumen of the introducer needle, and a seal element. The introducer needle may include a wall defining the needle lumen, a first notch formed through the wall, and a second notch formed through the wall. The seal element may be proximal to the first notch and the second notch and within the catheter between an outer surface of the introducer needle and an inner surface of the catheter. The seal element may prevent priming fluid from travelling distal to the seal element. The seal element in conjunction with the first notch, the second notch, and the flash chamber may facilitate pressure-driven blood flow into the catheter for detection of flashback and transfixing when priming occurs prior to insertion into vasculature.

Indwelling valve actuated urinary catheter
11752302 · 2023-09-12 ·

An indwelling valve actuated urinary catheter has an inner catheter having an inlet port configured on a distal end and for locating within the bladder and a sheath that extends over the inner catheter to produce a valve. The sheath extends over the inlet port when the valve is in a closed position and manipulation of a valve actuator on the proximal end, located within the penis, opens the valve. A bladder plug configured on the distal end of the inner catheter may form a seal between the catheter sheath and the inner catheter. The valve actuator may comprise a proximal nodule and a distal nodule that are configured within the urethra along the penis. Manual manipulation of the valve actuator through the penis, such as by pinching the penis, moves the proximal and distal nodules with respect to each other to open or close the valve.

SMART OBTURATOR ASSEMBLY
20230143159 · 2023-05-11 ·

A smart obturator assembly includes a hub forming a central passage. The hub is configured to couple to a proximal end of a device that forms a lumen such that the central passage is in fluid communication with the lumen. A collar on the hub includes electronic circuitry in signal communication with remote reception circuitry. An obturator is movably positionable within the lumen. The obturator is movable within the lumen between a first position and a second position. The obturator includes a distal end and a sensor at the distal end. The sensor is configured to sense an environmental characteristic within a patient’s blood stream, generate a signal representative of the environmental characteristic, and transmit the signal to the electronic circuitry. The electronic circuitry is configured to receive the signal and transmit the signal to the remote reception circuitry.

INTERNAL BALLOON SHEATH

Devices and methods for providing an internal balloon sheath are disclosed. One device includes a sheath for insertion through an arteriotomy of a patient. The sheath comprises a tubular sheath body having a longitudinal axis, an open proximal end, an open distal end, an outer surface and an inner surface, the inner surface defining a lumen between the proximal and distal ends for passage of a catheter device. The sheath also comprises an inflatable balloon disposed within the lumen. The inflatable balloon is configured to occupy a longitudinal space in the lumen between the inner surface of the sheath body and the catheter device when the catheter device is disposed within the sheath and the balloon is inflated, and fluidically seal the lumen.

Stretch valve balloon catheter and methods for producing and using same

A safety balloon catheter includes a catheter having a stretch valve, a connector, a balloon inflated with an inflation fluid, a hollow inflation lumen extending through the catheter to the balloon and conveying inflation fluid thereto and therefrom, a hollow second lumen, and a balloon drainage port fluidically connecting the balloon to the second lumen. The stretch valve has a hollow base fixed in the second lumen at a proximal catheter end and shaped to permit a fluid therethrough and a hollow plug slidably positioned in the second lumen at a given distance from the base to, in a steady state, prevent inflation fluid from passing through the drainage port and, when actuated, slide within the second lumen to permit inflation fluid to pass through the drainage port and into the second lumen. The connector connects the base and the plug and has a length greater than the given distance.

REINFORCED BALLOON CATHETER

A balloon catheter is described having a reinforced, co-axial, duel lumen design. In some embodiments, the balloon catheter includes a purging mechanism designed to purge air from the balloon.
