Patent number: 10632281Abstract: A system and method for delivering a drug to a target site within a patient's body. The system and method include a steerable guide catheter and a drug delivery catheter. The steerable guide catheter has a first extension tube and a second extension tube that are joined together and form a shoulder. The delivery catheter has a distal docking segment and a proximal docking segment. The guide catheter is inserted into the patient's body, then the delivery catheter is inserted into the guide catheter. The distal docking segment engages the first extension tube, the proximal docking segment engages the second extension tube, and the shoulder limits the distance the delivery catheter can be inserted into the guide catheter. Also, once the delivery catheter is inserted it can be rotated to attach the helical tip to the target site. The guide catheter also includes a steering mechanism as well as a friction mechanism which controls the tension on the steering mechanism.Type: GrantFiled: April 21, 2014Date of Patent: April 28, 2020Assignee: BioCardia, Inc.Inventors: Daniel C. Rosenman, Peter A. Altman, Brian K. Hakim, Daniel J. Kayser, Robert E. Maston, Douglas McEtchin

Patent number: 5144946Abstract: A pacemaker having a single integrated interconnect structure is disclosed which combines the functions of a flexible interconnect cable and a protective lid for a hybrid substrate. The integrated interconnect structure is a molded three-dimensional part having a lid portion and a feedthrough portion. An electronic substrate can be mounted onto the integrated interconnect structure wherein electrical conductors formed within the integrated interconnect structure connect the electronic substrate to the battery terminals and to the pacemaker feedthroughs. In one embodiment, the integrated interconnect structure may be adapted to have additional electronic circuitry mounted directly onto a flat inner cavity within the lid portion, thereby enabling electronic components to be easily added or modified without complicating the assembly operations of the pacemaker.Type: GrantFiled: August 5, 1991Date of Patent: September 8, 1992Assignee: Siemens Pacesetter, Inc.Inventors: Alvin H. Weinberg, Robert E. Maston

Patent number: 5103818Abstract: An arrangement is provided which enables the rapid and effective termination of electrical junctions for an implantable medical device such as a heart pacemaker, a defibrillator, or a cardioverter. A circuit board supporting electronic circuitry is receivable in a housing for the medical device and is provided with a plurality of female connectors on its outer surface. The female connectors are positioned and shaped to receive and guide mating male components into abutting engagement therewith. The mating male components include feedthrough wires which extend between the interior and the exterior of the housing and conductive pins from a battery used to power the medical device. When the male components and female connectors are in abutting engagement, they are fusion welded as by a laser or electron beam.Type: GrantFiled: November 13, 1990Date of Patent: April 14, 1992Assignee: Siemens-Pacesetter, Inc.Inventors: Robert E. Maston, Donald W. Karl, Alvin H. Weinberg
