Described herein are methods and devices for delivering a drug to the frontal sinus system. An inflatable implant is positioned within the frontal sinus system using an anchoring means secured within the frontal sinus cavity. A drug-containing fluid is released directly into the frontal sinus drainage system.

A method of forming a three-dimensional object is carried out by providing a carrier and an optically transparent member having a build surface, the carrier and the build surface defining a build region therebetween; filling the build region with a polymerizable liquid; irradiating the build region through the optically transparent member to form a solid polymer from the polymerizable liquid and advancing the carrier away from the build surface to form the three-dimensional object from the solid polymer, while also concurrently with the irradiating and/or advancing steps: (i) continuously maintaining a dead zone of polymerizable liquid in contact with the build surface, and (ii) continuously maintaining a gradient of polymerization zone between the dead zone and the solid polymer and in contact with each thereof. The gradient of polymerization zone comprises the polymerizable liquid in partially cured form (e.g., so that the formation of fault or cleavage lines between layers of solid polymer in the three-dimensional object is reduced). Apparatus for carrying out the method is also described.

Method and system for treating a patient using a compressible, pressure-attenuating device. According to one embodiment, the system is used to treat urinary tract disorders and comprises an access device, a delivery device, a pressure-attenuating device, and a removal device. The access device may be used to create a passageway to an anatomical structure, such as the patient's bladder. The delivery device may be inserted through the passageway created by the access device and may be used to deliver the pressure-attenuating device to the anatomical structure. The removal device may be inserted through the passageway created by the access device and may be used to view the bladder and/or to capture, to deflate and to remove the pressure-attenuating device.

The delivery system may include, for example, an outer catheter having a distal tip and an inner support member, such as an inner catheter, disposed within the outer catheter. The inner support member includes an anchor member adjacent a distal tip of the inner support member and a support portion axially inward of the anchor member. The support portion is configured for supporting an implantable device thereon. A diameter of the anchor member corresponds to a diameter of a portion of a vessel in which the anchor member is to be disposed. The anchor member is configured to be lodged in the portion of the vessel to locate an intended position of the anchor member and to prevent movement of the inner support member relative to the vessel during release of the implantable device.

A gastrointestinal balloon system includes a gastrointestinal balloon and a check valve located within the gastrointestinal balloon. The check valve is configured to allow fluid flow into and out of the gastrointestinal balloon. The check valve includes a string coupled to the check valve, the string having a loop on a proximal end and a catheter having a lumen. The lumen is configured to receive a grasping tool. The grasping tool extends out a distal end of the catheter for grabbing the loop to align the catheter with the check valve. Also, a check valve, two-wat valve, and method of using the same in a gastrointestinal balloon.

Disclosed is an adjustable occlusion device for use in a body lumen such as the left atrial appendage. The occlusion device is removably carried by a deployment catheter. The device may be enlarged or reduced to facilitate optimal placement or removal. Methods are also disclosed.

Various aspects of the present disclosure are directed toward apparatuses, systems and methods that include arranging an implantable flow restriction device within the aorta of a patient. The methods may also include physical dimensions of the implantable flow restriction device.

The present disclosure relates generally to the field of cryotherapy. In particular, the present disclosure relates to cryotherapy catheters and systems that utilize a detachable expandable member to prevent or significantly inhibit cryogen gases from accumulating and progressing distally beyond a specific region within a body lumen.

A method for recycling a used balloon catheter includes accepting a used balloon catheter. The balloon catheter includes a detector that detects a state value including at least a pressure generated in a pipe path formed within the balloon catheter and a storage that stores a result of detection of the state value by the detector. The method includes determining at least one of reusability of the used balloon catheter and a method of recycling the used balloon catheter, based on the result of detection stored in the storage of the used balloon catheter.
