Abstract

An access port for subcutaneous implantation is disclosed. Such an access port may comprise a body for capturing a septum for repeatedly inserting a needle therethrough into a cavity defined within the body. Further, the access port may include at least one feature structured and configured for identification of the access port subsequent to subcutaneous implantation. Methods of identifying a subcutaneously implanted access port are also disclosed. For example, a subcutaneously implanted access port may be provided and at least one feature of the subcutaneously implanted access port may be perceived. Further, the subcutaneously implanted access port may be identified in response to perceiving the at least one feature.

Claims

1-41. -41. (canceled)

42. A venous access port assembly for implantation into a patient, comprising:

a plastic housing having an outlet and a housing base,

a metal disk, and

a needle-penetrable septum, the needle-penetrable septum and the plastic housing together defining a reservoir,

wherein the metal disk is incorporated in the housing base and includes a radiopaque feature that conveys information indicative of an attribute of the assembly when an X-ray of the patient is taken after implantation so that a practitioner can be advised after implantation by the information indicative of an attribute of the assembly.

43. The assembly of claim 42, wherein the radiopaque feature is etched into the metal disk.

44. The assembly of claim 42, wherein the radiopaque feature includes an alphanumeric message.

45. The assembly of claim 42, wherein the radiopaque feature includes radiographically discernable markings applied to the metal disk.

46. The assembly of claim 42, wherein the housing includes radiotransparent material surrounding the housing base.

47. A venous access port assembly for implantation into a patient, comprising:

a housing having an outlet, and

a needle-penetrable septum, the needle-penetrable septum and the housing together defining a reservoir,

wherein;

the assembly includes at least one feature observable through interaction with X-rays subsequent to subcutaneous implantation of the assembly, and

the at least one feature conveys information indicative of an attribute of the assembly.

48. The assembly of claim 47, wherein the feature is metal and provided on an exterior of the assembly.

49. The assembly of claim 47, wherein the feature includes an alphanumeric message.

50. The assembly of claim 48, wherein the feature includes radiographically discernable markings applied to the exterior of the assembly.

51. The assembly of claim 47, wherein the housing has a base and the assembly includes radiotransparent material surrounding the base.

52. A venous access port assembly for implantation into a patient, comprising:

a housing having a discharge port, a needle-penetrable septum, and a cap securable to the housing and retaining the septum securely in the assembly, the housing has a housing base defining a bottom wall of at least one reservoir, and the housing base has an outwardly facing bottom surface, and

the housing base includes radiopaque markings, the radiopaque markings include indicia that convey information indicative of an attribute of the assembly when an X-ray of the patient is taken after implantation so that a practitioner can be advised after implantation by the indicia of the attribute of the assembly.

53. The assembly of claim 52, wherein the radiopaque markings are applied to a surface of the housing base.

54. The assembly of claim 52 wherein the radiopaque markings are applied to the outwardly facing bottom surface of the housing base.

55. The assembly of claim 52, wherein the housing includes radiotransparent material molded around the housing base.

56. The assembly of claim 52, wherein the radiopaque indicia include alphanumeric characters.

57. A venous access port assembly for implantation into a patient, comprising:

a housing and a needle-penetrable septum together defining a reservoir; and

the housing including an outlet, the housing also including a radiopaque geometry observable through interaction with X-rays subsequent to subcutaneous implantation of the assembly into the patient, the radiopaque geometry identifying an attribute of the assembly.

58. The assembly of claim 57, wherein the radiopaque geometry includes an alphanumeric message.

59. The assembly of claim 57, wherein the radiopaque geometry includes at least one radiographically discernable marking.

60. The assembly of claim 57, wherein the housing has a base and the assembly includes radiotransparent material surrounding the housing base.

61. A venous access port assembly for implantation into a patient, comprising:

a housing and a needle-penetrable septum together defining a reservoir; and

the housing including an outlet, the housing also including radiopaque markings, and the radiopaque markings including indicia that convey information indicative of an attribute of the assembly when an X-ray of the patient is taken after implantation so that a practitioner can be advised after implantation by the indicia of the attribute of the assembly.

62. The assembly of claim 61, wherein the radiopaque indicia includes an alphanumeric message.
