Abstract
A puncture visualization device can include a guidewire having a proximal section, a distal section, and a distal tip. The device can include a needle having a needle lumen configured to receive the guidewire. The device can include a lock, and the lock can engage with the guidewire. For instance, engagement of the lock with the guidewire can inhibit relative motion between the guidewire and the needle. The device can include an optical sensor, for example located at the distal tip of the guidewire. The optical sensor can be locked into a position, for instance by the lock. In an example, the device provides a distal field of view from a location within the needle and near a distal end of the needle for visualization to facilitate puncturing a target with the distal end of the needle.
