Patent number: 7351247Abstract: The present invention provides devices and associated methods for delivering side-to-side and end-to-side anastomotic connectors to join any two (or more) vessels together such that fluid communication is established between the lumens of the two or more joined vessels. The systems of the present invention employ one or more deployment mechanisms over which the anastomotic connector is positioned for delivery and subsequently deployment within a vessel. The deployment mechanisms may be inflatable balloons or expandable baskets or a combination thereof or the like, which, when inflated and/or expanded, cause one or more portions of the anastomotic connector to deploy.Type: GrantFiled: September 4, 2002Date of Patent: April 1, 2008Assignee: Bioconnect Systems, Inc.Inventors: David Kupiecki, Stanley R. Conston, Candice Danielle Pinson, Ron K. Yamamoto, Meir Moshe, Aaron Miller

Publication number: 20080058704Abstract: The invention provides tools, materials and related methods to surgically access the suprachoroidal space of an eye for the purpose of performing minimally invasive surgery or to deliver drugs to the eye. The invention provides a flexible microcannula device (11, 13) that may be placed into the suprachoroidal space (12, 14) through a small incision (12A) of the overlying tissues, maneuvered into the appropriate region of the space, and then activated to treat tissues adjacent to the distal tip of the device.Type: ApplicationFiled: April 29, 2005Publication date: March 6, 2008Inventors: Michael Hee, Stanley Conston, David Kupiecki, John McKenzie, Ronald Yamamoto, Michael Nash

Publication number: 20070179471Abstract: Microcannulae are constructed with multiple components in a composite design, allowing the microcannulae to have varying mechanical and delivery properties that will enable ophthalmic treatments by minimally invasive means. The microcannula includes at least one flexible, tubular communicating element with an outer diameter of 350 microns or less, a proximal connector for introduction of materials, energy or tools. It may also include a reinforcing member attached to the communicating element, which may be designed to create variable stiffness along the length of the microcannula. The microcannula may also include other features such as a signal beacon near the distal tip.Type: ApplicationFiled: March 28, 2007Publication date: August 2, 2007Inventors: Jeffrey Christian, Stanley Conston, David Kupiecki, John McKenzie

Publication number: 20070073275Abstract: Ophthalmic microsurgical instruments may be directly inserted into Schlemm's Canal to allow controlled treatment or removal of adjacent tissues such as the trabecular meshwork or the juxtacanalicular tissues to affect an increase in aqueous outflow and the reduction of intra-ocular pressure. The instrument allows the directed access to Schlemm's Canal by a flexible microcannula (1). The instrument is useful in allowing controlled guidance by the surgeon while viewing through a surgical microscope or by non-invasive medical imaging.Type: ApplicationFiled: April 16, 2004Publication date: March 29, 2007Inventors: Stanley Conston, David Kupiecki

Publication number: 20060195187Abstract: An implant is placed within Schlemm's canal of the eye and provides tension to the trabecular meshwork. The tension is continuous and increases the aqueous outflow without the necessity of administering cholinergic drugs to treat glaucoma.Type: ApplicationFiled: December 16, 2005Publication date: August 31, 2006Applicant: iScience Surgical CorporationInventors: Robert Stegmann, Stanley Conston, David Kupiecki, John McKenzie, Candice Pinson, Ronald Yamamoto

Publication number: 20060094930Abstract: A catheter system and corresponding methods are provided for accessing a blood vessel true lumen from a sub-intimal plane of the vessel. The catheter system includes visualization elements for determining the orientation of the true lumen with respect to the sub-intimal plane at an identified entry site from a position in the sub-intimal plane. The entry site is distal to a chronic total occlusion (CTO). The catheter system also includes a system for physically securing tissue of the sub-intimal plane at the entry site to the catheter system. The attaching system reduces or eliminates catheter float within the sub-intimal space. The catheter system further includes re-entry devices to establish and maintain a path from the sub-intimal plane back into the vessel true lumen.Type: ApplicationFiled: December 13, 2005Publication date: May 4, 2006Inventors: Kurt Sparks, Jeffrey Emery, Brent Seybold, David Kupiecki, C. Pinson, Allen Madsen, Michael Keleher, Sergio Salinas, Benjamin Clark, Matthew Selmon

Patent number: 6638243Abstract: This is a medical catheter made up of a body having on its distal end portion an expandable balloon and, proximal of the balloon, a delivery lumen ending in a port through which therapeutic or diagnostic agents may be delivered. In one variation, a single inflation/wire lumen extends from the catheter proximal end to the catheter distal end, through which the balloon is inflated with pressurized fluid and through which a guide wire extends. The guide wire may have a valve plug for selectively seating against a valve seat of the catheter distal end to seal the inflation/wire lumen for balloon inflations. In another variation, a vaso-occlusive agent is disposable within a delivery lumen in a catheter coupled with a steerable guidewire. The delivery lumen ends in a delivery port near to and proximal of an expandable balloon located at the catheter's end. A single inflation/wire lumen may also be provided for facilitating both balloon inflation and guide wire tracking.Type: GrantFiled: August 2, 2002Date of Patent: October 28, 2003Assignee: Target Therapeutics, Inc.Inventor: David Kupiecki

Patent number: 6344041Abstract: This is an artificial occlusion kit for implanting and retaining an artificial occlusion device in a body space adjacent to and extending from a body lumen in a mammal. The includes at least one occlusion device and a retaining device for blocking the migration of the occlusion device out of the occlusion site. The retaining device is radially expandable at a retaining site adjacent the body space to be occluded to a diameter that is sufficient to engage the body lumen wall at the retaining site and form a barrier across the entrance zone of the body space to be occluded. The expanded retaining device also forms a lumen for flow through body lumen at the retaining site. At least one semi-penetrable space may also be provided in the retaining device, allowing introduction of occlusion devices into the body space to be occluded, but preventing subsequent migration of the occlusion devices out of the body space.Type: GrantFiled: October 26, 2001Date of Patent: February 5, 2002Inventors: David Kupiecki, Clifford Teoh, Hong Doan, Son M.
