In one exemplary aspect, the present disclosure is directed to an assembly having an irrigation hand piece that includes an irrigation needle extending from a distal end. The irrigation needle is also configured to release a first fluid. The assembly further has an aspiration hand piece that includes an aspiration needle extending from a distal end. The aspiration needle has an axis and is configured to aspirate a second fluid into the assembly. The assembly has a first configuration in which the irrigation hand piece and aspiration hand piece are coupled together in a manner that causes the released first fluid from the assembly to flow coaxially about the axis of the aspiration needle and a second configuration in which the irrigation hand piece and aspiration hand piece are uncoupled which causes the released first fluid to flow substantially non-coaxial with respect to the axis of the aspiration needle.

A hard surface cleaning appliance is disclosed. The hard surface cleaning appliance includes a cleaning head with a top surface and a bottom surface. The bottom surface is adjacent a surface to be cleaned. The cleaning head disperses cleaning fluid onto the surface to be cleaned, and subsequently vacuums up the cleaning fluid and dirt from the surface to the cleaned. The hard surface cleaning appliance includes an adaptor. Adjusting the adaptor adjusts the amount of pressure the cleaning head exerts on the surface to be cleaned. Having the capability to adjust the amount of pressure the cleaning head exerts on the surface to be cleaned allows the cleaning appliance to work on uneven surfaces such as tile, brick, or stone without the cleaning head getting stuck in cracks or crevices in the surface to be cleaned.

System for relieving stress at pipe connections using external sleeve

Номер: US20140034180A1
Автор: Adam Norbert Landherr, Joseph Charles Van Ryzin, Steven Emanoel Rizea
Принадлежит: Makai Ocean Engineering Inc

A pipe attachment assembly for attaching a pipe to another structure so stresses are reduced within the assembly includes a sleeve positioned outside the pipe which is composed of a material stronger than the pipe material, and an elastomeric bonding material which fills a gap between the pipe and the sleeve. The elastomeric bonding material transfers forces which are externally imposed on the pipe to the sleeve. This reduces bending, compression, tension, or torsion of the pipe in response to external forces, which in turn reduces the risk of a pipe failure at or near the termination or a breach where the pipe forms a joint with other pipes or containers. Various configurations may further improve the transfer of shearing stresses from the pipe to the sleeve, for example varying the width and/or the shear modulus of the elastomeric bonding material along the length of the pipe.

Apparatus and methods for preventing prolapse of iris tissue through a surgical opening in the eye during an ophthalmic surgery. A flexible biocompatible polymeric shield is inserted into the anterior chamber of the eye, placed in position overlying the iris adjacent a surgical opening into the anterior chamber and is thus between the iris tissue and the surgical opening. As pressure inside the anterior chamber increases during the surgery, anterior movement of the iris toward any surgical opening in response to such pressure, also moves the shield anteriorly, such that the shield remains between the iris and the surgical opening. Thus, the shield blocks the surgical opening and prevents movement of eye material to and through the surgical opening. The surgical opening can still be accessed by surgical tools and materials from outside the eye by inserting such articles through the surgical opening and pushing such articles past the shield. 1.

A method and device for wound closure is provided. One advantage of wound closure devices and methods shown includes a simple and inexpensive modified suture with increased pullout resistance to close wounds in eyes and prevent leakage. Another advantage includes a visualization tool to aid in locating the wound on the eye. 1. A method , comprising:pressing a transparent portion of a visualization device in direct contact with an ophthalmic wound;moving fluids away from the ophthalmic wound as a result of pressure from the transparent portion to enhance visualization of the ophthalmic wound; andsuturing the ophthalmic wound while maintaining pressure of the transparent portion against the ophthalmic wound.2. The method of claim 1 , wherein pressing a transparent portion of a visualization device in direct contact with an ophthalmic wound includes pressing a transparent portion that includes a suture clearance cutaway to facilitate insertion of a suture while the substantially transparent portion is in contact with the eye; and suturing through the suture clearance cutaway.3. The method of claim 1 , wherein pressing a transparent portion of a visualization device in direct contact with an ophthalmic wound includes pressing a transparent portion that includes a pair of adjacent suture clearance cutaways to facilitate insertion of a suture while the substantially transparent portion is in contact with the eye; and suturing through the suture clearance cutaway.4. The method of claim 1 , further including engaging one or more frictional protrusions located on one side of the transparent portion with an eye to hold the transparent portion in place while suturing.5. The method of claim 1 , wherein engaging one or more frictional protrusions includes engaging one or more teeth.6. The method of claim 1 , wherein pressing a transparent portion of a visualization device in direct contact with an ophthalmic wound includes holding a handle attached to the transparent portion and ...

Various adjustable cannula systems are provided. The systems can include an adjustable cannula capable of expansion and/or contraction having an elongate body with a distal end and a proximal end. The adjustable cannula can be coupled to an upper housing and a lower housing such that rotation of the upper housing results in expansion or contraction of the adjustable cannula. The adjustable cannula can also have a proximal end having a lumen larger than a distal end lumen. A plurality of flanges can be formed in the elongate body by a plurality of slits that span a majority of a length of the cannula, including along or proximate to its proximal end and distal end. 132-. (canceled)33. A cannula system configured to be anchored in the pars plana of an eyeball , the system comprising an expandable member that increases upon application of electrical energy having a first polarity to the expandable member , and that decreases upon application of electrical energy having a second polarity to the expandable member , the second polarity opposite the first polarity.34. The cannula system of claim 33 , wherein a proximal end of the expandable member is coupled to an electrical energy source claim 33 , and wherein the expandable member increases or decreases from one gauge to another when electrical energy is applied by the electrical energy source.35. The cannula system of claim 34 , comprising the electrical energy source.36. The cannula system of claim 33 , further comprising an insulating layer configured to inhibit the electrical energy from injuring surrounding tissue.37. An adjustable cannula system comprising:a housing;an expandable member coupled to the housing, the expandable member including a proximal portion and a distal portion, wherein the proximal portion has a larger cross-sectional area than the distal portion in an unexpanded state; anda plurality of folds extending along a portion of the expandable member such that the folds form a plurality of edge points ...
