摘要： Sutureless pump connectors are discussed. The sutureless pump connectors include a restraint (20) and a lock (10). The restraint has a proximal portion capable of engaging a portion of an implantable pump, such as a port. The restraint also has a distal portion capable of engaging a catheter. The lock is configured to secure the restraint to secured position relative to the pump and the catheter. The restraint may have a tab configured to secure the lock on the restraint. The tabs may be configured to releasably secure the lock.

The first end (24) of the connector (20) is inserted into a proximal connector-receiving portion to form a first interlock fit, and the second end (32) of the connector (20) is inserted into the distal connector-receiving portion to form a second interlock fit, resulting in a fluid tight connection between the proximal connector-receiving portion and the distal connector-receiving portion, with at least a middle portion (28) of the connector (20) exposed. The middle portion (28) of the connector (20) can include a suture receiving section that can be sutured to tissue of patient.

摘要： Shields within implantable leads increase the torsional stiffness of the leads. The torsional stiffness may be reduced by cutting the shield axially to break the circumferential mechanical continuity of the shield. The circumferential shielding continuity of the shield may be re-established to preserve the shielding effect in various manners. The shield may overlap onto itself to close the slot created by the cut. A shield patch may be placed across the slot created by the cut. The shield may be located between two insulation layers of the lead. The shield may be cut and then the slot closed prior to application of the outer insulation layer. The outer insulation layer may then be added over the shield. The outer insulation layer may be compliant so that once covered, the circumferential mechanical continuity of the shield remains broken.
摘要翻译：可植入引线内的护盾增加引线的扭转刚度。可以通过轴向切割屏蔽来破坏屏蔽件的周向机械连续性来减小扭转刚度。可以重新建立屏蔽件的圆周屏蔽连续性，以各种方式保持屏蔽效果。屏蔽可能会重叠在自身上，以关闭由切割创建的槽。屏蔽贴片可以放置在由切口产生的狭槽上。屏蔽可以位于引线的两个绝缘层之间。屏蔽可以被切割，然后在施加外绝缘层之前关闭槽。然后可以将外部绝缘层添加到屏蔽上。外绝缘层可以是柔性的，使得一旦被覆盖，屏蔽层的周向机械连续性保持断裂。

摘要： An in-vitro model apparatus of a human spine and methods for detecting and analyzing substance distribution patterns therein. In one embodiment, the model apparatus includes a column body defining a passageway that substantially mimics the size, shape, and structure of an adult human spinal canal. Also included is a cord structure that may be located and anchored within the passageway. The cord structure substantially mimics the size, shape, and structure of an adult human spinal cord. For example, the cord structure may include connecting elements that resemble nerve roots, dentate ligaments, and the septum posticurn of a human spine. The passageway of the model apparatus may be filled with a first fluid that simulates cerebro-spinal fluid (CSF), and a second fluid containing a drug (or simulated drug) may be introduced into the passageway, after which the drug's distribution within the passageway may be analyzed.
