摘要:
A sheath for delivering and/or retrieving an embolic protection filtering devices. The sheath may include a proximal portion and a distal portion. The distal portion may be expandable and may include a bulbous member or region. Additionally, the sheath may include structural support in a number of different forms.
摘要:
A percutaneous medical device that may include a stopper having a first end, a second end and a lumen therebetween, the stopper having first state where the lumen has a first cross-sectional area and a second state where the lumen has a second cross-sectional area less than the first cross-sectional area, the stopper having a slit between the first end and the second end when in the first state, the slit defining a gap, the stopper when in the second state having no bias to move to the first state at body temperature, the stopper having a distance of less than 3 cm between the first end and the second end and apparatus and methods of use pertaining thereto.
摘要:
Guidewire with an improved distal end. A guidewire with an improved distal end may include a core wire, a solder tip disposed at a distal end of the core wire, a radiopaque inner coil coupled to the distal end of the core wire, an outer coil disposed along the length of the core wire, and a distal hub coupled to the core wire and disposed proximate a distal end of the inner coil.
摘要:
Devices, systems, and methods provide for intravascular or extravascular delivery of renal denervation therapy and/or renal control stimulation therapy. Wireless vascular thermal transfer apparatuses and methods provide for one or both of production of current densities sufficient to ablate renal nerves and terminate renal sympathetic nerve activity, and production of current densities sufficient to induce endothelium dependent vasodilation of the renal artery bed. A common apparatus may be used for both renal ablation and control of renal function locally after renal denervation.

摘要:
An embolic protection filter assembly and method of assessing the size of an intravascular lesion. The filter assembly may include an elongate sheath having one or more marker members coupled thereto. The assembly may also include an elongate shaft having a filter coupled thereto.
