摘要:
Devices and methods for delivering drugs and other therapeutic or diagnostic substances to desired locations within the bodies of human or non-human animal subjects. An implantable delivery device comprising a reservoir is initianlly attached to a deliver catheter or delivery tool and is introduced into the body and positioned at a desired site. A therapeutic or diagnostic substance is then introduced into the reservoir and the delivery catheter or deliver tool is then removed, leaving the implantable delivery device implanted within the body. The substance is then delivered from the reservoir at a rate that causes the desire diagnostic or therapeutic effect. Also provided are substance eluting stents that elute substance from a selected surface of the stent (e.g., the outer surface) but not from another surface of the stent (e.g., the inner surface).
摘要:
A method and apparatus for reducing or eliminating pain after surgical procedures related to mucosal tissue, including tonsillectomy, adenoidectomy, or other pharyngeal operations. Certain embodiments provide a biodegradable film or covering that serves as a mechanical barrier to reduce pain caused, for example, by friction between solid food and healing tissue in the first few days after surgery. Some embodiments may include one or more therapeutic substances for locally reducing pain, facilitating healing and/or otherwise treating mucosal tissue at or near a tonsil bed.

摘要:
Substance delivering spacer devices may comprise expandable reservoirs that are implantable in paranasal sinuses and other cavities, openings and passageways of the body to maintain patency and to provide sustained local delivery of a therapeutic or diagnostic substance. Also provided are sinus penetrator devices and systems for performing ethmoidotomy procedures or for creating other openings in the walls of paranasal sinuses or other anatomical structures.
摘要:
Devices, systems and methods wherein a dilator, such as a balloon or other expandable member, is positionable within the frontal sinus ostium and adjacent frontal recess and useable to dilate the frontal sinus ostium and substantially all of the frontal sinus recess without requiring repositioning and repeated re-expansion of the dilator. One balloon catheter device of the invention comprises a catheter body that is less than about 50 cm in length (and in some embodiments less than 25 cm in length and a semi-compliant or non-compliant balloon on the catheter body. The balloon may have a working length of about 12 mm to about 30 mm and a width at its widest point when fully inflated of about 2 mm to about 7 mm. Such balloon may be constructed to withstand inflation pressures of about 12 atmospheres. In some embodiments, the dilator is advanced through or over a guide (e.g., guidewire or guide catheter) that has a preformed shape.

摘要:
Devices, systems and methods useable for dilating the ostia of paranasal sinuses and/or other passageways within the ear, nose or throat. A dilation catheter device and system is constructed in a manner that facilitates ease of use by the operator and, in at least some cases, allows the dilation procedure to be performed by a single operator. Additionally, the dilation catheter device and system may be useable in conjunction with an endoscope and/or a fluoroscope to provide for easy manipulation and positioning of the devices and real time visualization of the entire procedure or selected portions thereof. In some embodiments, an optional handle may be used to facilitate grasping or supporting a device of the present invention as well as another device (e.g., an endoscope) with a single hand.
