Abstract:
A fluid collection container (1500) includes a vessel (901) and a lid (1300). A splash retarding cover (100) can be attached to a mouth (501) of the vessel (901). The splash retarding cover (100) can include a centrally disposed suspended funnel (101), a collar (102) surrounding the funnel (101), a vessel mounting ring (109), and a plurality of sloping facets (104) circumscribing the collar (102) and sloping outwardly from an outer circumference (105) of the collar (102) and terminating at the vessel mounting ring (109). An optional cache (1904) of coagulant material can be disposed within an interior of the vessel as well.

Abstract:
A telescope design is disclosed that has at least some of its interior facing surfaces configured with corner reflectors, so that a detector operatively coupled to the telescope views itself, instead of those surfaces. The corner reflectors may be on, for example, interior facing surfaces of a conventional baffle appended to the telescope and/or mirror supports or other structures inside the telescope housing that are within the detector's FOV. Likewise, the corner reflectors may be on interior facing surfaces of a baffle that is integrated into the telescope housing. In some such cases, the integrated baffle can be configured as both a baffle and a mirror support. The integrated baffle can be shaped to the F-cone between mirrors of a given telescope design, and/or configured to minimize or otherwise reduce the total obscuration of the baffle to improve the optical throughput.

The corner reflectors may be on, for example, interior facing surfaces of a conventional baffle appended to the telescope and/or minor supports or other structures inside the telescope housing that are within the detector's FOV. Likewise, the corner reflectors may be on interior facing surfaces of a baffle that is integrated into the telescope housing. In some such cases, the integrated baffle can be configured as both a baffle and a mirror support.

Abstract:
A device and method are presented that allow for accurate insertion, positioning and withdrawal of a laser fiber/catheter for minimally invasive laser treatment by utilizing a single mark in the form of a continuous spiral on either a fiber jacket or a catheter (introducer) or both. Viewed from a fixed position the frequency of the appearance of the line can be used to regulate the speed of withdrawal either manually, automatically or through a combination of both, i.e., visual speed feedback and manual withdrawal, automatic speed feedback and manual pullback or automatic feedback and withdrawal. The distal spiral end terminates preferentially in a circumferential loop at some distance back from the distal tip of the catheter or fiber jacket to serve as a safety marker to indicate when to stop lasing during withdrawal to prevent accidental exposure of the patient or attending hospital personnel. Additionally, approaching the distal end, the spiral line can change in color, hue, thickness or some other feature to better provide advanced warning of the approaching fiber end
Abstract:
A device and method for removal of liquid from the downstream side of a membrane or a well, such as a well of a multiwell plate. More specifically, the present invention is directed to a wicking structure, which channels droplets of liquid away from a membrane in communication with a plurality of wells. In the preferred embodiment, the wicking structure is placed in a manifold.
Abstract:
A telescope design having an integrated baffle is disclosed herein. The integrated baffle is configured as both a baffle and a mirror support. The integrated baffle can be shaped to the F-cone between the primary and secondary mirrors of a given telescope design. The baffle design can be adjusted to minimize or otherwise reduce the total obscuration of the baffle to improve the optical throughput. The interior facing surfaces of the integrated baffle can be configured with corner reflectors, so that the detector views itself, instead of the baffle.
Abstract:
An adapter for endoscopic treatments has a fiber constraint device that is set at a desired maximum fiber retraction distance, and provides a physical barrier to prevent excessive fiber retraction into the endoscope. The restricted retraction prevents the fiber from firing within the endoscope, thus avoiding expensive damage to both the endoscope and fiber. This benefits the patient with potentially shorter treatment time and less exposure to anesthesia. The adapter also limits maximum extension of fibers. Limiting maximum extension protects the fiber tip and avoids patient complications. The adapter is securely attached to the optical fiber with a connecting means. When using directionally radiating fiber tips, fiber orientation can be defined and the fiber can be rotated relative to the initial angular position of the fiber tip.

Abstract:
The present invention describes a multi-component handpiece that is both economical and practical for surgical laser treatment. A disposable optical fiber is inserted into a reusable handpiece. The distal end of the optical fiber is protected by a micro-walled protective tube to prevent the disposable fiber from chipping before and during insertion into the handpiece. Once the optical fiber is protected, it is inserted into the handpiece by threading the optical fiber through the cap, body, and cannula of the handpiece until the fiber extends slightly beyond the distal end of the needle. The micro-walled protective tube is removed from the end of the optical fiber, the optical fiber is positioned, and the cap is tightened. The cap and body of the handpiece cooperate to produce a tight friction fit that prevents longitudinal movement of the optical fiber during laser therapy. The tight friction fit holds the optical fiber in place without the use of adhesives, which allows for facilitated removal of the disposable fiber after use. Furthermore, a disposable fiber allows for convenient resterilization of the handpiece to eliminate the transmission of disease from one patient to the next without having to dispose of the entire handpiece following every laser procedure.
