Filed:

May 8, 2002

Appl. No.:

10/142005

Michael A. Evans - Palo Alto CA, US

Assignee:

Bacchus Vascular inc. - Santa Clara CA

International Classification:

A61M 31/00

US Classification:

604508, 604509

Abstract:

Clot disruption and dissolution are achieved using a catheter having the ability to infuse a thrombolytic agent, aspirate clot and fluid, and allow passage of a guidewire. Optionally, the catheter may also include a mechanical agitator for further disrupt clot in the presence of the thrombolytic agent. A flow resistor in the catheter provides for infusion and/or aspiration to be concentrated primarily at a clot treatment area in a blood vessel while also providing optional infusion and/or aspiration distal to the treatment area. In some embodiments, infusion, aspiration and guidewire passage occur through a common lumen. The thrombolytic agent, such as tPA, streptokinase, or urokinase, is directly released into the clot at the point where the agitator is engaging the clot. In this way, the thrombolytic activity of the agent is enhanced and the dissolution of the clot is improved.

Abstract:

Clot disruption and dissolution are achieved using a catheter having the ability to infuse a thrombolytic agent, agitate the clot and agent, and aspirate broken-up clot from the blood vessel. A flow resistor in the catheter provides for infusion and/or aspiration to be concentrated primarily at a clot treatment area in a blood vessel while also providing optional infusion and/or aspiration distal to the treatment area. In some embodiments, infusion, aspiration and guidewire passage occur through a common lumen.

Abstract:

Disclosed herein is a magnetic navigation enabled tool configured for the delivery of an implantable medical lead. The tool includes a tubular body, a sensor and a conductor. The tubular body includes a distal end, a proximal end, an inner layer including an outer circumferential surface, a lumen inward of the inner layer, and an outer layer over the outer circumferential surface of the inner layer. The sensor is on the tubular body near the distal end. The conductor extends from the sensor coil towards the proximal end imbedded in the inner layer.

International Classification:

G01R 31/04
H01R 11/22

US Classification:

324538, 439266

Abstract:

Implementations of the present disclosure involve an internal pulse generator for administering electrotherapy via an implantable medical lead having a lead connector end on a proximal end of the lead. In addition, implementations involve testing of the medical lead at the proximal lead connector end to ensure proper placement of the lead, and an interface device for facilitating the connection of the proximal lead connector end to a testing device. The interface device may provide for one or more electrical connection points disposed on a connector sleeve. The connection points provide electrical communication between the lead connector end of the lead and one or more leads of a testing device in such a manner as to minimize potential damage to the lead connector end.

International Classification:

A61N 1/375

Abstract:

A biostimulator, such as a leadless cardiac pacemaker, including coaxial fixation elements to engage or electrically stimulate tissue, is described. The coaxial fixation elements include an outer fixation element extending along a longitudinal axis and an inner fixation element radially inward from the outer fixation element. One or more of the fixation elements are helical fixation elements that can be screwed into tissue. The outer fixation element has a distal tip that is distal to a distal tip of the inner fixation element, and an axial stiffness of the outer fixation element is lower than an axial stiffness of the inner fixation element. The relative stiffnesses are based on one or more of material or geometric characteristics of the respective fixation elements. Other embodiments are also described and claimed.
