摘要:
A medical device for renal denervation may include a catheter shaft including an outer shaft having a lumen formed therein and an inner shaft extending within the lumen of the outer shaft. The catheter may further include an expandable member having a proximal region coupled to a distal region of the outer shaft, and a distal region of the expandable member may be coupled to a distal region of the inner shaft. In some embodiments, one or more active electrodes may be disposed on an exterior surface of the expandable member and capable of providing the renal denervation treatment. In some embodiments, the inner shaft may be rotatable in relation to the outer shaft and/or the outer shaft may be rotatable in relation to the inner shaft.
摘要:
An embolic coil delivery assembly is disclosed. The delivery system may include a tubular member having a distal portion, a proximal portion and a lumen extending therein. The system may further include a tip member secured to the tubular member. The tip member may include a distal portion and a bonding portion. The bonding portion may include a bonding surface. The system may also include an embolic coil releasably disposed within the distal portion of the tip member. The distal portion of the tubular member may extend over the bonding portion of the tip member. The bonding surface may be configured to mechanically interlock with the tubular member.
