Described here are expandable devices and methods for using them. The devices generally comprise a hub and a plurality of legs extending therefrom. In some variations, the hub may comprise one or more domed portions, tapered portions, or the like. The legs may comprise one or more straight segments, one or more curved segments, or a combination thereof. The devices may comprise one or more polymers, and/or one or more portions of the device may be configured to biodegrade. In other variations, the device may be configured to release one or more drugs therefrom. Additionally, in some variations the devices may be configured to be self-expandable from a low-profile configuration to an expanded configuration.

It is provided a method of producing high-quality engineered cartilage graft in a human of animal, such as nasal cartilage graft, comprising expanding chondrocytes and/or chondroprogenitors, e.g. autologous human nasoseptal chondrocytes (hNC,) from a donor patient by selecting expanded chondrocytes and/or chondroprogenitors by detecting the expression of at least one surfaceome protein gene or secretome protein gene, wherein the at least one surfaceome protein gene is ADGRG1, NPR3, SLC16A4, TSPAN13, FZD4 and SLC22A23 and the at least one secretome protein gene is ADGRG1, B3GNT7, COLGALT2, IGFBP3, STC2, SAA1, ANGPLT1, COL8A2, INHBB, ADAMTS9, ORM1, COL14A1, DCN, COL21A1, ENOX1, IL7, MXRA5 GAL, TFRC, SERPINA9, LIF, GDF6 and COL5A3.

Nonsurgical methods of modifying at least a portion of a nose of a subject, such as a tip of the nose of the subject, are provided herein. The method can include performing one or more of a first injection of a first filler composition and a second injection of a second filler composition. The first injection includes depositing the first filler composition in a first region defined as a septal space behind a middle crura and a medial crura of the nose, substantially level and/or above an anterior nasal spine of the nose, and in front of a caudal septal cartilage of the nose. The second injection includes depositing the second filler composition in a second region defined as the septal space behind the middle crura and the medial crura of the nose substantially level with the footplates of the nose and the columella segment of the medial crura of the nose.

Described here are delivery devices for delivering one or more implants to the body, and methods of using. The delivery devices may deliver implants to a variety of locations within the body, for a number of different uses. In some variations, the delivery devices have a cannula with one or more curved sections. In some variations, a pusher may be used to release one or more implants from the cannula. In some variations, one or more of the released implants may be a self-expanding device. Methods of delivering implants to one or more sinus cavities are also described here.

A nasal implant delivery tool includes an inner handle, an outer handle, a needle, and a push rod. The inner handle includes a loading chamber configured to receive a nasal implant. The outer handle is configured to move axially relative to the inner handle. The needle extends distally from the inner handle and has a central lumen and a distal opening. The push rod is configured to move the nasal implant from the loading chamber, through the central lumen, and out the distal opening of the needle. The push rod is coupled to the outer handle such that the push rod moves axially relative to the inner handle when the outer handle is moved axially relative to the inner handle. Also described herein are nasal implant guides and methods of using nasal implant delivery tools and nasal implant guides.

This disclosure describes, inter alia, materials, devices, kits and methods that may be used to treat chronic sinusitis.

Devices and methods for treating a diseased tracheobronchial region in a mammal. The device can be a stent which can include a sustained-release material such as a polymer matrix with a treatment agent. The stent can be bioabsorbable and a treatment agent can be incorporated therewith. A treatment method can be delivery of a stent to a tracheobronchial region by a delivery device such as a catheter assembly.

Described here are systems, devices, and methods for delivery of an implant to a bodily cavity. The implant may include a hub and a plurality of legs, and may be moveable between a low-profile and expanded configuration. The systems may include a crimping device having a crimping member with a plurality of arms. The plurality of arms may engage the plurality of legs of the implant, and may move the legs to move the implant to the low-profile configuration. In some instances a delivery device may aid in crimping and/or delivery of the implant.
