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.

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.
