| 20120016383 | METHOD AND APPARATUS FOR CLOSING AN OPENING IN THICK, MOVING TISSUE - A device for placing one or more sutures through a section of tissue, especially a section of thick and/or moving tissue such as the wall of a beating heart. The device includes a tissue welting tip having a trough for forming a welt in a tissue section, an alignment guide pivotally mounted in the distal end adjacent to the trough, and having an opening receiving a guide wire and an elongated sleeve slidably engagable with the guide wire there through. The device also includes one or more expandable tissue engaging member(s) on the sleeve selectively expandable from a collapsed configuration having a diameter small enough to pass through the opening in the tip to an expanded configuration having a diameter large enough to engage a tissue section and urge it into the trough to form a welt in the tissue section and a retractable needle extendable through at least two portions of a tissue section while the tissue section is engaged with the trough. | 01-19-2012 |
| 20110251641 | BIOABSORBABLE MAGNESIUM KNOTS FOR SECURING SURGICAL SUTURE - A crimpable magnesium sleeve for securing a suture within the body and for dissolving over time while introducing only compatible amounts of magnesium into the body. An instrument for placing such a sleeve on a suture crimping the sleeve and cutting the suture after placement. An alloy of magnesium, zinc, and aluminum may be used to form the sleeve. | 10-13-2011 |
| 20110118758 | MULTI-FIRE SUTURING INSTRUMENT WITH PROXIMAL FERRULE RELEASE FEATURE - A surgical suturing instrument has a needle which traverses at tissue receiving gap and picks up suture distal to the gap. This invention provides an automated mechanism enabling the suture to be removed from the needle after the needle is retracted proximal to the tissue gap. This mechanism provides enhanced device reloading and other potential uses. | 05-19-2011 |
| 20100211083 | MEDICAL INSTRUMENT TO PLACE A PURSESTRING SUTURE, OPEN A HOLE AND PASS A GUIDEWIRE - A therapeutic instrument for the ergonomic, effective and safe opening and closing of targeted remote tissue sites; includes a pistol grip style handle with a hand activated lever for needle deployment and, optionally, with features to control tissue cutting and guide wire installation; also incorporates a specialized elongated rigid or flexible instrument shaft, which enables vacuum assisted holding of tissue at a uniquely contoured distal tip, where placement of a suture in a purse string configures occurs along with, if desired, tissue cutting and guide wire passage. | 08-19-2010 |
| 20100211082 | MEDICAL INSTRUMENT TO PLACE A PURSESTRING SUTURE, OPEN A HOLE AND PASS A GUIDEWIRE - A therapeutic instrument for the ergonomic, effective and safe opening and closing of targeted remote tissue sites; includes a pistol grip style handle with a hand activated lever for needle deployment and, optionally, with features to control tissue cutting and guide wire installation; also incorporates a specialized elongated rigid or flexible instrument shaft, which enables vacuum assisted holding of tissue at a uniquely contoured distal tip, where placement of a suture in a purse string configures occurs along with, if desired, tissue cutting and guide wire passage. | 08-19-2010 |
| 20090222027 | FERRULE HOLDER WITH SUTURE RELIEF LOBES - A surgical suturing instrument has a chamber for receiving and aligning a ferrule with a reciprocating needle. The chamber includes a plurality of protuberant concave and convex surfaces for positioning and aligning the ferrule within the chamber and the plurality of suture receiving chambers disposed between the aligning ridges for receiving a suture and preventing the suture from jamming the ferrule in the chamber. | 09-03-2009 |
