The invention relates to a nozzle having a piercing projection for safe and efficient release of viscous material from a collapsible tube sealed at a front end and a rear end by tie clips when housed within a dispensing tool. The piercing projection extends from the nozzle interior surface. The piercing projection is arranged to pierce the front end of the collapsible tube along a tear line to form a flap of the collapsible tube to which the front end tie clip remains attached. An upstanding wall extends from the nozzle interior surface to define a retention shelf between the upstanding wall and the nozzle interior surface. The retention shelf is configured to receive and retain therein the flap and the front end tie clip during dispensing to enable unobstructed flow of the viscous material through the dispensing end opening.

This invention belongs to the field of vehicle safety technology and discloses a constant-resistance buffer vehicle energy-absorbing box, including a support tube, a collapsible tube, a pressure-reinforcing spherical crown, and a radial constriction tube. The support tube is slidably connected inside the collapsible tube, and the end of the support tube near the collapsible tube receives the pressure-reinforcing spherical crown, with the support tube and the pressure-reinforcing spherical crown in spherical contact. The inner diameter of the pressure-reinforcing spherical crown is a variable-diameter through hole. The end of the collapsible tube away from the support tube is connected to the radial constriction tube. The other end of the radial constriction tube is interference-fitted to the variable-diameter through hole. The inner collapsible tube structure of this invention can withstand a certain amount of off-center impact. After exceeding the bearing capacity of the inner collapsible tube structure, the radial constriction tube and the pressure-reinforcing spherical crown can bend and deflect with the collapsible tube, and the radial constriction tube and the pressure-reinforcing spherical crown can also remain coaxially aligned, ensuring that the radial constriction tube undergoes constant-resistance deformation after passing through the pressure-reinforcing spherical crown and does not get stuck. The constant-resistance deformation buffer of the vehicle energy-absorbing box generates minimal support reaction force, minimizing damage to people and vehicles, and greatly improving the passive safety of the vehicle.

An apparatus for facilitating control of fluid or slurry movement in a collapsible tube is provided. The apparatus includes the tube. The tube includes first and second opposing wall portions having circumferentially varying thickness including first and second maximum thicknesses respectively, the first and second maximum 5 thicknesses disposed on opposite sides of the tube, and third and fourth opposing wall portions between the first and second opposing wall portions, the third and fourth opposing wall portions having third and fourth circumferentially minimum thicknesses respectively, the third and fourth minimum thicknesses disposed on opposite sides of the tube about halfway between the first and second maximum thicknesses. 10 wherein the first and second opposing wall portions are configured to be engaged by a tube engager to cause the tube to fold at the third and fourth minimum thicknesses to seal the tube. Other apparatuses, systems, and methods are disclosed.

A method and apparatus for surgically repairing a tear in soft tissue is disclosed. A plurality of collapsible tubes are positioned about the suture. The collapsible tubes are pushed through soft tissue and orthopedic mesh on opposite sides of a tear in soft tissue. When tension is applied to the suture, the tubes are compressed to fix the suture to the soft tissue and draw the soft tissue portions together.

A guide extension catheter is provided that can provide a low-friction, large-diameter (for a given compatible guide catheter size) passageway proximal to and optionally through a target lesion within the vasculature, thereby reducing micro- and macro-vasculature damage due to the delivery of an interventional device. A guide extension catheter is disclosed that is positionable within a guide catheter and configured to receive an interventional device for insertion into the vascular system. The guide extension catheter includes a push member, a first reinforcing member in contact with the push member, and a radially collapsible tubular membrane in contact with the push member and the first reinforcing member. The tubular membrane is positioned distal to the first reinforcing member and is radially collapsed or wrapped around the push member prior to receiving the interventional device. The push member provides sufficient column strength to prevent longitudinal collapse of the tubular membrane during use.

An applicator for use with a hot melt adhesive dispensing system is provided. The applicator includes an applicator body configured to receive a collapsible tube of adhesive. The applicator body includes a housing wall defining a receiving cavity capable of housing the collapsible tube, a dispensing port defined within a distal portion of the housing wall, a cooling air inlet formed w ithin a first side portion of the housing wall, and a cooling air outlet formed through a second side portion of the housing wall. In one embodiment, the cooling air outlet is disposed at a location within the housing wall that is substantially opposite from the portion of the housing wall through which the cooling air inlet is formed. The applicator may also include an end cap comprising a collapsing air inlet; a piston configured to be disposed within the receiving cavity; an angled heat conductor disposed within the dispensing port of the applicator body; and athermal isolator disposed about the angled heat conductor.

An anchor assembly is provided. The anchor assembly includes a holder defining a passageway therethrough, and a collapsible tube positioned partially within the passageway, the collapsible tube slidable relative to the holder to transition the anchor assembly between i) an unlocked position in which a medical device lead extending through the anchor assembly is slidable relative to the anchor assembly and ii) a locked position in which the medical device lead is fixedly coupled to the anchor assembly.
