A medical device for the treatment and irrigation of a sinus opening is described. The device allows for single-handed operation to access, dilate and irrigate a sinus opening. The device includes a sinus guide catheter, a guiding element, a balloon dilation catheter, a balloon catheter movement mechanism and a guiding element movement mechanism. A method for treating a sinus opening and irrigating a sinus is also described.

Balloon dilation catheter system for treatment and irrigation of the sinuses

A system for delivering a fluid to a Eustachian tube (ET) of a patient includes a guide member and a tubular member. The guide member includes a shaft having a proximal portion, a distal portion, and a bend at the distal portion. The bend is configured to provide access to an opening in the ET. The system further includes a tubular member comprising a proximal end, a distal end, and a lumen extending therebetween. The tubular member is sized to fit within the ET. One or both of the tubular member and the guide member comprises a first stop member configured to engage the other of the tubular member or the guide member. The first stop member is configured to restrict a distal advancement of the tubular member relative to the guide member.

System and method for anesthetizing eustachian tube

An apparatus includes a proximal coil, a distal coil, a navigation sensor, and a wire. The proximal coil is formed by a wire wrapped in a helical configuration. The distal coil is formed by a wire wrapped in a helical configuration. At least one wrap at a proximal portion of the distal coil is interlocked with at least one wrap at a distal portion of the proximal coil, such that interlocking portions of the proximal and distal coils form a double helix configuration. The navigation sensor is located within the distal coil. The navigation sensor is configured to generate signals in response to movement within an electromagnetic field. The wire extends through the proximal coil. The wire is in electrical communication with the navigation sensor such that the wire is configured to communicate signals from the navigation sensor.

Navigation guidewire with interlocked coils

A guide catheter system for use in treating the sinus cavity or Eustachian tube is described. The system includes a guide catheter that has a proximal end and a distal end and an elongate shaft between the proximal end and the distal end and a guidewire. The guide catheter includes a deflection feature on a distal tip of the distal end for deflecting the guidewire at a predetermined angle.

Guide catheters with guidewire deflection features

An apparatus for delivering devices. The apparatus comprises a catheter with an elongated shaft having a first lumen and a second lumen extending therethrough. The apparatus further comprises a distal section with a lumen in communication with a port in a distal end of the catheter and with the first lumen and the second lumen. The first lumen is configured for a first device and the second lumen is configured for a second device to be disposed therein. The apparatus further comprises a proximal adapter coupled to the elongated shaft with a first port in communication with the first lumen and a second port in communication with the second lumen.

Dual needle delivery system

Embodiments include an infusion-occlusion system having a delivery catheter, a guide catheter adapted to receive the delivery catheter, and a guidewire with an occlusion device adapted to be received within the guide catheter. The guide catheter of the catheter kit may be provided with an occlusion device at the distal end of the guide catheter. The delivery catheter may have an accessory lumen, coaxial or co-linear lumen, a supporting mandrel, or an occlusion device at its distal end. Moreover, according to some embodiments, occlusion devices may be a single material or a composite balloon having an inner liner and an outer layer of different materials, a high compliance low pressure balloon, or a filter device that restricts particles from passing through but does not restrict fluid, such as blood. An inflation device with a large volume and low volume syringe can be used to inflate the balloon.

Infusion treatment agents, catheters, filter devices, and occlusion devices, and use thereof

An echogenic medical device, such as a needle catheter, which produces an improved ultrasonic image of the device, and a method of performing a medical procedure using a device of the invention. One aspect is directed to a catheter which reduces artifacts in the ultrasound image of the catheter. In one embodiment, the catheter has a spherical distal tip. Another aspect of the invention is directed to an echogenic catheter with echogenic portions arranged in an array to facilitate determination by ultrasonic imaging of the rotational orientation of the catheter relative to a desired location within the patient.

Echogenic needle catheter configured to produce an improved ultrasound image

Methods and apparatuses for the image guidance and documentation of medical procedures. One embodiment includes combining small field of view images into a recorded image of with a large field of view and aligning the small field of view real time image with the recorded image through correlation of imaging data. A location and orientation determination system may be used to track the imaging system and provide a starting set of image alignment parameters and/or provide change updates to a set of image alignment parameters, which is then further improved through correlating imaging data. The recorded image may be selected according to real time measurement of a cardiac parameter during an image guided cardiac procedure. Image manipulations planned based on the recorded image can be stored and applied to the real time information. The position of the medical device may be determined and recorded through manipulating a cursor in a 3-D image space shown in two non-parallel views.

Methods and apparatuses for image guided medical procedures

An apparatus including an expandable body; at least one delivery cannula coupled to an exterior portion of the expandable body; a needle having a protuberance thereon disposed in a lumen of the at least one delivery cannula; a stop disposed in the lumen of the at least one delivery cannula at a position distal to the protuberance on the needle. A method including positioning a catheter assembly including at least one needle delivery device disposed in an at least one delivery cannula, the at least one delivery cannula having an exit end; modifying the shape of the catheter assembly to modify the orientation of the exit end of the at least one delivery cannula at a region of interest; and advancing the at least one needle delivery device beyond the exit end of the at least one delivery cannula according to a controlled orientation.

Needle catheter

A deflectable catheter assembly and methods of use are herein disclosed. The catheter assembly, in one embodiment, is deflectable and includes a first catheter, a second catheter, and a third catheter. The second catheter fits coaxially within the first catheter. In some embodiments, the first and/or second catheter can be constituently different from proximal end to distal end. At least one of the first catheter and the second catheter include a deflectable portion to allow deflection of that catheter from a first position to a second position. The third catheter has a sheath and a medical instrument positioned within the sheath. The third catheter fits coaxially within the second catheter.

Deflectable catheter assembly

Delivery system for delivery of a medical device includes an inner member having a proximal section, a distal section and a longitudinal axis therebetween. The inner member has a first layer and a second layer wherein the first layer and the second layer are attached together at a first segment and a second segment. The second segment is spaced from the first segment along a length of the inner member and the first layer and the second layer are free of attachment between the first segment and the second segment. The inner member further includes at least two wires disposed along the length of the inner member between the first layer and the second layer. As disclosed, the at least two wires can include a first coil and a second coil moveable relative to each other between the first and second segments.
