Abstract: A cannula may include a cannula bowl having an opening to receive an instrument configured to be advanced through the cannula, and a cannula tube extending distally from the cannula bowl. The cannula tube may have a proximal end opening, a distal end opening disposed at an opposite end of the cannula from the proximal end opening, and lateral wall defining a passage extending from the proximal end opening to the distal end opening. The lateral wall can have outer dimensions defining a waisted portion with smaller outer dimensions than a region disposed proximally or distally to the waisted portion along a length of the cannula tube.

Abstract: Fourth toe processing apparatus and methods for the processing the fourth toes of a bird are disclosed.

Abstract: An embolic coil deployment system for placing a coil at a preselected site within a vessel of the human body is provided. The deployment system includes a heating element at the distal end of a detachment member and a heat-responsive coupling attached to a delivery member for holding the coil during positioning of the coil. The heating element is heated to reduce the strength of and sever the heat-responsive coupling for releasing the coil at a desired position within the body vessel.

Abstract: A system for providing wireless remote control over one or more devices. Included in the system is at least one wireless button that can be placed at various locations and which communicates with at least one sensor when the wireless button and sensor are brought within close proximity to one another. According to one embodiment, a wireless button can only be activated when the button is located within an authorized activation area. In another embodiment, a wireless button can only be activated by an authorized user. In yet a further embodiment, a wireless button can only be activated by an authorized user when the button is located within an authorized activation area.

Abstract: Apparatus and methods for delivering a composition to a bird. A selected dosage of the composition may be delivered directly to one or both nostrils of the bird. The deliveries are performed through one or two fluid passages that are preferably in direct fluid communication with the birds' nostrils. Delivery of the composition may limited to only one nostril or both nostrils of each bird. The nostril or nostrils to which the selected dosages are delivered may be isolated from fluid communication with ambient atmosphere during the delivery process. The isolation may be provided by a conformable seal. The beak of the bird may be restrained in a closed position during delivery of the composition.

Abstract: The present invention provides apparatus and methods for treating the beaks of poultry to prevent further growth by non-contact heating while protecting the birds' tongues. The birds' tongues are protected by providing pressure on underside of the lower beak of the bird, proximate the base of the lower beak.

Abstract: Apparatus and methods for treating the upper and lower beaks of poultry by non-contact heating of the upper and lower beaks of the bird are disclosed. The upper and lower beak treatment may include delivery of energy to the upper and lower beak in amounts sufficient to retard the growth and/or result in erosion of portions of both the upper beak and the lower beak. The energy incident on the lower beak may be reflected from a lower beak energy director (e.g., a reflector) or it may be provided a separate energy source.

Abstract: An introducer having an elongate tubular member and a device connector releasably attached to a proximal end of the tubular member. The introducer allows exchange of medical instruments, such as a blood filter and cardioplegia catheter, through a single lumen. An obturator having a retractable blade for making incision on a tissue is insertable through the lumen of the introducer. Methods of using the obturator and the introducer for introducing medical device(s) into body cavity, such as a vessel or cardiac tissue, are also disclosed.

Abstract: A portable system moving a debeaker apparatus within a barn to reduce the transportation and handling of a bird. A frame which holds the debeaker apparatus, a receiving chute, a staging cage, a delivery chute and a first and second storage baskets has wheels for easy movement from one location to another location. In a barn, an operator removes a plurality of birds from a starter cage and places the birds in the receiving chute which directs the birds to a platform in the staging cage. The platform has an inclined surface such that the birds have a tendency to face away from the operator. This orientation of the birds assists in the alignment with respect to a head retaining member of the debeaker apparatus. The operator selects a bird from the platform in a staging cage for presentation to the head retaining member associated with the debeaker apparatus. Once a bird is accepted by the head retaining member, a containment shield is resiliently positioned adjacent opening in the top or the return chute.

Abstract: An instrument for the penetration of tissue, including a backstop assembly having a shaft and a backstop; and a penetration member slidingly engaged with the backstop shaft, and configured for penetrating tissue. The backstop assembly and the penetration member are configured such that the backstop may be positioned adjacent tissue to be penetrated, such that as the penetration member is urged through the tissue along the backstop shaft, the backstop will limit the depth of penetration of the penetration member through the tissue. A method of using this instrument is also provided.

Abstract: The present invention relates to debeaking turkey and chick poultry through non-contact thermal transfer from a source of high frequency heat generating radiation. The present invention directs heat onto the upper beak of a live bird by convection or radiation to thereby affect the continued growth of the beak. Such heating of the bird's upper beak provides a debeaking method which allows the bird's upper beak to stay in place for several days allowing the bird to eat and drink. Heating the portion of the upper beak also allows the poultry tongue and lower beak to be shielded from the heat causing less trauma and injury to the bird. The heat may be directed onto the poultry upper beak by radiation or convection.

Abstract: A safety penetrating instrument for introducing a portal sleeve into an anatomical cavity particularly useful in least invasive surgery includes a safety probe having a distal end configuration cooperating with the sharp distal tip of a penetrating member to protect the tip in an extended position and to expose the tip in a retracted position. The configuration of the distal ends of the penetrating member and the safety probe in the retracted position form a solid, continuous surface tissue penetrating tip for the safety penetrating instrument. The safety probe and penetrating member can be removed from the portal sleeve as a unit or the safety probe can be removed while leaving the penetrating member in place for use in further procedures. The safety probe can carry interchangeable protective bodies on the distal end thereof, the bodies being made of flexible, pliable and preferably resilient materials.

Abstract: A skin seal for making a substantially gas-tight seal with the skin of a patient having a wall with an incision therein comprising a body having proximal and distal extremities and having a flow passage extending from the proximal to the distal extremity. The body has a first outer cylindrical surface extending from the distal extremity toward the proximal extremity and has a uniform diameter. The body also has a second outer tapered surface extending from the first surface toward the proximal extremity and has a gradually increasing diameter. A helical thread is formed on the first and second outer surfaces.
