A urinary catheter conveying device includes a sleeve member, a conveying assembly and a controller. The sleeve member is for sleeving onto a glans of a penis and has a guiding hole to be registered with an external urethral orifice of the glans. The conveying assembly includes a casing removably mounted to the sleeve member, and a conveying mechanism for advancing the urinary catheter to the guiding hole such that the urinary catheter is inserted into the external urethral orifice. The controller controls the conveying mechanism to advance the urinary catheter to the guiding hole. A urinary catheterization system and a method of using the urinary catheterization system are also disclosed.

A delivery apparatus is provided for inserting catheters and/or cannulae into a patient's blood vessel or body cavity either with or without the use of ultrasound imaging. The apparatus is used for the delivery of central venous catheters (CVCs) for creating a central line. The invention also relates to uses of the apparatus, and to methods for inserting catheters or cannulae (e.g. a CVC) into a patient.

Methods and related systems treating headache and migraine. The method may include producing an injury to a nerve at an identified location of hypersensitivity; wherein the identified location is a location of nerve hypersensitivity. The identified location may be within the anterior or frontal aspect of a nasal cavity, corresponding to a location of the V1 branch of the trigeminal nerve. Producing an injury may comprise providing cryotherapy to the identified location. The cryotherapy is supplied by a chilled probe, a cryo-balloon, a nasal spray device, or a gel applicator.

Methods and systems may quantify how much contrast fluid is injected into a patient by a powered fluid injector. A controller of the powered fluid injector can receive a command from a user to begin dispensing contrast fluid. The controller may determine whether a hemodynamic pressure signal is present from a pressure sensor in fluidic connection with the vasculature of the patient. The powered fluid injector may dispense a quantity of contrast fluid in response to the command. The controller may add the quantity of contrast fluid to an injection quantity if the hemodynamic pressure signal is present just prior to and/or just after the quantity of contrast fluid is dispensed. The controller may refrain from adding the quantity of contrast fluid to the injection quantity if the hemodynamic pressure signal is not present just prior to and/or just after the quantity of contrast fluid is dispensed.

Medical devices, perfusion systems, and methods for detecting a pressure within a space in a subject and for perfusion of fluid into a space in a subject. The space may be a fluid-filled space, or a space that is depleted of fluid due to an obstruction to fluid flow into the space. Methods for forming the medical devices.

An access device includes an access assembly for percutaneously accessing an anatomical space in a patient. An aspiration assembly is operable to generate negative pressure in a fluidic channel of the device. The fluidic channel places the access assembly in fluid connection with the aspiration assembly. A fluid tube has a first tube end connected to the access assembly, a second tube end connected to the aspiration assembly, and a tube body. The tube body defines a manometer tube portion spaced apart from both the first and second tube ends. The manometer tube portion acts as at least part of a manometer when the device is in a manometer mode. The manometer tube portion has adjacent first and second manometer tube ends and an inflection point substantially reversing the direction of the manometer tube portion at a location spaced apart from both the first and second manometer tube ends.

The present disclosure is directed to a catheter comprising a bendable catheter wall defining a substantially central interior lumen of the catheter, the catheter wall including a sealed chamber accommodating a fluid, the chamber substantially neighbouring the interior lumen and structured to be responsive to kinking of the catheter wall, the catheter further comprising a pressure sensor in fluid communication with the fluid, the pressure sensor configured to measure a pressure of the fluid, the pressure sensor further comprising an interface for communicating the measured pressure to a control unit, the catheter configured to allow for measurement of a change of the pressure in the fluid in response to kinking of the catheter.
