An intermittent catheter package including a plurality of components and a catheterization tray configured to facilitate a catheterization procedure. The plurality of components include a urinary catheter fluidly connected to a urine-drainage bag and a sampling-port access device configured to fluidly connect to a urine-sampling port of the urinary catheter or the urine-drainage bag for aseptic collection of one or more urine samples.The catheterization tray includes at least a first compartment, a second compartment, a third compartment, and a fourth compartment. The second compartment is connected to the third compartment Step-by-step surface instructions for performing the catheterization procedure are incorporated into the catheterization tray.

Various implementations include a system for coupling a needle to a port. The system includes a port and a needle. The port includes a reservoir and a lock box disposed within the cavity and defining a lock opening. The reservoir includes a membrane and a base coupled to the membrane, which together define a cavity. The reservoir is configured to be implanted under the skin of a person. The needle defines a lumen extending along a needle longitudinal axis. The needle includes a key disposed within the lumen. The key is movable from a first position to a second position. A portion of the key extends further in a radially outward direction in the second position than in the first position. A distal end of the needle is disposable within the lock opening such that the key is couplable to the lock box when in the second position.

A radially expandable trocar, port or cannula system is provided for use in minimally invasive surgeries. The cannula creates a port access with an initial small internal diameter. The passage of the cannula devices is defined by a plurality of elongate rigid members. A number of mechanisms are provided for expanding the passage of the cannula devices, by moving the plurality of elongate rigid members towards a larger radial location, thereby creating a larger internal diameter for the port. The elongate rigid members can be prevented from unintended movement when the system is at the un-expanded state, during expansion and when it is expanded to the desired larger diameter. Exemplary embodiments include methods of preventing gas loss from the tissue that would occur through the gaps created during expansion.

A urine-sampling system for aseptic urine sampling includes a catheter assembly and a sampling-port access device. The catheter assembly includes a urinary catheter, drainage tubing, and a connector fluidly connecting the urinary catheter to the drainage tubing. The connector includes a urine-sampling port. The sampling-port access device includes a tip at an end of a barrel configured to fluidly connect the sampling-port access device to the urine-sampling port of the catheter assembly. Each of the tip of the sampling-port access device and the urine-sampling port has a complementary fastening means for—fastening to the other of the tip of the sampling-port access device and the urine-sampling port. Each of the complementary fastening means ensures proper mating of the tip of the sampling-port access device and the urine-sampling port for aseptic urine sampling. In addition to various urine-sampling systems such as the foregoing, methods of use are also disclosed.

In some embodiments, a urine sampling kit is disclosed that includes a sampling port access device, a hand sanitizer pack, a pair of sterile gloves, and a packaged disinfectant wipe, wipe, or swab. The sampling port access device comprises a barrel and a hollow needle coaxial with the barrel, and the tip of the end of the barrel is configured to fluidly connect the sampling port access device to the urine sampling port of the catheter assembly. The needle is fluidly connected to but positioned away from the tip of the barrel. Contents of a urine sampling kit are packaged according to a gradual description of sterile urine sampling, including a sampling port access device, a hand sanitizer pack, a pair of sterile gloves and a packaged disinfecting wipe, wet tissue or swab. Also disclosed is a catheter insertion and urine sampling kit comprising at least some of the aforementioned components, as well as a method of sterile urine sampling using a urine sampling kit and a catheter insertion and urine sampling kit.

A port access needle extraction tool includes a housing defining an interior space, wherein the housing has a first end and a second end positioned opposite the first end, a needle engagement member positioned at least partially within the interior space, wherein the needle engagement member is configured to engage a portion of a port access needle, and a biasing member. The needle engagement member has an extended position and a retracted position, wherein the biasing member biases the needle engagement member toward the retracted position. Upon engagement of the needle engagement member with the portion of the port access needle, the needle engagement member is configured to move to the retracted position and retract the port access needle into the interior space of the housing.
