An ENT tool has a tool chassis having a chassis channel and a tool chassis distal end. A tubular probe is dimensioned to be inserted into a human patient orifice, the probe is rotatable about a probe axis of symmetry, and the probe has a probe proximal end rotatingly connected to the tool chassis distal end. A balloon insertion mechanism is slidingly located within the chassis channel, and is configured to fixedly accept a balloon sinuplasty mechanism penetrating the tubular probe. A guidewire adjustment section is fixedly attached to the balloon insertion mechanism, and the section has a rotatable enclosure. A plurality of rollers are disposed within the enclosure and are configured so that on rotation of the enclosure the rollers grip and rotate a guidewire positioned between the rollers, and, absent rotation of the enclosure, release the guidewire and permit distal and proximal translation of the guidewire.

A system and method include operation of a device coupled to a base to hold a catheter to the base, the catheter defining a lumen in which a portion of an elongated medical device is disposed, and a portion of the catheter being disposed in a hemostasis valve, movement of the base relative to the hemostasis valve along a first path while the catheter is held to the base such that the catheter moves relative to the hemostasis valve, and operation of a mechanism coupled to the base to maintain a position of the elongated medical device within the lumen relative to the hemostasis valve while the base and the mechanism are moved along the first path and the catheter is held to the base.

The present disclosure provides a guide wire system comprising (a) a guide wire having a distal end and a proximal end, wherein the guide wire comprises a superelastic material, (b) a first connector coupled to the proximal end of the guide wire, (c) a second connector coupled to the guide wire between the distal end and the proximal end, (d) an electromagnetic sensor coupled to the distal end of the guide wire, and (e) a polymeric tube surrounding the guide wire and at least a portion of the electromagnetic sensor.

An introducer needle assembly including a compressible section between a rigid needle and a hub. Once a vessel is entered as determined by blood entering a syringe, the compressible section of the introducer needle is occluded by compressing the compressible section with a thumb and a finger. Neither blood nor air can pass. Since the compressible section is in a flattened area it is easier to hold the needle while the syringe is unscrewed. An operator then can begin threading a guidewire down a divide which is now easier to enter because blood is not coming out of the hub thus obscuring a lumen.

Examples of catheter devices, removable needle devices and kits are disclosed. Also methods for accessing a hollow organ are disclosed. The catheter devices include a body extending longitudinally from a proximal end to a distal end, wherein the body includes an elongated channel along a longitudinal length of the body extending from the proximal end to the distal end of the body, wherein the elongated channel is configured to receive an elongated needle of the removable needle device, and the body includes one or more cutting edges extending in a proximal direction from the distal end of the body. The body of the catheter devices includes one or more recesses adapted to mate with one or more catches of the removable needle device for coupling the needle device to the catheter device. Methods of using the catheters, removable needle devices and the kits are also disclosed.

A guidewire introducible into a bodily lumen having an obstruction therein is provided. An introducer needle is advanced through tissue and into the bodily lumen. A guidewire is advanced through the introducer and into the lumen. The guidewire is advanced further through the lumen until an atraumatic distal tip of the guidewire encounters an obstruction the distal tip cannot pass in a straight forward manner. The distal tip is pressed against the obstruction such that a flexible segment proximal of the distal tip forms a loop distal of the distal tip. The guidewire is advanced further through the lumen such that the loop of the flexible segment is pushed past the obstruction and the distal tip is pulled distally past the obstruction. A greater diameter guidewire extension can be coupled to the back end of the guidewire, providing function as a larger diameter guidewire.

A guide wire gripping device is provided that includes: a sheath; an advanceable and retractable part extending along the longitudinal axis of the sheath; an operation control that moves the advanceable and retractable part along the longitudinal axis; a grasping portion having a contact surface having a peripheral edge surrounded by a distal end, a proximal end, and a pair of side ends; and a support part connected to the advanceable and retractable part and fixed to one of the pair of side ends.

Disclosed catheter insertion systems enable the user to identify the location of the needle based on the electrical properties of subcutaneous tissue relative the electrical properties of other fluids such as blood or air. Disclosed systems can include one or more of the following features: 1) the catheter assembly is modular (e.g., the catheter can be connected and disconnected from the detection unit at will); 2) the detection unit employs an electrical circuit that allows for the discernment between subcutaneous tissue and blood; 3) the system assists the end user with catheter advancement. Some embodiments can be used to insert catheters into a spaces where the needle passes first through subcutaneous fat and muscle before entering fluid or air.

Methods and devices for trans-jugular carotid access are disclosed. Methods within the scope of this disclosure include methods of trans-jugular carotid access originating in the leg of a patient or other location remote to the jugular vein and carotid artery and methods originating at the neck of a patient. Devices used in connection with the disclosed methods may comprise access catheters, lumens, and stylets.

Disclosed is a device for facilitating placement of a central line in a patient, said device comprising: a housing having proximal and distal ends and a central portion therebetween, said housing having an upper portion and a lower portion; a handgrip provided on the proximal end of the housing, said handgrip having at least one of a channel and a through hole extending from the proximal end to the central portion, wherein the channel or through hole is sized to receive a guidewire; a feeder tip receiver provided on a proximal end of the handgrip in communication with the channel or through hole in said handgrip; a stabilizer provided on the lower portion of said housing; a luer slip tip provided on the distal end of the housing, said luer slip tip having a mounting portion for attachment to a needle hub, said luer slip tip having a lumen aligned with the channel or through hole in said handgrip; and a wire slide platform provided on the central portion of the housing.
