Systems and methods for treating paranasal sinuses in a head of a patient include, for example, forming an opening through a canine fossa into a maxillary paranasal sinus and performing a procedure such as a balloon catheter dilation of the maxillary sinus ostium. In some embodiments, one or more procedures other than a balloon dilation procedure may be performed. In some embodiments, a combination of balloon dilation and one or more other procedures may be performed. Various approaches involve employing medical devices to accomplish alternative treatment modalities as well as taking alternative routes to the interventional site.

A mill for grinding marking particles utilizing a source of a pressurized fluid is provided. The mill includes a grinding chamber having a peripheral wall, a base and a central axis. The mill also includes a nozzle associated with the peripheral wall of the grinding chamber. The nozzle defines an inlet of the nozzle. The inlet is connectable to the source of pressurized fluid. The pressurized fluid propels the marking particles about the periphery of the chamber. The mill further includes a plug cooperable with the nozzle. The plug is in engagement the nozzle when the pressure within the grinding chamber is substantially greater than the pressure at the inlet of the nozzle. The plug is spaced from the nozzle when the pressure within the grinding chamber is substantially less than the pressure at the inlet of the nozzle, so that when the source of pressurized fluid is connected to the inlet, the plug is spaced from the nozzle permitting the entry of the pressurized fluid into the chamber and so that when the source of pressurized fluid is disconnected from the inlet, the plug is engaged with the nozzle preventing marking particles from entering the nozzle and clogging the nozzle.

A device for cleaning a lens of an endoscope inside a patient during a surgical procedure may include a cannula having a proximal end, a distal end and an opening, and an expandable member coupled with the cannula such that when fluid is introduced into the expandable member, it expands out of the opening in the cannula. A method for cleaning a lens of an endoscope inside a patient during a surgical procedure may involve: advancing a cannula into the patient; passing fluid into an expandable member coupled with the cannula to expand the expandable member, wherein some of the fluid passes through the expandable member to an outer surface of the expandable member; and contacting the endoscope lens with the outer surface of the expandable member, located inside the patient, to clean the lens.

A method of delivering nutrition and one or more pharmaceutical agents to a patient after obesity surgery to enhance the patient's nutritional intake and/or compliance with oral medication(s) may include: providing a food product in an amount suitable for fitting within a stomach of the patient after the obesity surgery, wherein the food product is formulated to include amounts of carbohydrate, fat, protein, vitamins, minerals and electrolytes to satisfy specific nutritional needs of the post-obesity-surgery patient; incorporating into the food product an effective amount of at least one pharmaceutical agent that modulates at least one of appetite, hyperlipidemia, hypertension, diabetes, sleep apnea, degenerative joint disease, or depression to produce a supplemented food product; and administering the supplemented food product to the patient after obesity surgery so as to enhance at least one of the patient's nutritional intake or compliance with oral medication.
摘要:
Systems and methods for improved power profiling of embedded applications are presented. These inventions provide the ability to measure the power consumption of an embedded application at the task level as the application is executing on the target hardware. Methods and apparatus are provided to permit such measurements in both real-time and non-real-time.

Disclosed is CPG, a combination of a chlorhexidine salt (such as chlorhexidine digluconate, chlorhexidine diacetate, or chlorhexidine dichloride) and n-propyl gallate that can be used at ambient temperatures as a urine preservative.
摘要:
A data processing system including a processor that executes a plurality of instructions including at least one instruction that requires an external operation to be performed. The processor provides information for this external operation instruction to an external device and continues to execute instructions that do not require the results from this external operation. The external device receives the information from the processor, performs the external operation and provides the results to the processor. A further aspect of this data processing system is an interface that is interconnected between the processor and the external device. The processor provides the external operation information to the interface. The interface in turn provides the information to the external device and concurrently accesses data from the memory that will be required by the external device for performing the external operation.
