Abstract: The disclosed technology described pertain to collection swabs that are designed to capture and retain specimen, tissue, or fluids from a patient. The collection swabs are generally inserted into a desired location, such as a nasal cavity. During the process of insertion, a user maneuvers the collection swab and in the process dislodges and collects various specimen, tissue, or fluids from the patient. The collection swab utilizes specially designed distal or tip portions and/or sleeves or cages in order to capture and retain the specimen, tissue, and fluids. The various designs associated with the distal or tip portion and the sleeve or cages affect not only how much specimen, tissue, or fluids can be collected but also how much of the specimen, tissue, or fluids can be retained after the collection swab is removed from the patient.

Abstract: Clip appliers to apply a surgical clip and methods concerning the same are provided. One provided applier has a cartridge and an actuator. The rack mechanism causes a feeder to move proximally as a closure member moves distally, such that jaw members move together to crimp a clip there between. The rack mechanism also causes the feeder to move distally as the closure member moves proximally, such that a crimped clip is released and another clip is fed into the jaw members. The rack mechanism further includes a rack connected to the closure member in which the closure member and the rack are arranged to move synchronously throughout the releasing of a crimped clip and feeding of another clip, e.g., an opening stroke.
