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 system comprising a guiding catheter having an inflation lumen. The inflation lumen extends within a handle and a shaft of the guiding catheter. An inflatable sleeve has a proximal end and a distal end, with the ends attached to the guiding catheter. A sealed interior portion of the inflatable sleeve is bounded by the inflatable sleeve and the shaft of the guiding catheter, and in fluid communication with a distal port of the inflation lumen. The system further comprises a delivery catheter defining a delivery lumen and configured for sliding engagement within the guide lumen of the guiding catheter.

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: 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: 导管具有限定输送腔的轴，例如，以递送细长的医疗装置; 导管的近端部分包括密封区部分，手柄部分和近端口部分。 近端口部分的相对薄的壁部分在密封区部分和限定输送腔的近端开口的周边的一部分的近端边缘之间延伸。 手柄部分从密封区域部分横向伸出，大致与相对薄的壁部分相对。 导管的膨胀子组件包括顺应性套筒构件和从套筒构件沿着轴向近侧延伸并且形成在手柄部分中的连接器端口的充气腔。 膨胀腔可以通过将管的一部分熔合到轴并且将手柄部分围绕管的另一部分成型而形成。
