Abstract: Apparatus and methods for clearing obstructions from a medical tube are disclosed. In an exemplary embodiment, a spool drive system is disclosed for actuating a guide wire within a medical tube. The spool drive system can be a hand held, disposable device having a spool housing with a spool therein for alternately advancing and withdrawing a guide wire through an inlet of the spool housing. A track can be spaced from and extend about a perimeter of the spool to direct the guide wire onto or off of the spool as the spool is rotated. Other embodiments and devices for actuating the guide wire, and methods therefor, also are disclosed.

Abstract: A replaceable shuttle for actuating a clearance member. The replaceable shuttle including a shuttle body having an elongated recess formed therein and accessible through a longitudinally-extending, lateral mouth thereof. A magnetic element is disposed within the shuttle body adjacent to the elongated recess. The magnetic element is adapted to be magnetically coupled to a magnetic guide of the clearance member disposed within a tube when such tube is received in the elongated recess through the lateral mouth so that translation of the shuttle body will induce a corresponding translation of the clearance member through the tube.

Abstract: A device for clearing obstructions from a medical tube includes a housing defining an interior, an exterior, and a port providing fluid communication therebetween. The device further includes an elongated guide wire residing at least partially within the housing, and first and second rollers defining a nip therebetween that are located within the housing. A guide wire extends through the nip and is drivable for advancement and retraction thereof through the port via rotation of the rollers.

Abstract: Annuloplasty rings are employed to treat heart valve defects, such as regurgitation. Synching the heart tissue to the ring restores the valve opening to its approximate original size and operating efficiency. Adjustable annuloplasty rings allow for a proper degree of synching both during open heart surgery and over the patient's lifetime. A subcutaneous port may be coupled to an adjustable annuloplasty ring such that an external activation energy generator can be used to heat the adjustable annuloplasty ring and thereby adjust the size of the annuloplasty ring.

Abstract: A system for treating a cardiac valve includes an adjustable annuloplasty ring configured to attach to or near a cardiac valve annulus. The system also includes a suture comprising a first end coupled to the annuloplasty ring. A second end of the suture is configured to be anchored to a papillary muscle. Selectively adjusting the annuloplasty ring adjusts a tension of the suture to reposition the papillary muscle.

Abstract: The present invention relates to an artificial nucleus pulposus implant that is injected minimally invasively into the nucleus cavity of the annulus fibrosus to restore the normal anatomical and physiological function of the spine in the affected disc segment. In one aspect of the invention, a device is disclosed for delivering a phase changing biomaterial to a tissue site, the device comprising a dispenser including (i) a plunger having a proximal portion and a distal portion, an inlet end and an outlet end, (ii) a dispensing actuator attached to the proximal portion of the plunger, and (iii) a cartridge adapted to be inserted into the inlet end of the plunger for containing the phase changing biomaterial in a fluid state. The dispenser may be mechanically, pneumatically or hydraulically actuated. The dispenser may further comprise a nozzle attached to the cartridge for dispensing the biomaterial to the tissue site.

Abstract: A cooking appliance which is capable of rapidly toasting a food product disposed therein by air impingement and infrared heating to provide a cooked food product having the desired color and crunchiness about its surface. The appliance is particularly adapted for cooking sandwich products, toasting the bread and heating the sandwich filler. The appliance includes an air impingement assembly that delivers columns of heated air to the food product and an infrared heater assembly that produces infrared energy. The appliance delivers the impingement air from above the food product and the infrared energy from below. Alternatively, the appliance delivers the impingement air from above and below the food product and the infrared energy from below.

Abstract: A combination convection/microwave oven in which a food product is cooked by microwave energy and by a heated airflow provided by a thermal energy source and a blower. The oven is capable of cooking food in a microwave reflective pan. Microwave energy enters the oven below the pan and is guided to a spacing between the pan and oven sides and then reflected by the sides and top of the oven to the food product in the pan. The heated airflow is laminar with an upper layer and a lower layer. The pan is positioned at about the interface of the two layers so that the upper layer is incident on the food product and the lower layer is incident on the bottom of the pan.
