A catheter comprises a catheter shaft having a fluid channel, an ultrasound transducer and a compliant balloon mounted on the catheter shaft and having an interior in fluid communication with the fluid channel and containing the ultrasound transducer. The compliant balloon includes a balloon wall having a working section radially surrounding the ultrasound transducer. The working section has a predetermined straightness when the working section has a first diameter and when the working section has a second diameter that is at least 2 mm greater than the first diameter. Other embodiments are also described and claimed.

Systems, products, compounds and methods can be applied and/or used by a person to facilitate and promote the production of nitric oxide to be used by a person for health benefits. The systems, products, and devices include a nitric oxide nasal delivery system. The system can comprise one or more containers for compounds that when mixed are adapted to produce nitric oxide gas, at least one container with a nitrite compound and at least one container with an acid compound. Containers can be ruptured so that the compounds may be mixed and produce nitric oxide gas. The nitric oxide gas may then be delivered to a user via one or more of the nasal cavities and/or mouth.

A method for operating a breastpump unit for expression of human breastmilk and various breast shields for use in this method allow a maximum pumping performance and a minimum pumping duration per pumping session. The breast shield has an inner chamber for receiving a nipple of the breast and also at least one outer chamber which at least partially surrounds the nipple. The inner chamber is subjected to a constant pressure and the at least one outer chamber is subjected to a pulsating pressure.

A foam inhalation device (874) for dispensing a foam to be inhaled by a user. The inhalation device (874) comprises a foam-generating component for generating the foam, an outlet (882) for dispensing the foam to the user, and a fluid flow path which fluidly communicates the foam-generating component with the outlet (882). The foam is generatable by the foam-generating component and flows to the outlet (882) via the fluid flow path to be inhaled by the user.

A cushion/frame assembly for a patient interface includes a cushion frame and a cushion. The cushion frame includes a cushion frame material, an annular wall portion having an opening that extends along a cushion frame longitudinal axis, and a projection extending radially with respect to the opening. The cushion frame is configured to snap fit with an outer frame having headgear attachment points and being configured to engage an inlet conduit. The cushion is connected to the cushion frame. The cushion is structured to form a seal with the patient and includes a cushion material that is more flexible than the cushion frame material.

An implantable medical device is provided for controlled drug delivery within the bladder, or other body vesicle. The device may include at least one drug reservoir component comprising a drug; and a vesicle retention frame which comprises an elastic wire having a first end, an opposing second end, and an intermediate region therebetween, wherein the drug reservoir component is attached to the intermediate region of the vesicle retention frame. The retention frame prevents accidental voiding of the device from the bladder, and it preferably has a spring constant selected for the device to effectively stay in the bladder during urination while minimizing the irritation of the bladder.

A patient interface including a seal-forming structure with a textile membrane that has at least one hole such that the flow of air at a therapeutic pressure is delivered to at least an entrance to the patient's nares and/or an entrance to the patient's mouth. The seal-forming structure is constructed and arranged to maintain the therapeutic pressure in a cavity of a plenum chamber throughout the patient's respiratory cycle, in use. The textile membrane includes a first portion that is held in a relaxed state and a second portion that is held in a taut state. The taut state of the second portion is configured to allow the seal-forming structure to include a three-dimensional shape that has multiple curvatures.

A patient interface structure includes a cushion configured to sealingly engage the patient's face and a front that is more rigid than the cushion. The cushion includes a forward opening, a rearward opening that is opposite the forward opening and a continuous sealing surface. The continuous sealing surface has a mouth sealing portion configured to seal around the patient's mouth and a nasal sealing portion configured to seal around both of the patient's nasal airways. The front plate includes an air inlet configured to both receive the pressurized respiratory gas and secure headgear to the patient interface structure. In addition, the nasal sealing portion includes at least one aperture that is separate from the rearward opening. Also, the front plate, the mouth sealing portion and the nasal sealing portion together form a common chamber.

Laryngeal airway devices for human and veterinary use include an airway tube having a distal end and a proximal end. The distal end of the airway tube is provided with a pre-formed and non-inflatable peri-pharyngeal bowl. The peri-pharyngeal bowl has a posterior bowl portion having a back dorsal portion and a side wall extending around and depending from the periphery of the back dorsal portion to define an internal space, and further having a resiliently deformable flange extending laterally from the side wall of the back dorsal portion which defines an extended internal space, the resiliently deformable flange has inner and outer surfaces that extend to a circumferential edge.

An ablation system comprises: an ablation catheter and a console. The ablation catheter comprises: a shaft including a proximal end, a distal portion and a distal end; an ablation element configured to deliver energy to tissue; and a force maintenance assembly comprising a force maintenance element and configured to control and/or assess contact force between the ablation element and cardiac tissue. The console is configured to operably attach to the ablation catheter and comprises: an energy delivery assembly configured to provide energy to the ablation element. Methods of ablating tissue are also provided.
