Abstract: The present solution provides a new social media platform, referred to as a social discovery application, to discover and share with like minded people, such as people in a user's natural communities. The social discovery application allows a user to express their interests and to find people that have the same interests and think like them. For example, the social discovery application may help a user find people most like them at their school, new job, or a new city. The social discovery application includes lots of fun and easy to play games where users express themselves, their interests, and their preferences. The social discovery application then compares their choices to other users' choices in a fun and visual way, and connects users with new potential friends. The social discovery application provides a user a rank order list of people most like them.

Abstract: Drainage system including a ventricular catheter, a drainage catheter, and a positive displacement pump that can function to actively drain CSF from the ventricles of the brain of a patient. Methods of using a drainage system in accordance with the invention are also disclosed, as well as kits.

Abstract: A material fixation system is particularly adapted to improve the tendon-to-bone fixation of hamstring autografts, as well as other soft tissue ACL reconstruction techniques. The system is easy to use, requires no additional accessories, uses only a single drill hole, and can be implanted by one person. Additionally, it replicates the native ACL by compressing the tendons against the aperture of the tibial tunnel, which leads to a shorter graft and increased graft stiffness. It is adapted to accommodate single or double tendon bundle autografts or allografts. It also provides pull out strength measured to be greater than 1000 N.

Abstract: Devices, systems and methods for fixation of tendon to bone are described. An exemplary surgical implant is a modified bone anchor that is able to grasp the tendon and hold it firmly in a bone tunnel. Once deployed, the anchor delivers lateral compression to the tendon, providing direct tendon to bone compression to facilitate healing. The anchor has different versions which allow it to be attached to the tendon prior to insertion into the bone tunnel, or be inserted between tendon arms when the surgical procedure dictates. The resulting tendon to bone compression allows for the firm fixation in a manner markedly simpler than traditional techniques. A modification of this anchor can also allow the anchor to grasp and hold suture. This variation facilitates the technique for knotless rotator cuff repair.

Abstract: An subcutaneously implantable device for delivering Risperidone to a patient includes a pump, a compartment configured to store a pharmaceutical formulation, and a volume of the pharmaceutical formulation loaded in the compartment, the pharmaceutical formulation including Risperidone solvated or suspended in a pharmaceutically acceptable solvent in concentration of at least 50 milligrams per milliliter. The implanted pump may then deliver a therapeutically effective dose of Risperidone to the patient.

Abstract: A mixing syringe and method for using the mixing syringe are provided. The mixing syringe comprises a housing having a first compartment for containing a first component, an outer plunger having a second compartment for containing a second component, and an inner plunger. Prior to use, a seal separates the first and second components. To prepare the mixture, the seal is pierced and the two components are mixed. The mixing syringe and its method of use are particularly suited to applications in which at least one of the mixture components is a relatively highly viscous material.

Abstract: A pivotal fin system, for use with an aquafoil, such as surfboards, body boards, wave skis, sail boards, wake boards and the like, comprising a pot (3) and a fin (2), having a tab (18) extending from the base (17) of the fin (2). The pot (3) has a central slot (11) and is mounted in the board (23) with the opening of the central slot (11) flush with the board (23). The slot (11) has a releasable locking means (6 & 7) therein, and the tab (18) has a connection means (21 & 22), which is releasably engaged by locking means (6 & 7). Preferably the releasable locking means (6 & 7) is a substantially c-shaped clamp, and the connection means (21 & 22) has a recess or recesses (22) behind a bulbous extension (21), which is engaged in the c-shaped clamp, with arms (5) of the c-shaped clamp engaging in the recess or recesses (22).

Abstract: The invention comprises several aspects which are each independently useful or which may be combined in a variety of combinations. One aspect of the invention is placing an atmospheric reference vent at or near the top of a rigid drip chamber for draining CSF from a patient. In the preferred embodiment, the vent is placed on the inside of the drip assembly, immediately next to the CSF. The vent, in another aspect of the invention, is made of a hydrophobic material. In the preferred embodiment, the hydrophilic material is expanded polytetraflouroethylene (e-PTFE). In yet another aspect of the invention, the vent is made of a porous material having a pore size that allows air to readily pass through while preventing CSF from passing through. A preferred embodiment of this aspect includes making the vent of expanded polytetraflouroethylene (e-PTFE) with a pore size ranging from about 0.22 ?m to about 5.0 ?m and more preferable a pore size of about 3 ?m.

Abstract: A pivotable fin system, for use with an aquafoil such as a surfboard, comprising a plug and a fin having a main portion and a tab. The plug mounts in the surfboard, and has a central slot for receiving the tab. The tab has a reverse taper that matches a reverse taper in the central slot. The tab has at least one vertical slot which compresses to allow the tab to be mounted in the central slot, the vertical slot expanding once the tab is fully inserted into the central slot, the tab then securely held in place by the matching reverse tapers of central slot and tab. The tab has at least one tab cut for allowing the main portion of the fin to pivot with respect to the tab, allowing the main portion of the fin to self-align to a position where it reduces drag and cavitation.
