摘要： A medical device and method are provided for accessing a side branch in an artery. The device includes a catheter having a sidewall, an internal lumen, and a side port formed through the sidewall. A perforating guide wire has a proximal portion within the internal lumen and a distal portion arranged to be movable out of the side port. The guide wire can be delivered through the side port to a side branch artery when the catheter is deployed to a location with the side port aligned with the side branch artery. In another embodiment, the catheter has inner and outer telescoping tubes with offset exit ports formed therein. The telescoping tubes can be used to change the degree of deflection of the perforating guide wire by changing the relative positions of the offset exit ports.

摘要： A catheter and method of making a catheter are disclosed in which the catheter is highly flexible and yet resistant to crushing and kinking. The catheter is made by applying rings of hard polymer material along the tubular shaft as the catheter is manufactured. The catheter thus has a plurality of hard polymer rings formed at spaced locations along its length, and soft segments between the hard polymer rings that allow the catheter to remain very flexible. The hard polymer rings improve the radial strength of the catheter and make the catheter resistant to crushing and kinking.

摘要： An apparatus and method for nonextrusion manufacturing of catheters that can be used to produce catheters having a simple or complex configuration. A polymer material in a particulate preform is applied in a layer over an outer surface of a core member. By applying the polymer material in a particulate preform, a composition of the polymer material can be varied continuously as it is being applied to provide a variable hardness over the length of the catheter. A fibrous reinforcement can be used having a constant or variable pitch and a constant or variable number of fibers and fiber types. Sensors can be easily placed in a wall of the catheter as the catheter is being fabricated, thereby allowing more sensors to be used without placing conductors in the lumen of the catheter. Deflection passages can be provided in a wall of the catheter for inserting a wire to deflect the catheter. The polymer material can be heated into molten form as it is being applied, or the core mandrel or liner can be heated to cause the polymer material to consolidate upon impact. A mandrel in the preferred embodiment is rotated about its longitudinal axis while a spray head and filament winding head traverse the length of the mandrel and apply polymer material and filament, respectively. Other arrangements can also be used, including a spray head and filament winding head that rotate about a continuous core mandrel, and a fluidized bed or other container into which a heated core mandrel is immersed. A plurality of mandrels can be placed side-by-side to form a multiple lumen tubing.

摘要： An apparatus and method for curving a catheter after deployment include a catheter having a primary lumen, a secondary lumen, and a resilient fiber contained within the secondary lumen. The resilient fiber and the secondary lumen have corresponding, preformed curve shapes when the catheter is in a straight, unstressed condition. The resilient fiber is slidable within the secondary lumen to create a desired curve shape in the catheter as the curved portion of the resilient fiber slides into an originally straight portion of the secondary lumen. In another embodiment, the preformed curve shape of the resilient fiber is held in a straight condition within a stiff, marker ring segment of the catheter until after the catheter is deployed. Once deployed, the resilient fiber is slid out of the marker ring segment, and the preformed curve shape of the resilient fiber creates a corresponding curve shape in the catheter.

摘要： A method of making catheters is disclosed in which the wall of the catheter has a porous structure for carrying additional agents, such as therapeutic agents, diagnostic agents and/or device enhancements. The method includes applying a base polymer material and an inert material over the outer surface of a core, and curing or consolidating the base polymer material to form a catheter having a porous polymer layer with the inert material contained within the pores thereof. The inert material can be applied with the base polymer material or in a separate step after the base polymer material has been partially cured or consolidated to form the porous polymer layer. Additional agents can be mixed with the inert material before it is applied to the catheter, or can be applied to the porous polymer layer of the catheter in a separate step after the inert material is removed therefrom.

摘要： A bumper assembly for attachment to a post has a hollow bumper member with an internal bore that fits over a post and allows the bumper member to rotate. A protective liner is provided between the bumper member and the post and has an internal bore that fits around the post and an external wear surface that fits within and rotatably supports the bumper member. A retaining ring can be secured to the post to hold the bumper assembly in place vertically. Alternatively, the hollow bumper member can be provided with end faces that interact with the upper and lower surfaces of a protective liner positioned within the hollow bumper member to hold the bumper assembly in place vertically. The components of the bumper assembly can be split along one side or provided as two separate halves attachable together to facilitate attachment to posts that are restrained on both ends.

摘要： A catheter having a fibrous reinforcement is formed by anchoring a filament at a proximal end of a core member, and winding the filament onto the core member continuously from the proximal end to the distal end of the core member and then back to the proximal end to form a first fibrous layer. The filament is wound with a constant or variable pitch along the length of the core member. Additional fibrous layers can be applied by continuously winding a filament over the first fibrous layer from the proximal end to the distal end or to an intermediate position along the core member and then back to the proximal end. The additional layers can extend to different distal positions to form a catheter having a tapering profile. In alternative embodiments, catheters are formed by winding a group of filaments onto the core member simultaneously.
