  • Publication number: 20210007890
    Abstract: An apparatus includes a body, a needle, a catheter, and an actuator assembly. The needle extends distally from the body. The needle has an inner wall defining a needle lumen. The needle lumen is in fluid communication with a fluid port of the body. The catheter is slidably disposed in the needle lumen. The catheter has a catheter lumen. The first actuator assembly is configured to translate the catheter within and relative to the needle. The apparatus may also include an actuator assembly that is configured to rotate the needle relative to the body. The apparatus may be used to first deliver a leading bleb of fluid to the subretinal space in a patient's eye via the needle. The apparatus may then be used to deliver a therapeutic agent to the subretinal space in the patient's eye via the catheter.

  • Patent number: 8808325
    Abstract: A staple having a crown, a deformable leg extending from the crown, and a spring extending from the crown configured to compress tissue between the spring and the deformable member. Owing to the flexibility of the spring, the staple can accommodate a wide range of tissue thicknesses while still compressing the tissue captured therein. As a result, a single staple design can be used in a wide variety of surgical procedures thereby reducing the amount of staple designs that must be provided to the surgeon. In at least one embodiment, the staple includes a crushable member. This crushable member can include a plastically deformable first portion and an elastically deformable second portion. The present invention can also include, in various embodiments, a crown, a first deformable member extending from the crown, and means for compressing the tissue against the first deformable member.

  • Patent number: 7819877
    Abstract: A bone plating apparatus includes a handle having extending therefrom a tissue expander for insertion through a skin incision and through the subcutaneous tissue surrounding a fractured bone. A bone plate may be secured to the handle during advancement of the tissue expander so as to deliver the bone plate to a desired location proximate to the fractured bone. Both the tissue expander and the bone plate may be advanced to the desired location proximate to the fractured bone under the visualization of an endoscope. A screw alignment jig is secured to the handle and has a guide hole which aligns with an access hole of the tissue expander. The alignment of the guide hole and the access hole allow for percutaneous screw insertion into the delivered bone plate. A method for plating a fractured bone is also disclosed.

  • Patent number: 7223239
    Abstract: A medical device for use on a bodily organ includes a concave support element that is removably attachable to the surface of the bodily organ, thereby defining an enclosed space adjacent to the bodily organ. The enclosed space is fluidly connected to a fluid management system for circulating a fluid inside of the enclosed space. The medical device also has an energy transfer element mounted to the concave support element and electrically connected to a control unit. In some embodiments, the energy transfer element transmits intense ultrasound energy in a frequency range of 1–30 megahertz, and the fluid acoustically couples the energy transfer element to the bodily organ, and the fluid also cools the energy transfer element.
