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.

A dynamic spine stabilization element of a spine stabilization assembly includes first and second spinal rod segments that are coupled to one another via a connector. The connector allows movement of a spinal rod segment with respect to the coupling device and / or with respect to another spinal rod segment. This provides limited angulation (e.g. bending) between spinal rod segments allowing for limited movement of the vertebra connected by the present dynamic stabilization element. The connector may allow pivoting motion of the rod segments relative to the coupling device and relative to the other rod segment such as pivoting motion of one rod segment in a first plane and pivoting motion of the other rod segment in a second plane that is perpendicular to the first plane. The connector may also be bendable or flexible. In this form, the connector allows limited flexing, bending or angulation as between the associated spinal rod segments during use. Moreover, ends of the spinal rod segments may be configured to prevent or limit rotation of the spinal rod segments. The configured ends may cooperate with the coupling device to achieve the limitation on rotational movement.

An innovative bone anchor and methods for securing soft tissue, such as tendons, to bone, which permit a suture attachment that lies entirely beneath the cortical bone surface. Advantageously, the suturing material between the soft tissue and the bone anchor is secured without the need for tying a knot. The suture attachment to the bone anchor involves the looping of a length of suture around a pulley within the bone anchor, tightening the suture and attached soft tissue, and clamping the suture within the bone anchor. The bone anchor may be a tubular body having a lumen containing a plurality of suture-locking elements that clamp the suture therein. The locking elements may be thin and C-shaped. One or more locking plugs attached to separable actuation rods displace axially within the lumen and act on the locking elements to displace them radially. A generally uniform passage through the locking elements in their first positions converts to a smaller irregular passage after the locking plug displaces the elements to their second positions, thus effectively clamping the suture. The bone anchor further may include locking structure for securing itself within a bone cavity.

A coaxial cable connector includes a coupler, a post and a body member. One end of the body member includes a lip that is inserted through the opening in an annular collar of the coupler. In a cable-installed position, the shank of the post is received in the body member to form an annular chamber which is sufficiently narrow to compress the outer conductor and the jacket of a coaxial cable to establish a distal seal. Tightening of the coupler to the terminal compresses the lip between the flange of the post and the annular collar for establishing a proximal seal. Related methods also are provided.
