US Patent:

55429254, Aug 6, 1996

Filed:

Feb 13, 1995

Appl. No.:

8/387977

Inventors:

Jean C. Orth - San Jose CA

Assignee:

Advanced Cardiovascular Systems, Inc. - Santa Clara CA

International Classification:

A61M 2900

US Classification:

604102

Abstract:

A dilatation catheter is described wherein a plurality of oblong perfusion ports are provided in the catheter shaft to provide perfusion flow of blood through the distal section of the catheter. Oblong perfusion ports are preferably provided both proximal and distal to the inflatable dilatation balloon. Orienting the long dimensions of the oblong perfusion ports at an angle from the longitudinal axis of the catheter shaft minimizes kinking of the catheter shaft when passing through tortuous passageways.

International Classification:

A61M 2902

US Classification:

606 27

Abstract:

A balloon dilatation catheter having means to raise the temperature of the working surface of the balloon while the balloon is being inflated during an angioplasty procedure. In one embodiment, the balloon is provided with a thin electrically conductive layer in heat transfer relationship therewith preferably on the interior surface of the balloon. Electrical power at radio frequencies is preferred and a coaxial cable is employed to deliver such power to a conductive layer for heating the balloon. In another embodiment, the balloon itself is formed of electrically conductive material. A perfusion lumen may be provided through the balloon with one or more proximal inlet ports and one or more distal discharge ports in fluid communication with the lumen to allow blood to pass through the balloon when it is inflated during angioplasty procedures. This facilitates the flow of oxygenated blood distally of the catheter when the balloon is inflated thus allowing for extended balloon inflations, e. g. , up to 30 minutes or more.

International Classification:

A61F 9/007
A61M 27/00

Abstract:

The present technology is directed to adjustable flow glaucoma shunts, systems, and methods for making and using such devices. In many of the embodiments described herein, the shunts include a drainage element configured to fluidly couple an anterior chamber of an eye and a target outflow location, such as a subconjunctival bleb space. The shunts can further include a flow control assembly coupled to the drainage element and configured to control the flow of fluid (e.g., aqueous) therethrough. The shunts can further include an outer membrane or bladder that encases the flow control assembly. The outer membrane can include a plurality of apertures that fluidly couple an interior of the outer membrane with an environment exterior to the outer membrane.

International Classification:

A61F 9/007

Abstract:

The present technology is directed to adjustable flow glaucoma shunts and methods for making and using such devices. In many of the embodiments described herein, the shunts include a generally flat frame. The frame can include an elongated portion having a lumen extending therethrough and a bladder portion defining an interior chamber that is in fluid communication with the lumen. When implanted in a patient's eye, aqueous can drain from the anterior chamber to a target outflow location via the lumen and interior chamber. In some embodiments, the shunts include a flow control assembly positioned within the interior chamber of the bladder portion to control the flow of aqueous through the lumen.

Inventors:

- San Jose CA, US
Jean C. ORTH - Morgan Hill CA, US

International Classification:

A61M 25/10

Abstract:

Medical devices and methods for delivering fluid. The medical devices include one or more needles for delivering fluid. The methods may optionally include expanding an expandable member such as an inflatable member to expand an expandable scaffold outward toward a lumen wall. The methods may include delivering a first fluid out of one or more needles, and delivering a secondary fluid (which may be the same type of fluid as the first fluid, or a different type of fluid) from the device without delivering the secondary fluid through a needle.
