An insertion apparatus and a method for use with a device for delivery of a therapeutic fluid into a body of a patient and/or for sensing of a bodily analyte are disclosed. The apparatus includes a housing adapted for loading therein at least one cannula cartridge unit having a protective member. The protective member accommodates at least one penetrating cartridge having a subcutaneously insertable element and a penetrating member. The apparatus includes a displacement mechanism capable of protracting the penetrating cartridge towards the body of the patient, where protraction of the penetrating cartridge results in insertion of the subcutaneously insertable element into the body of the patient.

A foot covering in the form of a pocket or lodge slipper that allows outer footwear, e.g., shoes or boots to be removed and, with the covering in place, the conventional sock and/or foot will be protected from dirt, moisture, and other elements of nature such as thorns, rocks, splinters, etc. The slipper may be formed at least in part from elastic material which is stretchable to fit over a conventional sock. The slipper may also be formed at least in part from a rubberized material. The slipper may be flexible and foldable into a small package to be carried in a pant or coat pocket, for example. Alternatively, the slipper may be tightly rolled and carried in a small package such as a pouch or nylon bag.

There are disclosed various embodiments of surgical tacks for use in surgical procedures. The tacks generally include a head and a barrel portion extending distally from the head. Preferably the head and the barrel portion define a throughbore for receipt of a drive instrument. A thread on the head is provided to engage threads in the installation tool. A tissue thread is provided on the barrel, portion to engage tissue. Distal and proximal surfaces of the tissue thread may be oriented at various angles relative to the barrel portion. There is also disclosed an insertion instrument to insert one or more tacks as well as a method of use. There is further disclosed a model device for use in explaining the operation of the instrument.

A medical device, such as a vascular filter, composed of: a reinforced membrane unit composed of: a thin filter membrane; and fibers of reinforcement material embedded in the membrane to strengthen the filter and securely attach the fibers to the membrane.

A method of fabricating the filter by the steps of: providing a mold that can be melted, dissolved, or deformed without damaging membrane material; covering the mold with an intermediate material that is easily separated from the membrane material; covering the intermediate material with the membrane material; placing the fibers in contact with the membrane material that covers the intermediate material; covering the fibers with additional membrane material to form the membrane with embedded fibers; removing the mold by melting, dissolving, or deforming the mold; and removing the intermediate material from the membrane.

The application discloses a flexible display device. Specific mode of performance in the device comprises a flexible display panel and a rigid support plate attached to the flexible display panel; wherein the flexible display panel comprises a display area and a circuit area; the rigid support plate comprises a non-bending area and a bending area and the rigidity of bending area is lower than that of non-bending area; non-bending area comprises first sub-rigid support plate and second sub-rigid support plate and the former is used for supporting display area while the latter is used for supporting circuit area; bending area comprises support layer that comprises substrate and convex array formed from substrate and thickness of bending area is lower than or equal to that of rigid support plate. The mode of performance realizes bending in circuit area and display area and disperses extrusion pressure formed in bending area by convex array so as to prevent breakage in existing technology and extend service life of flexible display device.

A fully enclosed carton for carrying heavy loads with a reinforcement insert for the handle apertures located in the top end flaps of the carton. The paperboard reinforcing insert may be extended as a bridge across the top panel of the carton to prevent tearing of the handle apertures in the top end flaps and also tearing in the top panel of the carton when carrying a heavy load. The carton may have one or more dispensers in the top panel which may extend into an adjoining side panel. Multiple tear lines may be formed for the dispenser flap in the insert that extends across the top panel to permit easy access to the containers, such as bottles, in the carton. The paperboard reinforcing insert may have a larger aperture than the handle aperture in each top end flap to adjust for any imprecision in the alignment of the paperboard insert in forming the carton sleeve from the paperboard blank. When the paperboard insert extends across the top panel and one or more dispensers are formed in the top panel, multiple tear lines may be used to form the flaps in the insert to compensate for any imprecision in the insertion of the insert that extends across the top panel into the carton sleeve when it is being formed.

An interbody spinal implant, such as a solid-body or composite implant, includes at least one graft contact surface as one or more of the internal surfaces of the implant. The graft contact surface, for example, having at least one ridge or groove is designed to contact and promote retention and stabilization of bone growth-inducing materials placed within the internal openings of the implant body. In addition, the ridges or grooves may influence the biological processes to promote bone healing and fusion. Also disclosed are processes of fabricating the graft contact surfaces and other surface topographies on the implant.

The invention relates to a an incontinence strap (66) for treating urinary incontinence, in particular, urinary incontinence in females, that is configured such that it is flexible.

A direct expansion geothermal heat exchange unit, which can be placed in sub-surface ground and/or water, consisting of at least one insulated refrigerant liquid/fluid line, with a liquid trap at the bottom of the liquid/fluid line, with at least one un-insulated refrigerant vapor/fluid line operatively connected to the insulated liquid/fluid line at a point above the liquid trap, where the un-insulated vapor/fluid line is in thermal contact with its adjacent sub-surface surrounding elements by means of a heat conductive fill material inserted as necessary to fill any void space, in any borehole or excavated area, between the vapor/fluid line and its respective adjacent sub-surface surroundings.

Methods, apparatus and systems for producing cushioning material from sheet material. In some embodiments, the apparatus comprises horizontally aligned forming members having fins for use in pulling and processing sheet material. The sheet material can be perforated sheet material. A holder can be provided for holding sheet material in stock roll form, the holder having a cross-bar for producing resistance against the stock roll to dissipate momentum of the stock roll when the motor of the apparatus is stopped.

A method and apparatus for treating a patient having an obstruction in a first blood vessel through which blood normally flows in a given direction, at a location downstream of a branch point where the first blood vessel and, a second blood vessel branch off from a main blood vessel, by: blocking blood flow in the main blood vessel at a point upstream of the branch point; inserting into the second blood vessel a first filter adapted to pass blood while trapping debris resulting from removal of the obstruction; inserting an obstruction removal assembly into the first blood vessel and operating the assembly to at least partially break up the obstruction and produce debris; withdrawing the obstruction removal assembly from the patient's body; and then inserting into the first blood vessel a filter adapted to pass blood while trapping debris; then restoring blood flow in the main blood vessel.
