摘要： An occlusive implant delivery assembly includes a rapid response decoupling or detachment mechanism that does not effect significant migration of the implant during release. The assembly includes an occlusive implant device, such as an embolic coil, a pusher or device to carry the implant to the selected location, and an expandable coupling-decoupling mechanism for releasing the implant at the selected site. The mechanical construction provides rapid release times. In addition, the releasing mechanism generally operates without exerting any significant force on the implant, thereby avoiding any significant displacement of the implant during release.

摘要： An access platform having a first and a second blade interconnected to a spreader member that laterally drives the blades apart or together and support pads interconnected to a blade. A torsional member is operably interconnected to a blade and the spreader member and is used to vertically displace the interconnected blade and, thus, increase a surgeon's working space and visual access for the dissection of an internal mammary artery. A tissue retractor interconnected to the blades and is used to draw the soft tissue around an incision away from the surgeon's working area.

摘要： An access platform having a first and a second blade interconnected to a spreader member that laterally drives the blades apart or together and a sternal pad interconnected to a blade. The superior blade is preferably pivotally coupled to the spreader member such that it naturally rises as the blades are separated. Alternatively, a vertical displacement member is operably interconnected to a blade and the spreader member and is used to vertically displace the interconnected superior blade and, thus, increase a surgeon's working space and visual access for the dissection of an internal mammary artery. A tissue retractor is interconnected to the blades to draw the soft tissue around an incision away from the surgeon's working area.

摘要： A liner is advanced through a narrowed region in a vessel such as the internal carotid artery. The liner is advanced through the narrowed region in a collapsed position. A stent is then advanced through the liner and expanded to open the narrowed region. The liner may also have an anchor which expands an end of the liner before the stent is introduced.

摘要： A surgical instrument is configured to aid in performing a procedure of detaching an internal mammary artery (IMA) and the like, from the connecting tissues and side branch vessels which surround the artery in its native location, wherein the detaching procedure is preliminary to the performing of a coronary artery bypass grafting procedure and wherein the IMA is detached via a minimally invasive thoracotomy. To this end, an elongated slender rod includes a handle at its proximal end and an artery engaging loop, arc, fork configuration, or hook at its distal working end. Embodiments may incorporate electrosurgical capability or electrical insulation. A surgeon thus has means for harvesting an intact and undamaged graft vessel from its native location through a minimally invasive incision with enhanced speed, visibility, and freedom of motion.

摘要： An artery, vein, aneurysm, vascular malformation or arterial fistula is occluded through endovascular occlusion by the endovascular insertion of a platinum wire and/or tip into the vascular cavity. The vascular cavity is packed with the tip to obstruct blood flow or access of blood in the cavity such that the blood clots in the cavity and an occlusion if formed. The tip may be elongate and flexible so that it packs the cavity by being folded upon itself a multiple number of times, or may pack the cavity by virtue of a filamentary or fuzzy structure of the tip. The tip is then separated from the wire mechanically or by electrolytic separation of the tip from the wire. The wire and the microcatheter are thereafter removed leaving the tip embedded in the thrombus formed within the vascular cavity. Movement of wire in the microcatheter is more easily tracked by providing a radioopaque proximal marker on the microcatheter and a corresponding indicator marker on the wire. Electrothrombosis is facilitate by placing the ground electrode on the distal end of the microcatheter and flowing current between the microcatheter electrode and the tip.

摘要： Several embodiments of a clamping device are disclosed, for tightening and securing a purse string suture used to seal the tissue around a cannula or a catheter or the like placed in a heart, major vessel or other tissue structure. The clamping device includes a compressible sleeve means solidly secured at a proximal end to a compression-applying means such as a clamp mechanism. A suture-pulling needle is inserted through a common lumen, whereby the trailing ends of the suture thread which forms the purse string suture may be pulled through the compressible sleeve means and clamp mechanism. Application of a force to the clamp mechanism while it is not locked to the trailing ends compresses the compressible sleeve means. Release of the clamp mechanism locks the enclosed trailing ends of the suture thread. The compressed sleeve means applies constant and precalibrated tension on the purse string suture to continuously maintain the seal about the cannula. The clamping device is removed by unlocking the clamp mechanism and withdrawing the device from the suture thread.

摘要： An automatic purse string suture device is disclosed that enables a surgeon to install a purse string suture in tissue structures, particularly for sealing the tissue about a cannula. The device is particularly suited for minimally invasive cardiothoracic procedures and is comprised of an applicator having an elongated structure with protrusions extending from the distal edge thereof. Also provided are means for advancing a needle through a passage to pass a suture through tissue that has been conformed to the distal edge of the device. Various means for conforming the tissue to the distal edge are disclosed as are methods for using the device to facilitate cardiothoracic surgery.
