An occlusive implant system may include a catheter having a lumen extending therethrough, a core wire slidably and rotatably disposed within the lumen, the core wire having a threaded member disposed at a distal end, and a medical implant having an expandable frame, an occlusive element disposed on the frame, and a threaded insert coupled to a proximal portion of the frame, wherein the threaded member is removably coupled to the threaded insert.

Retrieval wire centering device

An occlusive medical implant having a frame actuatable between a collapsed delivery configuration and an expanded implanted configuration, the frame including a generally tubular portion with a threaded insert configured to removably attach to a threaded distal end of a core wire; an occlusive element disposed on the frame; where a proximal portion of the occlusive element and the proximalmost extent of the threaded insert are substantially coplanar with a plane defined by three or more proximalmost extents of the frame in the expanded implanted configuration.

A left atrial appendage closure implant may include a support frame including a first bend extending from a proximal collar to a second bend, a first segment extending from the second bend to a third bend, a second segment extending from the third bend to a fourth bend, and a third segment extending from the fourth bend to a distal collar, wherein the support frame is actuatable from a first constrained position to a second flowering position to a third mid-deployment position to a fourth unconstrained position. An implant may include a self-expanding support frame having a circumference and a central longitudinal axis, a membrane disposed over at least a portion of the support frame, and a plurality of anchors arranged into a first row and a second row such that the first row and the second row form a staggered pattern about the circumference of the support frame.

A system and method for manufacturing and/or reconditioning side frames and bolsters for railway cars includes at least one robot adapted to access positions along the length of the part. A map of the part dimensions, which may be obtained by a probe or scanner on the robot(s), allows a processor to determine where welding and machining are required to meet certain dimensional tolerances, leveraging novel reference surfaces on the part which cannot be leveraged using conventional gauges. The robot(s) may locate and mount welding and material removal tools to carry out the welding and material removal operations determined by the processor.

Automated machining and welding of railway car parts

The invention relates to a railway car truck incorporating an interconnection between a side frame and a bearing adapter. The bearing adapter may receive a reduced coefficient of friction surface member in a recess on a top surface of the bearing adapter, facilitating a reduced lateral spring rate of the wheelset. Alternatively, or in combination, an adapter plate is received in the pedestal jaw on the bearing adapter to retain the reduced coefficient of friction surface member above or below the adapter plate. The adapter plate may be provided with surfaces about perpendicular to the longitudinal and lateral axes of the side frame to support elastomeric members, which may provide different longitudinal and lateral spring rates in response to a load applied to the truck.

An implantable medical device for insertion in the left atrial appendage includes a cap coupled to a frame. The cap constrains movement of the legs of the frame during collapse and expansion of the device, such that the device can be deployed, recalled and redeployed without the device being damaged or the legs of the frame getting tangled.

Device and method for occluding the left atrial appendage

An occlusion device (e.g., for treatment of the left atrial appendage) includes a framework and a biocompatible covering disposed over at least a part of the framework. The framework may include a proximal portion, a middle portion, and a distal portion, wherein: the proximal portion includes a first hub that has a fixed first diameter; the middle portion has a second diameter and includes a plurality of beams extending from the first hub to a distal portion, wherein each of the plurality of beams is connected to an adjacent beam by a first circumferentially extending column of strut pairs; and the distal portion has a third diameter. In one or more embodiments, the framework includes improved circumferential strength and minimizes foreshortening.

Occlusion device

A medical device including a medical device body that includes a first support structure, the medical device further comprising a first fixation anchor that includes a first anchor body extending between a first end and an opposing second end, and a hook portion extending from the first end, wherein the first anchor body engages the first support structure, and wherein the first fixation anchor is fabricated separate and apart from the medical device body. A method of making a medical device is disclosed.

Medical devices having fixation anchor

The disclosure pertains to a handle assembly for a left atrial appendage occlusion device delivery system and methods of use therefor. The handle assembly includes a leadscrew mechanism for smooth, low backlash control of a delivery catheter for the left atrial appendage occlusion device and manipulation segments which allow one hand operation of the handle assembly.
