Disclosed are puncture sealing systems and methods of locating a puncture site within a vessel. The systems can include elongated dilators and access sheaths that are configured to locate the puncture site within a vessel so that the position of the puncture site relative to a distal end of the access sheath is known during a puncture sealing procedure.

An elongate shaft management device has an upper plate and a lower plate. The lower plate has at least one groove that is sized to receive the elongate shaft. The at least one groove in the lower plate cooperates with the upper plate to capture the elongate shaft and prevent movement of the elongate shaft. The upper plate is releasably coupled to the lower plate to provide access to the elongate shaft and allow it to be manipulated.

The present invention relates to a medical kit and method of administration for trigeminal balloon compression used in the treatment of trigeminal neuralgia. The kit reaches the damaged area percutaneously and penetrates the balloon most effectively to the damaged spot. The present invention is a trigeminal neuralgic balloon compression kit which can overcome the aforementioned disadvantages; it is characterized by being a product kit and application method which has a simple structure and can easily and effectively convey the balloon to the damaged area.

An example vessel caliper according to the present disclosure includes a scale having a first clamp, and a slider movable relative to the scale such that a length measurement can be determined, the slider having a second clamp. Each of the first and second clamps have a spring action jaw configured to capture a catheter assembly therebetween. An example method of using the vessel caliper is also disclosed.

A catheter assembly having the major components: a cap, an introducer tip, four different variations of grip housing, a tube gripper and a catheter. The variations of the housing connected to the catheter assembly allows for safe and effective delivery of the anesthetics to various bodily orifices. The catheter is slowly advanced further while irrigating and dispensing the medication and/or lidocaine gel from the syringe. Once the desired depth is reached the practitioner can mark off the depth in centimeters on the catheter using a variation of the marker.

An instrument advancement device may include an instrument and an advancement feature configured to advance the instrument distally through the catheter assembly. The instrument advancement device may include a first indicator marking, a second indicator marking, and a third indicator marking. In response to aligning the advancement feature with the first indicator marking, a distal tip of the instrument may be configured to align with a distal tip of a catheter assembly. In response to aligning the advancement feature with the second indicator marking, the distal tip of the instrument may be advanced a distance distal to the distal tip of the catheter assembly. In response to aligning the advancement feature with the third indicator marking, the distal tip of the instrument may be advanced another distance distal to the distal tip of the catheter assembly.

A tapered dilator includes a plurality of cylindrical segments having a number of different diameters, a plurality of tapered portions, each of the plurality of tapered portions being disposed between adjacent ones of the plurality of cylindrical segments and serving as a transition between the adjacent ones of the plurality of cylindrical segments, and a plurality of markings disposed on an outer surface of each of the plurality of cylindrical segments.

This assembly for tracheal instillation of fluid medicaments, particularly in preterm infants supported by non-invasive ventilation, comprises a microcatheter, a guidewire and a gripper. The microcatheter consists of a very small gauge soft composite tube with a proximal connector and a distal rounded tip. Three circumferential color-coded bands near the rounded tip and a scale in one-centimeter increments on the soft composite tube guide the insertion depth positioning of the rounded tip under direct laryngoscopy. The slidably receptive guidewire within the central lumen of the microcatheter stiffens the soft composite tube for introduction and restores softness thereto after removal. Additionally, the guidewire is locked to the microcatheter during the introduction into the trachea to avoid injury. A gripper attached to the soft composite tube improves manipulation as well as estimated insertion depth control. Once the guidewire is removed, the fluid agent (e.g. surfactant) is slowly instilled into the neonatal trachea.

A balloon catheter having an elongated catheter shaft defining a fluid drainage lumen and a balloon inflation lumen. The balloon catheter includes a fluid drainage port disposed about the distal end of the catheter shaft in fluid communication with the fluid drainage lumen, and a balloon inflation port disposed about the distal end of the catheter shaft in fluid communication with the balloon inflation lumen. A balloon portion is disposed about the distal end of the catheter shaft in fluid communication with the balloon inflation port. A release device is disposed in fluid communication with the balloon portion and the fluid drainage lumen, and includes an activating member. A tether is attached to the activating member of the release device. Tension applied to the tether activates the release device, enabling fluid flow from the balloon portion into the fluid drainage lumen and out of the body.

An apparatus for treating a treatment area in the vasculature using a catheter having a balloon. The apparatus comprises a guidewire for guiding the balloon to the treatment area, said guidewire including one or more radiopaque markings arranged for corresponding to the treatment area. Related aspects and methods are also disclosed.
