Patent number: 8540694Abstract: Systems and methods for delivering drugs or other substances to target locations outside of blood vessel lumens or other body lumens. In some embodiments, a catheter having a penetrator is advanced into the body lumen and the penetrator is then advanced from the catheter toward a target location outside of that body lumen. The substance is then delivered through a the penetrator itself or through a delivery catheter that has been advanced through the penetrator to the target location. In other embodiments, the blood vessel or other body lumen is blocked at spaced-apart first and second locations and a quantity of the substance is introduced into the closed-off body lumen between the blocked first and second locations. The substance then diffuses into or through the wall of the vessel or body conduit to reach the target location.Type: GrantFiled: December 27, 2011Date of Patent: September 24, 2013Assignee: Medtronic Vascular, Inc.Inventors: J. Christopher Flaherty, Joshua Makower, Philip C. Evard, Patrick E. Macaulay, Jason B. Whitt, Robert C. Colloton, K. Angela Macfarlane

Patent number: 8459793Abstract: A conformable covering comprises an outer portion with rigidity to resist movement on the cornea and an inner portion to contact the cornea and provide an environment for epithelial regeneration. The inner portion of the covering can be configured in many ways so as to conform at least partially to an ablated stromal surface so as to correct vision. The conformable inner portion may have at least some rigidity so as to smooth the epithelium such that the epithelium regenerates rapidly and is guided with the covering so as to form a smooth layer for vision. The inner portion may comprise an amount of rigidity within a range from about 1×10-4 Pa*m3 to about 5×10-4 Pa*m3 so as to deflect and conform at least partially to the ablated cornea and smooth an inner portion of the ablation with an amount of pressure when deflected.Type: GrantFiled: September 13, 2012Date of Patent: June 11, 2013Assignee: NexisVision, Inc.Inventors: Eugene de Juan, Jr., Cary J.

Publication number: 20120136322Abstract: A therapeutic system comprises an ocular insert placed on a region outside an optical zone of an eye. The ocular insert comprises two structures: a first skeletal structure and a second cushioning structure. The first structure functions as a skeletal frame which maintains positioning of the implant along the anterior portion of the eye and provides support to the second, cushioning structure. This first structure maintains the attachment of the therapeutic system to the anterior portion of the eye for at least thirty days. In some embodiments the first structure remains a constant size and shape, e.g. a ring shape, a ring with haptics, or a curvilinear ring that is confined to and restrainingly engages the inferior and superior conjunctival fornices so as to retain the implant within the tear fluid and/or against the tissues of the eye.Type: ApplicationFiled: June 1, 2011Publication date: May 31, 2012Applicant: ForSight Labs, LLCInventors: Yair Alster, Eugene de Juan, JR., Cary J.

Patent number: 8083708Abstract: A transvascular system for delivering a drug to a tissue region from a blood vessel includes a catheter having a distal portion with puncturing, orientation, drug delivery, and imaging elements. The puncturing element is deployable for penetrating the vessel wall to access the tissue region. The orientation element has a predetermined relationship with the puncturing element, the imaging element detecting the location of the orientation element with respect to the tissue region to orient the puncturing element. The catheter is percutaneously introduced into the vessel, the puncturing element is oriented towards the tissue region, the puncturing element is deployed to access the tissue region, and the drug is delivered to the tissue region. An ablation device may also be deployed to create a cavity or fluid reservoir in the tissue region for receiving the drug therein, or an indwelling catheter may be advanced into and left in the tissue region.Type: GrantFiled: March 1, 2010Date of Patent: December 27, 2011Assignee: Medtronic Vascular, Inc.Inventors: Christopher Flaherty, Joshua Makower, Philip Evard, Patrick MacAulay, Jason Whitt, Robert Colloton, K.
