Patent number: 10207053Abstract: In one aspect of the subject invention, a drug delivery device is provided which includes a reservoir for containing a medicament and has a proximal end and a distal end, the medicament including a suspension of solids in a liquid carrier. Further, the drug delivery device includes a needle in fluid communication with the reservoir and having a distal end for injection into a patient, and a proximal end in the reservoir. An accumulation surface is defined at least partially about the needle, distally of the proximal end of the needle. The accumulation surface defines a distally-extending indentation which is sized and shaped to collect, during use, solids that come out of suspension. Advantageously, with the subject invention, the accumulation surface allows for solids to accumulate at a location spaced from the proximal end of the needle, thereby minimizing the possibility of clogging the needle.Type: GrantFiled: March 16, 2012Date of Patent: February 19, 2019Assignee: Becton, Dickinson and CompanyInventors: Roger W.

Patent number: 10117673Abstract: The present disclosure provides a pressure-depending clutching device for locating and safely positioning a needle in a body cavity. The device is capable of automatically engaging and disengaging the needle from a driving force. The device has a body with an interior space, a pressure-sensing element and a force-receiving element. The pressure-sensing element, the force-receiving element, and the complementary force-sending element form a driving force engaging mechanism for coupling the force-applying structure to the needle during operation. Before the needle reaches the target body cavity, the pressure in the needle causes the clutching device to assume an “engaged” state. When the needle reaches the body cavity, the change in pressure causes the clutching device to assume a “disengaged” state, thereby, automatically positioning the needle in the cavity to avoid overshooting.Type: GrantFiled: November 20, 2015Date of Patent: November 6, 2018Inventor: Wen-Fu Luo

Patent number: 10099044Abstract: A device for delivery of a substance (144) using energy to protect, at a site of activation, against a side effect of another substance (156) that was delivered, is being delivered, and/or will be delivered, at another site. The activation may be non-invasive, remote and the energy beam (140) may be an ultrasound beam. A first of the substances can be activated at a particular energy level, and the second is then activated at a lower level so that a population of particles bearing the first substance is not inadvertently activated during activation of the second substance. The device may comprise a system to control the levels of energy applied.Type: GrantFiled: September 27, 2012Date of Patent: October 16, 2018Assignee: Koninklijke Philips N.V.Inventors: Balasundar Iyyavu Raju, Christopher Stephen Hall, Ralf Seip, Todd Nicholas Erpelding
