20080306491SINGLE STAGE HEMOSTASIS CLIPPING DEVICE - A tissue clipping apparatus comprises a clip including a proximal end received within a capsule. The clip includes a clip locking member biased to engage a first locking structure of the capsule to lock the clip in the capsule in a closed configuration. The apparatus also comprises a tension member releasably coupling the clip to a proximal end of the device which, during use, remains accessible to a user. The tension member is coupled to the clip by a joint designed to release when subject to a predetermined load to separate the clip from the device, release of the joint releasing the locking member to engage the first locking structure.12-11-2008
20100022913Forceps and collection assembly with accompanying mechanisms and related methods of use - The invention includes a forceps and collection assembly for acquiring and storing a plurality of tissue samples in a single pass, and accompanying mechanisms for use with the forceps and collection assembly. The accompanying mechanisms include an endoscope working channel cap assembly configured to minimize compression of a pouch of the forceps and collection assembly as it traverses a seal of the cap assembly, and a flush adapter configured to be coupled to the pouch so as to assist in removing tissue samples in the pouch by flowing fluid through the pouch.01-28-2010
20110046651MULTIFUNCTIONAL CORE FOR TWO-PIECE HEMOSTASIS CLIP - A device includes a clip including first and second arms distal ends of which are biased apart and a core member including first and second portions connected to one another via a frangible link. The first portion includes a first protrusion for engaging a cut-out in the first arm. The frangible link is fractured when subjected to a load of at least a predetermined level deploying the clip. The device also includes a capsule slidably housing the core member and a proximal portion of the clip.02-24-2011
20110071432Fine Needle Aspiration Device with Distal Anchor - A device for capturing a tissue sample from within a body comprises a needle slidably comprising a needle lumen extending therethrough to a needle opening in the distal end and a stylet slidably received in the needle lumen for movement between an extended position in which a tissue penetrating distal tip of the stylet extends out of the needle opening to penetrate target tissue and a retracted position in which the distal tip of the stylet is received within the needle opening to substantially seal the needle lumen. The stylet further comprises an anchoring feature located proximally of the tissue penetrating distal tip. The anchoring feature comprises a first gripping member including a first proximal facing abutting surface adjacent to a first tissue receiving gap. Movement of the stylet distally out of the needle lumen brings the first gripping member into engagement with surrounding tissue to anchor the stylet at a desired position within the body.03-24-2011

20100147695Multi-cell Masks and Methods and Apparatus for Using Such Masks To Form Three-Dimensional Structures - Multilayer structures are electrochemically fabricated via depositions of one or more materials in a plurality of overlaying and adhered layers. Selectivity of deposition is obtained via a multi-cell controllable mask. Alternatively, net selective deposition is obtained via a blanket deposition and a selective removal of material via a multi-cell mask. Individual cells of the mask may contain electrodes comprising depositable material or electrodes capable of receiving etched material from a substrate. Alternatively, individual cells may include passages that allow or inhibit ion flow between a substrate and an external electrode and that include electrodes or other control elements that can be used to selectively allow or inhibit ion flow and thus inhibit significant deposition or etching. Single cell masks having a cell size that is smaller or equal to the desired deposition resolution may also be used to form structures.06-17-2010
20100193366Method For Electrochemical Fabrication - An electroplating method that includes: a) contacting a first substrate with a first article, which includes a substrate and a conformable mask disposed in a pattern on the substrate; b) electroplating a first metal from a source of metal ions onto the first substrate in a first pattern, the first pattern corresponding to the complement of the conformable mask pattern; and c) removing the first article from the first substrate, is disclosed. Electroplating articles and electroplating apparatus are also disclosed.08-05-2010
20100264037Method for Electrochemical Fabrication - An electroplating method that includes: a) contacting a first substrate with a first article, which includes a substrate and a conformable mask disposed in a pattern on the substrate; b) electroplating a first metal from a source of metal ions onto the first substrate in a first pattern, the first pattern corresponding to the complement of the conformable mask pattern; and c) removing the first article from the first substrate, is disclosed. Electroplating articles and electroplating apparatus are also disclosed.10-21-2010
20110132767Multi-Layer, Multi-Material Fabrication Methods for Producing Micro-Scale and Millimeter-Scale Devices with Enhanced Electrical and/or Mechanical Properties - Some embodiments of the invention are directed to electrochemical fabrication methods for forming structures or devices (e.g. microprobes for use in die level testing of semiconductor devices) from a core material and a shell or coating material that partially coats the surface of the structure. Other embodiments are directed to electrochemical fabrication methods for producing structures or devices (e.g. microprobes) from a core material and a shell or coating material that completely coats the surface of each layer from which the probe is formed including interlayer regions. Additional embodiments of the invention are directed to electrochemical fabrication methods for forming structures or devices (e.g. microprobes) from a core material and a shell or coating material wherein the coating material is located around each layer of the structure without locating the coating material in inter-layer regions. Each of these groups of embodiments incorporate both the core material and the coating material during the formation of each layer and each layer is also formed with a sacrificial material that is removed after formation of all layers of the structure. In some embodiments the core material may be a genuine structural material while in others it may be only a functional structural material (i.e. a material that would be removed with sacrificial material if it were accessible by an etchant during removal of sacrificial material.06-09-2011

20110147223Methods of Forming Three-Dimensional Structures Having Reduced Stress and/or Curvature - Electrochemical fabrication processes and apparatus for producing single layer or multi-layer structures where each layer includes the deposition of at least two materials and wherein the formation of at least some layers includes operations for reducing stress and/or curvature distortion when the structure is released from a sacrificial material which surrounded it during formation and possibly when released from a substrate on which it was formed. Six primary groups of embodiments are presented which are divide into eleven primary embodiments. Some embodiments attempt to remove stress to minimize distortion while others attempt to balance stress to minimize distortion.06-23-2011
