Electrical leads are also provided with retention features to secure the implantation tool to the lead during use.

Abstract: An electrical lead including a coupling feature thereon to secure an implantation tool thereto is disclosed.

Abstract: The present invention provides systems, devices and methods for positioning a lead at a target site in a patient's body. Electrical lead positioning systems include positioning devices that aid in positioning electrodes of an electrical lead closer to the therapy site.

Abstract: The existing bat cap is removed and the bat is threaded to match the threads on the “Adjustable Sports Bat Plug Weight” and the “Adjustable Sports Bat Plug Weight” is screwed in until tight. The “Adjustable Sports Bat Plug Weight” comes in varying weights measured in half ounce increments to provide a full range of available options.

Abstract: A connector assembly for interconnecting separate sections of tubing, e.g., medical tubing. Connector assemblies are, in one embodiment, a two-piece construction having a connector pin and a connector sleeve. An exemplary connector sleeve includes a first end, a second end, and a passageway extending between the first and second ends. The passageway, in one embodiment, is stepped, e.g., defined by both a bore of a first diameter and a bore of a second diameter.

Abstract: A connector assembly for interconnecting separate sections of tubing, e.g., medical tubing, and a method for using the same. Connector assemblies in accordance with embodiments of the present invention may be a two-piece construction having a connector pin and a connector sleeve. In addition to providing secure, substantially leak-free coupling of the tubing sections, connector assemblies as shown and described herein may also provide strain relief to the tubing interconnection.

Abstract: Apparatus and methods for securing a therapy delivery device relative to a burr hole. In one embodiment, the apparatus includes a base that is securable to bone, without the use of fasteners, either before or after insertion of the therapy delivery device through the burr hole. The apparatus may further include a stabilizer that may be engaged with both the base and the therapy delivery device while the delivery device is held with positioning apparatus. The base and/or stabilizer may frictionally engage the delivery device, e.g., receive it with interference, to secure the device in two or more non-parallel directions. In some embodiments, at least the stabilizer may include a surface coating or treatment operable to enhance frictional engagement with the therapy delivery device.

The base may frictionally engage the delivery device, e.g., receive it with interference, to secure the device relative to the burr hole. The base may have a relatively low profile such that a flange portion of the base extends only minimally above a cranial surface, e.g., about 4 millimeters or less.

Abstract: Apparatus for securing a therapy delivery device relative to a burr hole and method for making same. In one embodiment, the apparatus includes a base for seating in or near the burr hole. The apparatus may further include a stabilizer that may be engaged with the therapy delivery device. The stabilizer may include a surface coating or treatment operable to enhance frictional engagement with the therapy delivery device.

Abstract: A repository, a loader, a model generator, a constraint generator, and a number of timing analysis tools, are provided for managing timing requirement specifications and measurements, and generating timing models and constraints of a VLSI circuit. The repository stores the timing specifications and measurements for each pin instances and each flow through arc instances. Timing specifications and measurements are identified by their classes including at least one current specification class and at least one measurement class for one timing analysis tool. Additionally, the repository stores a number of characteristics for each pin instance, the pin compositions of each net, and the hierarchical relationship of the functional block instances. The loader loads the various information into the repository. The timing model generator generates the timing models for the various functional blocks, using the stored information in the repository.
