  • Publication number: 20230366085
    Abstract: A tray assembly comprises a plurality of trays. Each of the plurality of trays comprises a first tray portion and a second tray portion which are couplable together by a retainer and which are engageable with a cam member. Depending on the orientation of the cam member, each of the plurality of trays of the tray assembly is configurable between an expanded configuration and a collapsed configuration.

  • Publication number: 20230298909
    Abstract: Systems and methods for controlling precursor delivery. The systems and methods may comprise a precursor delivery vessel in fluid communication with a gas flow line. The precursor delivery vessel may comprise at least one tray containing a vaporizable precursor. An amount of thermal energy may be supplied to the at least one tray in an amount sufficient to vaporize the vaporizable precursor. The vaporized precursor may be dispensed from the precursor delivery vessel to the gas flow line. The amount of thermal energy supplied to the at least one tray may be adjusted sufficient to maintain a pressure of the vaporized precursor, in the gas flow line, within a pressure range.

  • Publication number: 20080091277
    Abstract: A prosthesis for repairing a hernia includes an adhesion-resistant biodegradable region and an opposing tissue-ingrowth biodegradable region. When the prosthesis is implanted into the patient, the adhesion-resistant biodegradable region covers a fascial defect of the hernia, and the tissue-ingrowth biodegradable region is located above the adhesion-resistant biodegradable region while being exposed substantially only to the host's subcutaneous tissue layer. This orientation allows the tissue-ingrowth biodegradable region to become firmly incorporated with the host's body tissue. The adhesion-resistant biodegradable region faces the internal organs and decreases the incidence of adhesions and/or bowel obstruction.

  • Publication number: 20080063686
    Abstract: Resorbable lactide polymer thin membranes are disclosed. The thin membranes are constructed of polylactide resorbable polymers, which are engineered to be absorbed into the body relatively slowly over time in order to reduce potential negative side effects. The membranes are formed to have very thin thicknesses, for example, thicknesses between about 0.010 mm and about 0.300 mm. The membranes can be extruded from polylactide polymers having a relatively high viscosity property, can be preshaped with relatively thick portions, and can be stored in sterile packages.

  • Publication number: 20070154525
    Abstract: An anti-adhesion membrane is placed onto an implant introduced into a surgical site of a patient to prevent post-surgical adhesions between the implant and surrounding tissue. The implant may comprise either biological material, such as a transplanted organ, or non-biological material such as a medical device. The membrane may be applied in a variety of ways. In one example, a membrane according to the present invention is shrink-wrapped around a pace-maker. In another example, a breast implant is spray-coated or dipped with the membrane material.

  • Patent number: 5547199
    Abstract: A method of playing a sentence forming game is disclosed which consists of a plurality of cards with a plurality of sentences (12) known as sentence cards or sentence means (10), a plurality of cards with a plurality of pictorial elements (16) known as picture cards or picture means (14), and a plurality of rewards or scoring means (36). Players chose a sentence (12) from sentence card or sentence means (10) to form by finding relationships between words in sentence (12) on sentence card or sentence means (10) and pictorial elements (16) on picture cards or picture means (14). These relationships are subjectively judged by the other players. Players receive rewards and/or scoring means (36) based on if their explanations are subjectively judged by the other players to be interesting, creative, and/or entertaining.

  • Patent number: 5333878
    Abstract: A maze type board game comprising a game board (17) having a plurality of maze areas (22) and segments interconnected between maze areas comprising a plurality of spaces which include: movement spaces (19), starting spaces (20) and transport spaces (18), at least one separate movable search piece (16) for each player, and a plurality of maze walls (12) for disposition on the game board, the spaces and maze walls having cooperative dimensions such that a plurality of maze walls are required to define a maze on the game board. The game is played in an attempt by one player to find the marked orb(s) (15) hidden among decoy orb(s) (14) of another player while the player, whose marked orb(s) is/are being searched for, places maze walls to delay or prevent other player(s) from finding the marked orb(s) thus forming a maze that must have at least one entrance and path leading to every marked orb in that maze area from the interconnected segments between the maze areas.
