摘要： Disclosed is an expandable percutaneous sheath, for introduction into the body while in a first, low cross-sectional area configuration, and subsequent expansion to a second, enlarged cross-sectional configuration. The sheath is maintained in the first, low cross-sectional configuration by a removable tubular restraint or by structural elements built into the wall of the expandable portion of the sheath. In one application, the sheath is utilized to introduce a formed in place orthopedic fixation rod such as for use in spinal fixation procedures, preparation of a spinal segment, or placement of a vertebral body spacer. The sheath can further comprise structural elements to permit re-collapse of the sheath under fluid pressure following completion of the procedure and prior to removal from the patient.

摘要： An access device comprises a thin-walled sheath that is insertable into a patient through a small surgically created incision. The incision may be created using a cutdown or a percutaneous method such as that known as the Seldinger technique. Once inserted and advanced to the target surgical site, the sheath is selectively, and controllably, expanded to a desired diameter. The thin wall of the sheath is fabricated from a rectangular piece of material such as metal or plastic with two cut edges. The rectangular piece of metal or plastic is rolled tightly to create the small diameter configuration that is inserted into the patient. A cam or control member is affixed to the innermost edge of the rectangular piece of metal or plastic. The control member extends to the proximal most portion of the sheath. By rotating the control member, the operator causes the thin wall piece of rolled material to unfurl into a larger or smaller diameter, depending on the direction of rotation. A mechanical lock at the distal end of the sheath permits the control member to be selectively constrained from rotation and thus lock the sheath diameter in place.

摘要： A stent and stent catheter for intra-cranial use. The stent is a rolled sheet stent and is releasably mounted on the distal tip of the catheter by means of a non-sliding retention and release mechanism. The non-sliding release mechanism is operated remotely at the proximal end of the catheter by means of a linear translator. The stent is rolled tightly on the distal tip of the catheter and flexibility of the tightly rolled stent is promoted by ribbed or slatted construction (or, alternatively, slotted construction) in which the various layers of the stent are provided with numerous slats which counter align when the stent is expanded to form an imperforate wall from a plurality of perforate layers.

摘要： Devices and methods are disclosed for achieving hemostasis at a wound site following an endovascular procedure. Such wound sealing is necessary generally following a percutaneous procedure where a percutaneous cannula is withdrawn from the vasculature leaving an entry site to the vessel that could bleed if steps are not taken to stop said bleeding. The devices and methods disclosed herein are especially useful in the catheterization laboratory following interventional cardiology or interventional neuroradiology procedures. The devices utilize the introduction sheath that was originally used for the procedure as a guide for the closure. The closure device is inserted through the introduction sheath once any therapeutic or diagnostic devices have been removed. The closure device comprises a two-part sealing material housed in a reservoir system, a mixing chamber, a delivery cannula, exit ports, and a vessel location device. The sealing material generally comprises materials such as albumin and polyethylene glycol, or the like. The sealing device works in conjunction with the already placed sheath to eliminate the step of replacing said sheath, an action that increases procedural time and may contribute to further wound damage and reduced sealing effectiveness.
摘要翻译：公开了用于在血管内手术后在伤口部位止血的装置和方法。这种伤口密封通常需要经皮操作，其中经皮插管从脉管系统中取出，留下进入血管的进入部位，如果不采取步骤来停止所述出血，则可能出血。本文公开的装置和方法在介入心脏病学或介入性神经放射学程序之后在导管实验室中特别有用。这些装置使用最初用于该过程的引入护套作为关闭的指导。一旦任何治疗或诊断装置被去除，封闭装置就插入导入鞘中。闭合装置包括容纳在储存器系统中的两部分密封材料，混合室，输送套管，出口和容器定位装置。密封材料通常包括诸如白蛋白和聚乙二醇的材料等。密封装置与已经放置的护套一起工作以消除更换所述护套的步骤，增加程序时间的作用并且可能有助于进一步的伤口损伤和降低的密封效果。

摘要： Devices and methods are disclosed for achieving hemostasis in solid visceral wounds. Such devices and methods are especially useful in the emergency, trauma surgery or military setting. In such cases, the patient may have received trauma to the abdominal viscera. The devices utilize flexible, variable depth transfixing bolts that penetrate the viscera. These bolts are pulled tight to bring the tissue into apposition and hold said tissue in apposition while the wound heals. These bolts, or soft tissue rivets, overcome the limitations of sutures that are currently used for the same purposes. The bolts come in a variety of lengths and diameters. Since the bolts are flexible, the curvature can be adjusted by the surgeon. The devices are flexible, bendable, and conformable in their wet or dry state. They can be used either straight or configured in a broad range of curvatures to suit the needs of various pathologies. The bolts include pressure plates that are capable of exerting compressive pressure over broad areas of visceral wounds without causing tearing of the friable parenchyma. The bolts may be placed and removed by open surgery or laparoscopic access. The bolts can be placed into tissue where both sides of the bolt are exposed, or the bolts can be placed blindly into tissue where the bolt does not protrude out of the tissue at its distal end.
摘要翻译：公开了用于实现固体内脏伤口止血的装置和方法。这种装置和方法在紧急，创伤手术或军事设置中特别有用。在这种情况下，患者可能已经接受了腹部内脏的创伤。这些装置使用穿透内脏的灵活，可变深度的穿透螺栓。这些螺栓被拉紧以使组织并入并且在伤口愈合时保持所述组织。这些螺栓或软组织铆钉克服了当前用于相同目的的缝合线的限制。螺栓具有各种长度和直径。由于螺栓是柔性的，因此外科医生可以调整曲率。这些装置在湿或干态下是柔性的，可弯曲的和适应的。它们可以直接使用或配置在广泛的曲率范围内，以适应各种病态的需要。这些螺栓包括能够在宽范围的内脏伤口施加压力而不会导致脆性薄壁撕裂的压力板。螺栓可以通过开放手术或腹腔镜进入来放置和移除。螺栓可以放置在组织中，螺栓的两侧被暴露，或者螺栓可以盲目地放置在组织中，其中螺栓不在其远端处从组织突出。

摘要： Devices and methods for achieving hemostasis and leakage control in hollow body vessels such as the small and large intestines, arteries and veins as well as ducts leading to the gall bladder and other organs. The devices and methods disclosed herein are especially useful in the emergency, trauma surgery or military setting, and most especially during damage control procedures. In such cases, the patient may have received trauma to the abdomen, extremities, neck or thoracic region. The devices utilize removable or permanently implanted, broad, soft, parallel jaw clips with minimal projections to maintain vessel contents without damage to the tissue comprising the vessel. These clips are applied using either standard instruments or custom devices that are subsequently removed leaving the clips implanted, on a temporary or permanent basis, to provide for hemostasis or leakage prevention, or both. These clips overcome the limitations of clips and sutures that are currently used for the same purposes. The clips come in a variety of shapes and sizes. The clips may be placed and removed by open surgery or laparoscopic access.

摘要： In one embodiment, an access sheath includes a movable coil sheath that is insertable into a patient through an endoluminal or surgical approach. The sheath is inserted into a patient in a flattened configuration. A plurality of separate coils, elements, or hoops are connected by a fixed member and a control member, which are moved relative to each other to flatten the coils or hoops. Once inserted and advanced to the target surgical site, the sheath is selectively, and controllably, unflattened or expanded to a desired diameter or cross-section. A control member is affixed to one edge of the sheath and runs in the axial direction. By translating the control member in a direction parallel to the axis of the sheath, the operator causes the hoops or coils to rotate into a plane perpendicular or lateral to the axis of the sheath. A mechanical lock at the proximal end of the sheath permits the control member to be selectively constrained from translation and thus lock the sheath diameter in place.
