A medical tool includes, a deflectable distal end, at least a pull wire, and a coupling element. The at least pull wire has a first end coupled to the distal end of the medical tool, and configured to be moved for deflecting the distal end. The coupling element is coupled to a second end of the pull wire and having at least two boreholes configured to receive at least two respective rods traversing therethrough. The coupling element is configured to be moved along a rotation axis of a rotatable element coupled thereto, and the boreholes and the respective rods are configured to prevent rotation of the coupling element.

There is provided a device for eustachian tube treatments having a handle section with proximal and distal ends where the handle section has a dilator control with at least first and second positions. The dilator control is connected to a plate internal to the handle section, which is connected to an internal shaft. An insertion tube is connected to the plate and extends from the distal end of the handle section. A protective sleeve is inside of the insertion tube and connected to the plate. A dilator is connected at a first end to the plate and collapsed within the protective sleeve, with the dilator expanding when moved to a position external to the distal end of the insertion tube and the protective sleeve is withdrawn back into the insertion tube. The dilator maintains the eustachian tube open for delivery of laser energy or therapeutics to a desired treatment area.

Sinusitis and other disorders of the ear, nose and throat are diagnosed and/or treated using minimally invasive approaches with flexible or rigid instruments. Various methods and devices are used for remodeling or changing the shape, size or configuration of a sinus ostium or duct or other anatomical structure in the ear, nose or throat; implanting a device, cells or tissues; removing matter from the ear, nose or throat; delivering diagnostic or therapeutic substances or performing other diagnostic or therapeutic procedures. Introducing devices (e.g., guide catheters, tubes, guidewires, elongate probes, other elongate members) may be used to facilitate insertion of working devices (e.g. catheters e.g. balloon catheters, guidewires, tissue cutting or remodeling devices, devices for implanting elements like stents, electrosurgical devices, energy emitting devices, devices for delivering diagnostic or therapeutic agents, substance delivery implants, scopes etc.) into the paranasal sinuses or other structures in the ear, nose or throat.

A method is used to insert an implant within a lateral wall of a nose of a patient. The method includes forming an initial incision with a surface of the lateral wall of the nose. A stylet is advanced within the lateral wall of the nose, thereby creating a pocket within the lateral wall of the nose. The stylet is further advanced until an expanding body of the stylet is at least partially housed within the pocket of the lateral wall. The expanding body of the stylet is enlarged to thereby enlarge the pocket within the lateral wall. The implant is placed within the enlarged pocket of the lateral wall.

An implant delivery system includes a catheter, an implant, and a push body. The catheter extends from a first proximal end to a first distal end. The catheter defines an inner lumen extending through the first distal end. The implant includes a second proximal, a second distal end, and a plurality of resilient barbs. The implant is slidably housed within the inner lumen. The implant is compressed in the inner lumen such that the implant bears against an inner diameter of the inner lumen and the implant is retained within the inner lumen by friction. The push body is slidably housed within the inner lumen of the catheter. The push body is adjacent to the second proximal end of the implant.

Devices used to provide transseptal access are disclosed. The devices may comprise at least one cannula, a needle, and a handle. The cannula and the needle may be configured to be inserted through a dilator while not damaging a lumen wall of the dilator. The handle may be configured to lock the needle in a retracted position. The devices may be configured to telescopically advance the needle through an atrial septum.

Exemplary embodiments of devices and method for affecting at least one anatomical tissue can be provided. A configuration can be provided that includes a structure which is expandable (i) having and/or (ii) forming at least one opening or a working space through which the anatomical tissue(s) is placed in the structure. For example, the structure, prior to being expanding, can have at least one partially rigid portion. In addition, or as an alternative, upon a partial or complete expansion thereof, the structure can be controllable to have a plurality of shapes. Further, the structure can be controllable to provide the working space with multiple shapes and/or multiple sizes.

The present invention provides a medical device that may include a catheter body having proximal and distal portions, a fluid injection lumen disposed within elongate body, and a guidewire lumen disposed within the elongate body. A tip portion defining a cavity in fluid communication with the fluid injection lumen may be coupled to the distal end of the guidewire lumen, and an expandable element may be coupled to the distal portion of the catheter body and to the tip portion, such that the expandable element is in fluid communication with the fluid injection lumen. A shaping element may at least partially surround the expandable element, where the shaping element is configurable in a first geometric configuration and a second geometric configuration.

The present disclosure relates generally to the field of medical devices and methods to assist in the introduction of an instrument into a patient, and more particularly to medical devices for measuring and/or monitoring forces applied during introduction of an access sheath through a body lumen.
