Abstract: A catheter has a shaft that defines a delivery lumen, for example, to deliver an elongate medical device therethrough; a proximal section of the catheter includes a seal zone portion, a handle portion and a proximal port portion. A relatively thin wall section of the proximal port portion extends between the seal zone portion and a proximal edge that defines part of a perimeter of a proximal opening of the delivery lumen. The handle portion projects laterally from the seal zone portion, generally opposite the relatively thin wall section. An inflation subassembly of the catheter includes a compliant sleeve member and an inflation lumen extending from the sleeve member, proximally along the shaft, and into a connector port formed in the handle portion. The inflation lumen may be formed by fusing a section of a tube to the shaft and molding the handle portion around another section of the tube.

Abstract: An operator advances a delivery catheter through a guiding catheter, after positioning an inflatable sleeve of the guiding catheter in proximity to a target implant site on an epicardial surface. By inflating the positioned sleeve, the operator displaces the epicardial surface to create a gap that accommodates a reach of the delivery catheter. With the delivery catheter extending distally from the guiding catheter, the operator can activate the reach of the delivery catheter within the gap, and then advance the lead out through a distal-most opening of the delivery catheter. The reach may orient a fixation member of the advanced lead relative to the epicardial surface so the operator can secure the lead to the surface. The sleeve of the guiding catheter is preferably non-compliant and has a maximum diameter of at least twice the reach of the delivery catheter, when inflated.

Abstract: A medical access tool includes a needle member extending along a longitudinal axis, and a coiled wire extending around the axis. An inner surface of the coiled wire, along a proximal segment thereof, is spaced radially apart from an outer surface of the needle member, and a distal segment of the coiled wire extends distally to a tissue-engaging tip of the coiled wire, a piercing distal tip of the needle member being recessed proximally from the tissue-engaging tip at a fixed distance. An operator may rotate the coiled wire to engage tissue, for example, that of a pericardial sac or a diaphragmatic attachment, which then travels proximally along the coiled wire and into contact with the needle member's distal tip, to be pierced through thereby. At least one lumen of the needle member provides a passageway through which the operator may advance a guide wire and/or inject a fluid.
Abstract translation: 医疗通道工具包括沿着纵向轴线延伸的针状构件和围绕该轴线延伸的螺旋线。 螺旋线的沿其近端段的内表面与针构件的外表面径向分开，并且螺旋线的远端段向远侧延伸到线圈的组织接合尖端，穿孔 针构件的远侧末端在固定距离处从组织接合末端向近侧凹陷。 操作人员可旋转卷绕的线以接合组织，例如心包囊或隔膜附件的组织，其然后沿着螺旋线向近端行进并与针构件的远侧尖端接触，从而被刺穿。 针构件的至少一个内腔提供通道，操作者可以通过该通道推进导丝和/或注入流体。
