摘要:
An applicator device for dispensing and/or applying an adhesive material comprises a body portion comprising a closed proximal end and an open distal end providing a cavity. The cavity is sized to accept a frangible container having a polymerizable adhesive material. At least one breaking member integral with the body portion and having a surrounding gap is at least partially deflectable into the cavity and each breaking member has a first engagement member. An annular housing movable with respect to the body portion has a second engagement member complementary with the first engagement member, the first and the second engagement member being cooperatively engageable with each other. When the annular housing is moved relative to the body portion from a first position where the first and the second engagement member are not cooperatively engaged with each other, to a second position where the first and the second engagement member are cooperatively engaged with each other, at least a portion of the at least one breakable member is deflected into the cavity.

An applicator device for dispensing a polymerizable adhesive material comprising a body portion comprising a closed proximal end and an open distal end providing a cavity sized to accept a frangible container having a polymerizable adhesive material; at least one breaking member at least partially deflectable into the cavity; an annular housing movable with respect to the body portion; and a reservoir secured to the open distal end of the body portion, the reservoir further comprising an applicator; wherein the annular housing is movable relative to the body portion from a first position to a second position to deflect at least a portion of the breaking member into the cavity.
摘要:
A molding process includes flowing a polymer melt into the cavity of a mold which includes a core pin. After the mold is filled and skin layers of solidified polymer have formed adjacent the mold wall and core pin wall, the core pin is spun transversely to the direction of polymer melt flow. The invention includes hollow articles of improved mechanical properties made by the process.

A bioabsorbable suture anchor for anchoring soft tissue to a bone is provided. The suture anchor is configured to toggle and anchor itself inside a bone cavity of a small joint. The anchor comprises an elongate body defined by a longitudinal axis, a first, leading end and a second, trailing end. The elongate body also has two opposed surfaces between the first and second ends, and a plurality of sidewalls extending between the two opposed surfaces. Extending from one of the sidewalls is a flared portion that is formed on the second end of the elongate body. The flared portion is adapted to engage and anchor into bone tissue upon toggling. A suture channel extends between the two opposed surfaces. The suture channel is formed in the elongate body for passage of a suture strand therethrough, such that pulling on an attached suture strand effects toggling of the anchor inside a bone cavity.
摘要:
Gel formulations including a polydimethylsiloxane-polyethyleneoxide copolymer gelled with dibenzylidine sorbitol in the presence of water or alcohol. The gel formulations are useful for facilitating the separation of blood serum or plasma from the cellular portion of blood or as a thermoreversible shear sensitive substance.
