摘要： An aortic stent graft includes a stent with a framework attached to a fabric tube by a plurality of suture ties. The fabric tube includes a plurality of discrete attachment areas that are at least partially surrounded by at least one permeable graft area. The fabric tube is one of a weave and a knit of thermoplastic yarn. Each of the suture ties associated with the discrete attachment areas at least one of penetrates through and encircles a respective one of the discrete attachment areas. The weave or knit of the discrete attachment areas is identical to that of the permeable graft area with an exception that a wall thickness of each of the discrete attachment areas is flattened relative to, and thinner than, a wall thickness of the permeable graft area.

摘要： A line puller assembly for an endo-luminal delivery device is disclosed. The assembly comprises: a line puller body having a proximal end and a distal end; a line puller actuator assembly mounted to the line puller body for rotation about the line puller body, the actuator assembly including a line deflector ring, the ring including a first deflector line guide; a line anchor location on the line puller body; a first body line guide on the body, the line anchor location and the first body line guide positioned on opposite sides of the ring; and a line having an end portion anchored at the line anchor location on the line puller body, the line extending through the first line deflector ring, whereby a line path extends from the anchor location, through the first deflector line guide and past the first body line guide, the line path having a variable length.

摘要： The present embodiments provide systems and methods for deploying at least a portion of a stent. In one embodiment, the system comprises a cannula having an outer surface, and at least one coiled member having proximal and distal ends and a plurality of turns disposed therebetween. One of the proximal and distal ends of the coiled member is secured to the outer surface of the cannula, and the other of the proximal and distal ends of the coiled member is unsecured relative to the outer surface of the cannula. A portion of a stent is looped around the unsecured end of the coiled member and disposed within spacing between adjacent turns of the coiled member. Rotation of the cannula subsequently causes the portion of the stent to disengage from the coiled member.

摘要： There are disclosed implantable medical devices and apparatus for treating implantable medical devices during production, so as to cause the implantable medical devices to have abluminal surfaces and luminal surfaces with different functional characteristics and in particular surface energies. The luminal surfaces of the medical device are preferably coated with carbon, so as to have a low surface energy, which reduces the risk of thrombi forming when implanted into a patient's vessels. The abluminal surfaces are treated so as to have a high surface energy, such that a therapeutic, preferably bioactive, material, such as a drug, can adhere to the abluminal surfaces and preferably without any need for a containment layer such as polymer or other matrix material. Once the therapeutic material has been delivered into the tissue wall, the stent can remain within the patient's vessel without leaving any delivery artefacts, as occurs with some prior art drug eluting medical devices.

摘要： A conductive coating may be adhered to a structure comprising a hydrophobic and/or adhesion-resistant surface. The conductive coating may have a polymer backbone with conductive particles suspended in the backbone. In some embodiments, the conductive coating may be applied directly to the surface. In other embodiments, the conductive coating may be indirectly applied by first applying a primer adhesive to the outer surface, and then applying the conductive coating over the primer adhesive. An example structure may be a catheter of an endoscopic medical device, such as a bipolar sphincterotome, where the conductive coating functions as a return electrode.

摘要： A tissue-collection stylet is configured with inward-facing barbs, for use in a needle, and particularly configured to capture intact tissue cores suitable for histological analysis. The stylet may be provided together with a needle as part of a biopsy system in which the stylet remains at least partially or fully within a lumen of the needle during collection of tissue samples and/or other samples.

摘要： A gripper for gripping a tube for punching may include a first arm having a lower portion and an upper portion disposed outwardly from an upper surface of the lower portion. The upper portion extends to opposite first and second side surfaces and opposite third and fourth side surfaces, where opposite edges of the first and second side surfaces each meet an edge of one of the opposite third and fourth side surfaces. The second side surface includes a groove extending from the second side surface towards the first side surface and along a length of the second side surface. The groove is configured to receive at least a portion of a tube when a second arm like the first arm is disposed adjacent to and aligned with the first arm.

摘要： A device for use with a uterine tamponade balloon catheter apparatus, such as the Bakri postpartum hemorrhage balloon, is disclosed. The device comprises a stylet comprising a hub at its proximal end. The device is configured to be removably coupled to the tamponade balloon catheter apparatus to aid in the insertion and positioning of the tamponade balloon catheter within the uterine cavity, allowing the balloon to function as intended for the control and management of postpartum hemorrhage and uterine bleeding. Methods of use of the device are also disclosed.

摘要： The disclosure is directed to a system for maintaining hemostasis during introducing or withdrawing an interventional device. The system includes a housing. The housing includes a first end, a second end and a side wall defining a housing chamber. The system also includes a first funnel-shaped member disposed at least partially within the housing chamber. The first funnel-shaped member includes an inner portion, a middle portion and an outer portion. The inner portion of the first funnel-shaped member includes an elastic orifice, which is aligned with the through channel of the housing. The first funnel-shaped member includes an open configuration and a closed configuration. When the first funnel-shaped member is in the closed configuration, the elastic orifice is substantially closed, and when the first funnel-shaped member is in the open configuration, an interventional device is introduced through the system and the elastic orifice is open.
