摘要:
Methods and apparatus for intraocular brachytherapy are disclosed in which a cannula is introduced into the eye for delivery of radiation to a target tissue. Techniques for properly locating the cannula with respect to the target tissue, for protecting non-target tissue, for regulating heat generated by x-ray emitters, and for combining therapies are disclosed.
摘要:
A method for performing intraocular brachytherapy and an apparatus for performing the same is disclosed. The apparatus preferably comprises a hand-held delivery device that advances a radiation source into an associated cannula or probe that is positioned adjacent the target tissue. The handpiece provides for shielded storage of the radiation source when retracted from the cannula and includes a slider mechanism for advancing and retracting the radiation source. The radiation source is mounted to a wire that has a flexible distal end and a relatively stiffer proximal end. A positioning system for the cannula is also disclosed.

Method and apparatus are disclosed employing ionizing radiation for forming lines of ablation or lesions in cardiac tissue to treat atrial fibrillation or other electrophysiological problems with the heart. The apparatus may include a catheter in which the radiation source is advanced hydraulically after the catheter is in place within the heart. Various fixation devices are also disclosed for fixing the location of the catheter within the heart.

Methods and apparatus are disclosed for an improved barriers and fence systems, including a supplemental panel for fences or gates or the like, alone and or in combination with such pre-existing fences/gates or similar elements. The supplemental panel can be fabricated using relatively cost-effective materials and processes, and effectively reduces the space or gaps between generally vertical pickets and/or horizontal elements on an existing fence/gate/etc., and is readily mounted and racked into generally parallel alignment with those existing generally vertical pickets, and the mounting can be independent of the racking function/structure (such as by bending the added vertical picket elements at a selected/provided location on each added picket). The added vertical elements can be low-visibility and selectively spaced laterally to fit aesthetically between the existing pickets.
摘要:
A picket fence and rail mounting system that is easily transformable by the consumer into a variety of aesthetic styles is provided. The system comprises at least an upper and a lower elongate rail. Each rail has a hollow interior defining a substantially I-shaped cross-section including at least a first slot and a second slot. A plurality of pickets are transversely slidable through openings in an upper surface of the rails and a channel in a lower surface. The pickets each have at least a first notch or indentation near a first end and a second notch or indentation near a second end. The distance from the first end to the first notch or indentation is preferably shorter than the distance from the second end to the second notch or indentation. An elongate retaining rod slidable within at least one rail cooperates with a notch or indentation on each picket to secure the picket to the rail. Rather than the retaining rod, spring clips, threaded fasteners or the like may cooperate with a hole in each picket to secure the picket to the rail. The pickets are invertible, such that they extend a distance x or a distance y above the upper rail depending upon whether the first or second notch or indentation or hole engages the retaining rod or other fastening member. Finials and decorative inserts may be secured to the fence to provide more aesthetic styles. Further, the upper rail is invertible, wherein a smooth cap may be secured to the upwardly facing surface of the upper rail, providing the fence with a smooth upper end having no protruding pickets.

A wound clotting device is disclosed comprising a clotting device for dispensing a clotting agent onto a selected location in a patient while being retained adjacent to that location, comprising a tube having a proximal end portion and a distal end portion; means defining an inflation lumen in said tube extending between said proximal and distal end portions; inflatable retention means carried by said tube at said distal end portion for retaining said distal end at a selected location within the body of a living patient, said retention means being in fluid communication with said inflation lumen; means defining a second lumen in said tube extending between said proximal and distal end portions; means for receiving a quantity of clotting agent located within said second lumen; and means disposed within said second lumen for dispensing said clotting agent from said distal end of said second lumen to deposit said clotting agent at said selected location within a patient. A method for using such clotting device is also disclosed.

Fence apparatus and related methods for making a fence panel and for connecting the panel to other panels and post elements to form a modular type fence are disclosed. These include a generally planar section of fencing material formed from spaced-apart wires, and the related brackets and posts of the system providing simplified installation, removal, handling, and storage of the fence components.
