A guidewire has a guidewire body with a distal end and a proximal end. A balloon or other tissue anchor is disposed at or near the distal end of the guidewire, and the guidewire may be used to draw two layers of tissue into apposition by placing the guidewire through a tissue penetration, deploying the tissue anchor, and drawing proximally on the guidewire body. Optionally, the guidewire may include deployable blades for enlarging a tissue penetration as the guidewire is advanced therethrough.

The invention provides a method for gathering and showcasing validated customer reviews of online merchants. The invention is comprised of three parts: a first part being a web page plugin application; a second part being a cloud software platform; and a third part being a block chain network. When a customer makes a purchase, the plugin (embedded on merchant's website) asks them if they would like to leave a review. Once accepted, the software links the customer with the merchant's identification and they are redirected to the invention's webpage. After a review is posted it is then validated and stored on a secure ledger that is part of a block chain. Merchants are allowed to post replies that are stored on the block chain. Reviews and replies are displayed publically on the invention's website. An object of the invention is to minimize false reviews of online merchants.

An automated sprayer for spraying the walls of a shower enclosure with a liquid cleanser dispenses the cleanser using a pump and rotatable spray head. A motor drives the pump and rotates the spray head. The sprayer has a showerhead mountable housing with a hanger. The housing supports a bottle of cleanser in an inverted fashion. Cleanser is delivered from the bottle through a cleanser conduit in the piercing post into a well of the housing. The bottle is vented from the well through an air vent path in the piercing post or from a well vent outlet through the air vent path in the piercing post. An outlet valve in the well permits outflow of cleanser from the well. Various bottle caps and bottle closures are also provided to improve venting and/or limit cleanser leakage from the bottle when the bottle is installed in the housing.
