A suture and needle combination is disclosed for use during surgical and non-surgical procedures comprising a suture needle 16 with a breakaway tip 20, insertable tip 24 or reusable tip 32. Suture 10 passes freely through hollow needle 16 after a user removes needle tip (20,24, or 32) during use. This suture needle combination reduces the amount of room needed within a surgical site, reduces the length of needle 16 needed to exit tissue (for example) while suturing, and decreased trauma to at risk anatomical structures during a surgical procedure or other use.

A suturing system for receiving and retaining a suture is disclosed and includes a suture, at least one retainer, and at least one needle. Each needle is able to receive and removably retain the suture within a groove located in a tapered end. The retainer has a body that defines an aperture therethrough.
