摘要： A guidewire apparatus for use during percutaneous catheter interventions, such as angioplasty or stent deployment. A protection element comprising a filter or an occluder is mounted near the distal end of a steerable guidewire, which guides a therapeutic catheter. The guidewire apparatus comprises a hollow shaft movably disposed about a core wire and, optionally, a slippery liner interfitted there between. The shaft and core wire control relative displacement of the ends of the protection element, causing transformation of the protection element between a deployed configuration and a collapsed configuration.

摘要： The present invention is a temporary intraluminal filter guidewire for use during interventional procedures, such as angioplasty or stent deployment. A braided filter is mounted near the distal end of a steerable guidewire, which guides a therapeutic catheter. An actuator rod slides over the guidewire and is removably connected to the filter. The rod controls relative displacement of the filter ends, causing transformation of the filter between a deployed configuration and a collapsed configuration. Wire having enhanced radiopacity is included in the filter to provide visualization under fluoroscopy.

摘要： The present invention is a temporary device for capturing and removing embolic material during interventional procedures, such as angioplasty or stent deployment. A self-closing, tubular capture element, which may be either a filter or an occluder, is mounted near the distal end of a guidewire. The guidewire is capable of guiding a therapeutic catheter. Relative displacement of the capture element ends causes transformation of the capture element between a closed configuration and a deployed configuration that spans the vessel to be treated. A latch fixed to the guidewire temporarily retains the capture element in the deployed configuration. A first hollow rod slides over the guidewire to deploy the capture element and engage the capture element proximal end with the latch. A second hollow rod slides over the guidewire to release the latch and close the capture element.

摘要： A medical catheter including a continuous liner defining a guidewire lumen. The liner has a constant inner diameter and a constant outer diameter. A continuous layer is braided over the liner and encapsulated between the liner and a bump layer. The bump layer has a proximal segment, and a bump section. The bump section has a transition zone at the proximal end of the bump section. The proximal segment has a distal end affixed to the proximal end of the bump section. The proximal segment of the bump layer has an outer diameter which is less than the outer diameter of the bump section of the bump layer. The transition zone has an outer diameter which smoothly transitions from the outer diameter of the distal end of the proximal segment of the bump layer to the larger outer diameter at the distal end of the transition zone. The bump layer is encapsulated between the outer jacket layer and the braided layer. The outer jacket layer has a constant outer diameter and an inner diameter conforming to the variable outer diameter of the bump layer. The bump layer is made of a material with a greater flexural modulus than that of the outer jacket layer, such that the flexibility of the catheter is greater at the distal end of the catheter than at the proximal end of the catheter.
摘要翻译：一种医疗导管，其包括限定导丝管腔的连续衬里。内衬具有恒定的内径和恒定的外径。连续层被编织在衬垫上并且封装在衬垫和凸起层之间。凸起层具有近端段和凸起部分。突起部分在凸起部分的近端处具有过渡区域。近端段具有固定到凸起部分的近端的远端。凸块层的近端段的外径小于凸块层的凸块部分的外径。过渡区具有从突起层的近端段的远端的外径平滑地过渡到过渡区的远端处的较大外径的外径。凸起层被封装在外护套层和编织层之间。外护套层具有恒定的外径和与凸起层的可变外径一致的内径。凸起层由具有比外护套层的挠曲模量更大的挠曲模量的材料制成，使得导管的柔性在导管的远端比在导管的近端处更大。
