Abstract: In some embodiments, an apparatus includes an elongated member, an expandable member coupled to the elongated member, and an outer sheath. The outer sheath, which can be constructed from a different material than the expandable member, is disposed about the expandable member such that an outer surface of the expandable member is in discontinuous contact with an inner surface of the outer sheath. The expandable member and the outer sheath are configured to cooperatively displace a bone structure when moving between a collapsed configuration and an expanded configuration.

Abstract: An apparatus includes an expandable member and an elongate assembly. The expandable member is configured to displace a first portion of a bone structure relative to a second portion of the bone structure when moved from a collapsed configuration to an expanded configuration. The elongate assembly includes a shaft and an elongated member disposed with a lumen defined by the shaft. A proximal end portion of the expandable member is coupled to a distal end portion of the shaft such that the proximal end portion of the expandable member does not rotate relative to the distal end portion of the shaft when at least a portion of the expandable member is twisted about the elongated member through at least four revolutions.

Abstract: A method includes moving an actuator from a first position to a second position such that a first shaft is rotatable relative to a second shaft. The second shaft is disposed within the first shaft and coupled to an expandable member. The actuator is moved from the second position to the first position such that the second shaft is rotatable relative to the first shaft through a plurality of discrete increments.

Abstract: This invention relates to devices for inserting expandable structures, such as medical balloons, into interior regions of a human or animal body, as well as methods for their use. The insertion devices described herein are capable of directionally guiding and/or inhibiting expansion of an expandable structure within an interior region of an animal or human body to create optimally placed cavities for repair, augmentation and/or treatment of fractured and/or diseased bone.

Abstract: A heat sink includes a heat conductive portion, a plurality of fins and at least one connecting portion. The fins and connecting portion are disposed around the heat conductive portion. The connecting portion is disposed between the fins and has a fixed part. The fixed part is disposed at one side of the connecting portion and is used for connecting with a fastener.

Abstract: An apparatus includes a support member and a knob, each having an engagement portion. The support member is coupled to a shaft of a catheter assembly. The knob is configured to engage a stylet of the catheter assembly. The knob is configured to rotate relative to the support member through multiple discrete increments when the engagement portion of the knob is engaged with the engagement portion of the support member. Each discrete increment can be, for example, less than one revolution (e.g., thirty degrees of rotation).

Abstract: A heat sink has a heat-dissipating portion and a contact portion for contacting an electric device generating heat. The diameter of the contact portion is smaller than that of the heat-dissipating portion. The heat-dissipating portion has a plurality of fins. The contact portion is disposed on a bottom surface of the heat-dissipating and formed with the heat-dissipating portion as a single unitary member. The contact portion includes a first axial cross section and a second axial cross section. The first axial cross section is away from the heat-dissipating portion, and the second axial cross section is near the heat-dissipating portion. The diameter of the first axial cross section is larger than that of the second axial cross section.

Abstract: A heat dissipating module has a fan and at least one heat sink contacting with a heat source. The fan has an impeller and a housing. The housing has a base for supporting the impeller, at least one rib extending from the edge of the base to the backward direction of the center of the base, at least one sidewall, an annular wall connecting with the rib and/or the sidewall, at least one protrusion axially protruding from the annular wall and/or the sidewall, at least one securing member disposed on the end of the protrusion, and at least one fastener disposed in the securing member. The base, the rib, the sidewall, the annular wall, the protrusion, and the securing member are integrally formed as a single piece. The protrusion has at least one block structure for fixing the heat sink to the housing.

Abstract: A device and method for creating a connection with the left ventricle of a heart are provided. A seal member capable of moving between a folded position and an open position is attached to the end of a conduit. An introducer capable of moving between a first and second position allows for the expansion of the seal member into an open position. A clamp component is positioned outside of the heart to provide an axial clamping force with the wall of the heart so that a seal is created between the seal member and the wall of the heart.

Abstract: A heat sink includes a plurality of fins, each of which includes a first vent and a first baffle. Each baffle is extended at one side of the first vent, and each of the first vents of the fins is located corresponding to the first vent of an adjacent fin. The heat sink further has a base, on which the fins are installed in parallel.

Abstract: A heat dissipating assembly includes a fan and a composite heat dissipating structure. The composite heat dissipating structure includes a first heat sink and a second heat sink disposed adjacent to the first heat sink. The first and the second heat sinks include a plurality of first fins and a plurality of second fins respectively. The arrangement of the first fins is different from that of the second fins so as to flexibly regulate heat dissipation. Also, the fan dissipates heat accumulated in the composite heat dissipating structure and facilitates heat transmitted by the composite heat dissipating structure to dissipate more efficiently.
