摘要： A device and method for accessing a pericardial space of the heart includes a shaft having a cavity at a distal end, a suction lumen terminating in a distal port within the cavity and a hollow needle having a distal tip extending into the cavity. The cavity may be a recess in the shaft into which the distal tip of the needle fixedly protrudes. In other embodiments, the cavity is formed by an inflatable member positioned at the distal end of the shaft and the needle is slidable relative to the shaft. Suction is applied at the cavity to draw a pericardial bleb. The needle pierces the pericardial bleb for accessing the pericardial space and also facilitates delivery of payloads into the pericardial space.

摘要： The present invention is a medical assembly comprising an elongated flexible medical device, such as a cardiac lead, and a torquing member, such as a stylet, slidably receivable inside the medical device. The device and member are coupled at their distal ends by a corresponding set of opposing curves. This coupling allows more precise rotational control of the assembly when it is manipulated at its proximal end. In one embodiment, the assembly has a open curvature at its distal end. In another embodiment, the distal end has a closed curvature.

摘要： An improved guidewire for assisting in implantation of a cardiac lead includes three sections. The most distal zone is sufficiently floppy to prevent trauma to the vessel walls through which the guidewire and lead are inserted. An intermediate zone is generally stiffer and has a cross-section less than or equal to the cross-section of the distal zone. The third zone is stiffer yet and is joined to the intermediate zone by a shoulder. The shoulder cooperates with protrusions on the lead to transfer forces between the guidewire and lead. A removal wire having temporary locking device to lock the removal wire to the lead is employed to remove the guide catheter without moving the lead from its desired location. Lubricious coatings are also provided to reduce friction between the lead and guidewire.

摘要： According to one embodiment, the present invention includes an elongate implantable medical lead having a distal portion that is relatively flexible, a proximal portion that is relatively stiff, and a transition portion which has a variable transition stiffness. The transition stiffness varies over the length of the transition portion that generally decreases in a distal direction. The relatively stiff proximal portion of the lead gives the lead steerability while the gradual change in stiffness in the transition portion reduces the likelihood that the lead will prolapse when it is guided into a branch vein. The distal stiffness is less than the proximal stiffness giving the lead a safe end that is unlikely to puncture vascular walls and is able to maneuver around various tortuosities when the lead is implanted into a patient.
摘要翻译：根据一个实施例，本发明包括细长的可植入医疗引线，其具有相对柔性的远侧部分，相对刚性的近端部分和具有可变过渡刚度的过渡部分。过渡刚度在远端方向上通常减小的过渡部分的长度上变化。引线的相对刚性的近端部分具有引导操纵性，而过渡部分中刚度的逐渐变化降低了当引导到分支静脉时引线脱垂的可能性。远端刚度小于近端刚度，使得引线成为不可能穿透血管壁的安全端，并且当铅被植入患者时能够围绕各种曲折进行操纵。

摘要： A lead assembly for an implantable medical device includes a lead body having a proximal end, a distal end, and a longitudinal axis that extends between the proximal end and distal end. The lead assembly also includes a strain relief tube that surrounds a portion of the lead body. The strain relief tube includes a flexible material configured to include contours such that the portion of the lead body surrounded by the strain relief tube maintains a formed shape that varies from the longitudinal axis of the lead body. The contours vary in response to forces on the lead body to prevent strain at the distal end of the lead body.
